Controller firmware 06.16.xx.xx does not support EXP100 storage expansion enclosures. Do not download it into DS4000 storage subsystems that have EXP100 enclosures attached. For the DS4800 storage subsystems with EXP100 enclosures attached, use the controller firmware version 6.15.xx.xx instead. 2. Controller firmware 06.16.4x.xx and higher is required for the DS4700-all models and the DS4800-model 80A/80H. These models do not support older 06.16.xx.xx versions of controller firmware. 3. Controller firmware 06.16.88.xx and higher is required for the DS4200-all models. These models do not support older 06.16.xx.xx versions of controller firmware. 4. Controller firmware 06.19.xx.xx is required for the DS4300- standard-dual controller or Turbo models and the DS4500-all models, for attaching the EXP810 storage expansion enclosures. New features that are introduced with the controller firmware version 06.19.xx.xx or later will not be available for any DS4000 storage subsystem controllers without the controller firmware version 06.19.xx.xx installed. The following table shows the controller firmware versions required for attaching the various models of the DS4000 Storage Expansion Enclosures. --------------------------------------------------------------------- | Controller | EXP Storage Expansion Enclosures | | FW Version |------------------------------------------------------| | | EXP100 | EXP420 | EXP500 | EXP700 | EXP710 | EXP810 | |------------|---------|--------|--------|--------|--------|--------| |5.3x.xx.xx | No | No | Yes | Yes | No | No | |------------|---------|--------|--------|--------|--------|--------| |5.40.xx.xx | No | No | Yes | Yes | No | No | |------------|---------|--------|--------|--------|--------|--------| |5.41.xx.xx | Yes | No | No | No | No | No | |------------|---------|--------|--------|--------|--------|--------| |5.42.xx.xx | Yes | No | No | No | No | No | |------------|---------|--------|--------|--------|--------|--------| |6.00.xx.xx | No | No | No | Yes | Yes | No | |------------|---------|--------|--------|--------|--------|--------| |6.10.xx.xx | No | No | No | Yes | No | No | |------------|---------|--------|--------|--------|--------|--------| |6.12.xx.xx | Yes | No | No | Yes | Yes | No | |------------|---------|--------|--------|--------|--------|--------| |6.14.xx.xx | No | No | No | No | Yes | No | |------------|---------|--------|--------|--------|--------|--------| |6.15.xx.xx | Yes | No | No | No | Yes | No | |------------|---------|--------|--------|--------|--------|--------| |6.16.2x.xx | No | No | No | No | Yes | Yes | |------------|---------|--------|--------|--------|--------|--------| |6.16.8x.xx | No | Yes | No | No | Yes | Yes | |------------|---------|--------|--------|--------|--------|--------| |6.16.9x.xx | No | Yes | No | No | Yes | Yes | |------------|---------|--------|--------|--------|--------|--------| |6.19.xx.xx | Yes | No | No | No | Yes | Yes | --------------------------------------------------------------------- ======================================================================= 1.2 Limitations --------------------- IMPORTANT: The listed limitations are cumulative. However, they are listed by the DS4000 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 Installer (SMIA) package version 09.19.xx.06 release 1. 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 2. 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. 3. 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 substems are connected to EXP810s and EXP100s. In additon, 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. 4. If a DS4000 subsystem undergoes any operation that causes the controller to reset and go through the start-of-day boot process while you are attempting to add hardware, drives, or logical drives associated with the controller, the controller will send alert event notifications to the DS4000 subsystem Major Event Log (MEL) Log. The events indicate that the drives or the logical drives are offline or failed. The event notifications in the MEL Log are expected during the time that the controller is going through a boot process. The workaround is to wait at least 10 minutes after the controller reset is complete before moving logical drives or adding hardware. Use the DS4000 subsystem MEL to verify the time of the last controller reset event. 5. In the DS4300 and DS4500 Installation, User's and Maintenance guides, there are references that might mislead the user into thinking that IBM does not support partially-filled storage expansion enclosures or storage subsystems. IBM does support partially-filled storage expansion enclosures or storage subsystems as long as at least two drives are installed in the storage expansion or subsystem enclosures. However, IBM does not support partially-filled storage expansion enclosures or storage subsystems where the empty slots are required to keep the number of hard drives in the redundant drive loop/channel pair not exceeding the maximum of 112 drives per drive loop/channel. This is to prevent inadvertently inserting drives in those slots causing the controller of getting into the state that might result in lost of access to the storage subsystem. 6. 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. Limitations with Storage Manager Installer (SMIA) package version 09.16.xx.62 release none Limitations with Storage Manager Installer (SMIA) package version 09.16.xx.44 release for the DS4000 controller firmware version 6.12.27.xx and 6.16.8x.xx None Limitations with Storage Manager Installer (SMIA) package version 09.16.xx.09 release for the DS4000 controller firmware version 6.16.24.xx None Limitations with Storage Manager Installer (SMIA) package version 09.16.xx.08 release for the DS4000 controller firmware version 6.16.24.xx 1. Controller firmware 06.16.xx.xx does not support EXP100 storage expansion enclosures. Do not download it into DS4000 storage subsystems that have EXP100 enclosures attached. After the 06.16.xx.xx controller firmware is activated, the DS4000 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. The controller firmware version 6.15.xx.xx and earlier must be installed in the DS4000 storage subsystems that have EXP100 SATA drive expansion enclosure attached instead. 2. The storage subsystem might not recognize the drives or drive expansion enclosure correctly which results in the displaying of error messages or the inability to perform storage subsystem management operations, such as creating logical drives or arrays or initializing arrays from the storage management software. This behavior could be caused by powering up a DS4000 storage subsystem without any drive expansion enclosures attached and then connecting one or more drive expansion enclosures to the storage subsystem after it completes boot process. The workaround is to make sure that the drive expansion enclosure(s) with at least two drives are connected to the DS4000 storage subsystem before you turn on the storage subsystem power. 3. Remove the drive(s) while the storage subsystem is online and then wait until the storage subsystem is going the boot process following a storage subsystem reboot event to reinsert the (new) drive(s) might cause the drives to be marked as failed after the storage subsystem completes the boot process. The workaround is to wait until the storage subsystem is back online before reinserting the drives. If the storage subsystem still does not recognize the drives, reconstruct the drives by using the Advanced -> Recovery -> Reconstruct menu function in the storage subsystem management window. 4. Uninstalling the storage manager host software package might leave the JAVA JRE directory behind. This problem might occur if you uninstall a copy of the SANtricity Storage Manager software that has been upgraded from a previous release. The newer installation package could not delete the JRE directory created with an older installation package. The workaround is to manually delete any directories left behind after uninstalling the software. 5. When creating remote logical drive mirrors through the SMCli script engine in the DS4000 Storage Manager client program, the following error might display during execution, stopping the remote logical drive mirror creation process: Error 173 - The operation cannot complete because the configuration number on the remote storage array is invalid. Some remote logical drive mirrors might have already been created. Rerun only the portion of the script that should be run to finish creating the rest of the remote logical drive mirrors. 6. A JavaScript error might cause the Glossary pop-up window to stay open when the help contents on the storage management software GUI are closed and reopened. Workaround None. This is a SUN JAVA defect. 7. Sometimes when there are two Linux hosts connecting to the same storage subsystem, they are displayed in the Enterprise Management Window as a single node, showing the IP addresses of both Linux hosts rather than displaying them as separate host nodes. As a single node, it is not possible to remove just one of the hosts. The workaround is If the host has a static IP address, then modify the /etc/hosts file to map the host name to the host address. For more information, refer to http://bugs.sun.com/bugdatabase/ view_bug.do?bug_id=4665037. 8. Root Boot fails when QLogic HBA port 1, instead of port 0, is connected to a target during the installation of the operating system. With this hardware setup, the operating system gives you the option to load the Master Boot Record to /dev/sdb. The QLogic HBA driver skips the scan of /dev/sda/. If you accept this option and install the operating system on /dev/sdb, root boot will fail after the operating system is installed. This action occurs because the host will try to scan for the operating system at /dev/sda when it is actually loaded on /dev/sdb instead. The workaround is if QLogic HBA port 1, instead of port 0, is connected to a target when performing a root boot installion the operating system, make sure that the Configure Advanced Boot Loader option box is checked on the Boot Loader Configuration window. Edit the settings in the Change Drive Order window by prioritizing /dev/sdb as the boot device instead of /dev/sda. 9. After you select a file on the firmware download or NVSRAM download dialog, double clicking on “..” in the dialog no longer moves the directory back one level. The workaround is do not select a firmware file until you are finished navigating through your directory structure. 10. (Linux 2.4 Kernel) In Linux, the SCSI device discovery operation scans all contiguous LUNs and stops scanning after a break in the numbers. For example, if LUNs 0, 1, 2, 3, and 7 are being used, 0 through 3 will be scanned and 7 will be skipped. This scenario will cause several problems: • Hosts will not have access to any logical drives associated with skipped LUNs. • SMagent will be stopped at boot time if it does not detect an access logical drive (LUN 31) in the block of contiguous LUNs. • SMdevices will not be able to report on logical drives associated with any skipped LUNs. The workaround is to run hot_add to force the operating system to discover the skipped LUNs. NOTE: The hot_add utility is included with the SANtricity Storage Manager RDAC package for Linux. Limitations with SMIA package version 09.15.xx.06 release for DS4000 controller firmware version 06.12.xx.xx and 06.15.xx.xx release 1. The following error message may be encountered under certain conditions when attempting to create a 2 TB LUN using the Create Logical drive wizard in the Subsystem Management window: "Error 4 - The operation cannot complete because of an incorrect parameter in the command sent to the controller." To avoid this error message, you must take certain steps while using the Create Logical Drive wizard to create a 2 TB LUN. Within the Specify Capacity/Name window within the create logical drive wizard, you must not manually specify the numeric value '2' in the New logical drive capacity field in tandem with the "TB" Units designator. If you do this, the Error 4 message will be issued and you will be unable to create the 2 TB LUN. Click on the up or down arrows next to the input field to select the desire capacity instead. When using the arrows, the program will display the correct maximum logical drive capacity value that can be specified for a given capacity unit (TB, GB, or MB). Limitations with SMIA package version 9.15.xx.xx and DS4000 controller firmware version 06.15.xx.xx release 1. The Red Hat Enterprise Linux 4 operating system cannot load the HBA driver after the kernel is upgraded to a later version. When the Red Hat Enterprise Linux 4 operating system is initially installed, the installation creates a symbolic link to the kernel source tree. When a kernel is upgraded to a later version, the operating system does not create the symbolic link, which prevents the HBA driver from loading. The workaround is to create symbolic links similar to the following: ln -s /usr/src/kernels/2.6.9-5.EL-ia64/ build ln -s build/ source (added 2/10/2006) Limitations with SMIA package version 9.14.xx.05 and DS4000 controller firmware version 06.14.xx.xx release None Limitations with SMIA package version 9.12.xx.08 and DS4000 controller firmware version 06.12.03.xx release 1. Do not cut and paste the information in the DS4000 Storage Manager online help into the DS4000 Storage Manager script command window or into the text file that will be used as input for the SMcli script engine. Extra space may be inserted in the required parameter names which will cause error(s) during the script command execution. (267873) 2. In the configuration that have both SATA-technology drives (EXP100) and Fibre-Channel technology drives (EXP700/EXP710/DS4100) behind the same DS4000 storage subsystem, do not download drives firmware to both SATA-technology drives and Fibre-Channel(FC) technology drives at the same time. Download the drive firmware to drives of a single drive technology (either SATA or FC) at a time. 3. Currently, IBM does not support Gold key Premium Feature as a chargeable upgrade. The Gold key Premium Feature is enable or disable depending on the DS4000 storage subsystem models. 4. The Asynchronous Remote Mirroring utility, asyncRVMUtil, is not supported. This utility is used to automatically synchronize the logical drives in the Remote Mirroring pairs. Please contact IBM representatives or resellers for the support of this utility in the future. 5. The SMclient, SMUtil and SMAgent programs are installed into the /opt/IBM_FAStT directory instead of the /opt/IBM_DS4000 directory. This defect is fixed in the Storage Manager version 9,15 and later releases. 6. Do not add drive expansion enclosure(s) to the DS4000 storage subsystem drive loops/channels during the ESM firmware download. The ESM firmware download process might fail due to a disconnected FC loop. Either add the drive expansion enclosure(s) before initiating the ESM firmware download or wait until the ESM firmware download is completed before adding additional drive expansion enclosures to the drive loop/channel. (added 2/10/2006) 7. Small Form-factor Pluggable (SFP) hardware that is removed and then reinserted within 10 seconds might not be recognized by the controller. Device polling is done at 10-second intervals. Any device that is removed and replaced within the 10-second window will not be recognized. After removing SFP hardware, ALWAYS wait at least 20 seconds before replacing or reinserting it. (added 2/10/2006) 8. When connected through the DS4000 Storage Manager Agent and mapped volumes using Storage Partitioning on an in-band managed storage subsystem, the following error message might appear after a successful volume-to-LUN mapping operation: Error 62 - The operation cannot complete because the logical unit number (LUN) is already in use. Please enter another LUN. Verify that the volume-to-LUN mapping was created correctly. If it was, this error is erroneous and can be ignored. (added 2/10/2006) 9. After you disable a premium feature, the Disable Premium Feature dialog might go blank and no longer show any other enabled premium features to select. The workaround is to close and then re-open the dialog. (added 2/10/2006) 10. When Linux hosts that are configured with QLogic HBA drivers attempt to allocate DMA-capable memory by way of the kernel’s pci_alloc_consistent( ) function, the allocation sometimes fails. There is no workaround. (added 2/10/2006) 11. Linux hosts that are configured with SteelEye® LifeKeeper® cluster version 4.4.3 might lock up due to Error No Memory (ENOMEM) problems. The error messages, located in the /var/log/messages file are displayed as follows: ENOMEM in journal_alloc_journal_head, retrying The workaround is to use only one resource (two LUNs). (added 2/10/2006) Limitations with Storage Manager version 9.10.xx.05 and DS4000 controller firmware version 06.10.11.xx release 1. Do not update the DS4000 storage subsystem controller firmware to version 06.1x.xx.xx from versions 05.4x.xx.xx or earlier if the EXP700 ESM firmware of the attached exp700 was not at 9326 or higher. If the EXP700 ESM firmware is earlier than the 9326 versions, the EXP700 enclosure and the installed drives may not be displayed in the DS4000 subsystem management window after the controller firmware is upgraded to 06.1x.xx.xx version. The workaround is to update the EXP700 ESM firmware to the version 9326 or higher first, before upgrading the controller firmware to version 06.1x.xx.xx. (260160 - 82841) 2. When connecting the EXP100 drive expansion enclosures, one must set the single digit (X1) of the enclosure ID to unique values. This is to prevent the possibility that one of the drives in the EXP100 enclosures be assigned the same ALPA as the DS4000 controller blade under certain DS4000 storage subsystem reboot scenarios. (261188) 3. There are not DS4000 Storage Manager version 9.12 Linux host software packages for AMD-64 or EM64T servers running Linux OS kernels written in native AMD-64 or EM64T code. Please contact IBM resellers or representatives for availability of such support in the future. This limitation was fixed in the DS4000 Storage Manager host software for Linux version 9.15 and later release. 4. In Redhat EL 3.0 Update 3 environment, when there are memory intensive applications running, RHEL 3.0 kernel may not process the memory request from the running device driver processes like network driver or Linux RDAC driver. In certain case, this denial of memory request to the RDAC driver cause it to loop in the memory request routine indefinitely. In that case, the /var/log/messages will be full with the messages like the ones shown below kernel: 493 [RAIDarray.mpp] Cmnd failed-retry 0:0:0 the same path vSCp SN 13633729 TOLO pcmnd SN HOCOTOLO or kernel: 494 [RAIDarray.mpp] Cmnd-failed try alt ctrl 0 vcmnd SN 13799399 TOLO pcmnd SN H1COTOLO The recovery procedure is to reboot the server. (261523) 5. Do not hot swap an HBA in a Linux host while I/O activity is present. If the data path on the to-be-hot swapped HBA is active, place the controller attached to the HBA into service mode to transfer volume ownership to the other controller. Then perform the hot swap of the HBA after the data path is inactive. Limitations with Storage Manager version 9.10.xx.02 and DS4000 controller firmware version 06.10.06.xx release 1. The DS4000 Copy Service RVM is not supported at this time for the DS4100 and the DS4300 storage subsystem with Standard or Single Controller options. (Note: With the release of the controller firmware version 06.12.16.00 or higher, the DS4100 with standard option is now supported Copy Service Remote Mirroring and VolumeCopy premium features.) 2. In the Storage Manager version 9 client Subsystem Management window, the preferred owner of a defined logical drive can not be changed if the logical drive is not managed by the preferred owner/controller. The Storage Manager client will grey-out (not allowing one to select) the controller that is currently managing the logical drive in the selection list of the new preferred owner/controller. One is allowed to only select the controller that is not managing the logical to be the new preferred owner. There is no work-around. 3. Concurrent firmware download (downloading firmware/NVSRAM to the DS4000 storage subsystem controllers with IOs to the host servers) is not supported when upgrading the controller firmware from a 05.xx.xx.xx version to a 06.1x.xx.xx version. ALL IOs must be stopped during the version 06.1x.xx.xx controller firmware upgrade from a 05.xx.xx.xx version. 4. Do not pull or insert drives during the drive firmware download. In addition, ALL IOs must also be stopped during the drive firmware download. Otherwise, drives may be shown as missing, unavailable or failed. 5. Controller diagnostics will not run in a DS4000 storage subsystem with single controller. 6. When instructed to remove and reinsert or to replace a hard drive, wait at least 70 seconds before inserting either the removed existing drive or the new drive into the drive slot. Then, wait up to 3 minutes for the drive to be spun up, recognized by the DS4000 storage subsystem and displayed in the Subsystem Management window before repeating the process for another hard drive. There is no work-around. Similarly, wait at least 70 seconds before reinserting either the removed existing ESM module or the new ESM module into the empty ESM slot in the EXP drive expansion enclosure. Then, wait up to 3 minutes for the ESM CRU to be recognized by the DS4000 storage subsystem and displayed in the Subsystem Management window before repeating the process for another ESM. There is no work-around. 7. Staged firmware and NVSRAM download function is not available on the DS4400 (machine type 1742) models with firmware 06.1x.00.00 in conjunction with IBM Storage Manager 09.1x.xx.xx." 8. The transmission of the User Datagram Protocol (UDP) broadcast message that starts auto discovery may be blocked because of a configuration issue. The storage management software uses UDP at the broadcast IP address 255.255.255.255. The system must be configured to allow broadcast messages for auto discovery to work. The work-around is to manually add storage arrays via their IP address or host name or add the following command to enable the broadcast address on that Ethernet port and allow normal auto discovery to proceed. For example, route add -host 255.255.255.255 eth0 9. The DS4000 Storage Manager client crashes on Linux, AMD-based, 64-bit server because support for the “no execute” bit is enabled by default. To fix the problem, one need to disable support for the "no execute" bit in the operating system by editing the /etc/grub.conf file (if you are using GRUB to boot), and add the following parameter to the end of the kernel line: noexec=off For example, in Red Hat Enterprise Linux AS, you would add noexec=off to the end of the kernel line in the grub.conf file as shown here: kernel /boot/vmlinuz-2.4.21-15.ELsmp ro root=LABEL=/ hdc=ide-scsi noexec=off After adding this information, reboot the server. 10. QLogic Multipath failover driver will not work while the controllers are in service mode because QLogic Multipath failover driver relies on Automatic Logical Drive/Volume Transfer (ADT/AVT) to move the logical drives to the controller that receives the I/O requests. When a controller is in service mode, the controller is not capable of successfully completing the I/O requests. Since the path to that controller is not "broken," QLogic Multipath failover driver has no knowledge to fail over to the alternate controller. The I/O request gets retried repeatedly until the I/O timeout period has been reached and the request times out. IBM recommends the use of Linux RDAC as the DS4000 storage subsystem multipath driver in Linux OS environment. Limitations with Storage Manager version 8.4x.xx.xx (and earlier) and DS4000 controller firmware version 05.4x.xx.xx (and earlier) releases 1. In the DS4000 Storage Manager 9.12 Client, Storage Partitioning must be enabled with the host type of 'linux' selected and the UTM must be removed from the 'Linux' storage partition when the IBM FC HBA failover Linux device driver is used as multipathing (failover/ failback) driver. Otherwise the correct drive information is not presented to the Linux operating system. Note: When using the Linux RDAC as the multipathing driver, the "LNXCL" host type must be used and there is not a requirement that the UTM(Access LUN) must be removed from the LNXCL Storage Partitioning partition. 2. When updating Firmware or NVSRAM with high disk activity a controller may become unresponsive during the update. IBM recommends that disk I/O be stopped during these code updates. 3. When creating a Remote Mirror of a base logical drive, in the case where a FlashCopy of the base logical drive has already been created, the following restriction applies. If the Remote Mirror relationship is created while the base logical drive is receiving I/O, the FlashCopy logical drive will be failed. The work around is to quiesce I/O to the base logical drive while you are creating the remote mirror relationship. Alternatively, if the Remote Mirror relationship is created before creating the FlashCopy logical drive, the FlashCopy logical drive will not be failed. 4. This following behavior applies for the direct Fibre Channel connection setup between the DS4300 storage subsystem host ports and the server HBA ports only. If all DS4300 host ports are occupied, the DS4300 event log may show "host-side data rate negotiation failed" error when the server is booted up, this is normal error that were generated during the host rate negotiation routine inside the DS4300 storage subsystem. 5. When managing the DS4000 storage subsystems with firmware version 05.3x.xx.xx, the Help window of the Subsystem Management window may not be displayed correctly the topics that are listed as result of executing a full text search. 6. The DS4000 storage subsystem when configured with the DS4000 EXP100 SATA Drive Expansion Unit is currently reporting a higher frequency of informational events such as Destination Driver Events (DDEs) and Fibre Channel link up/down events ... in the DS4000 Controller event log compared to the DS4000 storage subsystem configured with Fibre Channel drives. Slower response times of SATA disk drives compared to Fibre Channel disk drives cause higher I/O retries from the DS4000 storage server controllers, resulting in a greater number of informational events logged. In addition, the number of information events reported in the DS4000 storage subsystem event log will also grow in proportion to the increase in I/Os to the Logical Drives. In all cases, the DS4000 storage subsystem controller will always successfully service the timeout I/O on the subsequent retries. 7. When migrating array(s) from a dual controller DS4000 storage subsystem to a single controller DS4000 storage subsystem, you must first set the preferred owner of the to-be-migrated array(s) to be controller A before inserting it into the drive slots of a single controller DS4000 storage subsystem. Otherwise, the array(s) will not be added to the single controller DS4000 storage subsystem correctly which might cause problems. 8. When managing a single controller DS4000 storage subsystem model, do not use the menu option - Configuration->Automatic... - in the Subsystem Management window to create LUNs. You might not be able to access or manage LUNs that are created this way. 9. After you replace a controller with a new controller in the single controller models of DS4000 storage subsystems, the premium features become unauthorized and are out of compliance. Any premium features not supported by the firmware of the new controller are unavailable. The work-around is to upgrade the firmware in the new controller to the same level as the removed controller and re-enable the premium features using the key files that you were provided when the premium feature was originally enabled. 10. When migrating drive Customer Replaceable Units (CRUs) from multiple DS4000 storage subsystems into a single destination DS4000 storage servers, all of the drive CRUs from the same DS4000 storage subsystem should be moved as a ‘set’ into the new destination DS4000 storage server. Before moving the next ‘set’ of drive CRUs, ensure that all of the drive CRUs for a single ‘set’ have been moved to the destination DS4000 storage subsystem. If drive CRUs are not moved as a ‘set’ to the destination DS4000 storage subsystems, the newly relocated array may not appear in the Subsystem Management window. 11. Enclosure IDs may be listed incorrectly in the Subsystem Management window, even if the Enclosure ID switch settings appear to be correct. This is because of the physical design and movement of the Enclosure ID switch, it is possible to leave the switch in a “dead zone” between ID numbers, which will return an incorrect Enclosure ID (this value is 0 in most cases) to the storage management software. When setting the Enclosure ID, ensure that the switch has actuated completely and has settled where the value is clearly visible in the viewing window. 12. To download controller firmware, you must select the drive where the firmware is located. If the drive you select does not respond, the File Selection dialog box will revert to the A: drive and display an error message that drive A: is not ready if there are no media in drive A:. 13. You must suspend all I/O while ESM firmware downloads if you select multiple enclosures for downloading ESM firmware. If you select only one enclosure for download at a time, you can download ESM firmware with I/Os. However, IBM recommends that you suspend all I/O activity to perform firmware upgrades. 14. If the EXP100 ESM firmware version is 953x or earlier, no IOs are allowed during the duration that the EXP100 ESMs are being updated with new firmware, including clustering reservation checking IOs. 15. When saving the DS4000 storage subsystem event log entries, it may take up to several minutes to save all entries in the event log depending on the DS4000 management workstation resources. However, the DS4000 Storage Manager client GUI will show the completion of the event log saving almost instantly. The work around is to check the file size of the file that the event log entries are saved periodically; if the file size does not change, the event log saving is completed. 16. 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 EXP100 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. 17. Inter-operability with tape devices is supported on separate HBA and switch zones. ======================================================================= 1.3 Enhancements --------------------------- The DS4000 Storage Manager version 9.19 host software for Microsoft Windows 2000 and Server 2003 operating systems in conjunction with the DS4000 storage subsystem controller firmware 06.19.18.xx provides support for - Support for attaching the DS4000 EXP810 to the DS4300 Standard-Dual Controller models or Turbo models and the DS4500-All Models.

IBM xSeries and other Intel Itanuim II 64bit based servers with minimum 2048MB of memeory. The servers must have the appropriate version of x86 or x86_64 versions of Linux OS installed. (also see Dependencies section) Code levels at time of release are as follows ------------------------------------------------------------------ IMPORTANT: There are three separate IBM DS4000 Storage Manager host software version 9.19 packages for Linux operating system environments. One host software package is for each of the following Linux operating systems - the 32bit X86 and the 64 bit x86_64 or X64 (AMD64 or EM64T), the Intel Itanium II 64bit and the Linux on Power (LoP). Please use the correct host software package for your Linux operating system environment. Starting with the DS4000 storage manager version 9.16, all of the host software packages (SMruntime, SMclient, SMutil and SMagent) are included in a single DS4000 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. Note: The Linux RDAC package is not part of this installer wizard. It must be installed separately, if needed. For Linux servers without the graphics adapter, individual host software installation packages are provided in the DS4000 Storage Manager Version 9.19 Support for Linux OSes CD under the directory named "/Linux/Individual packages" or "/Linux_IA64/Individual packages". These individual host software installation packages can also be downloaded at the IBM System Storage™ Disk Storage Systems Technical Support web site. - For 32bit Intel architecture (IA-32) servers OR AMD64 and EM64T processor architecture servers having either the x86(IA-32) OR x86_64(64 bit AMD64 and EM64T) versions of Linux OS installed. Note: There is not support for x86_64 version of SuSe SLES 8 Linux OS. The version of the host software installer wizard for this release is SMIA-LINUX-09.19.A5.06.bin. IMPORTANT: The DS4000 Storage Manager host software installer wizard requires the installation of a graphics adapter in the Linux server for it to run. The packages will be installed in the /opt/IBM_DS4000 directory. This installer wizard will install the following version of the host- software packages SMruntime: 09.16.A5.00-1 SMclient: 09.19.G5.06-1 SMutil: 09.16.A5.04-1 SMagent: 09.16.A5.04-1 Note: The SMagent package can be installed when the Linux RDAC is configured as multipath (Failover/Failback) driver. It should not be installed if the IBM FC HBA Linux failover device driver is used as multipath driver. The DS4000 Storage Manger version 9 supports both Linux RDAC and the IBM FC HBA Linux failover device driver as the multipath failover/failback driver for the DS4000 storage subsystem logical drives. When using Linux RDAC driver as the multipath failover/failback driver, the non-failover version of the Linux FC HBA device driver must be installed instead of the failover version. The minimum DS4000 controller firmware version that the Linux RDAC driver supported was 05.4x.xx.xx. You must select one of the two options and refer to the README that are part of the Linux RDAC and the IBM FC HBA Linux failover device driver packages for installation instructions. The latest version of these drivers are as follows: - IBM FC HBA Linux failover device driver: 7.07.61 (for 2.4 kernel) 8.01.06 (for 2.6 kernel) - IBM DS4000 storage subsystem Linux RDAC: 09.00.A5.18 (for 2.4 kernel only) rdac-LINUX-09.00.A5.18-source.tar.gz 09.01.B5.35 (for 2.6 kernel only) rdac-LINUX-09.01.B5.35-source.tar.gz - For Intel architecture 64bit version (IA-64) servers ONLY. These host software packages are not for the AMD64 or EM64T servers that have the native AMD64 or EM64T code version (x86_64) of Linux OS kernel installed. The version of the host software installer wizard for this release is SMIA-LINUX64-09.19.A5.06.bin. IMPORTANT: The DS4000 Storage Manager host software installer wizard requires the installation of a graphics adapter in the Linux server for it to run. The packages will be installed in the /opt/IBM_DS4000 directory. This installer wizard will install the following version of the host- software packages SMruntime: 09.16.A5.00-1 SMclient: 09.19.G5.06-1 SMutil: 09.16.A5.04-1 SMagent: 09.16.A5.04-1 Note: The SMagent package can be installed when the Linux RDAC is configured as multipath (Failover/Failback) driver. It should not be installed if the IBM FC HBA Linux failover device driver is used as multipath driver. The DS4000 Storage Manger version 9 supports both Linux RDAC and the IBM FC HBA Linux failover device driver as the multipath failover failback driver for the DS4000 storage subsystem logical drives. When using Linux RDAC driver as the multipath failover/failback, the non-failover version of the Linux FC HBA device driver must be installed instead of the failover version. The minimum DS4000 controller firmware version that the Linux RDAC driver supported was 05.4x.xx.xx. You must select one of the two options and refer to the README that are part of the Linux RDAC and the IBM FC HBA Linux failover device driver packages for installation instructions. The latest version of these drivers are as follows: - IBM FC HBA Linux failover device driver: 7.07.61 (for 2.4 kernel) 8.01.06 (for 2.6 kernel) - IBM DS4000 storage subsystem Linux RDAC: 09.00.A5.18 (for 2.4 kernel only) rdac-LINUX-09.00.A5.18-source.tar.gz 09.01.B5.35 (for 2.6 kernel only) rdac-LINUX-09.01.B5.35-source.tar.gz Refer to the http://www.ibm.com/servers/storage/support/disk IBM System Storage™ Disk Storage Systems Technical Support web site for the latest released code levels. ======================================================================= 1.5 Dependencies -------------------------- ATTENTION: 1. DS4000 storage subsystem CONTROLLER FIRMWARE VERSION 06.1X.XX.XX REQUIRES THAT THE FIRMWARE VERSION OF AN ATTACHED EXP700 ENVIRONMENTAL SERVICE MODULE (ESM) BE AT VERSION 9326 OR HIGHER. IF THE EXP700 ESM FIRMWARE IS EARLIER THAN THE 9326 VERSIONS, THE EXP700 ENCLOSURE AND THE INSTALLED DRIVES MAY NOT BE DISPLAYED IN THE DS4000 SUBSYSTEM MANAGEMENT WINDOW AFTER THE CONTROLLER FIRMWARE IS UPGRADED. THE CURRENT RELEASE ESM FIRMWARE VERSION FOR THE EXP700 ESM IS 9330. 2. DS4000 STORAGE SUBSYSTEM CONTROLLER FIRMWARE VERSION 06.1X.XX.XX REQUIRES THAT THE FIRMWARE VERSION OF AN ATTACHED EXP100 ENVIRONMENTAL SERVICE MODULE (ESM) BE AT VERSION 955X OR HIGHER. IT IS NOT POSSIBLE TO UPGRADE EXP100 ESM FIRMWARE VERSIONS THROUGH 953X TO VERSION 955X WHEN THE CONTROLLER FIRMWARE IS AT 06.1X.XX.XX. TO DETERMINE THE FIRMWARE LEVEL OF AN EXP100 ESM, IDENTIFY THE PRODUCT LABEL LOCATED AT THE REAR OF THE EXP100 ENCLOSURE. ONLY LABELS ON WHICH THE FIELD REPLACEABLE UNIT (FRU) PART NUMBER READS 25R0156 POSITIVELY INDICATE THAT AN ESM MODULE IS RUNNING FIRMWARE VERSION 955X OR HIGHER. IF THERE IS NO LABEL OR THE PART NUMBER ON THE LABEL DOES NOT READ 25R0156, THE ESM MAY STILL HAVE THE FIRMWARE VERSION 955X OR HIGHER IF IT HAD BEEN PREVIOUSLY UPGRADED. IF NECESSARY, CONTACT YOUR IBM REPRESENTATIVE, SUPPORT, OR RESELLERS FOR ASSISTANCE. IN ADDITION, IT IS NOT POSSIBLE TO UPGRADE THE ESM FIRMWARE FROM VERSION 953X TO VERSION 956X OR LATER DIRECTLY. THE 953X ESM MUST BE UPGRADED TO VERSION 9554 FIRST BEFORE IT CAN BE UPGRADED TO VERSION 956X. 3. 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. 4. The only DS4000 storage subsystems that are supported by the 06.14.xx.xx or higher (06.14.xx.xx, 06.15.xx.xx or 06.16.xx.xx) controller firmware version are the DS4200 (06.16.88.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. 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 drive expansion enclosure ESM, the DS4000 storage subsystem controller and the hard drive firmware. 6. 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. 7. The 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 DS4800 storage subsystems. 8. THE DS4000 STORAGE SERVER WITH CONTROLLER FIRMWARE VERSION 05.41.1X.XX MUST BE UPGRADED TO CONTROLLER FIRMWARE VERSION 05.41.5X.XX FIRST BEFORE IT CAN BE UPGRADED TO CONTROLLER FIRMWARE VERSION 06.1X.XX.XX OR LATER. OTHERWISE, THE ERROR 231-FIRMWARE INCOMPATIBLE WILL BE DISPLAYED. 9. DS4000 storage subsystem controller firmware versions 6.12.16.xx or higher and EXP100 storage expansion enclosure ESM firmware version 9563 or higher are required to provide support for the new 400G SATA drive options and CRUs (P/Ns 39M4570 and 39M4575, respectively) in addition to the new 250G SATA drive CRUs (P/N 40K6837.) This new 250G SATA drive CRU is functionally equivalent to the previously-released CRUs (P/N 90P1349). 10. This version 06.16.xx.xx of the 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. The controller firmware version 6.15.xx.xx and earlier must be installed in the DS4000 storage subsystems that have EXP100 SATA drive expansion enclosure attached instead. 11. Controller firmware 06.16.xx.xx is required to support EXP810 storage expansion enclosures. 12. Controller firmware 06.16.4x.xx and higher is required for the DS4700-all models and the DS4800-model 80A/80H. These models do not support older 06.16.xx.xx versions of controller firmware. The attachment of EXP100 enclosures is not supported for these models. 13. Controller firmware 06.16.88.xx and higher is required for the DS4200-all models. These models do not support older 06.16.xx.xx versions of controller firmware. The attachment of EXP100, EXP710 and EXP810 enclosures is not supported for these DS4200 models. 14. Controller firmware 06.19.xx.xx is required for the DS4300- standard-dual controller or Turbo models and the DS4500-all models, for attaching the EXP810 storage expansion enclosures. IBM DS4000 Storage Manager version 9.19 provides full management support for DS4000 storage subsystems that have controller firmware version 04.01.xx.xx or higher. The only IBM DS4000 Storage Manager version 09.19.xx.xx management function supported on DS4000 storage subsystems with controller firmware version 04.xx.xx.xx up to 04.00.02.xx is controller firmware and NVSRAM download. ======================================================================= 2.0 Installation and Setup Instructions ---------------------------------------------------- Note: The web-download Storage Manager version 9.19 host software package must be first unpacked (tar -xvz) into a user-defined directory. Then, go to this directory, locate the Linux or Linux_IA64 directory to access the Storage Manager version 9.19 host software installation file(s). 2.1 Step-by-step instructions for this code update are as follows ----------------------------------------------------------------------------------------- NOTE: (for installation in Redhat EL AS 3.0 environment only) Some packages of JRE 1.3.1 may not contain all of the files necessary for the IBM DS4000 Storage Manager host software to run correctly on RedHat Enterprise Linux, version 3.0. If you are missing these files, the client and agent software will not run on that system, and an error message similar to the following example may display: /opt/SM8/jre/bin/i386/native_threads/java: error while loading shared libraries: libstdc++-libc6.1-1.so.2: cannot open shared object file: No such file or directory To determine if the required compatibility library is installed, type the following at a terminal window command prompt: "rpm -q compat-libstdc++" The system will respond that the library package is not installed, or display the current version of the package. Verify that the current compatibility library matches the following package version: "compat-libstdc++-7.3.2.96.122" If the library is installed, proceed with the code installation procedure listed below. If not, you can download the library from RedHat Support web site. 1. Install and update the driver for the IBM DS4000 Host Adapter. a. Install the hardware by using the instructions that come with the adapter. b. Install the IBM DS4000 Host Adapter driver by using the instructions provided in the readme file located in the HostAdapter directory on the installation CD or downloaded with the device driver source package from the IBM support web site. c. If one chooses Linux RDAC as multipath failover/failback driver, install the IBM DS4000 Linux RDAC driver by using the instructions provided in the readme file located in the LinuxRDAC directory on the installation CD or downloaded with the device driver source package from the IBM support website. 2. If there is previous version 7.x, 8.x or 9.1x of the IBM DS4000 Storage Manager host software (ie. SMRuntime, SMClient, RDAC, SMUtil and SMAgent packages) installed in the server, you have to uninstall it first before installing the new version of the storage manager host software. 3. Install the new Storage Manager host software version from the CD-ROM directory or from the host software package that you downloaded from the IBM Support Web site. Refer to the IBM DS4000 Storage Manager version 9 Installation and Support Guide for Windows 2000/Server 2003, Netware, ESX Server, and Linux for detailed installation instructions. 4. If the managed DS4000 storage subsystem had the FC/SATA intermix premium feature enable, do not continue with the next step 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 from version 06.10.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. Upgrade the DS4000 storage subsystem firmware in the following order - the drive expansion enclosure ESM code, controller firmware and NVSRAM, and then hard drive firmware code. Refer to the IBM DS4000 Storage Manager version 9 Installation and Support Guide for Windows 2000/Server 2003, Netware, ESX Server, and Linux or the online help in the Subsystem Management window for detailed instructions. CAUTION: 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 server controller and the hard drive firmware. 6. (if applicable) Re-enable the FC/SATA intermix premium feature using the premium key file. Refer to the http://www.ibm.com/servers/storage/support/disk IBM System Storage™ Disk Storage Systems Technical Support web site for the the latest DS4000 Storage Manager host software, the DS4000 controllers firmware, the drive expansion enclosure ESM firmware and the hard disk drive code. ======================================================================= 2.2 Refer to the HostAdapter or LinuxRDAC directory in the installation CD for the applicable drivers or refer to the IBM Support Web Site for the latest supported host adapters, device drivers, and updated readme.

The firmware version for the LP10000/LP10000DC and LP9802/LP9802DC FC Host Bus Adapters will be 1.91a5. ======================================================================= 2.3 Helpful Hints ----------------------- 1. The DS4500 and DS4300 storage subsystem have new 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. 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 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 DS4200 storage subsystem is ordered with less than 64 partitions, various storage partition feature upgrade options can be purchased to increase the maximum number of supported storage partitions. - IBM DS4300 storage subsystem (machine type 1722): The standard 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. The IBM DS4300 Turbo option comes with 8 partition storage partitioning premium option installed. An upgrade to 64 partitions can be purchased for the IBM DS4300 Turbo option. - IBM FAStT200 (machine type 3542: The standard configuration has 16 partition storage partitioning premium option installed. No additional storage partitioning premium feature options can be purchased for these storage subsystems. - IBM FAStT500 and DS4400 storage subsystems (machine type 3552 and 1742 - models 1RU and 1RX, respectively): The standard configuration has 64 partition storage partitioning premium option installed. No additional storage partitioning premium feature options can be purchased for these storage subsystems. - IBM DS4500 storage subsystem (machine type 1742 - models 90X and 90U): The standard configuration has 16 partition storage partitioning premium option installed. An upgrade from 16 to 64 partition storage partitioning premium feature option can be purchased. - IBM DS4700 storage subsystem (machine type 1814): Depending on the ordering channels, the DS4700-model 70 storage subsystem is either shipped with 2 storage partitions or with a user selected 2, 4, 8, 16 or 64 storage partitions. Similarly, the DS4700-model 72 storage subsystem is either shipped with 8 storage partitions or with a user selected 8, 16 or 64 storage partitions. If the DS4700 storage subsystem is ordered with less than 64 partitions, various storage partition feature upgrade options can be purchased to increase the maximum number of supported storage partitions. - IBM DS4800 storage subsystem (machine type 1815): Depending on the ordering channels, the DS4800 storage subsystem is either shipped with 8 storage partitions or with a user selected 8, 16 or 64 storage partitions. If the subsystem is ordered with less than 64 partitions, an upgrade from 8 to 16, 8 to 64 or 16 to 64 partition storage partitioning premium feature option can be purchased. 4. Do not delete the Access LUN or Access Volume if you want to manage the DS4000 storage subsystem in-band (host-agent managed). 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 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. 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. Fabric topology zoning requirement. To avoid possible problem at the host level, it is best practice 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. In addition, this zoning requirement also ensures the maximum number of host connections can be seen and log into the controller FC host port. This is because if a FC HBA port is seen by both controller A and B host ports, it will be counted as two host connections to the storage subsystem - one for controller A port and one for controller B port. Note: The DS4000 storage subsystems DS4500, DS4400 and FAStT500 (IBM machine type 1742 and 3552) have two ports per controller - one per minihub slot. The DS4000 storage subsystems DS4300 (IBM machine type 1722) and DS4100 (IBM machine type 1724) have two ports per controller. The DS4000 storage Server FAStT200 (IBM machine type 3542) has only one port per controller. The DS4800 storage subsystem (IBM machine type 1815) has four ports per controller. 8. 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. 9. 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. 10. 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. 11. 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) ======================================================================= 3.0 Configuration Information ---------------------------------------- 3.1 Configuration Settings ------------------------------------ 1. When using the Linux RDAC as the failover/failback driver, the host type should be set to LNXCL or LNXCLVMWARE instead of Linux. If Linux RDAC is not used, the host type of Linux must be used instead. 2. By default, the IBM DS4000 Storage Manager 9.1x 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, if your host OS type is any of the supported version of Linux OS's, create a partition with the host type of Linux 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 like Linux or LNXCL(LNXCLVMWARE). 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 06.15.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. 3. When you are configuring IBM machine type 1722, 1724, 1742, 3542, 1814, 1815 or 3552 storage controllers as boot devices, contact IBM support for supported configurations and instructions for configuring IBM storage controllers as boot devices. 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. - EnableDriveMigration.script: The Enable drive migration script scans the drives for configurations when they are added to a storage system and will also attempt to use configurations found on the newly added drives. The NVSRAM default will enable drive migration. - DisableDriveMigration.script: The disable drive migration script allows the addition of disk drives while the system is running. In addition, it identifies the drives as unused capacity regardless of past drive configuration. The NVSRAM default will enable drive migration. - EnableAVT_Linux.script: The script will enable automatic logical drive transfer (ADT) for the Linux heterogenous host region. 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 Linux host type with the appropriate host type that needs to have AVT/ADT enabled) - DisableAVT_Linux.script: The script will disable the automatic logical drive transfer (ADT) for the Linux heterogenous host region. 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 Linux 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 clustered Remote Mirror configurations, contact IBM support for supported cluster configurations and instructions for configuring IBM storage controllers in clustered Remote Mirror configurations. 6. When using the Linux RDAC as the multipathing driver, the "LNXCL" host type must be used instead of the linux host type and there is not a requirement that the UTM(Access LUN) must be removed from the LNXCL Storage Partitioning partition. 7. 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 Linux cluster (SteelEye) environments, perform the following steps: a. Open the /etc/mpp.conf file, and change the DisableLunRebalance parameter to 3. Save the changes. b. From a shell prompt, type the following command, and press Enter: mppUpdate c. Reboot the computer for the changes to take effect. d. Repeat this procedure on any system in the cluster configuration that has the Linux RDAC driver installed. ======================================================================= 3.2 Hardware status and information -------------------------------------------------- New installations for IBM Machine types 1722, 1742, 1814, 1815 and 1724 should be installed the following FC Host Bus Adapter (HBA) 1.
