IBM System Storage™ DS Storage Manager version 10.70.x5.25 for IBM i. Note: IBM i host attachment to the IBM 1818-all models (DS5300 and DS5100) requires additional purchase of an IBM IBM i Host Kit Option. The IBM IBM i Host Kit options contain the required IBM licensing to attach an IBM i Host System to the DS5100 or DS5300. Please contact your IBM service representative or IBM resellers for purchasing information. The Storage Manager host software for Windows, AIX and Linux on Power are also included in this DVD for the convenient of the users in choosing a computer as the storage subsystem management station. Appropriate host attachment kits must be purchased for Windows, Linux on Power or AIX host attaching to a given storage subsystem. 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.

However, they are listed by DS 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 Installer (SMIA) package version 10.70.x5.10 release (controller firmware 07.70.23.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. Limitations with Storage Manager Installer (SMIA) package version 10.60.x5.17 release (controller firmware 07.60.28.xx). 1. IBM i native attach host kit supports the DS5100 and DS5300 only. The i host attachment must be via native Fibre Channel SAN connection. 2. IBM i maximum LUN capacity is < 2TB and the minimum is 180MB. A maximum of 64 LUNs is allowed per HBA port. 4. All LUNs must be Protected (LUNs defined on RAID 0 arrays are not allowed). 5. Maximum of 300 LUNs from a single DS5300/DS5100 can be added to any ASP at one time. Adding more than 300 LUNs requires additional ASP adds. 6. For VIOS and IBM i native attach customers you must do a data migration when switching LUNs from VIOS environment to the IBM i native attach. There is no support for switching LUN host types from VIOS LUNs to native attach LUNs or native attach LUNs to VIOS LUNs. 7. 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 8. 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. 9. Do not perform other storage management tasks, such as creating or deleting logical drives, reconstructing arrays, and so on, while downloading the DS5300/DS5100 storage subsystem controller firmware and Drive Expansion 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 DS5300/DS5100 storage subsystem that you plan to update. 10. Disabling Cache mirroring while the write-cache is permitted, but not recommended for most environments and applications. Loss of data could occur in the event of a controller failure (data in cache, but not written to disk). Refer to the Installation and Support Guide for further information. 11. Minimum of two IOPless fibre channel adapters are required to support DS5300/DS5100 multipath configuration. Two adapters are required to make a valid multipath configuration with each adapter serving as a path to the same LUNs. 12. LUN 0 being assigned to a Host Group/Host Definition is not supported by IBM i Series. If a situation does occur where a LUN 0 is assigned to a Host Group/Host Definition the user must remove LUN 0 before the IBM i Host Type will appear in the Host Type drop down menus. 13. Copy Services for IBM i native involves special steps, see http://www-03.ibm.com/systems/resources/systems_i_Virtualization_Open_Storage.pdf for additional information. 14. Boot from SAN requires at least one functional active path to boot device (system will not boot from any non-active connection). 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 host software in conjunction with controller firmware version 7.70.23.xx 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. Please refer to the New Features section of the IBM System Storage DS Storage Manager Version 10 Installation and Host Support Guide for additional information about the IBM DS Storage Manager version 10 enhancements. 1.4 Fixes ----------------- 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. 1.5 Level Recommendation and Prerequisites ------------------------------------------------------------ Platform: POWER6 with IBM i IBM Power Systems (POWER6) (rack/tower systems only, no Power Blade support) Required OS Levels: IBM i 6.1 with 6.1.1 LIC refresh If the DS5100/DS5300 is to be used as an IBM i Loadsource, the Power Systems server firmware must be FW3.5.0 or newer.

The IBM i host attachment requires DS5300/DS5100 controller firmware version 07.60.28.xx or higher. ============================================================================== 2.0 Installation and Setup Instructions ------------------------------------------ The IBM System Storage DS Storage Manager version 10 Installation and Host Support Guide is also available on IBM's Support web site as a downloadable Portable Document format (PDF) file. This guide along with the Storage Manager program Online Help provide the installation and support information. ======================================================================= 3.0 Configuration Information and Usage Notes - IBM i Platforms --------------------------------------------------------------- * IBM i supports a maximum of 64 LUNs per port. * For each adapter pair, one HBA must be configured to connect to controller "A" and the other to controller "B". * Storage Partitions and the Default Host Group DS5300/DS5100 offers a premium feature called "Storage Partitioning" which enables users to associate a set of logical drives on a Storage Server that can only be accessed by specified hosts and host ports. This association of logical drives to a set of hosts and host ports is called a Storage Partition. The benefit of defining Storage Partitions is to allow controlled access to the logical drives on the DS5300/DS5100 storage subsystem to only those hosts also defined in the Storage Partition. Without the use of Storage Partitioning, all logical drives appear within what is called the Default Host Group, and they can be accessed by any fibre channel initiator that has access to the DS5300/DS5100 host port. The Default Host Group should not be utilized in IBM i environments. Storage Partitioning should be used when configuring logical drives and hosts. * DS5300/DS5100 subsystem utilizing SATA drives is supported but not recommended due to performance reasons. * Dynamic Volume Expansion (DVE) is not supported on IBM i . * When booting from a DS5300/DS5100 device, both paths to the boot device must be up and operational. * Path fail-over is not supported during the IBM i boot process. Once the IBM i host has booted, fail-over operates normally. * Interoperability with IBM 2107 is supported. * It is highly recommended that Online FW upgrades be scheduled during low I/O loads. * Do not perform other storage management tasks, such as creating or deleting logical drives, reconstructing arrays, and so on, while downloading the storage subsystem controller firmware and 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 DS5300/DS5100 storage subsystem that you plan to update. * The IBM DS Storage Manager Profiler Support Monitor should be setup to run when during times of low I/O. The default is to run at 2 AM every day. If excessive IBM i soft errors are seen at the time of the Profiler executing then Profiler start time or interval should be adjusted to minimize or eliminate soft errors. It is also possible to disabled the monitor to avoid soft errors. 3.1 Helpful Hints ------------------------------- 1. 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. 2. IBM recommends at least one hot spare per EXPxxxx drive expansion enclosure. 3. The DS5300/DS5100 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. 4. Serial connections to the DS5300/DS5100 storage controller must be set to a baud rate of either 38400 or 57600. Do not make any connections to the DS5300/DS5100 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. 5. Do not include the the Access LUN or Access Volume in IBM i. 6. Fabric topology zoning requirement with IBM i To avoid possible problem at the host level, it is required that all Fibre Channel (FC) Switches must be zoned such that a single FC host bus adapter can only access one controller per storage array. 7. It is recommended that to complete the Storage configuration before establishing a connection to or activating a partition for IBM i. If a host logs into the DS5100/DS5300 and there is no configuration defined for the adapter, it will acquire access to all LUNs in the Default Host Group. ======================================================================= 3.2 Configuration settings ------------------------------ 1. By default, the IBM DS Storage Manager Client does not automatically map logical drives when the IBM DS5300/DS5100 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 IBM i 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. Refer to the IBM DS Storage Manager online help to learn more about creating storage partitions and changing host types. ======================================================================= 4.0 Unattended Mode ------------------------ N/A ======================================================================= 5.0 WEB Sites and Support Phone Number -------------------------------------------------------------- 5.1 IBM System Storage™ Disk Storage Systems Technical Support web site: http://www.ibm.com/systems/support/storage/disk 5.2 IBM System Storage™ Marketing Web Site: http://www.ibm.com/systems/support/storage/disk 5.3 IBM System Storage™ Interoperation Center (SSIC) web site: http://www.ibm.com/systems/support/storage/ssic/ 5.4 You can receive hardware service through IBM Services or through your IBM reseller, if your reseller is authorized by IBM to provide warranty service.
