The \SM8clientcode directory contains the files necessary for installing the IBM FAStT Storage Manager Host Software. The IBM TotalStorage FAStT Storage Manager version 8.4x Installation and Support Guide for Intel-based Operating System Environments is also available on the IBM TotalStorage™ Disk Storage Systems Technical Support web site as a downloadable Portable Document Format (PDF) file. The IBM FAStT Storage Manager version 8.4 upgrade option is a purchase upgrade for IBM machine types 1722 and 1742 with controller firmware version 05.3x.xx.xx and earlier installed. Please contact your IBM service representative or IBM resellers for purchasing info. This version 8.4 upgrade of IBM FAStT Storage Manager software has controller firmware for IBM machine types 1722-60X/60U (with Turbo or Standard option), 1742-1RX/1RU and 1742-90X/90U only. The FAStT Storage Controller firmware 05.40.xx.xx for this release is not available for IBM machine types 3542 and 3552. However, the host software of IBM FAStT Storage Manager 8.4 will manage all FAStT storage server with the controller firmware 04.00.02.xx or newer. But, any new features and updates that are introduced in this FAStT Storage Manager version 8.4 will not be available for any FAStT storage server controllers without the controller firmware version 05.40.xx.xx installed. The latest codes for the IBM FAStT products are available on IBM TotalStorage™ Disk Storage Systems Technical Support web site. http://www.ibm.com/storage/support/fastt ======================================================================= 1.2 Limitations --------------------- 1. In the Storage Manager 8.4 Client, Storage Partitioning must be enabled with the host type of 'linux' selected and the UTM must be removed from the 'Linux' storage partition. Otherwise the correct drive information is not presented to the Linux operating system. 2. When updating Firmware or NVSRAM with high disk activity a controller may become unresponsive during the update. IBM recommends that disk I/O be stopped during these code updates. 3. 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 powering on the controller only without any drive expansion enclosures), 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 8.3 software. 4. 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. 5. 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. 6. If you define a large number of arrays, you will not be able to right-click a logical drive and get a pop-up menu in the Physical View of the Subsystem management window. You must use the Logical Drive pull-down menu to select the logical drive options. 7. 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. 8. 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. 9. When using a 64-bit Linux system the FAStT Storage must be managed from a 32-bit system using the out-of-band management method. 10. Dynamically changing the cache read ahead multiplier setting via the storage manager client may result in an error message indicating the operation has failed. Despite the error message, the request to change the cache read ahead multiplier will remain queued to the controllers and will eventually complete when I/O activity to the storage subsystem has subsided. In order to avoid the error message and any delays in the cache read ahead multiplier value changing, it is recommended to change the cache read ahead multiplier when the subsystem is in a quiesced state. 11. This following behavior applies for the direct Fibre Channel connection setup between the FAStT F600 storage server host ports and the server HBA ports only. If all FAStT F600 host ports are occupied, the FAStT600 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 FAStT 600 storage server. 12. When configuring FAStT Logical volumes to be used with Veritas Volume Manager on Solaris, the maximum capacity per disk is limited to 999GB. For 1024GB disk group support using Veritas Volume Manager, it is recommended to use multiple disks of sizes less than 999GB. 13. When managing the FAStT Storage Servers 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. 14. When migrating array(s) from a dual controller FAStT storage server to a single controller FAStT storage server, 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 FAStT storage server. Otherwise, the array(s) will not be added to the single controller FAStT storage server correctly which might cause problems. 15. When saving the FAStT storage server event log entries, it may take up to several minutes to save all entries in the event log depending on the FAStT management workstation resources. However, the FAStT 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. 16. 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. 17. When managing a single controller FAStT Storage Server 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. ======================================================================= 1.3 Enhancements --------------------------- N/A ======================================================================= 1.5 Dependencies -------------------------- IBM FAStT Storage Manager version 08.4x.xx.xx provides full management support for IBM machine types 3552 and 3542 storage controllers that have at least firmware version 04.00.02.xx, 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.

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, sixteen and an upgrade from four to eight partition storage partitioning premium feature options can be purchased. The IBM FAStT600 Turbo option comes with 8 partition storage partitioning premium option installed. An upgrade to 64 partitions can be purchased for the IBM FAStT600 Turbo option. - 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 8.4 firmware does not automatically map logical drives when the IBM FAStT storage partitioning premium feature is enabled. This means that the logical drives after being created are not automatically presented to the host systems. a. For a new installation, after creating new arrays and logical drives, if your host OS type is any of the supported version of Linux OS's, create a partition with the host type of Linux and map the logical drives to this partition. b. If you are upgrading with Storage Partitions and the host system OS was other than Microsoft 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 non-clustered (SP5 or higher). 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 controllers as boot devices, contact IBM support for supported configurations and instructions for configuring IBM storage controllers as boot devices. 3. When you are configuring IBM machine type 1742 or 3552 storage controllers in clustered Remote Mirror configurations, contact IBM support for supported cluster configurations and instructions for configuring IBM storage controllers in clustered Remote Mirror configurations. ======================================================================= 4.2 Hardware status and information -------------------------------------------------- New installations for IBM Machine types 1722, 1742, 3542,and 3552 should be installed with the IBM FAStT and FC-2/FC2-133 Host Adapter.
