The IBM TotalStorage DS4000 Storage Manager version 9 Installation and Support Guide for Windows 2000/Server 2003, Netware, ESX Server, and Linux or the IBM TotalStorage 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.xx.xx for this release is available for the IBM machine types 1724-100 (DS4100 with standard/base 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, 1724-1SC (DS4100 with Single controller option) 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 06.12.03.xx or higher. 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. 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 with Standard option, the DS4300 with Standard or Turbo option, the DS4400 and the DS4500. 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 host software level in conjunction with the DS4000 storage subsystem controller firmware version 06.12.03.00 is as followed: 1. Support for the FC/SATA intermix premium feature enable via a premium feature key file. A premium key file, instead of a NVSRAM file, is now required to enable the FC/SATA premium feature intermix in a DS4000 storage subsystem. 2. Support for the DS4100 with standard(base) option with controller firmware v06.xx.xx.xx code thread. No new premium features are available at this time for the DS4100 storage subsystem with the controller firmware version 6.12.xx.xx. 3. New DS4000 host-software installation wizard that will automatically install the appropriate host-software components depending on the select server type (i.e.. host or management-station.) 4. Serviceability Enhancement - the ability to extract SMART data for SATA-technology drives. 5. Usability Enhancement - Added Wizard to Storage Manager SMclient to aid users with Storage Partitioning creation with Hosts, Adapters, and mappings. Added Task Assistant to Storage Manager which helps guide users through common task wizards for both the Enterprise and Subsystem management tasks. 6. For HP-UX server configurations with LVM mirrored volume, a fix 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. This fix requires the controller firmware and NVSRAM be at version 06.12.03.00 or later. The fix is to disabling the DS4000 storage subsystem AVT requests for the HP-UX server specific read pattern of 2 blocks (1024 bytes) at LBA 8192. To disable this DS4000 storage subsystem functionality in HP- UX server configurations without LVM mirrored volumes, please refer to the disable_ignoreAVT8192_HPUX.script script described in the 4.1 Configuration Settings section. Please contact IBM support for additional information, if required. 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 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. ======================================================================= 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 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. IBM DS4000 Storage Manager host software version 09.1x.xx.xx 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 or IBM Machine type 1722 storage controllers that have at least firmware version 05.3x.xx.xx. The only IBM DS4000 Storage Manager version 09.1x.xx.xx supported management function on controllers with non-supported controller firmware versions is controller firmware and NVSRAM download. ======================================================================= 2.0 Change History ----------------------------- ====================================================================== 2.1 Version History ----------------------------- This is the latest release of IBM DS4000 TotalStorage™ controller firmware/NVSRAM for the following DS4000 storage subsystem models - the DS4100 with Standard option, the DS4300 with Standard or Turbo options, the DS4400 and the DS4500. Version 06.12.10.00, 09/19/2005 for the DS4100 with Standard option, the DS4300 with Standard or Turbo option, the DS4400, and the DS4500 - 85533 (85265, CMVC 265068, 29644) Problem: Media scan is running only on the even number LUNs. DACstore scrub loops with media scan enabled on one LUN. Fix: To insure scrub flags are cleared, the controller that gets first opportunity to clear the flags will clear all scrub flags. - 90277 (90179, CMVC 275409) Controller lock down due to PCI errors. Fix: Function changes within error handling of PCI SERRs. - 89192 (88852, CMVC 266827) Problem: Mode sense for caching pages (page 8) did not comply with the SCSI-3 specification. Fix: Changed data returned for these commands to conform with the specification by increasing the data from 12 to 20 bytes and initializing the data values appropriately. - 86207 (85917, CMVC 266752) Problem: excessive e-mail notification messages for a single HDD failure. Fix: Break out of loop after posting MEL event so event will not be posted multiple times - 86640 (86452, CMVC 266203) Problem: Storage Manager showing "Needs attention" indicator for an offline drive. No entry in recovery guru for this condition. Fix: Prevent the "needs attention" indication from being set unless the offline drive has at least one piece defined for it. - 87278 (86913, CMVC 270899) Unreadable sectors on logical drive repaired. - 88137 (88091, 88430, CMVC 279189) DS4100 firmware. Problem: excessive printfs recorded for each error on native SATA drives. These printfs can cause timeouts on I/Os issued to SATA drives in EXP100 expansion drawers. Fix: Only call sataDumpCDB and sataDumpRegs if sataIoDebug variable is set. - 86335 (85820, CMVC 267254) MDISK OFFLINE. Problem: Controller is attempting to fail a drive and attempting to suspend volume activity only it can't get the alternate controller to quiesce. The controller will continue forever to attempt to do this until successful. - 88210 Fixed DS4100 NVSRAM FLC bit changing from 0x82 to 0x81 when upgrading from 05.42.x - 88195 (88120) Problem: Controller does not finish SOD. Fix: LockMgr change to role negotiation left lockMgr in an partially uninitialized state. - 89079 Implement lock in cmdRelease to prevent release commands from being processed while reserve commands are blocked. Move the point at which the lock is taken in cmdReserve to a point just above where the lunInfo is initialized. This will prevent stale data if the command is blocked. - 87892 (86968) Fixed a unchecked memory access with multiple drives, controllers and drives being taken off/online. - 87842 Problem: Both controllers reboot during/after an ESM download. Fix: Change timeout with Cache Recover code (vdCacheRecover) hogging the CPU so that the watch dog timer could not be reset. - 86495 (86424) Fixed an error that happens when an integrated GHS drive is replaced by the original spared drive but copyback to the volumes in the volume group is interrupted by a drive spinning down. - 85652 (76791)Prevent potential concurrent volume ownership by two controllers using the DacstoreAccess locking mechanism during SOD. - 88802 Fix loss of drive signing data in NVSRAM on DS4100 ugrade from firmware 05.42 to 06.12. - 86998 Modified the 400GB SATA drive command timeout from 8 seconds to 180 seconds during drive firmware download. - 87335 (87075, 86996) Problem: Downloading drive firmware to a ST3400832AS drive can take longer than the default ATA Download timeout of 30 seconds. For EXP100 expansion drawers the default time allowed for an ATA Pass-Thru Drive Firmware Download is fixed at 30 seconds. If this time is exceeded, the SATA ESM will time out the command and send a COMRESET to the drive, aborting the download. Fix: The APT_TIMEOUT value be changed to 60 seconds for all controllers supporting EXP100 SATA. - 88693 (88617) Problem: Media Scan effectively disabled for volumes at or near 2 Terabytes For RAID 5 volumes or RAID 1 volumes greater than 1 TB. The media scan rate calculation overflows and effectively disables media scan. Fix: Change to use 64 bit math in cfgSetLunScrubRate. - 87782 (87720, 86427) Problem: Ancient I/O (mode select I/O) occuring during stress tests. Fix: Retry lockMgr master/slave negotiation if alternate controller lockMgr had not been initialized. - 85341 (83408) Problem: Ancient I/O error when primary mirrored pair volumes then change its synchronization settings from automatic to manual synchronization. Placed that volume group offline then back online. Fix: Changed task switching logic so that if some task voluntarily offers to preempt, and another task is waiting then preempt that task and allow other tasks to run. - 86078 (85377, Caliber 05514) Implement Ancient I/O NVSRAM programmable thresholds. By supporting (NVSRAM) programmable thresholds, the controller firmware will allow IBM to configure new values that help, in certain circumstances, to reduce the number and frequency of Ancient I/O reboots. This may benefit the upstream host systems in that it should reduce the likelihood of a host-based multi-path driver deciding to trigger fail-over actions due to the temporary inaccessibility of the rebooting controller. - 87551 Problem: DS4500 controller hangs during SOD after being power cycle or reboot. Dirty cache was not able to be recovered properly, causing the controllers to hang during SOD. Fix: Problem was resolved by using a new variable for the local RCB instead of reusing the variable for the global RCB. - 85069 (84406) Change for DS4300 to minimize, as much as possible, the amount of CPU data cache thrashing that occurs when accessing data structures in the I/O path. - 85541 (82793) Problem: Battery age is not updated when reading the profile from the Storage Manager interface. Fix: Force update of cfgGenerationNumber at least daily in pollBattGNT so battery age will be updated at least daily. - 87026 (86609) Problem: Controller PANIC when inserting a drive that contains invalid volume number. Fix: Only call legacyVolumePresentEvent for valid volumes in cfgCreateEventsOnFirstDriveIns to avoid panic in evfWWN.h code for invalid volume number. - 85909 Storage Manager GUI loses communication with array - 85976 (80904) Problem: Unresponsive array from excessive MEL tasks. Fix: Change to not log MEL entries for destination driver errors or drive check conditions that are reported for the same channel in a 2 second window. Record channel number in origin field of destination driver MEL event. - 86166 (86138, 75746) Problem: Ancient I/O (mode select I/O) during stress I/O tests. Fix: Retry lockMgr master/slave negotiation if alternate controller lockMgr had not been initialized. - 86285 Problem: DS4100 controllers were manufactured with incorrect Gold Key NVSRAM setting. Fix: Read FLC during boot; if the value is 0x82 and the inquiry string indicates either non-IBM OEM setting and the controller is DS4100 then the appropriate default setting will be applied (i.e. 0x81). - 86391 Added "special" cases of OEMs for which the NVSRAM Feature Licensing Control byte in NVSRAM may need to be modified. - 88171 (84580) Problem: When running RLS diagnostics on the Storage Manager client, if an ESM's preferred path and current path usage differ, the ESM's physical location is reported under the wrong channel in the dialog. This was the result of logic that would compare the path used to retrieve RLS statistics against the current path used by the driver to communicate with the ESM and change it to the alternate value if they were not the same. Fix: Substituted a call to ssmFindESMPort to determine the correct slot location for the ESM in a given enclosure. - 88369 (88368, 81853) Problem: Client shows RLS negative numbers or RLS data from the device displays the entire history for that device, resulting in very large numbers. RLS request issued to a device will not be able to retrieve valid statistics. Fix: Checks were added to hddRlsCopy to prevent it from copying a timestamp to the RLS storage space. This effectively invalidates the data for that RLS pass and causes another RLS request to be sent. - 87067 (84954) Problem: Profile displays erroneous volume configuration by incorrectly displaying which drives belong to a volume. Fix: Configuration management, the only resolution mechanism available is to reduce the size of the window in which incomplete information could be returned. Change the return value by setting a NULL Object Bundle pointer on a getObjectGraph request received while a global variable maintained by the HLM module indicating that SOD is in progress is TRUE. - 85320 (81081, Caliber 05358) Fix for when an SFP is removed from the system, the entire SFP object that represents the SFP FRU/slot is dropped from the object bundle. - 86045 (81853) Problem: RLS shows negative numbers. RLS from the GUI showed most of the drives as having large negative values for all fields. The others were 0. Fix: If the data in LinkMonitor is invalidated, return null values to the user call. - 86191 (86013) Problem: GHS drive may be dropped from the GHS list. Fix: Changed cfgAddDacstore call such that we don't lose track of the fact that a drive is a hot spare. - 90953 Fix: Ancient I/O during I/O and sysReboot stress test - 89371 Cannot change Secondary to Primary RVM - 89480 (88825) 18GB unexpected free capacity appears in volume group - 89814 IO device error or data corruption on DS4100 - 89094 Loss of communication when creating max volumes on DS4400 - 89139 Alternate controller held in reset during 400GB drive firmware - 89140 Only one pair of ESMs is reported in the RLS data - 89207 sysReboot on DS4400 controllers with 1016 volumes takes 7 min - 87319 (86537, Caliber 05221) Preferred path event optional - 88159 Controller reboots during new database migration processing - 88294 New database processing fails after Controller B reboots Controller A - 88483 Unable to delete RVM in FW version 06.12.03.12 - 88430 Upgraded 06.12.05 FW and two drives failed in 1hr - 79636 New Database: cache is no longer configured on controller A - 85242 Inserting bad SATA drive in DS4100 causes controller reboot - 86260 (Caliber 05586) Can not migrate iSATA tray to diskless 2882 - 87970 ACS from 05.30.x to 06.12.x bricks controller - 83786 No visual indication of ACS on controller FRU LEDs with 06.1x.xx firmware - 84496 BW Build does not compile in the BOU database - 87526 (85593, 83786)No visual indication of ACS on controller FRU LEDs with 06.1x.xx firmware - 87569 Controller firmware does not allow I/O access to initiator that was removed. - 87661 (86919) Timeout should be increased for the ICON messages - 84843 FC Genric Services Register Platform info appears byte swapped - 85958 (85799) Lost communication with the array - 87139 (85938 Intent Log Deadlock - 87229 (86949) Determine correct parameter data from NVSRAM option - 87398 "password" allows access to serial port - 86106 (81081, Caliber 05358)SFP removals are inconsistent - 86251 Skip bcmSetDiscreteLine calls in mhmLoopDiag for SATA drives in DS4100 - 86483 Clone forward 74568 - 86516 (86138, 75746) Ancient I/O - 86862 (86678) Attempting to set both controllers in Service - 86875 (84606) Injecting fault during firmware activation - 87014 (86811) Controller pair AN04 message - 85128 (85091, 83767) Inserting foreign controller with firmware 06.10 - 85187 (85072) Cannot transition from CSM -> Offline - 85257 (83408) Fixed suspend-resume problem - 85363 06.12.xx AMW does not report correct number of Drive channels - 85401 (81980) RAID 5 auto config fails to create volume groups - 85409 Invalid cache reclaim state - 85479 (84906) memory fault from mhmI2cRequestHandle access - 85735 (84886) Read Capacity command returns the new capacity - 85750 (85456) Data corruption after large RAID 5 Volume Group with 2 LUNs - 85770 (85431) Global Hot Spares did not migrate - 85843 Provide a debug function to print out the number of outstanding fail drives. - 85859 (83021) Dependency/race condition in makefile - 85918 (82780) Dead/offline RAID 1 volume could not be recovered - 86194 (84965) Controller panic/exception - 86198 (82668) Controller Volume group - 86450 (86448, 86441) Compilation errors due to change in NVS - 86464 ApplWare build broken - C++ style comments Version 06.12.03.xx, 6/6/2005 for the DS4100 with Standard option, the DS4300 with Standard or Turbo option, the DS4400, and the DS4500 - Rerelease of the 06.12.03.xx firmware package with a new version of the DS4100 storage subsystem controller firmware (version 06.12.03.02) that fixes the "drive not certified" errors or the displaying of "Gold key - Out of Compliance" or "Gold Key - Mismatched Settings" errors after upgrading from 05.42.xx.xx to 06.12.xx.xx.

Storage Controller Firmware versions: a. DS4500: FW_06121000_06100500 b. DS4400: FW_06121000_06100500 c. DS4300 Standard: SNAP_288X_06121000 d. DS4300 Turbo : SNAP_288X_06121000 e. DS4100 Standard: SNAP_282X_06121000 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. DS4300 Standard: N1722F600R28enc2 (for EXP100 ONLY attachment) g. 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. Refer to the following IBM TotalStorage™ Disk Storage Systems Technical Support web site for the latest released code levels. http://www.ibm.com/servers/storage/support/disk/ ======================================================================= 3.0 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. 3.1 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 9554, 9328 and 9631, respectively. 3.2 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. 3.3 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. 3.4 (if applicable) Re-enable the FC/SATA intermix premium feature using the premium key file. 3.5 After the controller firmware and NVSRAM is updated, consider checking the IBM TotalStorage™ 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. ======================================================================= 3.2 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) ======================================================================= 4.0 Configuration Information ----------------------------- 4.1 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. ======================================================================= 4.2 Unsupported configurations ------------------------------ The following lists configurations that are currently not being supported with IBM DS4000 Storage Manager 9.12. 1.
