Last Update: 12/17/2002 ======================================================================= CONTENTS -------- 1.0 Overview 2.0 Change History 3.0 Installation and Setup Instructions 4.0 Configuration Information 5.0 Unattended Mode 6.0 Web Sites and Support Phone Number 7.0 Trademarks and Notices 8.0 Disclaimer ======================================================================= 1.0 Overview -------------- 1.1 Overview ------------- This release includes the IBM FAStT Storage Manager storage controller firmware version 04.01.02.30 and updated NVSRAM files for IBM machine types 3526, 3542 and the 3552. (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. If you are upgrading controller firmware in IBM FAStT500 storage controller with 512MB Cache, you will have to stop I/O, wait until the controller cache flushed and reboot both controllers before upgrading firmware followed by NVSRAM. You can reboot the controllers either by alternately placing the controller offline and then online using the Storage Manager client program or by pressing the Reset button on both controllers. The Reset button is located on the right of the indicator lights in the opening on the front of each controller unit. Follow the procedure listed below to alternately placing the controller offline and then online: a. On a storage management station, start the Storage Manager client program and select a storage subsystem in the Enterprise Management Window. b. Select Tools -> Manage Device to open the Subsystem Management Window. c. In the Subsystem management window, right-click the "A" controller icon and select Place->Offline. Click "Yes" in the Confirm Place Offline window. A few(5) minutes later, the "A" controller will be held in reset (offline) state and have a red "X" over its icon in the Subsystem Management window. d. Wait at least two minutes, right-click the "A" controller icon and select Place->Online. A few(5) minutes later, the "A" controller will be enable and have the red "X" remove from its icon. The time that the controller takes to come online depends on the number and the state of the hard drives and logical drives defined in the storage subsystem. e. To make sure that the "A" controller is seen by the Storage Manager client program as online and optimal, right-click the "A" controller and select "Properties". If the controller is online, a Properties window for the "A" controller will be displayed without an intermediate Error window. If there is an intermediate Error window, repeat this step. e. Repeat steps c-e for the "B" controller. f. To redistribute logical drives between the controllers, select Storage Subsystem->Redistribute Logical Drives menu option. Click "Yes" in the confirmation window. To determine Storage Controller cache level, perform the following: a. On a storage management station, start the Storage Manager client program and select a storage subsystem in the Enterprise Management Window. b. Select Tools -> Manage Device to open the Subsystem Management Window. c. In the Subsystem Management window, either select Storage Subsystem-> Profile (if the controller firmware was of 4.xx family) or select View-> Storage Subsystem Profile (if the controller firmware was of 5.xx family.) It may take a few minutes before the Storage Subsystem profile is displayed. d. Under the Controllers heading, there 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. 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 ----------------- - Added Read Link Status Diagnostics support. - Corrected NVSRAM to enable background media scan without redundancy check. This setting is not changed on existing systems and must be enabled in the Storage Manager Subsystem Management console. 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 04.01.xx.xx. ======================================================================= 2.0 Change History --------------------- 2.1 Problems fixed between IBM FAStT Storage Manager controller firmware 04.01.02.30 to 04.01.02.33(3526,3552) and 04.01.02.34(3542) . ------------------------------------------------------------------ - Added Read Link Status Diagnostics support. - Volume WWN disappeared after GHS failure 2.2 NVSRAM changes ------------------- - Corrected NVSRAM to enable background media scan without redundancy check.

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 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.
