(see section 2.2 below for NVSRAM changes). The IBM FAStT Storage Manager version 7.10 Installation and Support Guide is available on IBM's Support Web Site as a downloadable Portable Document Format (PDF) file. (see Section 6.1 below). 1.2 Limitations ---------------- 1. Upgrading FAStT500 with 512MB Cache. If you are upgrading from IBM FAStT Storage Manager Version 7.02 ( firmware level 04.00.02 or 04.00.03) to IBM FAStT Storage Manager Version 7.10 (firmware level 04.01.02) 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 something 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. 3. Auto LUN/Array Transfer is not supported. 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 redistributing arrays. 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 7 application in a higher display mode. 5. Error message Service Error 100 after installing Storage Manager 7.10 host-agent software. Causes of this include the following: a. The host-agent software does not find any controllers at firmware version 4.x. b. Controllers at firmware version 4.x have the access volume disabled with NVSRAM configuration settings. c. NVSRAM on a controller in a storage subsystem that you are attempting to manage has the access volume logical unit number (LUN) set to a number that is already in use by another logical drive. d. NVSRAM on controllers in a storage subsystem that you are attempting to manage contains an access volume LUN that is not supported by operating systems and installed patches (for example, the access volume is configured as LUN 31, but the operating system and service packs only support 8 LUNs). 1.3 Enhancements ----------------- N/A 1.4 Prerequisites ------------------ Microsoft Windows systems must update the device drivers for the IBM FAStT Host adapters and the IBM FAStT FC-2 Host bus adapters to the 8.1.4.60 driver version prior to updating the Firmware and NVSRAM for the FAStT subsystems to the 04.01.02.30 version. 1.5 Dependencies ----------------- IBM FAStT Storage Manager version 7.10 and 8.2 requires IBM machine types 3526, 3542 and the 3552 storage controllers to have at least firmware version 04.xx.xx.xx. ======================================================================= 2.0 Change History --------------------- 2.1 Problems fixed between IBM FAStT Storage Manager controller firmware 04.01.02.25 to 04.01.02.30. ------------------------------------------------------------------ - Controller mode changing from Active to Passive - D_Block Queue fix - OEM customer seeing numerous RPA battery failures in MEL. - Runtime Diagnostics fails in a Fabric environment if switch fails to return a frame - createHostPort API allows invalid HostPortTypeIndex value - RAID5/6 DEBUG: Reboot due to ancient IO being aborted - controller pair failed to complete their SOD during hot drv pulls - Parity Scan does not complete after controller reset. - Flute 2 (4774) MEL log wraps too soon - Safe Key - Out of Compliance message after power down or controller replacement - NVSRAM Identifier Number not updated on controller insertion - Drive reported failed by one ctrlr, but lun optimal, drive t 2.2 NVSRAM changes ------------------- 1.

The IBM FAStT Storage Manager will prompt you for a password if an attempt is made to manage a storage subsystem where the FAStT RAID Controller Unit does not have access to any hard disk drives. This will occur even if no password has been setup. The automatic discovery will discover each storage subsystem as two separate storage subsystems. To prevent this from occurring, ensure that at least one FAStT EXP500 Expansion Unit with at least one drive is properly attached to the FAStT500 RAID Controller Unit in each storage subsystem that is being managed. 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 7.10 software. 2. 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. ======================================================================= 4.0 Configuration Information ----------------------------- 4.1 Configuration Settings --------------------------- 1. By default the IBM FAStT Storage Manager firmware release 04.01.02.30 does not automatically map logical drives. 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. Refer to the IBM FAStT Storage Manager online help to learn more about creating storage partitions and changing host types. 2. 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. - 3526CTLdual.scr: Enables the detection and error reporting for missing or unresponsive controllers in a 3526 Dual RAID controller configuration. If either RAID controller is removed or not responding, it is detected and reported through the IBM FAStT Storage Manager software. The 3526 NVSRAM default is enabled to detect a missing or unresponsive alternate controller. - 3526CTLsingle.scr: This script disables the detection and error reporting of the missing alternate controller in a 3526 single RAID controller configuration. After executing this script, the IBM FAStT Storage Manager 7.10 software will not report the missing alternate RAID Controller. The machine type 3526 NVSRAM default is enabled to detect a missing alternate controller. - 3526EXPdualPS.scr: This script enables the detection and error reporting of a missing or unresponsive alternate power supply in an IBM Storage Expansion Unit configured with dual power supplies while attached to the 3526. If either Storage Expansion Unit power supply is removed or not responding, it is detected and reported through the IBM FAStT Storage Manager 7.10 software. Machine type 3526 NVSRAM default is enabled to detect a missing or unresponsive alternate power supply in an IBM Storage Expansion Unit. - 3526EXPsinglePS.scr: This script disables the detection and error reporting of a missing alternate power supply in an IBM Storage Expansion Unit configured with a single power supply and attached to the 3526. After executing this script, the IBM FAStT Storage Manager 7.10 software will not report the missing alternate power supply in an IBM Storage Expansion Unit. The 3526 NVSRAM default is enabled to detect a missing alternate power supply in an IBM Storage Expansion Unit. ======================================================================= 4.2 Unsupported configurations ------------------------------ The following lists configurations that are currently not being supported with IBM FAStT Storage Manager 7.10. 1.
