This guide along with the DS4000 Storage Manager program Online Help provides the installation and support information. Because the version of the controller firmware that will be installed in your DS4100 storage server is of 05.42.xx.xx, you may also want to refer to the IBM TotalStorage™ FAStT Storage Manager version 8.4x Installation and Support Guide for Intel-based Operating System Environments or the IBM TotalStorage FAStT Storage Manager version 8.4x Installation and Support Guide for AIX, HP-UX and Solaris for information that are unique to DS4000 storage manager host software when managing DS4000 storage server with controller firmware version 05.4x.xx.xx. The DS4100 storage server - machine type 1724 model 100, support IBM DS4000 Copy Services premium features FlashCopy only. It does not support the DS4000 Copy Services premium features VolumeCopy and Remote Mirroring at this time. Please contact your IBM representatives or resellers for availability date of support. The DS4000 storage partitioning premium feature is not standard on IBM DS4100 Storage Server. Please contact IBM Marketing representatives or IBM resellers if you want to purchase the IBM DS4000 storage partitioning premium feature option for it. The IBM DS4000 Storage Manager host software version 9.1 is shipped with IBM DS4100 Storage Server. The host software component of IBM DS4000 Storage Manager 9.1 will manage all DS4000 storage server with the controller firmware 04.01.xx.xx or newer. Refer to the IBM Support Web Site for the latest Firmware and NVSRAM files for the IBM DS4000 Storage Subsystems. http://www.ibm.com/servers/storage/support/disk/ ======================================================================= 1.1 Limitations --------------------- 1. 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 not powering on drives and only the controller), the IBM DS4000 Storage Manager software will prompt you for a password when trying to start the software or trying 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 storage subsystem, the storage management software does not find the password data when you attempt password protected operations. Add one drive to the storage subsystem and retry the operation. Since the RAID controller unit should not be powered on until the expansion units are attached and powered on, this should be done by powering off the RAID controller unit, properly attaching all expansion units (with drives installed), to the RAID controller unit and powering them on, and then powering the RAID controller unit back on. At this point the storage subsystems can be re-discovered and managed using the IBM DS4000 Storage Manager 8.2 software. 2. Auto LUN/Array Transfer is not enable for IBM AIX and SUN Solaris OS's. 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. 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 Client, the command may be cached. If the command is cached, the IBM DS4000 Storage Manager Client 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 DS4000 Storage Manager version 8.42 does not support Veritas DMP in Windows operating system environment. Please contact IBM representatives or resellers for the availability of support. 5. The DS4000 storage server 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 server configured with Fibre Channel drives. Slower response times of SATA disk drives compared to Fibre Channel disk drives cause higher I/O retries from the DS4000 storage server controllers, resulting in a greater number of informational events logged. In addition, the number of information events reported in the DS4000 storage server event log will also grow in proportion to the increase in I/Os to the Logical Drives. In all cases, the DS4000 Storage Server controller will always successfully service the timeout I/O on the subsequent retries. 6. The DS4000 Copy Service Remote Mirroring and VolumeCopy features are not supported at this time for DS4100 storage servers. 7. It may take up 12 minutes for the DS4100 to recover after an AC power brown-out event. 8. When connecting DS4000 drive expansion enclosures to the DS4100 storage server, ensure that the unit digits(x1) of the drive expansion enclosure IDs are set to unique values. New for 05.42.06.xx 9. There is not support for converting an existing DS4100 single controller setup (DS4100 storage server model 1S_) to a DS41000 dual controller setup (DS4100 storage server model 100)and vice versa. Please contact IBM resellers or representatives for such support in the future. 10. There is not support for migrating arrays between a DS4100 single controller setup (DS4100 storage server model 1S_) and a DS41000 dual controller setup (DS4100 storage server model 100)and vice versa. Please contact IBM resellers or representatives for such support in the future. 11. There is not support for drive port in the DS4100 single controller CRU. The DS4100 storage server model 1S_ does not support DS4000 EXP drive expansion enclosures. Please contact IBM resellers or representatives for such support in the future. 12. 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 servive 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 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 13. 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 - PR 82146) 14. When connecting the EXP100 enclosures, one must set the single digit (X1) of the enclosure ID to unique values. This is to prevent the possiblity that the controller blade has the same ALPA as one of the drives in the EXP100 enclosures under certain DS4000 controller reboot scenarios.

The ideal configuration for SATA drives is one drive in each EXP per array, one logical drive per array and one OS disk partition per logical drive. This configuration minimizes the random head movements that increase stress on the SATA drives. As the number of drive locations to which the heads have to move increases, application performance and drive reliability may be impacted. If more logical drives are configured, but not all of them used simultaneously, some of the randomness can be avoided. SATA drives are best used for long sequential reads and writes. 2. IBM recommends 1 hot spare per DS4100 storage server 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 storage subsystem (machine type 1724): The standard 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 storage server 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. 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 DS4100 Storage Subsystem (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 on this subject and the DS4100 storage server power on and power off sequence. ======================================================================= 4.0 Configuration Information ----------------------------- 4.1 Configuration Settings -------------------------- 1. By default the IBM DS4000 Storage Manager 9.1 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 9.1. 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 Storage Server as boot devices, contact IBM support for supported configurations and instructions for configuring LUNs in the IBM storage server 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 automatic logical 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. ======================================================================= 4.2 Unsupported configurations ------------------------------ The following lists configurations that are currently not being supported with IBM DS4000 Storage Manager 8.42. 1.
