Refer to the IBM TotalStorage Support Web Site for the latest firmware and NVSRAM files for the IBM DS4000 mid-range disk systems. http://www.ibm.com/servers/storage/support/disk/ ================================================================== 1.1 Limitations --------------- New limitations with version 05.42.18.00 controller firmware maintenance releases. 1. Do not cut and paste the information in the DS4000 Storage Manager Version 9 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. (IBM problem record 267873) 2. 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 mid-range disk system models. 3. 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 current and previous maintenance releases. 1. DS4000 Storage Manager prompts you for a password if all hard disk drives are removed from the storage subsystem. After removing all drives from a storage subsystem or if drives do not have power but the controller power is on. The IBM DS4000 Storage Manager will prompt you for a password when trying to start the software or when attempting to perform protected operations. Any password entered will fail. Password information is stored on a reserved area of each hard disk drive on the storage subsystem. Each drive stores a mirrored copy of the password data. When there are no drives in the disk system, the storage management software does not find the password data when you attempt password protected operations. Add one drive to the disk system and retry the operation. If the DS4000 controller unit has power, then turn power off the controller unit. The DS4000 controller unit shall not be powered on until the EXP expansion units are attached and powered on. Properly attach all expansion units (with drives installed), to the DS4000 controller unit and apply power to the EXP. The controller can now be powered on. At this point the mid-range disk system can be re-discovered and managed using the IBM DS4000 Storage Manager. 2. Auto LUN/Array Transfer is not enable for IBM AIX and SUN Solaris operating systems. If arrays failover to an alternate controller and the failed controller is replaced and then brought back online, the arrays do not automatically transfer to the preferred controller. The operation must be done manually by selecting the redistributing arrays menu option in the storage subsystem window of the IBM DS4000 Storage Manager. 3. If you get "Error 21 - The operation cannot complete because a ... is in progress" error when you issue a Subsystem Management command from the IBM DS4000 Storage Manager, the command may be cached. If the command is cached, the IBM DS4000 Storage Manager will run the command as soon as the controller resources are available. Wait for at least ten minutes and check to see whether the command has been run. If not, re-attempt the command. 4. The DS4100 disk system 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 controller major event log compared to a DS4000 mid-range disk system 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 DS4100 controller, resulting in a greater number of informational events logged. The number of information events reported in the system event log will continue to grow in proportion to data transfer to and from the logical drives. In all cases, the DS4100 controller will always successfully service the timeout I/O on the subsequent retries. 5. The DS4000 Copy Service Remote Mirroring and VolumeCopy features are not supported at this time for DS4100 mid-range disk systems. 6. It may take up 12 minutes for the DS4100 to recover after an AC power brown-out event. 7. When connecting DS4000 drive expansion enclosures to the DS4100 mid-range disk system, ensure that the unit digits(x1) of the drive expansion enclosure IDs are set to unique values. Introduced with Version 05.42.06.xx 8. IBM does not support the conversion an existing DS4100 single controller (DS4100 model 1S_) to a DS4100 dual controller DS4100 model 100)and vice versa. Please contact IBM resellers or representatives for support in the future. 9. There is not support for migrating arrays between a DS4100 single controller setup (DS4100 model 1S_) and a DS4100 dual controller setup (DS4100 model 100)and vice versa. Please contact IBM resellers or representatives for such support in the future. 10. There is not support for drive port in the DS4100 single controller CRU. The DS4100 model 1S_ does not support DS4000 EXP100 drive expansion enclosures. Please contact IBM resellers or representatives for such support in the future. 11. In Microsoft cluster, MSCS configurations, the MSCS service must be stopped and set to manual start after server is rebooted. The Clusdisk driver must be set to offline and the Windows 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. The cluster cannot bring the Quorum disk resources online because the disk signature changes caused the problem. The workaround 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 12. In a SAN boot configuration, before updating the Windows RDAC driver in a Windows server, one of the two Fibre Channel (FC) cables that are connected to the server must be disconnected. The Windows server will blue screen during the reboot after the un-installation of the RDAC driver if one of the FC cables is not removed. (IBM problem record 258127) 13. When connecting the EXP100 enclosures, one must set the single digit (X1) of the enclosure ID to unique values. This will prevent the possibility that the controller has the same ALPA as one of the drives in the EXP100 enclosures. This can occur under certain DS4100 controller reboot scenarios. (IBM problem record 261188). ======================================================================= 1.2 Enhancements ---------------- Announced on 11/24/2004 - Support announced for the DS4100 single controller models (1S_). - Increased support for maximum number of EXP100 drive expansion enclosures that can be connected to a DS4100 mid-range disk system. The maximum EXP100 drive enclosures that can be connected to DS4100 is now 7. Previous support was 4 EXP100 drive enclosures. ======================================================================= 1.3 Prerequisites ----------------- - DS4100 mid-range disk systems with controller firmware version 05.42.xx.xx. - DS4000 EXP100 storage expansion enclosures with ESM firmware version 955x or later. ======================================================================= 1.4 Dependencies ----------------- ATTENTION: DS4100 MID-RANGE DISK SYSTEM CONTROLLER FIRMWARE VERSION 05.42.XX.XX REQUIRES THAT THE FIRMWARE VERSION OF AN ATTACHED EXP100 ENVIRONMENTAL SERVICE MODULE (ESM) BE 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. IBM DS4000 Storage Manager Version 8.42 or higher provides full management IBM machine type 1724 (DS4100) storage subsystems that have at least firmware version 05.42.xx.xx. ==================================================================== 2.0 Change History ------------------ ==================================================================== 2.1 Version history.

Open the Subsystem Management window. b. Click Advanced => Download => Drive Firmware. Follow the online instructions. ==================================================================== 3.2 Helpful Hints ----------------- 1. The ideal configuration for SATA drives is one drive in each EXP100 per array, one logical drive per array and one OS disk partition per logical drive. This configuration minimizes the random head movements that increase stress on the SATA drives. As the number of drive locations to which the heads have to move increases, application performance and drive reliability may be impacted. If more logical drives are configured, but not all of them used simultaneously, some of the randomness can be avoided. SATA drives are best used for long sequential reads and writes. 2. IBM recommends 1 hot spare per DS4100 disk system unit or EXP100 drive expansion enclosure. 3. 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. 4. 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 mid-range disk (machine type 1724): The standard (dual controller) configuration does not have the DS4000 storage partitioning premium enabled. Four partition, eight partition, sixteen partition and an upgrade from four to eight partition storage partitioning premium feature options can be purchased. 5. 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 mid-range disk system serial ports unless it is instructed by IBM Support. Incorrect use of the serial port might result in lost of configuration, and possibly, data. 6. SAN 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, the zoning requirement also ensures the maximum number of host connections can be seen and log into the controller FC host port. 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 DS4100 mid-range disk system (IBM machine type 1724) has two ports per controller. 7. Always connect the power supplies of the DS4100 and its drive expansion enclosures to separate power circuits to maximize protection against lost of power. Please refer to the IBM TotalStorage DS4100 Installation, User's and Maintenance Guide for more information and power on and power off sequence requirement for the DS4100. ======================================================================= 4.0 Configuration Information ----------------------------- 4.1 Configuration Settings -------------------------- 1. By default the IBM DS4000 Storage Manager Version 9 client, the controller 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. 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 1724 mid-range disk system as boot devices, contact IBM support for supported configurations and instructions for configuring LUNs as operating system 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 DS4100 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 DS4100 controllers to have different World Wide Names. The World Wide Names (node) will be different for each controller pair. The NVSRAM default sets the DS4100 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 automatic logical drive transfer (AVT/ADT) for the Windows 2000/Server 2003 non-cluster heterogeneous host region. The default setting is to disable AVT for this heterogeneous 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 heterogeneous 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 heterogeneous 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 heterogeneous host region. Do not use this script unless it is specifically mentioned in the applicable instructions. ======================================================================= 4.2 Unsupported configurations ------------------------------ The following lists configurations that are currently not being supported with IBM DS4000 Storage Manager 8.42 or higher. 1.
