IBM System Storage™ DS Storage Manager version 10.70.x5.25 for Microsoft Windows Server 2008 SP2 - x86 and Windows Server 2003 SP2 - x86 (32bit) operating system environments. Important: A problem causing recursive reboots exists while using 7.36.08 and 7.36.12 firmware on IBM System Storage DS4000 or DS5000 systems. This problem is fixed in 7.36.14.xx and above firmware. All subsystems currently using 7.36.08 and 7.36.12 firmware MUST run a file system check tool (DbFix) before and after the firmware upgrade to 7.36.14.xx or higher. Instructions for obtaining and using DbFix are contained in the 7.36.14.xx or higher firmware package. Carefully read the firmware readme and the DbFix instructions before upgrading to firmware 7.36.14.xx or higher. For subsystems with firmware level 7.36.08 or 7.36.12, configuration changes should be avoided until a firmware upgrade to 7.36.14.xx or higher has been completed successfully. Subsystems not currently using 7.36.08 or 7.36.12 do not need to run DbFix prior to upgrading to 7.36.14.xx or higher. DbFix may be run after upgrading to 7.36.14.xx or higher, but it is not required. DbFix is only applicable to subsystems using 7.36.xx.xx or greater firmware. If problems are experienced using DbFix or the resulting message received is “Check Failed…”, DO NOT upgrade your firmware and contact IBM support before taking any further actions.

For the DS4400 and the DS4100 storage subsystems - all models (Standard /dual controller and Single Controller), the controller firmware version 06.12.xx.xx and later must be used. 2. The DS4300 with Single Controller option(M/T 1722-6LU,6LX,and 6LJ), FAStT200 (M/T 3542-all models) and FAStT500 (M/T 3552-all models) storage subsystems can no longer be managed by DS Storage Manager version 10.50.xx.23 and higher. 3. For the DS3x00 storage subsystems, please refer to the readme files that are posted in the IBM DS3000 System Storage support web site for the latest information about their usage, limitations or configurations. http://www.ibm.com/systems/support/storage/disk ======================================================================= 1.2 Limitations ---------------- IMPORTANT: The listed limitations are cumulative. However, they are listed by the DS4000/DS5000 storage subsystem controller firmware and Storage Manager host software releases to indicate which controller firmware and Storage Manager host software release that they were first seen and documented. New limitations with Storage Manager version 10.70.xx.25 release (controller firmware 07.70.xx.xx). 1. Kernel Panic reported on Linux SLES10 SP3 during controller failover. Probability of this issue happening in the field is low. Workaround: Avoid placing controllers online/offline frequently. Novell was informed about this issue. Opened Novell Bugzilla NVBZ589196. 2. CHECK CONDITION b/4e/0 returned during ESM download on DS5000 The interposer running LP1160 firmware is reporting an Overlapped Command (0B/4E/00) for a Read Command containing an OXID that was very recently used for a previous read command on the same loop to the same ALPA. In almost all cases, this command will be re-driven successfully by the controller. Impact should be negligible. Workaround: Can be avoided by halting Volume I/O prior to downloading ESM firmware. 3. If a host sees RAID volumes from the same RAID module that are discovered through different interface protocols (fibre/SAS/iSCSI) failovers will not occur properly and hosts IOs will error out. If the user does not map volumes to a host that can be seen through different host interfaces this problem will not occur. Workaround: Place controller online and reboot the server to see all volumes again. 4. Linux guest OS reported I/O error during Controller Firmware Upgrade on ESX4.1 with Qlogic HBA. The user will see I/O errors during controller activation from the guest OS due to mapped devices becoming inaccessible and offline. Workaround: This issue occurs on various Linux guest OSes, so to avoid the issue the user should perform an offline (no I/O to controllers) controller firmware upgrade. 5. I/O Error on Linux RH 4.8 after rebooting controller on DS3500 iSCSI. The devices will be disconnected from the host until the iSCSI sessions are re-established. workaround: Restart the iSCSI service. Configure the iSCSI service to start automatically on boot. 6. CFW Upgrade on 4.1 w/SLES 11 fails with IO error on SLES 11 Guest partition. This issue occurred if there is filesystem volume in SLES11 VM. User will see I/O errors and Filesystem volumes in SLES11 VMs will be changed to read-only mode. Workaround: User can perform controller FW upgrade with either no I/O running on SLES11 VM or no Filesystem created in SLES11 VMs. 7. "gnome-main-menu" crashes unexpectedly while install HSW on Suse 10. The crashes appear to happen randomly with other applications as well.  After the crash the menu reloads automatically.  Dismiss the prompt and the host will reload the application.  This problem appears to be a vendor issue. 8. I/O errors on RHEL 4.8 guests on VMware 4.1 during controller reset. VMware has suggested VMware 4.1 P01 may resolve this issue. No support was issued for RHEL 4.8 guests under VMware 4.1 over SAS. Workaround: Use RHEL 5.5. 9. VMWare guest OS not accessible on iSCSI DS3524 (VMware SR 1544798051, VMware PR 582256). VMware has suggested VMware 4.1 P01 may resolve this issue. Workaround: Use Fibre Channel or SAS connectivity. 10. When DMMP is running in a BladeCenter SAS environment, I/O errors occur during failover and controller firmware operations. Support for Device Mapper and SLES 11.1 SAS has been restricted and will not be published. Workaround: Install RDAC. 11. SLES11.1ppc SAN boot fails on PS700 with 10 Gb Qlogic ethernet to DS3512. After configuration and install of Linux on a LUN using software iSCSI, the JS blade will not boot into the OS. Workaround: Use local boot, SAS or Fibre Channel. 12. ‘No response’ messages from Device Mapper devices with volumes on non-preferred path. Any I/O operations against volumes mapped to failed devices will timeout or hang. Workaround: This problem requires the host to be rebooted in order to restart I/O successfully. Update SLES11.1 to maintenance update 20101008 containing kernel version 2.6.32.23-0.3.1. Note that this kernel version has not been fully certified by LSI and should only be used if this issue is encountered. Bugzilla #650593 contains issue details and fix provided by Novell. 13. LifeKeeper 7.2.0 recovery kits require multiple host ports to use SCSI reservations. Workaround: Use two single port SAS HBAs. In this case each port will be represented as a host, and LifeKeeper will identify both separately. Another way to avoid the issue is to use MPP as the failover driver. 14. Unexpected "jexec" messages during mpp installation/un-installation on SLES 11.1. Workaround: None - https://bugzilla.novell.com/show_bug.cgi?id=651156 15. I/O write errors on mounted LifeKeeper volumes before node resources transfers to another node. recovery: I/O can be restarted as soon as node resources are transferred to another node in the cluster. Workaround: None. 16. Solaris 10u8 guest OS disks become inaccessible on ESX35u5 during sysReboot on array controller. This can be avoided by not using raw device mappings and instead using virtual disks. If raw device mappings are required, they must be used with virtual compatability mode selected when adding the disks to the guest OS. Workaround: None. 17. Solaris 10u8 guest OSes reported I/O error during Controller Firmware Upgrade on ESX35U5 with Qlogic HBA. Permanent restriction. Workaround: Perform upgrade with no I/O. 18. Solaris guest OS reported I/O error during Controller reset on ESX35U5. The only recovery method is to rebooting the failed VM host. Permanent restriction. New limitations with Storage Manager version 10.70.xx.10 release (controller firmware 07.70.xx.xx). 1. Storage Manager “Error 1000 - Could not communicate with the storage...." can occur when actions such as clearing the configuration on a large system (i.e. 448 drives with a DS5300). The Storage Manager has a 120 second timeout and retries 2 more times when retrieving status. Some actions such as this may take 8 minutes or longer. 2. Array Management Window shows 2048 volume copies allowed when only 2047 maximum volume copies can be created. For a given array, at least one source volume will be present for the volume copy feature; hence, the actual number of “copy relationships” is one less than the maximum volume allowed. 3. FDE Drive in “Security Locked” state is reported as “incompatible” state in the drive profile. The drive can be recovered by importing the correct lock key. 4. Deselecting product components using keyboard when installing Storage Manager still installs them. You will have to use mouse for individual component selection. New limitations with Storage Manager version 10.60.xx.17 release (controller firmware 07.60.xx.xx). 1. This version of the Storage Manager installation package includes the IBM Storage Manager Profiler. This is also referred to as Support Monitor in some of the IBM publications. The following system restrictions apply: Note: Do not use laptops or I/O-attached hosts for installing the IBM Storage Manager Profiler unless these items fulfill all of the following requirements. 1. Minimum 1GB memory, 1.5 GB preferred 2. Minimum 1GB hard drive space, 1.5 GB preferred 3. On average 15 to 20 minutes installation duration 4. Static IP address required 5. The Storage Manager Profiler is installed by default with the IBM DS Storage Manager Install Anywhere (SMIA) package with the Typical (Full Installation) selection. To not install the Storage Manager Profiler, select Custom then deselect Support Monitor. 6. A pre-existing MySQL database on the host must be manually uninstalled before you can install the Storage Manager Profiler. 7. The Storage Manager Profiler installation includes the Apache Tomcat webserver application. Any other pre-existing applications that use Apache Tomcat must be uninstalled before you install the Storage Manager Profiler. 8. Make sure the Storage Manager Profiler directory structure is removed from antivirus and backup applications. 9. MS Internet Explorer and Mozilla Firefox are the only two Web browsers supported with the Storage Manager Profiler client application. 10. By default, the Storage Manager Profiler polls all storage subsystems for storage subsystem support data every day at 2:00am. Ensure that there is not heavy usage of the storage subsystem during this time period. This collection time schedule can be modified to start during the window that the storage subsystem has light usage by pointing your Web browser at http://localhost:9000/ and click on the Calendar icon to schedule the data collection frequencies and time. 11. The Storage Manager Profiler typically takes five minutes to seven minutes to collect data, but the time can increase for larger configurations. There have been exceptional instances where storage arrays took up to 20 minutes to capture the data when capturing the drive information. 12. If you have a large system, gathering support data takes longer, and the compressed files are larger. The Storage Manager Profiler compresses the collection data file to be between 2 MB and 5 MB. 13. Monitor each storage subsystem from one Storage Manager Profiler instance. Gathering data from a storage subsystem with multiple Storage Manager Profiler instances can cause problems. No mechanisms exist that prevent multiple Storage Manager Profiler instances from trying to find data from the same storage subsystem. 14. When multiple Storage Manager instances are installed in the environment, do not define the same storage subsystem twice in the Storage Manager Enterprise Management window. 15. The data collection process of the Storage Manager Profiler is multi- threaded with a polling mechanism in place to find the maximum number of storage subsystems at pre-defined timing intervals. The polling mechanism is not sequential. For example, if the upper limit on the number of storage subsystems from which the Storage Manager Profiler can find data is 20, and 60 storage subsystems are defined, 20 threads are gathered immediately, while the data from the remaining 40 storage subsystems are gathered as resources became available. The Storage Manager Profiler supports at least 10 storage subsystems. 16. The Storage Manager Profiler does not support in-band management of storage subsystems. 17. The only function that the Storage Manager Profiler supports is the Support Monitor. 18. A minimum of 06.19.xx.xx controller firmware is required to use the Storage Manager Profiler. 2. The online help of the Command Line Interface commands (SMcli commands) incorrectly showed the parameters of certain SMcli commands. The parameters that were shown incorrectly belong to the "disk" type parameter such as Drive, Drivechannels, DiskDrives, repositoryDrives ... These parameters were incorrectly shown with the additional word "disk" such as diskDrive, DiskDriveChannels, repositoryDiskDrive ... The SMcli command syntax checking engine will display the correct syntax for these parameters. Make the modifications as suggested by the SMcli command syntax checking engine. One can also refer to the pdf copy of the Command Line Interface and Script Commands Programming Guide - IBM System Storage DS4200, DS4700, and DS5000 in the IBM DS support web site for help on the SMcli command syntax. 3. The suggested recovery path in the mis-wired guru event might send the user down either the wrong path or very long path when trying to fix the first mis-wired port. The work-around is to use the cabling diagram in the EXP5060 Installation, User's and Maintenance guide or the DS5100 and DS5300 Installation, User's and Maintenance guide publications to fix the cabling mis-wired error. The pdf version of these pubs are available in the IBM DS support web site. New limitations with Storage Manager version 10.60.xx.11 release (controller firmware 07.60.xx.xx). 1. If port 1 of the iSCSI host interface is disconnected when the iSCSI configuration window is first opened, the status of port 1 shows as connected. If you switch to port 2 and back to port 1, the status will refresh and port 1 will show as disconnected. 2. When modifying the iSCSI host port attributes there can be a delay of up to 3 minutes if the port is inactive. If possible, connect a cable between the iSCSI host port and a switch prior to configuring any parameters. 3. When applying the Premium feature keys to enable the 64 or 112 drive attachment to the DS5020 subsystem, the "drive slot limit" premium feature entry in the Premium Features and Feature Pack Information window will not be updated to reflect the maximum number of drives that can be attached to the subsystem (either 64 or 112). In addition, when trying to attach more drives than the DS5020 is currently allowed, the "drive slot limit" premium feature entry in the Premium Features and Feature Pack Information window will be displayed with the "out of compliance status". To view the maximum number of drives that can be attached to a DS5020, obtain the Storage Subsystem profile and search for the following info. Drive Limit Management: Number of drive slots discovered: 32 Number of drive slots allowed: 112 Note: The controllers use the discovered drive slot in the subsystem configuration number to determine whether the maximum number of drives limit is exceed or not instead of the actual number of drives installed. For example, if there are two drive expansion enclosures attached to the DS5020, the number of discovered drive slot will be 42 which is exceeding the limit of 32 that the DS5020 supported as standard feature even the total number of installed drives actually installed in the subsystem is 32 or less. In this case, the drive slot limit will be shown with the status Out-of-Compliance until the DS5020 33-64 drive attach premium feature key is applied. (XB014946) 4. The Configure iSCSI host port window always displayed the iSCSI host port number with respect to the installed iSCSI port in the subsystem only. It does not take into account of other types of host port installed in the subsystem. Its port counting starts with the first discovered iSCSI port in the subsystem instead of the first host port installed in the subsystem per controller host port scanning order. For example, the DS5020 controller with iSCSI port option will have the port labeled as ports 1 and 2 per controller in the Configure iSCSI host port window instead of as ports 3 and 4 because there are two FC ports installed in the controller boards. However, the MEL entries will refer to the iSCSI posts as ports 3 and 4 instead of as ports 1 and 2 as referred to in the Configure iSCSI host port window. Similarly, in the DS5100 and DS5300 subsystems, the iSCSI host ports in HIC slot 2 will be referred to as ports 1 and 2 in the Configure iSCSI host port window and ports 5 and 6 in the MEL if the FC host card is installed in HIC slot 1. (XB014900) 5. The Premium Feature activation confirmation window for Drive Security (FDE) feature activation key will show the feature as "Unknown capacity". Click Ok to confirm that you want to go ahead with the enablement of the Drive Security (FDE) feature. 6. When doing a Refresh DHCP operation in the Configure iSCSI port window, and the iSCSI port is unable to contact the DHCP server, the following inconsistent informational Mel events can be reported; - MEL 1810 DHCP failure - MEL 1807 IP address failure - MEL 1811 DHCP success. For this error to occur, the following specific conditions and sequence must have been met: - Before enabling DHCP, static addressing was used on the port and that static address is still valid on the network. - The port was able to contact the DCHP server and acquire an address. - Contact with the DHCP server is lost. - The user performs the Refresh DHCP operation from DS Storage Manager Client. - Contact with the DHCP server does not come back during the DHCP refresh operation and timeouts. Check the network connection to your iSCSI port and the status of the DHCP server before attempting the Refresh DHCP operation again. New limitations with Storage Manager Upgrade Utility package version 10.60.xx.05 release (controller firmware 07.60.xx.xx). 1. none New limitations with Storage Manager Upgrade Utility package version 10.50.xx.23 release (controller firmware 07.50.xx.xx). 1. The Storage Manager on-line help contains inaccurate information about locking Encryption Capable drives. The current on-line help states "Use this command to set the new security key to lock all of the Encryption capable drives." The on-line help text should state " Use this command to set the security key that is used throughout the storage subsystem to implement the Disk Encryption premium feature. When any security-capable drive in the storage subsystem is assigned to a secured array, that drive will be security-enabled using the security key." 2. The Storage Manager Re-key operations can fail when there are Encryption Capable drives present in the system that are spun down. When drives are marked for export in a storage subsystem the drives are spun down. Attempting to generate a lock key with spun down drives will fail. Remove the exported drives from the subsystem and retry the operation. 3. When using the SMcli to create an Encryption drive security key, the SMcli command will not save the security key in a default location and a separate location at the same time. The new security key is saved in the location the SMcli was executed from if the command does not include a file location with a fully qualified path. 4. The Storage Manager Controller Firmware upgrade status message can be misleading. The Storage Manager Controller Firmware upgrade screen will report a controller is running an unsupported firmware version if the subsystem is unresponsive at the time of the upgrade. New limitations with Storage Manager Upgrade Utility package version 10.50.xx.19 release (controller firmware 07.50.xx.xx). 1. The DS Storage Manager version 10.50.xx.19 will not manage DS4000 Storage Subsystems with Controller firmware levels prior to v5.40.xx.xx. 2. Start of day (a controller reboot) can take a very long time, up to 20 minutes, after a subsystem clear configuration on a DS5000 subsystem. This occurs on very large configurations, now that the DS5000 can support up to 448 drives, and can be exacerbated if there are SATA drives. 3. Veritas cluster server node failure when fast fail is enabled. Recommend setting dmp_fast_fail HBA flag to OFF. Frequency of this causing a node failure is low unless the storage subsystem is experiencing repeated controller failover conditions. 4. Brocade HBA does not support direct attach to storage subsystem. 5. At times the link is not restored when inserting a drive side cable into a DS5000 controller, a data rate mismatch occurs. Try reseating the cable again to clear the condition. 6. Due to a timing issue with controller firmware, using SMcli or the script engine to create LUNs and set LUN attributes will sometimes end with a script error. 7. Mapping host port identifiers to host via Script Editor hangs; fails via CLI with "... error code 1”. This will occur when using the CLI/script engine to create an initial host port mapping. 8. Under certain high stress conditions controller firmware upgrade will fail when volumes do not get transferred to the alternate controller quick enough. Upgrade controller firmware during maintenance windows or under low stress IO conditions. New limitations with Storage Manager Upgrade Utility package version 10.36.xx.13 release (controller firmware 07.36.xx.xx). 1. None New limitations with Storage Manager Upgrade Utility package version 10.36.xx.07b release (controller firmware 07.36.xx.xx). 1. Upgrade of DS4000 to 7.xx.xx.xx using the upgrade tool with non-English OSes will end with an error. The current firmware column still shows the previous version, pending version will show 7.xx.xx.xx, instead of 'none'. Checking the upgrade tool log you will find: [12.11.2008 08:51:16] [rey-ds4700-1] [SUPPORT_SERVICES] [DownloadAndActivate] activation failed There are two ways to check the content of this log: 1. As long as the upgrade tool is still open: Use the 'View log' button 2. If the upgrade tool was closed already: For windows all logs can be found in this folder: C:\Program Files\IBM_DS4000FirmwareUpgrade\client For other operating systems, check in the appropriate folder. Syntax of the name is similar to 20081114_1501.log. Then check the profile. Here the new firmware can be found as pending: Current configuration: Firmware version: 06.60.17.00 NVSRAM version: N1814D470R916V17.dlp Pending configuration: Staged firmware download supported: Yes Firmware version: 07.36.12.00 NVSRAM version: N1814D47R1036V12.dlp This shows that firmware was loaded to controller but not yet activated. Workaround: After checking the items listed in Details section, activate the loaded firmware using this script command: activate storageSubsystem firmware; Mark the affected system in the Enterprise Management window of the Storage Manager. In the menu, go to Tools -> Execute script. A new window will show up. Paste the command in the upper part of this window and choose Tools -> Execute only. The activation will take a while and the controller will reboot. New limitations with Storage Manager Installer (SMIA) package version 10.36.xx.07 release. 1. With Windows Vista and Windows Server 2008, when you try to write a file using the SMcli command, the command reports that the file has been written, but the file was not written. The SMcli should issue an error code or a statement that the file was not written to the disk. Disable the Use User Account Control (UAC) option, or start the DOS prompt in an administrator mode, which gives you permission to write to the disk. Try to write the file again. New limitations with Storage Manager Installer (SMIA) package version 10.30.xx.09 release. 1. Using VDS/VSS utilities (diskraid and diskpart) to create and map volumes may not immediately see the LUNs listed on the host due to PnP taking time to scan for the devices. Wait for the devices to show up in device manager prior to using diskpart. 2. When writing an SMcli command file, the command reports that the file is written, but you cannot find the file. User Account Control is enabled on the host, and it does not allow you to modify any files on the hard drive without permission. Disable this control, and rerun the SMcli command. 3. If you use a storage array as a boot device for the Windows Server 2003 operating system, you cannot use the hibernation feature. New limitations with Storage Manager Installer (SMIA) package version 10.15.xx.08 release. 1. Reconfiguration operation (DRM) is delayed under some circumstances. When a drive fails before the DRM completes, it can take up to eight times as long for the DRM to complete. DRM reconfigurations to RAID 6 have the longest impact since there are four times as many calculations and writes that have to occur compared to other RAID levels. 2. Host Software display of controller current rate is wrong below 4Gbps. Host Software Client - AMW - Logical/Physical View - Controller Properties - Host Interfaces - Current rate is displaying "Not Available" when the controller negotiated speed is 2Gbps. When the controller negotiated speed is reduced to 1GBs, the Current rate displays "2Gbps" New limitations with Storage Manager Installer (SMIA) package version 10.10.xx.xx release (controller firmware 07.10.xx.xx). 1. Controller Alarm Bell icon does not appear as a flashing icon indicator on the screen to get the user's attention but the icon does change appearances. 2. Miswire of drive tray cabling with DS4700 and DS4200 can cause continuous reboot of a controller. To correct this situation, power down the subsystem, cable the drive trays correctly, and power the subsystem back up. 3. Controller button may appeared enabled and mislead the user that a controller is selected where in fact, a controller was not highlighted for the button to appear ready. 4. Search key is not marked correctly in that page due a JavaHelp Bug with JavaHelp 2.0_01. A search for keyword "profile" ended with phase "prese 'nting p' rofile" being marked. 5. storageArrayProfile.txt should be renamed as storageSubsystemProfile.txt in Support Data. 6. Bullets Incorrectly Placed in Volume Modification Help Page 7. Unable to Escape out of Help Display. User will be required to close the window by using window close procedure (exit, etc.) 8. Bullets and Descriptions not aligned into same line in "Viewing mirror properties". 9. The Help window is not getting refreshed properly when using the AMW.Help window. Workaround is to close and reopen Storage Manager client. 10. CLI command failure for creation of volume(s) if capacity parameter syntax is not specified. A space will need to be used between the integer value and the units used in the capacity option of this command or, "create volume volumeGroup[4] capacity=15 GB…". 11. Customer will see high ITW counts displayed in GUI (RLS feature) and logs (files) for diagnostics (support bundle, DDC, etc.) and may be concerned that he has a problem. This will not cause a Critical MEL event. Known problem previously restricted, when a DS4700 or DS4200 controller reboots, these counters increment. 12. Single tray powercycle during IO activity causes drives in tray to become failed. Customer may see loss of drive (failed) due to timing issue of drive detection & spin-up of the drive. There are one of two conditions that result on power-up: - (Most likely) Drive will be marked as optimal/missing with the piece failed, or - (rarely) Drive will be marked as failed with the piece failed. Workaround is to unfail (revive) drive which restarts reconstruction of all pieces. 13. Event log critical Event 6402 was reported after creating 64 mirror relations. Eventually, the mirror state transitions to synchronizing and proceeds to completion on mirror creation. Workaround is to ignore the MEL logging since this occurs on creation of mirror volumes. 14. Reconfiguration operations during host IO may result in IO errors when arrays contain more than 32 LUNs. These operations include Dynamic Capacity Expansion, Defragmentation, Dynamic Volume Expansion, Dynamic RAID Migration. The workaround is to quiesce host IO activity during reconfiguration. 15. Heavy IO to a narrow volume group of SATA drives can result in host IO timeouts. A narrow volume group refers to an array built of very few drives; namely 1 drive RAID 0, 1x1 RAID 1, and 2 + 1 RAID 5. The workaround is to build arrays of SATA drives out of 4 + 1 or greater. 16. When managing the storage subsystem in-band, the upgrade utility will show the upgrade as failed. This is because of the update and reboot of the controllers when activating the new firmware. SMagent is not dynamic and will need to be restarted to reconnect to the storage subsystem. 17. Selecting and dragging text within the storage profile window causes the window to be continuously refreshed. Work around is to select and copy, do not drag the text. 18. When configuring alerts through the task assistant, the option stays open after selecting OK. The window only closes when the cancel button is selected. 19. The Performance Monitor displays error messages when the storage subsystem is experiencing exception conditions. The performance monitor has a lower execution priority within the controller firmware than responding to system IO and can experience internal timeouts under these conditions. 20. Critical MEL event (6402 - Data on mirrored pair unsynchronized) can occur under certain circumstances with synchronous RVM. The most likely scenario is when both primary and secondary are on a remote mirror and an error occurs with access to that host. Resynchronization should occur automatically, when automatic resynchronization is selected for a mirror relationship. However if any of the host sites should go down during this interval, recovery by the user is required. 21. A persistent miswire condition is erroneously reported through the recovery guru even though the subsystem is properly wired. The frequency of occurrence is low and is associated with an ESM firmware download or other reboot of the ESM. The ESM that is reporting the problem must be reseated to eliminate the false reporting. Not all miswire conditions are erroneous and must be evaluated to determine the nature of the error. 22. Drive path loss of redundancy has been reported during ESM download. This occurs when a drive port is bypassed. In some instances this is persistent until the drive is reconstructed. In other cases it can be recovered through an ESM reboot (second ESM download, ESM pull and replace). 23. Unexpected drive states have been observed during power cycle testing due to internal controller firmware contention when flushing MEL events to disk. The drives have been observed as reconstructing or replaced when they should have been reported as failed. Also volume groups have been reported degraded when all drives were assigned and optimal. An indication that this is the situation would be when drive reconstruction has not completed in the expected amount of time and does not appear to be making any progress. The work around is to reboot the controller owning the volume where the reconstruction has stalled. 24. Sometimes when an ESM is inserted a drive's fault line is asserted briefly. The fault line almost immediately returns to inactive, but the ESMs may bypass the drive. In these circumstances, the administrator will have to reconstruct the failed drive. 25. After a drive fail, a manually initiated copyback to a global hot spare may also fail. The work around is to remove the failed drive and reinsert it, then the copyback should resume and complete successfully. 26. When an erronieous miswire condition occurs (as mentioned above in 21), the recovery guru reports the miswire on one controller but not on the other. In this situation, ignore the other controller and use the information supplied by the controller reporting the problem. 27. Occasionally a controller firmware upgrade to 07.10 will unexpectedly reboot a controller an extra time. This could generate a diagnostic data capture, however the firmware upgrade is always successful. 28. When managing previous releases of firmware (06.19 and prior), "working" gets displayed as "worki" during volume creation. 29. The Performance Monitor error window does not come to the front. You must minimize all other foreground windows to get to the error popup window. 30. When a disk array is in a degraded state, the array will report "needs attention" to both the EMW and the AMW. After taking appropriate corrective action, the AMW view of the array will report "fixing" but the EMW state remains at "needs attention". Both statuses are valid, when the fault state is resolved both views will change to "optimal". 31. Storage subsystem loses in-band connectivity during volume creation. This is caused by the controller logout to all hosts that are in the default host group when those hosts have QLogic HBAs which is not tolerant of the controller initiated logout. The work around is to first create the host group and host port mappings prior to creation of volumes. Then on volume creation avoid using the default host group. 32. When defining additional LUN mappings to a host, the volume name moves down to the bottom of the visible list making it difficult to keep track of the list. 33. A Windows server will experience a Blue Screen and will need to be rebooted when one or more controllers go offline in a storage subsystem. A LUN/path may be in the process of being removed because an HBA has not reestablished a login with the controller and the PnP process will remove all LUNs associated with that path. The timing of this should not be seen unless the customer is experiencing major problems with controllers going into offline states. 34. With SMProvider installed, the disk management on the server does not complete within 1 hour for a configuration of 20 or more storage subsystems attached on the subnet. This is an issue with the auto-discovery of storage IP addresses by the SMProvider that supports the VDS/VSS feature of Windows. On installation of the SMProvider, add all of the IP addresses for the storage subsystems into the registry. On reboot, the registry contains the list of IP addresses and avoids the auto-discovery delay. The registry location is: HKEY_LOCAL_MACHINE\SOFTWARE\Storage\SMprovider /v IpAddresses /t REG_SZ /d If the value is empty, the providers will use the auto-discovery method. 35. Result of an installation not completing normally because of a crash, blue screen, or other interruption will prevent the SMclient from being able to uninstall. This is because the InstallAnywhere program writes to the ZeroG registry file at the very end of the installation process. Reinstall the package to overwrite the installation and populate the ZeroG registry. 36. Using ALT-Q to access the QLogic HBA BIOS will hang the host, use CTL-Q instead. 37. Intermittently the flashcopy utility using the VSS provider fails to create persistent flashcopies. The flashcopy volume is created at the storage subsystem and the volume mappings complete successfully, but after about one minute the vshadow utility removes the volume because Microsoft's PnP driver does not detect the flashcopy volume in time. If a flashcopy failure has occurred, or the limit on flashcopies has been reached, remove any unnecessary flashcopies on the storage subsystem and retry the failed flashcopy request. Please note that some utilities such as NetBackup do not automatically clean up the failed request by removing these failed flashcopies from the storage array. 38. Startup of MS DISKRAID utility executing through VDS occasionally reports an error. The following message is reported: "Diskraid encountered a fatal error while initializing. The following information may help diagnose the error: Error: 0x80080005 Location Code: 2" The server must be rebooted to recover, shutdown and restart of the VSS/VDS service does not fix the problem. 39. Configuring separate Email alerts when two Enterprise management windows are open on the same host will cause the alerts to disappear if one of the Enterprise windows is shut down and then restarted. It is recommended that if multiple Enterprise management windows needs to be open, that they are open on separate Hosts which will indeed allow the configuration of alerts to be saved if one of the enterprise management windows is shut down and restarted. Legacy restrictions that are still applicable: 1. Reflected Fibre Channel (FC) OPN frames occurs when intermixing the EXP810, EXP710 and EXP100s behind DS4700 or DS4800 storage subsystems. This behavior causes excessive drive side timeout, drive side link down and drive side link up events be posted in the DS4000 storage subsystem Event log (MEL.) It might also cause drives to be by-passed or failed by the controller. NEW DRIVE SIDE FC CABLING REQUIREMENT MUST BE ADHERED TO WHEN HAVING EXP100 CONNECTED TO THE DS4700 OR DS4800 STORAGE SUBSYSTEMS. Please refer to the latest version of the Installation, User's and Maintenance Guide for these storage subsystems that are posted in the IBM DS4000 Support web site for more information. http://www.ibm.com/systems/support/storage/disk/ 2. Can not increase the capacity of RAID arrays. RAID arrays with certain combinations of selected segment size and number of drives that made up the arrays will exceed the available working space in controller dacstore, causing a reconfiguration request (like expanding the capacity of the array) to be denied. These combinations are generally the largest segment size (512KB) with the number of drives in the array is 15 drives or more. There is no work-around. C324144 105008 3. Interoperability problem between the Tachyon DX2 chip in the DS4500 and the DS4300 storage subsystem controllers and the Emulex SOC 422 chip in the EXP810 expansion enclosure ESMs causing up to 5 Fibre Channel loop type errors to be posted in the DS4000 storage subsystem Major Event Log during a 24 hour period. There is a small window in the SOC 422 chip that multiple devices can be opened at one time. This ultimately leads to Fibre Channel loop errors of Fibre Channel link up/down, Drive returned CHECK CONDITION, and Timeout on drive side of controller. IBM recommends the use of the Read-Link-Status function to monitor drive loop for any problems in the drive loop/channel. There is no work-around. 4. The single digit of the Enclosure IDs for all enclosures (including the DS4000 storage subsystem with internal drive slots) in a given redundant drive loop/channel pair must be unique. For example, with four enclosures attached to the DS4300, the correct enclosure ID settings should be x1, x2, x3, and x4 (where x can be any digit that can be set). Examples of incorrect settings would be 11, 21, 31, and 41 or 12, 22, 32, and 62. These examples are incorrect because the x1 digits are the same in all enclosure IDs (either 1 or 2). If you do not set the single digit of the enclosure IDs to be unique among enclosures in a redundant drive loop/channel pair, then drive loop/channel errors might be randomly posted in the DS4000 subsystem Major Event Log (MEL), especially in the cases where the DS4300 storage subsystems are connected to EXP810s and EXP100s. In addition, enclosure IDs with same single digits in a redundant drive loop/channel pair will cause the DS4000 subsystem controller to assign a soft AL_PA address to devices in the redundant drive loop/channel pair. The problem with soft AL_PA addressing is that AL_PA address assignment can change between LIPs. This possibility increases the difficulty of troubleshooting drive loop problems because it is difficult to ascertain whether the same device with a different address or a different device might be causing a problem. 5. In DS4000 storage subsystem configurations with controller firmware 6.15.2x.xx and higher installed, the performance of write intense workloads such as sequential Tape restores to DS4000 Logical drives with large I/O request sizes (e.g. 256kB) is degraded if the DS4000 logical drives are created with small segment sizes such as 8KB or 16KB. The work around is to create the DS4000 logical drives with segment size of 64KB or higher. 6. Do not pull or insert drives during the drive firmware download. In addition, ALL I/Os must also be stopped during the drive firmware download. Otherwise, drives may be shown as missing, unavailable or failed. 7. Do not perform other storage management tasks, such as creating or deleting logical drives, reconstructing arrays, and so on, while downloading the DS4000 storage subsystem controller firmware and DS4000 EXP ESM firmware. It is recommended that you close all storage management sessions (other than the session that you use to upgrade the firmware) to the DS4000 storage subsystem that you plan to update. 8. For Microsoft Windows Server 2003 R2 operating systems. When loading the Microsoft Hot fix KB916048, required in installing Storage Manager, if the IBM xSeries Server hangs during reboot it may be resolved by using the latest Broadcom driver for the Bcom HT1000. ======================================================================== 1.3 Enhancements ----------------- Host type VMWARE has been added to NVSRAM as an additional host type. DS4200 and DS4700 will use index 21 All other supported systems will use index 16 Although not required, if using a Linux host type for a VMWARE host, it is recommended to move to the VMWARE host type since any upgrading of controller firmware and NVSRAM would continue to require running scripts, whereas using the VMWARE host type does not require running scripts. The DS Storage Manager version 10.70.xx.10 (and 10.70.xx.25) host software in conjunction with controller firmware version 7.70.23.xx and higher provides support for - Support for SSD drives in the DS5020 storage subsystem. - Storage subsystem password required for all subsystems running 7.70.xx.xx controller firmware.

CURRENTLY, THE ONLY DS4000 STORAGE SUBSYSTEMS THAT ARE SUPPORTED BY THE 06.12.XX.XX CONTROLLER FIRMWARE VERSION ARE THE DS4100 - ALL MODELS, THE DS4300 WITH STANDARD (DUAL CONTROLLER) OR TURBO OPTIONS, THE DS4400 AND THE DS4500. DO NOT DOWNLOAD THIS CONTROLLER FIRMWARE ON ANY OTHER DS4000 STORAGE SUBSYSTEM. THERE IS NOT ANY CHECKING FOR THIS RESTRICTION INSIDE THE STORAGE MANAGER CLIENT PROGRAM. 2. The only DS4000 storage subsystems that are supported by the 06.14.xx.xx or higher (06.14.xx.xx, 06.15.xx.xx, 06.16.xx.xx, 06.19.xx.xx or 6.23.xx.xx) controller firmware version are the DS4200 (06.16.88.xx or higher), DS4300 Standard-dual controller or Turbo models (06.19.xx.xx or higher), and the DS4500 (06.19.xx.xx or higher), DS4700 (06.16.4x.xx or higher) and DS4800 (06.14.xx.xx or higher) storage subsystems. Currently, there are not any controller firmware packages version 06.14.xx.xx and higher for other DS4000 storage subsystems. Do not download this controller firmware on any other DS4000 storage subsystems. 3. Always check the README files (especially the Dependencies section) that are packaged together with the firmware files for any required minimum firmware level requirements and the firmware download sequence for the DS4000 drive expansion enclosure ESM, the DS4000 storage subsystem controller and the hard drive firmware. 4. If the managed DS4000 storage subsystem had the FC/SATA intermix premium feature enable, do not upgrade the controller firmware from version 06.10.xx.xx to version 06.12.xx.xx until a FC/SATA intermix premium feature key file is generated and available. Once the controller firmware is upgraded to version 06.12.xx.xx, the FC/SATA intermix premium feature will be shown as out-of-compliance and the FC/SATA intermix premium feature key file is required to re-enable the feature. When the FC/SATA intermix premium feature is in out-of- compliance state, LUNs management functions like creations, deletions and modifications will not be operational. Please refer to the FC/SATA intermix premium feature activation card that was shipped with the FC/SATA intermix premium feature kit for instructions to generate the required premium key file. 5. The DS4700 and DS4800 storage subsystems do not support the attachment of the DS4000 EXP700 drive expansion enclosures. The EXP700 enclosure must be upgraded into DS4000 EXP710 enclosure using the DS4000 EXP700 Models 1RU/1RX Switched-ESM Option Upgrade Kit before it can be attached to the DS4700 and DS4800 storage subsystems. 6. The version 06.16.xx.xx of the DS4700 or DS4800 controller firmware is not compatible with the EXP100 SATA drive expansion enclosures. DO NOT download it into the DS4800 storage subsystems that have EXP100 drive expansion enclosures attached. After the 06.16.xx.xx controller firmware is activated, the DS4800 storage subsystem will not recognize the drives in EXP100 enclosures, causing loss of data availability to the raid arrays and logical drives that are defined in those drives. IBM recommends installing the controller firmware version 6.23.xx.xx and higher in the DS4000 storage subsystems that have EXP100 SATA drive expansion enclosure attached instead. 7. When using STORport miniport version of the Fibre Channel host bus adapter device driver, Windows Server 2003 service pack 1 must be installed along with the Microsoft Windows Server 2003 STORport hot- fix KB916048 - An updated Storport storage driver (version 5.2.3790.2723) is available for Windows Server 2003. The Windows Server 2003 service pack 1 and the STORport hot-fix 916048 are available for download at the Microsoft support web site. 8. The latest version of Microsoft Windows SCSIport and the STORport FC HBA device drivers do not support the BUSCHANGE=0 parameter. It requires the DS4000 storage subsystem controller firmware to be compatible with the MS Plug and Play driver. Not all versions of the DS4000 storage subsystem controller firmware are compatible with the Microsoft Plug and Play driver. Currently, only the controller firmware versions that are listed in the table below for each of the DS4000 subsystems, which support the SCSIport device drivers with BUSCHANGE parameter set to Microsoft required default value of 2, are compatible with the MS Plug-and-Play driver. ------------------------------------------ | DS4000 | Controller Firmware | | Storage Subsystem | Version Required | ------------------------------------------- | DS4700 | 06.16.8x.xx or later| | DS4800 | 06.15.2x.xx | | | 06.16.8x.xx or later| | DS4500 | 06.12.27.xx or later| | DS4400 | 06.12.27.xx or later| | DS4300 | 06.12.27.xx or later| | DS4200 | 06.16.88.xx or later| | DS4100 | 06.12.27.xx or later| ------------------------------------------ Do not use STORport miniport device driver or FAStT/DS4000 FC HBA SCSIport device driver version 9.1.2.11 and higher in the Microsoft Windows servers that have IO access to the DS4000 storage subsystems with controller firmware that are not listed in the controller firmware table above. Please check with your IBM reseller, IBM representative, or the DS4000 interoperability matrix for information on future DS4000 storage subsystems support of this device driver without BUSCHANGE=0 parameter. IBM DS Storage Manager version 10.70 provides full management support for DS4000/DS5000 storage subsystems that have controller firmware version 05.40.xx.xx or higher. ======================================================================= 2.0 Installation and Setup Instructions ----------------------------------------- Note: The web-download Storage Manager version 10.70 host software package must be first unpacked (unzipped) into a user-defined directory. Then, go to this directory, locate the Windows directory to access the Storage Manager version 10.70 host software installer wizard. 2.1 Step-by-step instructions for this code update are as follows ------------------------------------------------------------------ 1. Install and update the device driver for the IBM FAStT, FC-2, FC2-133 single port or dual port, FC 4Gbps PCIx single port or dual port, or Qlogic 4Gb FC PCIe for IBM System X Fibre Channel Host Bus Adapters. a. Install the hardware by using the instructions that come with the adapter. b. Review section 3.2 in this readme file for the minimum recommended device driver version for your Fibre Channel Host Bus Adapters. c. Install the IBM DS4000 Host Adapter device driver by using the instructions provided in the readme.txt file located in either the Host_Adapter directory on this installation CD or from the appropriate driver package that is downloaded from the IBM Support Web site. 2. If there is previous version 7.x, 8.x or 9.10 of the IBM DS4000 storage manager host software installed in the system, you have to uninstall it first before installing the new version of the storage manager host software. IMPORTANT: For servers with boot LUNs in the DS4000 storage subsystems (aka. SAN Boot or Root Boot), a special utility in the RDAC_UninstallUtil_for_BootFromSANConfigurations directory must be run first before Uninstalling the RDAC, especially in the following server configuration - W2K server with DS4000 Storage Manager 8.4 RDAC installed. Please refer to the README in the RDAC_UninstallUtil_for_BootFromSANConfigurations directory for instructions on running the utility. NOTE: This utility can also be used to recover from a failed uninstalling of the RDAC in non-SAN boot Microsoft Windows environments which resulted in a failed reboot of the Windows operating system. For instruction to uninstall the DS4000 storage manager host software, please refer to the IBM System Storage DS Storage Manager Version 10 Installation and Host Support Guide. If the previously installed DS4000 storage manager version is of 10 or later, the DS4000 storage manager host software can be updated with the new code from the installer without the need of uninstalling the existing storage manager host software packages first. Just click "Yes" in the window that the installer displays, stating that there are already installed DS4000 storage manager host software in the server and whether you want to update it with the new code. 3. Install the new storage manager host software from the appropriate CD-ROM directory for your Operating Systems or from the host software package that you downloaded from the IBM Support Web site. Refer to the IBM System Storage DS Storage Manager Version 10 Installation and Host Support Guide for detailed installation instructions. 4. Upgrade the DS4000/DS5000 storage subsystem firmware in the following order - 1. Controller firmware and NVSRAM 2. ESM firmware 3.

ATTENTION: Always check the README files (especially the Dependencies section) that are packaged together with the firmware files for any required minimum firmware level requirements and the firmware download sequence for the DS4000/DS5000 drive expansion enclosure ESM, the DS4000/DS5000 storage subsystem controller and the hard drive firmware. 5. (if applicable) Re-enable the FC/SATA intermix premium feature using the premium key file. Refer to the http://www.ibm.com/systems/support/storage/disk IBM System Storage™ Disk Storage Systems Technical Support web site for the the latest DS Storage Manager host software, the DS4000/DS5000 controllers firmware, the drive expansion enclosure ESM firmware and the hard disk drive code. ======================================================================= 2.2 Refer to the Host_Adapter directory on the installation CD for the applicable drivers. Refer to the http://www.ibm.com/systems/support/storage/disk IBM System Storage™ Disk Storage Systems Technical Support web site for the latest supported host adapters, device drivers, and updated readme. ======================================================================= 2.3 Helpful Hints ------------------ 1. The DS4500 and DS4300 storage subsystem have updated recommended drive-side cabling instructions. The DS4500 instructions are documented in the IBM System Storage DS4500 Installation, Users, and Maintenance Guide (GC27- 2051-00 or IBM P/N 42D3302). The DS4300 instructions are documented in the IBM System Storage DS4300 Installation, Users, and Maintenance Guide (GC26-7722-02 or IBM P/N 42D3300). Please follow the cabling instructions in these publication to cable the new DS4500 and DS4300 setup. If you have an existing DS4500 setup with four drive side minihub installed that was cabled according to the previously recommended cabling instructions, please schedule down time as soon as possible to make changes to the drive side FC cabling. Refer to the IBM System Storage DS4500 and DS4300 Installation, Users, and Maintenance Guide for more information. 2. If you are unable to see the maximum number of drives during Automatic Configuration, you should be able to use Manual Configuration to select individual drives and select the maximum number of drives allowed. 3. Depending on the storage subsystem that you have purchased, you may have to purchase the DS4000 storage partitioning premium feature option or an option to upgrade the number of supported partitions in a storage subsystem. Please see IBM Marketing representatives or IBM resellers for more information. - IBM DS4100 storage subsystem (machine type 1724): The standard and single controller configuration does not have the DS4000 storage partitioning premium enabled. Four partition, eight partition, sixteen and an upgrade from four to eight partition storage partitioning premium feature options can be purchased. - IBM DS4200 storage subsystem (machine type 1814): Depending on the ordering channels, the DS420 storage subsystem is either shipped with 2 storage partitions or with a user selected 2, 4, 8, 16 or 64 storage partitions.

If the subsystem is ordered with less than 512 partitions, various storage partition feature upgrade options can be purchased to increase the maximum number of supported storage partitions. 4. Do not delete the Access LUN or Access Volume. The Access LUN is required by the SMClient to communicate with the storage controllers when using the in-band management method. 5. The DS4000 controller host ports or the Fibre Channel HBA ports can not be connected to a Cisco FC switch ports with "trunking" enable. You might encounter failover and failback problems if you do not change the Cisco FC switch port to "non-trunking" using the following procedure: a. Launch the Cisco FC switch Device Manager GUI. b. Select one or more ports by a single click. c. Right click the port(s) and select Configure, a new window pops up d. Select the "Trunk Config" tab from this window, a new window opens e. In this window under Admin, select the "non-trunk" radio button, it is set to auto by default. f. Refresh the entire fabric. 6. When making serial connections to the DS4000 storage controller, the baud rate is recommended to be set at either 38200 or 57600. Note: Do not make any connections to the DS4000 storage subsystem serial ports unless it is instructed by IBM Support. Incorrect use of the serial port might result in lost of configuration, and possibly, data. 7. All enclosures (including DS4000 storage subsystem with internal drive slots) on any given drive loop/channel should have complete unique ID's, especially the single digit (x1) portion of the ID, assigned to them. For example, in a maximum configured DS4500 storage subsystem, enclosures on one redundant drive loop should be assigned with id's 10-17 and enclosures on the second drive loop should be assigned with id's 20-27. Enclosure id's with the same single digit such as 11, 21 and 31 should not be used on the same drive loop/channel. In addition, for enclosures with mechanical enclosure ID switch like DS4300 storage subsystems, EXP100 or EXP710 storage expansion enclosures, do not use enclosure ID value of 0. The reason is with the physical design and movement of the mechanical enclosure ID switch, it is possible to leave the switch in a “dead zone” between ID numbers, which return an incorrect enclosure ID to the storage management software. The most commonly returned enclosure ID is 0 (zero). In addition to causing the subsystem management software to report incorrect enclosure ID, this behavior also result in enclosure ID conflict error with the storage expansion enclosure or DS4000 storage subsystem intentionally set the ID to 0. The DS4200 and DS4700 storage subsystems and the EXP420 and EXP810 storage expansion enclosures did not have mechanical ID switches. Thus, they are not susceptible to this problem. In addition, these storage subsystems and storage expansion enclosures automatically set the Enclosure IDs. IBM recommendation is not make any changes to these settings unless the automatic enclosure ID settings resulting in non- unique single digit settings for enclosures (including the storage subsystems with internal drive slots) in a given drive loop/channel. 8. The ideal configuration for SATA drives is one drive in each EXP per array, one logical drive per array and one OS disk partition per logical drive. This configuration minimizes the random head movements that increase stress on the SATA drives. As the number of drive locations to which the heads have to move increases, application performance and drive reliability may be impacted. If more logical drives are configured, but not all of them used simultaneously, some of the randomness can be avoided. SATA drives are best used for long sequential reads and writes. 9. IBM recommends at least one hot spare per EXP100 drive expansion enclosure. A total of 15 hot-spares can be defined per DS4000 storage subsystem configuration. 10. Starting with the DS4000 Storage Manager (SM) host software version 9.12 or later, the Storage Manager client script window looks for the files with the file type of ".script" as the possible script command files. In the previous versions of the DS4000 Storage Manager host software, the script window looks for the file type ".scr" instead. (i.e. enableAVT.script for SM 9.12 or later vs. enableAVT.scr for pre-SM 9.12) 11. When you configure a LUN from the DS4000 storage subsystem as a boot device, the system displays a blue screen and does not respond when it is manually or automatically set to hibernate. If you use a LUN in the DS4000 storage subsystem as a boot device for Windows Server 2003, you cannot enable the hibernation feature. To ensure that the hibernation feature is disabled, complete the following steps: a. Select Start >> Settings >> Control Panel >> Power Options. b. Select the Hibernate tab. IMPORTANT: If the Hibernate tab does not appear in this dialog, then your system does not support hibernate. No additional action is required. c. Is the Enable Hibernate Support check box selected? | Yes – Unselect the check box, select Apply, and then go to step d. | No – Go to step d. d. Select the Power Schemes tab. e. From the Turn Off Hard Disks drop-down menu, select Never. f. Select OK. 12. (Windows Server 2003) Cluster resources might fail on a host after rebooting if the "Failback immediately" option is checked in the Microsoft Cluster Server software. With this option checked, you might see failed resources or devices not associated with their preferred node. The current workaround is to make sure that the "Prevent failback" option is checked under Group Properties. This is the default option. Do not use the "Failback immediately" option. 13. (Windows 2000) In a Microsoft Cluster Server (MSCS) environment configured with VERITAS DMP, rebooting a server node owning the resources might take a long time (10 to 15 minutes). It is possible that the long server boot time might cause some Windows delayed write failures. The workaround is to move all the resources from the server node you are planning to reboot to another node before rebooting. 14. (Windows Server 2003) When in a server cluster environment, a failed disk in the storage subsystem does not show as failed in the Cluster Administrator. The host still receives I/O errors, and the disk is shown as failed in the storage management software. This is a known issue with the Windows Server 2003 operating system. Choose one of the following workarounds: • Workaround 1 – Reboot the host that owns the disk resource. The Cluster Administrator should now show the proper state of the disk resource. • Workaround 2 – Change the ownership of the disk resource to a different node in the server cluster configuration. ======================================================================= 3.0 Configuration Information ----------------------------- 3.1 Configuration Settings -------------------------- 1. For the Microsoft Windows servers in MSCS configuration, the IBM DS4000 FC2, FC2-133 single or dual port and FC 4Gbps single or dual port FC HBA adapter "Port Down Retry Count" BIOS parameter must be change to 70 from the default of 30. You can either use the Qlogic SANsurfer (aka. FAStT Management Suite Java (FAStT MSJ)) program or the FC HBA Fast!UTIL program to change the setting in 32bit or X64 64bit servers. To invoke the Fast!UTIL program, perform the following steps: 1. Reboot the server 2. Press when the statement "Press for Fast!UTIL " is displayed when the server scan the FC-133 adapter during boot to get invoke the Fast!UTIL program. 3. If there are multiple FC2-133 HBAs in your server, a list of the HBAs will be displayed. Select the appropriate HBA and press enter to get to the Fast!Util Options menu. Then, select the Configuration Settings menu option followed by Advanced Adapter Settings menu option to display the menu that the Port Down Retry Count parameter is displayed. Select the parameter and press enter to edit the new value. 4. Press ESC twice to get to the "Save setting" menu. Select appropriate option to save the settings and return to the Fast!UTIL Options menu. You can either select another HBA for modification or press ESC and select Reboot System when you are prompted. Alternatively, you can also use the Qlogic SANsurfer program to modify the setting from the Microsoft Windows operating system environment. This is also the recommended method to change NVSRAM setting in Intel Itanium II 64bit (IA64) servers. However, you must reboot the servers for the changes to become effective. In addition, the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Disk registry value must be increased to 120 from the default setting of 60. A utility, SMRegUpdate.reg, is provided in the SMUtil host software package to facilitate this registry change. The QLogic SANsurfer program can be downloaded from the DS4000 System Storage support web site. 2. If a host in a cluster server configuration lost a physical path to a DS4000 storage subsystem controller, the logical drives that are mapped to the cluster group will periodically failover and then failback between cluster nodes until the failed path is restored. This behavior is the result of the automatic logical drive failback feature of the RDAC multipath driver. The cluster node with a failed path to a DS4000 controller will issue a failover command of all logical drives that were mapped to the cluster group to the controller that it can access. After a programmed interval, the nodes that did not have failed path will issue failback command for the logical drives because they can access the logical drives both controllers, resulting in the cluster node with the failed path not be able to access certain logical drives. This cluster node will then issue a failover command for all logical drives, repeating the logical drives failover-failback cycle. The workaround is to disable this automatic failback feature. For Windows, change the DisableLunRebalance registry setting of the [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\rdacdisk\Parameters] registry key from 0 to 3 in each cluster node. Then, reboot each node for the changes to take effect. 3. By default, the IBM DS4000 Storage Manager 8.3 and higher firmware does not automatically map logical drives when the IBM DS4000 storage partitioning premium feature is enabled. This means that the logical drives after being created are not automatically presented to the host systems. a. For a new installation, after creating new arrays and logical drives, create a storage partition with the host type of Windows 2000/Server 2003 non-clustered or Windows 2000/Server 2003 clustered and map the logical drives to this partition. b. If you are upgrading the NVSRAM with Storage Partitions, you may have to change the default host type to match the host system OS. After upgrading the NVSRAM, the default host type is reset to Windows 2000/Server 2003 non-clustered for DS4000 storage subsystem with controller firmware version 06.14.xx.xx or later. For DS4000 storage server with controller firmware version 06.12.xx.xx or earlier, it is reset to Windows non-clustered (SP5 or higher), instead. Refer to the IBM DS4000 Storage Manager online help to learn more about creating storage partitions and changing host types. 4. Running script files for specific configurations. Apply the appropriate scripts to your subsystem based on the instructions you have read in the publications or any instructions in the operating system readme file. A description of each script is shown below. - SameWWN.script: Setup RAID controllers to have the same World Wide Names. The World Wide Names (node) will be the same for each controller pair. The NVSRAM default sets the RAID controllers to have the same World Wide Names. - DifferentWWN.script: Setup RAID controllers to have different World Wide Names. The World Wide Names (node) will be different for each controller pair. The NVSRAM default sets the RAID controllers to have the same World Wide Names. - EnableAVT_W2K_S2003_noncluster.script: The script will enable automatic logical drive transfer (AVT/ADT) for the Windows 2000/Server 2003 non- cluster heterogenous host region. The default setting is to disable AVT for this heterogenous host region. This setting is one of the requirements for setting up the remote boot or SAN-boot. Do not use this script unless it is specifically mentioned in the applicable instructions. (This script can be used for other host type if modifications are made in the script, replacing the Windows 2000/Server 2003 non-cluster host type with the appropriate host type that needs to have AVT/ADT enabled) - DisableAVT_W2K_S2003_noncluster.script: The script will disable the automatic logical drive transfer (AVT) for the Windows 2000/Server 2003 non-cluster heterogenous host region. This script will reset the Windows 2000/Server 2003 non-cluster AVT setting to the default. (This script can be used for other host type if modifications are made in the script, replacing the Windows 2000/Server 2003 non- cluster host type with the appropriate host type that needs to have AVT/ADT disabled) 5. When you are configuring IBM machine type 1722, 1724, 1742, 1814, 1815 or 3552 storage subsystems in host cluster Remote Mirror configurations, contact IBM support for supported host cluster configurations and instructions for configuring IBM storage controllers in clustered Remote Mirror configurations. ======================================================================= 3.2 Hardware status and information ----------------------------------- Up to date interoperability information can be found at: http://www-03.ibm.com/systems/support/storage/config/ssic/ ======================================================================= 3.3 Unsupported configurations ------------------------------ The following lists configurations that are currently not being supported with IBM DS Storage Manager Version 10.70. 1.
