The IBM FAStT Storage Manager version 8.4x (Intel or Unix Operating Systems)Installation and Support Guides are available on IBM's Support Web Site as a downloadable Portable Document Format (PDF) file. In addition, IBM FAStT FlashCopy and IBM FAStT Remote Mirror premium feature options are purchased separately. The IBM FlashCopy option requires firmware version 05.00.04.xx or higher and the IBM Remote Mirror option requires firmware version 05.20.0x.xx or higher. The FAStT storage partitioning premium feature is standard on all IBM FAStT storage subsystems with the exception of the IBM FAStT600 (machine type 1722) storage subsystem. Please contact IBM Marketing representatives or IBM resellers if you want to purchase the IBM FAStT storage partitioning premium feature option for it. Refer to the IBM Support Web Site for the latest Firmware and NVSRAM files for the IBM FAStT Storage Subsystems. ======================================================================= 1.1 Limitations --------------------- 1. Upgrading FAStT500 with 512MB Cache. If you are upgrading controller firmware on a FAStT500 (machine type 3552) with 512MB of cache, you will need to stop I/O and reboot the controller before upgrading firmware followed by NVSRAM. To determine Storage Controller cache level, perform the following: a. On a storage management station start the client software and select a storage subsystem. b. Select Tools -> Manage Device to open the Subsystem Management Window. c. Highlight the Storage Subsystem that you are upgrading and then select Storage Subsystem -> Profile. It may take a little time for it to create the Storage Subsystem profile. d. Under the Controllers heading is an entry that displays information similar to the following example: Cache/processor size (MB): 256/32 If this setting is listed as 512/32 you will need to arrange to perform this upgrade procedure at a time that you can stop I/O to the Storage Subsystem in order to ensure a successful firmware download and installation. 2. 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 FAStT 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 FAStT Storage Manager 8.2 software. 3. Auto LUN/Array Transfer is not enable for Microsoft Windows, 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 FAStT storage manager client program. 4. Display issues when using 256 color settings. A brownish hash pattern is displayed on the windows and in online help when running in 256 color mode. Run the Storage Manager 8 application in a higher display mode. 5. The FAStT Storage Management dialog windows may be displayed cropped without the vertical and horizontal scroll bars. Just move the mouse pointer over the edge of the window until the mouse pointer change to window resize pointer, left click and hold to grip the window edge to resize it. 6. 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 FAStT Storage Manager Client, the command may be cached. If the command is cached, the IBM FAStT 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. 7. If the controller in the IBM FAStT Storage Server with firmware 05.3x.xx.xx is connected to a SAN with more than 64 host connections per controller port that can log into the controllers, one must either use the switch zoning function or rearrange the SAN connections so that only the maximum number of host connections can be seen and log into the controller. The FAStT Storage Subsystem FAStT900, FAStT700 and FAStT500 (IBM machine type 1742 and 3552) have two ports per controller - one per minihub slot. The FAStT Storage FAStT600 (IBM machine type 1722) has two ports per controller. The FAStT storage Subsystem FAStT200 (IBM machine type 3542) has only one port per controller. 8. The IBM FAStT Storage Server hardware and software is designed to have redundant paths from the host system to ensure the availability of storage. However, it is possible to connect a single host adapter from the host system to one of the controller minihubs and then connect this minihub to the minihub of the other controller. This configuration will create a FC-AL loop between the host adapter and the two IBM FAStT Storage Server controllers and no redundant path to the host system. When you connect the two minihubs together, always connect the "IN" port of one minihub to the "OUT" port of the other minihub or vice versa. Do not connect the "IN" port of one to the "IN" port of the other minihub or the "OUT" port of one minihub to the "OUT" port of the other minihub. 9. When creating a Remote Mirror of a base volume the following restriction applies. First, you have created a snapshot of a base volume and the base volume is receiving I/O. Second, you decide to create a mirror relationship, using the base volume as the primary volume in the mirrored pair. As you create the mirror relationship, the snapshot volume is failed. The work around is to stop I/O to the base volume while you are creating the mirror relationship. Alternatively, if the mirror relationship is created before creating the snapshot volume, this will not happen. ======================================================================= 1.2 Enhancements ----------------- - The release of controller firmware version 05.34.xx.xx for the FAStT600 Storage Server, the FAStT600 Storage Server now has the following features: - Support new single controller FAStT600 Storage Server models) (IBM Machine type 1722 models 6LU and 6LX. - Auto negotiated 1G or 2G Fibre Channel speed on Host Fibre Channel interface. - Support for FlashCopy the controller firmware release - Support for IBM TotalStorage FAStT600 Fibre Channel Storage Server.

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 FAST 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 FAStT600 storage subsystem (machine type 1722): The standard configuration does not have the FAST storage partitioning premium enabled. Four partition, eight partition and an upgrade from four to eight partition storage partitioning premium feature options can be purchased. - IBM FAStT200, FAStT500, and FAStT700 storage subsystems (machine type 3542, 3552 and 1742 - models 1RU and 1RX, respectively): 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 FAStT900 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. ======================================================================= 4.0 Configuration Information ----------------------------- 4.1 Configuration Settings -------------------------- 1. By default the IBM FAStT Storage Manager 8.3 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 FAStT Storage Manager to version 8.3. 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 FAStT 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. 4. When you are configuring IBM machine type 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 FAStT Storage Manager 8.3. 1.
