Last Update: 12/28/01 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 IBM Storage Manager release includes the IBM FAStT Storage Manager version 7.10 for Windows NT 4.0 and Windows 2000. The Win32 CD-ROM directory contains the documentation and files necessary for installing the IBM FAStT Storage Manager Software version 7.10 for Windows NT and Windows 2000. The IBM FAStT Storage Manager version 7.10 Installation and Support Guide is also available on IBM's Support Web Site as a downloadable Portable Document File (PDF) file. 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 says 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. Upgrading to 16 storage partitions on machine type 3542. Upgrading to Storage Manager 7.10 firmware version 04.01.02 and NVSRAM will enable 16 storage partitions on machine type 3542. However, the Storage Manager Client will indicate that the storage controller premium features are Out of Compliance. To clear this message, contact IBM Support and provide your feature enable Identifier. You can obtain your Feature Enable Identifier from the Subsystem Management window of Storage Manager 7. Use the following procedure to obtain your Feature Enabler Identifier: Click storage subsystem -> premium features -> list Contact IBM Support to obtain a feature key file for enabling the 16 partition premium feature. Refer to the Storage Manager 7 online help for more information. 3. The Windows 2000 RDAC Driver will not contain a Microsoft Digital Signature. When you install the IBM FAStT Storage Manager RDAC (version 07.10.95.06) software package for the first time, the following message will appear: Software Package Unknown This message is expected and the user should proceed with the installation of the IBM FAStT Storage Manager RDAC software package. 4. 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. 5. 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. 6. 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. 7. 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). 8. Redundancy check on machine type 3542 can take up to 10 times longer than on other controller platforms. A redundancy check (parity scan) uses the VERIFY operation which is not implemented in hardware on this platform. Parity checking will take a longer on 3542 based arrays. 9. If the FAStT Controller and EXP enclosures each have a fault condition such as a failed power supply, failed fan, etc.. When the host boots up or the Host adapter device driver is loaded with the FAStT enclosures in this state, some Fibre channel logical drives may not appear. Multiplereboots of the host may show different LUNs as inaccessible. This behavior will be fixed in a future version of the FAStT Controller firmware. As this condition is caused by multiple enclosures having Unit attentions, you must fix whatever is causing the unit attention on all the enclosures, then reboot the affected hosts. See the Recovery Guru in the FAStT Storage Mangaer Client for details on the specific Unit Attentions that appear on the affected FAStT system and how to resolve them. 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 ----------------- 1. It is a requirement to have support for greater than 8 LUNS installed before continuing with the installation. To support more than 8 LUNS, you must install Windows NT Service Pack 5 or greater. 1.5 Dependencies ---------------- IBM FAStT Storage Manager version 7.10 requires machine type 3526, 3542,or 3552 controllers that have at least firmware version 04.xx.xx.xx. If the user is installing IBM FAStT Storage Manager version 7.10 onto a host with 3526 controllers that are at firmware 3.x, refer to the IBM FAStT Storage Manager 7 Migrate package located on the IBM Website at http://www.pc.ibm.com/support for instructions on upgrading the controllers to firmware 4.x. ======================================================================= 2.0 Change History ------------------ 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 (Global Hot Spare) failure NVSRAM changes -------------- - 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. 2.1 Key Features added to IBM FAStT Storage Manager from version 7.02 to version 7.10 --------------------------------------------------------------------- 1.

If you are upgrading from Storage Manager 7.0, Storage Manager 7.1 or Storage Manager 7.02, uninstall the following existing Storage Manager 7 packages: a. IBM Fibre Channel Storage Manager 7 Client Package b. IBM Fibre Channel Storge Manager 7 Agent Package c. IBM Fibre Channel Storage Manager 7 RDAC Package 3. Install the new Storage Manager version 7.10 software. Refer to the IBM FAStT Storage Manager version 7.10 for Windows NT and Windows 2000 Installation and Support Guide for detailed installation instructions. 3.2 Refer to the IBM Support Web Site for the latest supported host adapters, device drivers, and updated readme. 3.3 Helpful Hints ----------------- 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 theIBM 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. The NVSRAM in this package will now enable Media Scanning on a new configuration. If this code is installed on an existing FAStT Storage Subsystem you will need to manually enable media scanning for the subsystem and each LUN that has been created. a. In the Subsystem Management go to Storage Subsystem -> Change Media Scan Settings and select Enable background media scan and set the Duration to 30 days. a. From the Subsystem Management Window, either select the Storage Subsystem >> Change Media Scan Settings pull-down menu option or use the right mouse button to select the storage subsystem in the Logical View. Then, select Change Media Scan Settings from the pop-up menu. Result: The Change Media Scan Settings dialog is displayed. b. Check the Enable background media scan checkbox, if it is not already checked. c. Select a number in the spinner box to specify the duration (in days) of the media scan. d. Select OK. Result: The Media Scan settings for the storage subsystem are changed. The Media Scan duration specifies the number of days over which the media scan should run on the eligible logical drives. For efficiency, the storage subsystem controller will complete the media scan at a faster rate when I/O either is not occurring or is very light. Although the media scan may complete more quickly than you have specified, the storage management software will not restart a complete media scan until the specified number of days has elapsed. e. Enabling a Background Media Scan To enable a background media scan for this logical drive, select the Enable background scan check box. See the online help the IBM FAStT Storage Manager for more information on Media Scan. 2. By default the IBM FAStT Storage Manager 7.10 firmware release 04.01.02.xx 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. When upgrading from previous versions of IBM FAStT Storage Manager to version 7.10. a. If upgrading with no partitions created and you have an operating system ther 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 partiton. b. If upgrading with Storage Partitions and an operating system other than Windows NT, you will need to change the host type. The host type can be changed through the Storage Manager 7.10 Storage Partitions host port. After upgrading, the default host type of a Storage Partition is Windows NT. Refer to the IBM FAStT Storage Manager online help to learn more about creating storage partitions and changing host types. 3. When you are configuring IBM machine type 3552 storage controllers as boot devices, contact IBM support for supported configurations and instructions for configuring IBM storage controllers as boot devices. 4. 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 theIBM 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 Hardware status and information ----------------------------------- For more information, refer to the IBM Support Web site. 4.3 Unsupported configurations ------------------------------ The following lists configurations that are currently not being supported with IBM FAStT Storage Manager 7.10. 1.
