The IBM DS4000 storage subsystem controller firmware version 06.12.23.00 new features and changes are described in the corresponding Change History (*.chg) document. Please refer to this document for more information on firmware modifications. The IBM System Storage DS4000 Storage Manager version 9 Installation and Support Guide for Windows 2000/Server 2003, Netware, ESX Server, and Linux or the IBM System Storage DS4000 Storage Manager version 9 Installation and Support Guide for AIX, HP-UX, Solaris, and Linux on Power are available on IBM's Support Web Site as a downloadable Portable Document Format (PDF) file. In addition, the DS4000 FC/SATA intermix premium features and the DS4000 Copy Services premium features - FlashCopy, VolumeCopy and Enhanced Remote Mirroring - are options purchased separately. The Copy Services premium features require a minimum level of DS4000 midrange disk system controller firmware installed. ------------------------------------------------------------------ | Premium Feature | Required controller firmware version | |--------------------------|---------------------------------------| | FlashCopy | 05.00.04.xx or higher | |--------------------------|---------------------------------------| | VolumeCopy | 05.40.xx.xx or higher | |--------------------------|---------------------------------------| | Enhanced Remote Mirror | 06.10.0x.xx or higher | |------------------------------------------------------------------| | FC/SATA intermix | 06.10.0x.xx or higher | ------------------------------------------------------------------ The DS4000 Storage partitioning premium feature is standard on all IBM DS4000 storage subsystems with the exception of the IBM DS4100 (machine type 1724 with Standard or Single Controller options) and the DS4300 (machine type 1722 with Standard or Single Controller options) storage subsystems. Please contact IBM Marketing representatives or IBM resellers if you want to purchase the IBM DS4000 Storage partitioning premium feature option for it. The Turbo option of the IBM DS4300 is shipped with the IBM DS4000 Storage partitioning premium feature enabled (8 partitions). The DS4000 Storage Controller firmware 06.12.23.00 for this release is available for the IBM machine types 1724-All models (DS4100 with standard/base and single controller option), 1722-60X/60U (DS4300 with Standard/base or Turbo option), 1742-1RX/1RU and 1742-90X/90U (DS4400 and DS4500) only. The DS4000 Storage Controller firmware 06.12.xx.xx for this release is not available for IBM machine types 3542, 3552, or 1722-6LX/6LU (DS4300 with Single controller option). However, the IBM DS4000 Storage Manager 9.12 host software for this release will manage all DS4000 midrange disk subsystem with the controller firmware 04.01.xx.xx or newer (05.xx.xx.xx or newer in Microsoft Windows environments). But, any new features and updates that are introduced in this DS4000 Storage Manager version 9.12 or higher will not be available for any DS4000 midrange disk subsystem controllers without the controller firmware version 06.12.xx.xx installed. Refer to the IBM Support Web Site for the latest Firmware and NVSRAM files and DS4000 Storage Manager host software for the IBM DS4000 midrange disk subsystems. http://www.ibm.com/servers/storage/support/disk/ ======================================================================= 1.1 Limitations --------------------- IMPORTANT: The listed limitations are cumulative. However, they are listed by the DS4000 midrange disk 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. Limitations with version 06.12.16.xx or higher. 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 version 06.12.03.xx. 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. (CMVC 267873) 2. In the configuration that have both SATA-technology drives (EXP100) and Fibre-Channel technology drives (EXP700/EXP710) 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. Limitations with version 06.10.11.xx release 1. In MSCS configurations, the MSCS service must be stopped and set to manual start after server rebooting, the clusdisk driver must have to be set to offline and, then, the server must be rebooted before uninstalling the RDAC driver in the server. If the clusdisk driver is not set to offline and the MSCS service is not set to manual start, the MS cluster service will not start after the new RDAC driver is installed because it can not bring the Quorum disk resource online. The problem is caused by the changing of the disk signatures. The work around is stated in the first sentence of this paragraph. To recover from this problem, you must: 1. Look up the old disk signatures of the disk that are defined as cluster disk resources. They could be found either in the registry under the HKLM/System/CurrentControlSet/Services/Clusdisk/Parameters/Signatures registry key or in the cluster.log file. 2. Look up the new disk signatures of the disks that are defined as cluster disk resources using the dumpcfg utility that is packaged in the Microsoft Windows resource kit. 3. Compare the new and old disk signatures. If new disk signature did not match the old signature, you have to change the new disk signature to the old disk signature values by using the dumpcfg command. The syntax of the command is dumpcfg.exe -s For example, dumpcfg.exe -s 12345678 0 2. Before updating the RDAC driver in a server that is setting up as SAN boot, one of the two Fibre Channel (FC) cables that are connected to the server must be disconnected. The server will bluescreened during the reboot after the un-installation of the RDAC driver if one of the FC cables was not removed. (258127 (82146)) 3. 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 newer. 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 work around is to update the EXP700 ESM firmware to the 9326 or higher version first before upgrading the controller firmware to version 06.1x.xx.xx. (260160 - (82841)) 4. 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 under certain DS4000 storage subsystem reboot scenarios. (261188) Limitations with 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 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 I/Os 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 I/Os 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 spined 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 available. 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 available. 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. Limitations with Storage Manager version 8.4x.xx.xx (and earlier) and DS4000 controller firmware version 05.4x.xx.xx (and earlier) releases 1. Auto LUN/Array Transfer is not enable for IBM AIX and SUN Solaris operating systems. If a controller fails over arrays to the alternate controller and the failed controller is replaced and brought back online, the arrays do not automatically transfer to the preferred controller. This must be done manually by selecting the redistributing arrays menu option in the storage subsystem window of the IBM DS4000 Storage manager client program. 2. You must use the Add/Remove program function in the Control Panel window to uninstall or to disable the IBM DS4000 Storage Manager RDAC device. To re-install the IBM DS4000 Storage Manager RDAC device, follow the instructions in the IBM DS4000 Storage Manager version 9 Installation and Support Guide for Windows 2000/Server 2003, Netware, ESX Server, and Linux. 3. You must always uninstall IBM DS4000 Storage Manager RDAC before you uninstall the Host Bus Adapter driver. Failure to do so may result in system hang or blue-screen condition. 4. 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. 5. When alternately switching back and forth the roles of the logical drives in a remote mirrored relationship, Windows NT4, Windows 2000 and Server 2003 may cache the file(s) on the logical drive(disk) in memory and use these cached data instead of going out to the disk to get the data. This windows OS behavior may make the data look like it was not synchronized between logical drives in a remote mirrored relationship. The fix to the problem is to dismount the primary logical drive in the server before demoting it to secondary role. In Microsoft Windows environment, this is best done by shutting down the server that the primary logical drive is mapped to. Then, promote the secondary logical drive to the primary role and hot_add it to the appropriate server. If the logical drive is of "Dynamic Disk" type, there is a possible solution without requiring server to be shut down. First, in the server that has the primary logical drive, run the SMrepassist program in the DS4000 Storage Manager 8.xx/9.xx util directory with the -f option to flush the cached data to disk. Then, promote the secondary logical drive and hot_add it to the appropriate server. Before promoting the logical drive to primary role in the original server, force a failure to the disk, for example, by running a chkdsk on the disk. Then, promote the logical drive to primary role in the original server and hot_add it. One may have to reactivate the disk after it is hot_added to the server. If the server environment prevents the server from being rebooted and the logical drive is of "basic disk" type, you may use the following steps 1. In the server that has the primary logical drive, run the SMrepassist program in the DS4000 Storage Manager 8.3x util directory with the -f option to flush the cached data to disk. 2. Using the DS4000 Storage Manager to remove the LUN mapping of the logical drive that had the primary role from its server (host computer). 3. Promote the secondary role LUN to the primary role and hot_add it in the appropriate server assuming that the LUN mapping is already defined for this server in the DS4000 storage subsystem. 4. Before promoting the logical drive to primary role in the original server, run Hot_add program or initiate a Scan for Hardware Changes task in the original server. This is to remove the logical drive from the available disks. In W2K, you may see Unsafe Removal of Devices messages. 5. Using the DS4000 Storage Manager to add the LUN mapping of the logical drive that will be promoted to primary role to the original server(host computer). 6. Promote the Logical Drive to Primary role and hot_add it in the original server. If you are unable to hot_add the logical drive or the data still appears to be mismatched, you must reboot the server. 6. When the DS4000 Storage subsystem controller firmware is upgraded from any version 05.00.xx.xx or earlier to version 05.2x.xx.xx or later, all of the Windows 2000 servers that had LUNs mapped in this storage subsystem must be rebooted after the new DS4000 Storage subsystem controller firmware and NVSRAM are successfully applied. The reason is that when the new DS4000 Storage subsystem controller firmware is installed, the controller returns the first four bytes of the firmware revision in the Product Revision field of the SCSI LUN inquiry data. Windows 2000 uses the Product Revision data as part of the LUN identification. So, as the Product Revision data changes due to the new firmware revision level, Windows 2000 thinks that the LUNs with the old Product Revision data were removed from the server. When the 'scan for hardware changes' task is executed by running the DS4000 Storage manager hot_add utility or by selecting the Scan For Hardware Changes menu option of the Devices folder in the Computer Management window, Windows 2000 displays Unsafe Removal of Devices dialogs for these LUNs. The devices in these dialogs are RDAC Virtual Disks and xxxx SCSI devices where xxxx are either 1742, 3552 or 3542 depending on the model type of DS4000 storage subsystem(s) that the Windows 2000 server had LUNs mapped from. The Windows 2000 server will lose connectivity to the LUNs in the DS4000 Storage that has firmware updated. The server must be scanned again for hardware changes. If the logical drives are not added back to the server, one must reboot the server to reconnect to the logical drives. This problem will not occur when upgrading the DS4000 Storage subsystem controller firmware from version 05.20.xx.xx to version 05.3x.xx.xx or later because the product revision data field was fixed at 0520. 7. When the server HBA ports are directly connected to the DS4000 storage subsystem controllers, do not download firmware and NVSRAM files to the controllers with I/Os being generated to the LUNs in the DS4000 storage subsystem. There is no I/Os restriction in SAN Fabric environment i.e. when the HBA port are connected to the DS4000 storage subsystem controller ports via Fibre Channel switches. 8. The supplied SMrepassist utility did not utilize Microsoft Volume Shadow Services APIs to quiesce the LUNs. Appropriate steps are still need to shut down/quiesce the applications like MS Exchange and SQL Server before the FlashCopy logical drive can be made. 9. Uninstalling RDAC may cause Windows Dynamic disks to fail. After the new RDAC is installed and the server is rebooted, these disks must be reactivated and Chkdsk must be run. The work-around is to stop the applications and remove the drive letters or the mount points to these disks before uninstalling and reinstalling RDAC. 10. The current RDAC driver will coexist with Storport model driver as long as it is not the driver for the adapter that talks to the LUNs in the DS4000 Storage subsystems. Note: the current release drivers for all of the Fibre Channel host bus adapters that DS4000 Storage Servers support are based on the SCSIport model. 11. 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. 12. In a direct Fibre Channel connection between the DS4000 Storage subsystem and the HBAs in the host server, the system bluescreen may occur if the DS4000 storage subsystem is powered off. The work around is to power down the server first before powering down the DS4000 storage subsystem. 13. Only logical drives that are configured as "Basic Disks" in the Windows Disk Management folder can have FlashCopy made. The FlashCopy of a logical drive configured as "Dynamic Disk" type will always be failed by the DS4000 storage subsystem when it is added to the host server. 14. There is not an IA-64 version of the DS4000 Management Suite Java (FAStT_MSJ). Use the 32-bit version of the FAStT Management Suite Java for the Windows Server 2003 64-bit edition. However, one should uninstall it once the diagnostic is completed. It could cause the server to bluescreen in heavy I/O loads. 15. Veritas DMP 4.1 is not supported at this time in Windows operating environment. Veritas Volume Manager (DMP) 4.2 is supported with Windows Server 2003 and Windows 2000. 16. 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. 17. 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. 18. When managing a single controller DS4300 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. 19. 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. 20. When you migrating drive Customer Replaceable Units (CRUs) from multiple DS4000 storage subsystems into a single destination DS4000 Storage subsystems, all of the drive CRUs from the same DS4000 storage subsystem should be moved as a ‘set’ into the new destination DS4000 Storage subsystem. 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. 21. 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. 22. 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:. 23. 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. Furthermore, if the EXP100 ESM firmware version is 953x or earlier, no I/Os are allowed during the duration that the EXP100 ESMs are being updated with new firmware, including clustering reservation checking IOs. 24. 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 subsystem 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. 25. 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. 26. Do not perform other storage management tasks, such as creating or deleting logical drives, reconstructing arrays, and so on, while downloading the DS4000 storage subsystem controller firmware and DS4000 EXP ESM firmware. It is recommended that you close all storage management sessions (other than the session that you use to upgrade the firmware) to the DS4000 storage subsystem that you plan to update. 27. Inter-operability with tape devices is supported on separate HBA and switch zones. ======================================================================= 1.2 Enhancements ----------------- IMPORTANT: New features that are introduced with the DS4000 Storage Manager version 9.1x host software will not be available for any DS4000 storage subsystem controllers without the controller firmware version 06.12.xx.xx installed. The DS4000 storage subsystem controller firmware version 6.12.xx.xx is available for the following DS4000 Storage server only - the DS4100 - all models, the DS4300 with Standard or Turbo option, the DS4400 - all models and the DS4500 - all models. Please contact your IBM service representative or IBM resellers for the availability of additional DS4000 storage subsystem models support with controller firmware version 6.12.xx.xx in the future. A summary list of the new features that are introduced with the DS4000 Storage Manager version 9.12 or later host software level in conjunction with the DS4000 storage subsystem controller firmware version 06.12.16.00 or later is as followed: 1. Support 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). 2. Support the DS4100 storage subsystem with Single Controller option 3. When having this controller firmware version 06.12.16.00 or higher installed, the DS4100 is now supported the DS4000 Copy Services Remote Mirroring and VolumeCopy premium features. Please refer to the New Features section of the IBM DS4000 Storage Manager version 9 Installation and Support Guide for the appropriate host server operating system environment for additional information about the IBM DS4000 Storage Manager version 9 enhancements. ======================================================================= 1.3 Prerequisites ------------------ The DS4000 controller firmware and NVSRAM file that are packaged with this README file can ONLY be loaded in the following DS4000 storage subsystems: 1. DS4100 storage subsystems with standard or single controller option 2. DS4300 storage subsystems with Standard or Turbo Option 2. DS4400 storage subsystems 3. DS4500 storage subsystems DO NOT DOWNLOAD this controller firmware on any other DS4000 storage subsystem. There is not any checking for this restriction inside the DS4000 Storage Manager client program. In addition, the procedure to recover the DS4000 storage subsystem that was inadvertently loaded with this firmware file will require downtime to the DS4000 storage subsystem. Also see next section - Dependencies. Note: PRIOR TO DOWNLOADING CONTROLLER FIRMWARE 06.12.23.00 TO THE DS4000 CONTROLLER, THERE IS A PREREQUISTE TO UPGRADE THE STORAGE MANAGER CLIENT TO v9.16. ======================================================================= 1.4 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. 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. 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 RESELLER FOR ASSISTANCE. 3. CURRENTLY, THE ONLY DS4000 STORAGE SUBSYSTEMS THAT ARE SUPPORTED BY THE 06.1X.XX.XX CONTROLLER FIRMWARE VERSION ARE THE DS4100 WITH STANDARD OR SINGLE CONTROLLER OPTION, THE DS4300 WITH STANDARD OR TURBO OPTION, 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 DS4000 STORAGE MANAGER CLIENT PROGRAM VERSION 9.12.XX.XX OR HIGHER MUST BE INSTALLED AND CONFIGURED TO MANAGE YOUR DS4000 STORAGE SUBSYSTEM. THIS PROGRAM IS INCLUDED IN THE APPROPRIATE DS4000 STORAGE MANAGER VERSION 9.12 OR HIGHER HOST SOFTWARE PACKAGES FOR THE OPERATING SYSTEM OF YOUR DS4000 MANAGEMENT STATION. 5. 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. 6. THE DS4000 STORAGE SUBSYSTEM 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 VERSON 06.1X.XX.XX OR LATER. OTHERWISE, THE ERROR 231-FIRMWARE INCOMPATIBLE WILL BE DISPLAYED. 7. PRIOR TO UPGRADING THE DS4000 CONTROLLER FIRMWARE TO VERSION 06.12.23.00, THERE IS A PREREQUISITE TO UPGRADE THE LATEST VERSION OF STORAGE MANAGER CLIENT 9.16. IF THE INCORRECT VERSION OF THE STORAGE MANAGER CLIENT PROGRAM IS USED TO MANAGE THE TO-BE-UPGRADED DS4000 SUBSYSTEM, THE STORAGE MANAGER CLIENT WILL SHOW THAT THE NEW FIRMWARE FILE IS NOT COMPATIBLE WITH THE TO-BE-UPGRADED DS4000 SUBSYSTEM. IBM DS4000 Storage Manager host software version 09.16.xx.xx or later provides full management support for IBM machine types 3552 and 3542 storage controllers that have at least firmware version 04.01.xx.xx (05.xx.xx.xx in Microsoft Windows environment), IBM Machine type 1742-900 and 1742 storage controllers that have at least firmware version 05.00.04.xx, IBM Machine type 1722 storage controllers that have at least firmware version 05.3x.xx.xx, IBM Machine type 1724 storage controllers that have at least firmware version 05.4x.xx.xx or IBM Machine type 1815 storage controllers that have at least firmware version 06.14.xx.xx. The only IBM DS4000 Storage Manager version 09.15.xx.xx supported management function on controllers with non-supported controller firmware versions is controller firmware and NVSRAM download. ======================================================================= 1.5 Code levels at time of release are as follows ------------------------------------------------- Important: The same controller firmware or NVSRAM file can be used for upgrading the controller firmware or NVSRAM through the SMClient GUI or through the controller serial port. Do not attempt to download the firmware or NVSRAM through serial port without the present of IBM Support personnel. A botched controller firmware download via the serial port can cause to the controller to be inoperable. 1. Storage Controller Firmware versions: a. DS4500: FW_06122300_06100600 b. DS4400: FW_06122300_06100600 c. DS4300 Standard: SNAP_288X_06122300 d. DS4300 Turbo : SNAP_288X_06122300 e. DS4100 Standard: SNAP_282X_06122300 f. DS4100 SCU : SNAP_282X_06122300 2. Storage Controller NVSRAM versions: ATTENTION: The DS4000 storage subsystem controller firmware version 06.12.xx.xx uses the FC/SATA intermix premium key file to enable the FC/SATA intermix functionality. It does not rely on a certain version of the NVSRAM file like the controller firmware version 06.10.xx.xx. Do not apply this version 06.12.xx.xx of the firmware until a FC/SATA intermix premium feature key file is generated and available. a. DS4500: N1742F900R912V06 b. DS4400: N1742F700R912V05 c. DS4300 Standard: N1722F600R912V05 (for EXP700/EXP710 ONLY attachment or when FC/SATA intermix premium feature is enabled) d. DS4300 Turbo : N1722F600R912V05 for EXP700/EXP710 ONLY attachment or when FC/SATA intermix premium feature is enabled) e. DS4100 Standard: N1724F100R912V05 f. DS4100 SCU : N1724F10LR912V01 g. DS4300 Standard: N1722F600R28enc2 (for EXP100 ONLY attachment) h. DS4300 Turbo : N1722F600R28enc2 (for EXP100 ONLY attachment) ATTENTION: DO NOT LOAD THIS NVSRAM FILE - N1722F600R18enc2 - ONTO ANY OF THE DS4300 STORAGE SUBSYSTEMS THAT HAVE DRIVES IN THE DS4300 CHASSIS DRIVE SLOTS. THIS WILL CAUSE THE DS4300 storage subsystem NOT RECOGNIZING ANY OF THE DRIVES IN THE DS4300 CHASSIS. THIS COULD RESULT IN THE DEGRADATION OF THE DEFINED RAID ARRAY OR A LOSS OF ACCESS TO DATA. IF THIS NVSRAM FILE IS LOADED INTO A DS4300 storage subsystem WITHOUT ANY DRIVE EXPANSION ENCLOSURES ATTACHED, IT WILL PREVENT THE storage subsystem FROM COMPLETING THE BOOT PROCESS THAT IS INITIATED TO ACTIVATE THE NEW NVSRAM SETTINGS, WHICH MIGHT RESULT IN LOST OF MANAGEMENT ACCESS TO THE DS4300 STORAGE SUBSYSTEM. THERE IS NO SAFETY MECHANISM TO PREVENT THE UNINTENTIONAL LOADING OF THIS NVSRAM FILE. IN ADDITION, DO NOT USE THIS NVSRAM FILE IN THE DS4300 STORAGE SUBSYSTEMS WITH FC/SATA INTERMIX PREMIUM FEATURE ENABLE. Note: The DS4000 storage subsystems that are shipped from the factory will show the NVSRAM version with a "M" prefix instead of the "N" prefixed. Both the "M" prefix and the "N" prefixed NVSRAM versions are the same if the rest of the version information is the same. For example, the N1815D480R915V05 and M1815D480R915V05 NVSRAM versions are the same because both versions share the same "1815D480R915V05" string. The M1815D480R915V05 version was loaded to the DS4800 storage subsystem at the factory. The N1815D480R915V05 version is the one that was posted to the DS4000 support web site for download. Refer to the following IBM System Storage™ Disk Storage Systems Technical Support web site for the latest released code levels. http://www.ibm.com/servers/storage/support/disk/ ======================================================================= 2.0 Installation and Setup Instructions ----------------------------------------- ATTENTION: If you have not already done so, please check the Dependencies section for ANY MINIMUM FIRMWARE REQUIREMENTS for the DS4000 storage server controllers, the drive expansion enclosure ESMs and the hard drives in the DS4000 configurations before upgrading the controller firmware. Make any firmware updates as required BEFORE proceeding to upgrade the DS4000 controller with the firmware and NVSRAM files packaged with this README file. FAILURE to observer the minimum firmware requirement might cause your DS4000 storage subsystem to be OUT-OF-SERVICE. 1. Upgrade the storage manager client program to latest storage manager 9.16 version that is avaible from the ds4000 system storage support web site. Older versions of the storage manager client program will show that the new firmware file is not compatible with the to-be- upgraded DS4000 subsystem, even when the existing version of the controller firmware installed in the DS4000 subsystem is of 6.12.xx.xx code thread. http://www.ibm.com/servers/storage/support/disk/ 2. Updated the firmware of the ESMs in the attached drive expansion enclosures to latest levels before the upgrading the controller firmware. Specifically, if the to-be-updated controller is attached to any EXP700 drive expansion enclosures, the EXP700 ESM firmware must be updated to version 9326 or later before the 06.1x.xx.xx controller firmware is downloaded into the DS4000 storage subsystem controllers. Otherwise, the installed drives in the EXP700 drive expansion enclosures may not be displayed in the DS4000 subsystem management window after the controller firmware is upgraded. In addition, if the ESM firmware of any attached EXP100 drive expansion enclosures must be at version 955x or higher before updating the DS4000 storage subsystem controller firmware to version 06.1x.xx.xx or higher. To download drive expansion ESM firmware, do the following: a. Open the Subsystem Management window. b. Click Advanced => Download => Environmental(ESM) Card Firmware. Follow the online instructions. Note: If the existing controller firmware in the DS4000 storage server is of version 05.30.xx.xx or higher, the drive expansion enclosure ESM firmware can be updated online with no downtime if both ESMs in each of the drive expansion enclosures are functional and one (and ONLY one) drive expansion enclosure is selected in the ESM firmware download window for ESM firmware updating at a time. Note: The latest ESM firmware versions for EXP100, EXP700 and EXP710 drive expansion enclosures are 9563, 9329 and 9631, respectively. 3. If the managed DS4000 storage subsystem with controller firmware version 06.10.xx.xx installed 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, 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. 4. Important: You must install the firmware update prior to downloading the NVSRAM update. Make sure that the firmware and NVSRAM file names match the name listed section 2.4 for your particular DS4000 storage subsystem model. To download firmware, do the following: a. Open the Subsystem Management window. b. Click Storage Subsystem => Download => Firmware. Follow the online instructions. To download NVSRAM, do the following: a. Open the Subsystem Management window. b. Click Storage Subsystem => Download => NVSRAM. Follow the online instructions. 5. (if applicable) Re-enable the FC/SATA intermix premium feature using the premium key file. 6. After the controller firmware and NVSRAM is updated, consider checking the IBM System Storage™ Disk Storage Systems Technical Support web site for the latest released hard drive firmware. To download hard disk drive firmware, do the following: a. Schedule down time because the drive firmware upgrades require that there are no HOST IOs to be sent to the DS4000 controllers. b. Open the Subsystem Management window. c. Click Advanced => Download => Drive Firmware. Follow the online instructions. Note: with controller firmware version 06.1x.xx.xx or later, multiple drives from up to four different drive types can be updated at the same time. ======================================================================= 2.2 Helpful Hints ------------------ 1. 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. 2. Depending on the storage subsystem that you have purchased, you may have to purchase the DS4000 storage partitioning premium feature option or an option to upgrade the number of supported partitions in a storage subsystem. Please see IBM Marketing representatives or IBM resellers for more information. - IBM DS4100 storage subsystem (machine type 1724): The standard and single controller configuration does not have the DS4000 storage partitioning premium enabled. Four partition, eight partition, sixteen and an upgrade from four to eight partition storage partitioning premium feature options can be purchased. - IBM DS4300 storage subsystem (machine type 1722): The standard and single controller configuration does not have the DS4000 storage partitioning premium enabled. Four partition, eight partition, sixteen and an upgrade from four to eight partition storage partitioning premium feature options can be purchased. The IBM DS4300 with Turbo option comes with 8 partition storage partitioning premium option installed. An upgrade to 64 partitions can be purchased for the IBM DS4300 with Turbo option. - IBM DS4400 storage subsystems (machine type 1742 - models 1RU and 1RX): The standard configuration has 64 partitions 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. 3. 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. 4. 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 subsystem FAStT200 (IBM machine type 3542) has only one port per controller. 5. All drive enclosures on any given loop should have complete unique ID's 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. Enclosures ID's 00 ~ 09 should not be used and enclosure ID's with the same single digit such as 11 and 21 should not be used on the same drive loop. 6. 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. 7. 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. 8. 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 9.12 or later vs. enableAVT.scr for pre-9.12) ======================================================================= 3.0 Configuration Information ----------------------------- 3.1 Configuration Settings -------------------------- 1. By default the IBM DS4000 Storage Manager 9.12 firmware does not automatically map logical drives if storage partitioning feature is enabled. This means that the logical drives are not automatically presented to host systems. For a new installation, after creating new arrays and logical drives; a. If your host type is not Windows NT, create a partition with your host type and map the logical drives to this partition. b. If your host type is Windows NT, you can map your logical drives to the "Default Host Group" or create a partition with a NT host type. When upgrading from previous versions of IBM DS4000 Storage Manager to version 9.12. a. If upgrading with no partitions created and you have an operating system other than Windows NT, you will need to create a partition with your host type and map the logical drives from the "Default Host Group" to this partition. b. If upgrading with Storage Partitions and an operating system other than Windows NT is accessing the default host group, you will need to change the default host type. After upgrading, the default host type is reset to Windows NT. Refer to the IBM DS4000 Storage Manager online help to learn more about creating storage partitions and changing host types. 2. When you are configuring IBM machine type 1722, 1742, 3542 or 3552 storage subsystems as boot devices, contact IBM support for supported configurations and instructions for configuring LUNs in the IBM storage subsystems 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.scr: 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.scr: 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.scr: 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.scr: 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_W2K_S2003_noncluster.scr: The script will enable automaticlogical 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.scr: 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) - EnableAVT_Linux.scr: The script will enable automatic logical drive transfer (AVT) for the Linux heterogenous host region. Do not use this script unless it is specifically mentioned in the applicable instructions. - DisableAVT_Linux.scr: The script will disable the automatic logical drive transfer (AVT) for the Linux heterogenous host region. Do not use this script unless it is specifically mentioned in the applicable instructions. - 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, 1742 or 3552 storage controllers in host cluster Remote Mirror configurations, contact IBM support for supported host cluster configurations and instructions for configuring IBM storage controllers in clustered Remote Mirror configurations. ======================================================================= 3.2 Unsupported configurations ------------------------------ The configurations that are currently not being supported with IBM DS4000 controller firmware version 06.12.xx.xx and Storage Manager Version 9.12 or higher are listed below: 1.
