Please contact your IBM service representative or IBM resellers for purchasing information. Important: A problem causing recursive reboots exists while using 7.36.08 and 7.36.12 firmware on IBM System Storage IBM DS 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. IMPORTANT: 1.

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. No new limitations with Storage Manager version 10.86.x5.43 release (controller firmware 07.86.xx.xx) No new limitations with Storage Manager version 10.86.xx05.0035 release (controller firmware 07.86.xx.xx) New limitations with Storage Manager version 10.86.xx05.0028 release (controller firmware 07.86.xx.xx) 1. There is an Unicode character \u2122 (superscript TM) in the EMW-> Help -> About dialog title. This is displayed as ? in HP-UX platform.(LSIP200315879) 2. When using OLH with JAWS screen reader, will have difficulty on navigating through the content in the Index Tab under Help content window due to incorrect and duplicate reading of the text. Please use the search/find tab in the OLH. (LSIP200331090) 3. When using the accessibility software JAWS 11 or 13, may hear the screen reading of a background window, even if the dialog is not in focus. Please use the INSERT+B key to get the reading reinitiated for the dialog in focus.(LSIP200329868) 4. Will not be able to find Tray tab on storage array profile dialog launch. User needs to navigate to Hardware tab to find Tray tab.(LSIP200332950) 5. Will not be able to perform multiple array upgrades having different firmware versions. Please choose to upgrade arrays having different firmware versions separately.(LSIP200335962) 6. May hit IO error if all the paths are lost due delayed uevent, Please always make sure to run 'multipath -v0' command to rediscover the returning path. This will prevent the host from encountering an IO error due to the host losing all paths should the alternate path fails. (LSIP200347725) 7. There may be some confusion when the data is compared between summary tab and storage array profile. There is no actual functionality issue. The way the contents are labelled is not consistent.(LSIP200354832) New limitations with Storage Manager version 10.84.xx.30 release (controller firmware 07.84.xx.xx). 1. On a more than 30 drive disk pool with T10-PI enabled, the reconstruction progress indicator never moves because a finish notification is not sent to Storage Manager. When seeing this issue, just putting the replacement drive in the storage subsystem will allow the reconstruction to resume. (LSIP200298553) No new limitations with Storage Manager version 10.83.xx.23 release (controller firmware 07.83.xx.xx). New limitations with Storage Manager version 10.83.xx.18 release (controller firmware 07.83.xx.xx). 1. A non-T10PI logical drive can not be "volumecopied" to a logical drive with T10 PI functionality enabled. A non-T10 PI logical drive can only be volumeCopied to a non-T10 PI logical drive.(LSIP200263988) 2. Initiating dynamic logical drive expansion (DVE) on logical drives that are part of an asynchronous enhanced remote mirroring (ERM) without write order consistency will result in an error that is misleading because the controller is sending incorrect return code. DVE can only perform on logical drives having asynchronous ERM with write order consistency or synchronous ERM relationship.(LSIP200287980) 3. Cache settings can not be updated on thin logical drives. They can only be updated on the repository drives that are associated with these thin logical drives.(LSIP200288041) 4. Wait at least two minutes after canceling a logical drive creation in the disk pool before deleting any logical drives just created in the disk pool from the cancelled logical drive creation process. (LSIP200294588) 5. T10PI errors were incorrectly reported in the MEL log for T10PI- enabled logical drives that are participated in an enhanced remote mirroring relationship during the logical drive initializations.(LSIP200296754) 6. Having more than 20 SSD drives in a storage subsystem will result in SSD premium feature "Out-of-Compliance" error. One has to remove the extra SSD drives to bring the total number of SSDs in the storage subsystem to 20 or less.(LSIP200165276) 7. Pressing shift + F10 does not display the shortcut or context menu for the active object in the Storage Manger host software windows. The work-around is to use right-click on the mouse or the Windows key on the keyboard. (LSIP200244269) 8. Storage Manager subsystem management window performance might be slow due to Java runtime memory leak. The work around is to close the Storage Manager client program after the management tasks are completed. (LISP200198341) New limitations with Storage Manager version 10.77.xx.28 release (controller firmware 07.77.xx.xx). 1. Only one EXP5060 drive slot with a 3 TB SATA drive inserted can have the ATA translator firmware updated at any one time if the inserted 3 TB drive has "Incompatible" status. Simultaneously updating ATA translator firmware on multiple 3 TB drives having an "Incompatible" status might result in an "interrupted" firmware download state that requires the power- cycling of the subsystem to clear it. This limitation is reduced with the Storage Manager version 10.83 and later. The timeout was increased to accommodate simultaneously updating ATA translator firmware on up to five 3 TB SATA drives having an "Incompatible". 2. The 3 TB NL SAS drive can only be used to create non-T10PI arrays and logical drives. However, in certain conditions, where there are not any available hot-spare drives for T10PI enabled arrays, it will be used by the controller as a hot-spare for a failed drive in these T10PI enabled arrays. The controller will operate properly in this scenario and there are no adverse affects to the system while the 3 TB NL SAS drive is being used as the hot spare in a T10PI enabled array. This limitation is removed with controller firmware version 7.83.xx.xx and later. Please upgrade the controller firmware version 7.83.xx.xx and later if there is need to create a T10 PI-enabled arrays using 3TB NL SAS drives. New limitations with Storage Manager version 10.77.xx.16 release (controller firmware 07.77.xx.xx). 1. When you switch between the Search tab and the TOC tab, the topic that was open in the Search tab is still open in the TOC tab. Any search terms that were highlighted in the Search tab are still highlighted in the TOC tab. This always happens when you switch between the Search tab and the TOC tab. Workaround: Select another topic in the TOC to remove all search term highlighting from all the topics. 2. Support tab in the AMW kept open for longer duration will result in display of unevenly spaced horizontal marks. If the storage Manager is kept open for long durations a few grey lines may be seen on the Support Tab after restoring the AMW. Re-launching the AMW eliminates this problem. 3. Kernel panic while loading RedHat 6.0 on Power PC installation. When trying to load the RHEL6 LoP installation to the system that has existing old OS(LPAR), the system panics. Workaround: For a rack system with an HMC, delete the LPAR and recreate a new one for the installation to work. For a rack system without an HMC and the Power Blade system, the user needs to go to Open Firmware Prompt and type in “dev nvram?and “wipe- nvram? The system will reboot afterward and need to process normal RHEL6 installation. 4. Node unfencing can fail during RHCS startup when automatically generated host keys are used. The cluster manager service (cman) will fail to start, and the user will see the error message “key cannot be zero?in the host log. A user is somewhat likely to hit the issue if the cluster.conf file uses does not have host keys defined manually. If the user forgoes use of SCSI reservation fencing altogether, and relies only on power fencing, they will not experience this issue. Bugzilla 653504 was submitted to RedHat for this issue. 5. RHCS services with GFS2 mounts cannot transfer between nodes when client mounts with NFSv4. When attempting to transfer a cluster service manually, while a client was connected using NFS version 4, the GFS2 mount points failed to unmount. This caused the service to go to the “failed? state. The mount point, along with any other mount points exported from the same virtual IP address, will become inaccessible. Not likely to happen if the user configures the cluster nodes not to allow mount requests from NFS version 4 clients. Red Hat Bugzilla #654333 was opened to discover the root cause and fix the problem 6. The storage subsystem configuration script contains the logical drive creation commands with incorrect T10PI parameter. The workaround is to manually edit the file to change instances of dataAssurance parameters to T10PI. 7. The DS3500 subsysem does not support External Key Management at this time. Please contact IBM resellers or represeantives for such support in the future. Please refer to the file LegacyStorageManagerLimitations-HPUX.chg in the Storage Manager host software download package or in the !Readme CD directory for information on the legacy limitations that might still be applicable for your environment. ======================================================================= 1.3 Enhancements ----------------- The DS Storage Manager version 10.86.x5.43 host software in conjunction with controller firmware version 7.86.32.00 and higher - Provide the following new functions - Add support for DCS3860 (7.86.36.01) - Provide the fixes for the field defects as shown in the changelist file. For more information, please view the IBM System Storage DS Storage Manager Version 10.8 Installation and Host Support Guide and the IBM System Storage DS Storage Manager Version 10 Copy Services User's Guide. IMPORTANT: Do not use Storage Manager host software version 10.77.x5.xx and earlier to manage storage subsystems with 3 TB NL SAS and SATA drive option installed. ======================================================================= 1.4 Level Recommendation and Prerequisites for the update ----------------------------------------------------------- Note: 1. The IBM Storage Manager host software version 10.86 or later for PA-RISC and Intel Itanium II 64bit (IA64) HP-UX 11.31 operating system new features and changes are described in the corresponding Change History document. Please refer to this document for more information on new features and modifications. 2. IBM recommends upgrading to Storage Manager version 10.83.x5.18 or later because it does not include the IBM Support Monitor Profiler code. This code has a security vulnerability that might allow unwanted XSS and SQL injections. If upgrading to Storage Manager version 10.83.x5.18 or later is not possible, one should remove the IBM Support Monitor Profiler code from the management station immediately. The instruction to uninstall IBM Support Monitor Profiler can be found in the IBM System Storage DS Storage Manager Version 10.8 Installation and Host Support Guide. IBM DS Storage Manager version 10.86 for HP-UX was tested heterogeneously on the following HP servers: An HP 9000/800 series server with the following minimum requirements: 1. 440 MHz PA-RISC/IA64 or faster. 2. 1 GB Memory or more 3. 2MB available on /opt. Root (or root-equivalent) privileges for SMutil and SMagent installation. 4. 500MB available disk space on /opt. Root (or root-equivalent) privileges for SMClient installation. 5. For installation in a Java Runtime Environment, at least 500 MB available disk space on /opt and at least 500 MB available on /tmp. Ensure your host is running one of the following operating systems. The storage management software installation program will not verify patches. Some patches might be superseded by other patches. Refer to the Operating System documentation or contact your operating system supplier for more information. 1. HP-UX Version 11.31 (IA64 and PA-RISC2.0) Refer to the IBM System Storage?Interoperation Center (SSIC) web site - http://www.ibm.com/systems/support/storage/ssic/ for information on the latest supported OS, switches and HBA released code levels. 2. For high availability clusters of HP 9000/Series 800 computers, install the HP MC/ServiceGuard 11.18 software package. 3. The IBM DS Storage Manager version 9.12, 9.14 or higher host software installer wizard requires the installation of a graphics adapter in the HP-UX server for it to run. For HP-UX servers without the graphics adapter, you can execute the installer via sh -i console or individual host software installation packages are provided in the SM10.86_HP-UX_Single-10.86.xx05.0035.tgz file. 4. Required installation order for Storage Manager 10.86.xx.xx and controller firmware 07.86.xx.xx: 1. SMruntime - always first 2. SMesm - required by client 3. SMclient 4. SMagent 5. SMutil Note: Steps 1-5 will be done by the SMIA installer if the installation is performed using the SMIA installer. 6. Controller firmware and NVSRAM 7. ESM firmware 8. Drive firmware Code levels at time of release are as follows ----------------------------------------------- The version of the host-software installer wizard for this release is SMIA-HPUX-10.86.xx05.0035.bin. Note: The web-download Storage Manager version 10.86 host software package must be first unpacked (tar -xvz) into a user-defined directory. Then, go to this directory, locate the HP-UX_IA64 directory to access the Storage Manager version host software installation file(s). Starting with the IBM DS storage manager version 9.12, all of the host software packages are included in a single Storage Manager host software installer wizard. During the execution of the wizard, the user will have a choice to install all or only certain software packages depending the need for a given server. There must be at least 990MB of free space in the /opt directory for the installer wizard to install the host software packages. * The DS3000/DS4000/DS5000 Storage Manager host software installer wizard requires the installation of a graphics adapter in the HPUX server for it to run. If you wish to use the wizard but do not have a graphics adapter, you can execute the installer via sh -i console to run in console mode. In addition, there must be at least 990MB of free space in the /opt directory for the installer wizard to install the host software packages. For HPUX servers without the graphics adapter, individual host software installation packages are provided in the SM10.86_HP-UX_Single- 10.86.xx05.0035.tgz file. This installer wizard will install the following version of the host- software packages SMruntime: 10.86.0405.0000 SMclient: 10.86.0G05.0035 SMesm: 10.86.0G05.0007 SMagent: 10.02.0405.0000 SMutil: 10.01.0405.0000 ======================================================================= 1.5 Dependencies ----------------- ATTENTION: 1. The DS5020, DS3950, EXP5000, EXP810, EXP520, and EXP395 FC-SAS drives must have the FC-SAS interposer firmware version 2264 or later installed. Some drives with FC-SAS interposer firmware version earlier than version 2264 may report incorrect inquiry information during Start of Day. This causes the controller firmware to make the drive uncertified (incompatible), which in turn, causes the drive to no longer be accessible for I/Os. This condition will also cause the associated array to go offline. Since the array is no longer accessible, the controller firmware may not recover the cache for all LUNs under this array. This behavior may result in data not being written. If you believe that you have encountered this issue, please call IBM Support for assistance with the recovery actions. The FC-SAS interposer firmware version 2264 and later is available in the ESM/HDD firmware package version 1.78 or later. 2. The 3 TB SATA drive option for EXP5060 expansion enclosure requires ATA firmware version LW1613 and higher. The drive will be shown as "Incompatible" if it is installed in an EXP5060 drive slot with ATA translator firmware version older than LW1613. Please refer to the latest EXP5060 Installation, Users and Maintenance Guide for more information on working with the 3 TB SATA drive option. 3. The Storage Manager host software version 10.83.x5.18 or higher is required for managing storage subsystems with 3 TB NL FC-SAS drives. Storage manager version 10.83.x5.18 or higher in conjunction with controller firmware version 7.83.xx.xx and later allow the creation of T10PI-enabled arrays using 3 TB NL FC-SAS drives. 4. The IBM System Storage IBM DS Controller Firmware Upgrade Tool is required to upgrade any system from 6.xx controller firmware to the 7.xx.xx.xx controller firmware. This tool has been integrated into the Enterprise Management Window of the DS Storage Manager v10.83 Client. 5. 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. IBM DS Storage Manager version 10.86 host software requires the DS3000 /DS4000/DS5000 storage subsystem controller firmware be at version 06.5x.xx.xx or higher. The IBM IBM DS Storage Manager v9.60 supports storage subsystems with controller firmware version 04.xx.xx.xx up to 05.2x.xx.xx. The IBM DS Storage Manager v10.36 supports storage subsystems with controller firmware version 05.3x.xx.xx to 07.36.xx.xx. The IBM DS Storage Manager v10.70 supports storage subsystems with controller firmware version 05.4x.xx.xx to 07.70.xx.xx. ======================================================================= 2.0 Installation and Setup Instructions ----------------------------------------- Note: The web-download Storage Manager version 10.86 host software package must be first unpacked (tar -xvz) into a user-defined directory. Then, go to this directory, locate the HP-UX directory to access the Storage Manager version 10.86 host software installation file(s). 2.1 Step-by-step instructions for this code update are as follows ------------------------------------------------------------------ 1. Install and update the driver for the IBM DS4000 FC Host Bus Adapter. a. Install the hardware by using the instructions that come with the adapter. b. Install the Fibre Channel Host Bus Adapter driver by using the instructions provided with the adapter. 2. Install the new Storage Manager host software. If there is previous version (7.x, 8.x or 9.x) of the IBM DS4000 Storage Manager host software (ie. SMRuntime, SMClient, SMUtil and SMAgent packages) installed in the system, you have to uninstall it first before installing the new version of the storage manager software. Refer to the IBM System Storage DS Storage Manager Version 10 Installation and Host Support Guide for detailed installation instructions. Note: The Storage Manager installer might take up to 5 minutes to display the end user license for machine code (EULA) depending on the Operating System versions. 3. Check to see whether HP-UX LVM mirrored volume functionality is used in the HP-UX server. If it is not used, run the disable_ignoreAVT8192_HPUX.script script in the IBM DS Storage Manager script window to disable the IBM DS storage subsystem ignoring of AVT requests for the HP-UX server specific read pattern of 2 blocks at LBA 8192. Note: To re-enable this IBM DS storage subsystem functionality at a later time, run the enable_ignoreAVT8192_HPUX.script script in the Storage Manager script window. 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 DS3000/DS4000/DS5000 controllers firmware, the drive expansion enclosure ESM firmware and the hard disk drive code. ======================================================================= 2.2 Helpful Hints ------------------ 1. The DS4500 and DS4300 storage subsystems 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 minuhub 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. For partitioning in clusters. The partition must be done on the host group level not on the host level. This will allow all cluster hosts to see the same storage. 3. For HPUX 11.31, native multi-pathing is available in place of PVLinks. The DS storage subsystems now support TPGS. If the VG is composed of persistent names disks, then it uses TPGS, otherwise it is a legacy device with PVLinks. 4. Increasing the I/O Timeout value to 120 seconds may improve the performance of the server. By default the timeout value is set to 30 seconds. The physical value can be changed with the following command: pvchange -t 120 /dev/dsk/cXtYdZ - Where X represents controller - Where Y represents target - Where Z represents controller Also, change the logical volume timeout to 240 seconds: lvchange -t 240 /dev//lvol# 5. 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. 6. Depending on the storage subsystem that you have purchased, you may have to purchase the FAST storage partitioning premium feature option or an option to upgrade the number of supported partitions in a storage subsystem.

The DS4000 controller host ports or the Fibre Channel HBA ports can not be connected to a Cisco FC switch ports with "trunking" enabled. 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 Cicso 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. 8. When making serial connections to the IBM DS storage controller, the baud rate is recommended to be set at either 38400 or 57600. Note: Do not make any connections to the IBM DS storage subsystem serial ports unless instructed by IBM Support. Incorrect use of the serial port might result in loss of configuration and/or loss of data. 9. All enclosures (including IBM DS 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 IBM DS 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. 10. 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. 11. IBM recommends at least one hot spare per EXPxxxx drive expansion enclosure. A total of 15 hot-spares can be defined per IBM DS storage subsystem configuration. 12. Starting with the IBM DS 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 IBM DS 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) ======================================================================= 3.0 Configuration Information ----------------------------- 3.1 Configuration Settings -------------------------- 1. By default, the IBM DS Storage Manager SMClient program does not automatically map logical drives when the IBM DS4000/DS5000 storage partitioning premium feature is enabled. This means that the logical drives after being created are not automatically presented to the host servers. a. For a new installation, after creating new arrays and logical drives, create a storage partition with the host type of HP-UX and map the logical drives to this partition or change the default host type to HP-UX if the Storage Partitioning premium feature is not enable. 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 server 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 DS Storage Manager online help to learn more about creating storage partitions and changing host types. 2. When you are configuring IBM machine type 1722, 1724, 1742, 1814, 1815, 1818, 3542 or 3552 storage controllers as boot devices, contact IBM support for supported configurations and instructions for configuring IBM storage controllers as boot devices. 3. 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: (Do not use this script when the installed storage subsystem controller firmware version is of 7.83.xx.xx and later) 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) - disable_ignoreAVT8192_HPUX.script: This script will disable the DS4000 storage subsystem ignoring of AVT requests for the HP-UX server specific read pattern of 2 blocks at LBA 8192. The AVT ignoring request for the LBA 8192 reads was implemented to prevent a possible occurrence of an AVT storm caused by the HP-UX server probing in the wrong order of available paths to the volume(s) when it detect server to LUN path failure. Use this script only when you do not have defined LVM mirrored volumes using the mapped logical drives from the DS4000 storage subsystems. Please contact IBM support for additional information, if required. - enable_ignoreAVT8192_HPUX.script: This script will enable the DS4000 storage subsystem ignoring of AVT requests for the HP-UX server specific read pattern of 2 blocks at LBA 8192. The AVT ignoring request for the LBA 8192 reads was implemented to prevent a possible occurrence of an AVT storm caused by the HP-UX server probing in the wrong order of available paths to the volume(s) when it detect server to LUN path failure. Use this script only when you do have defined LVM mirrored volumes using the mapped logical drives from the DS4000 storage subsystems. Please contact IBM support for additional information, if required. 4. 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. 5. In the event the worldwide port names (WWPNs) do not show up when defining host ports in the Mapping view of the Subsystem Management window, manually enter the WWPNs. ======================================================================= 3.2 Unsupported configurations ------------------------------- The configurations that are currently not being supported with IBM IBM DS Storage Manager Version 10.8x are listed below: 1.
