Last Update: 10/13/2003 ======================================================================= CONTENTS -------- 1.0 Overview 2.0 Change History 3.0 Usage Notes - AIX Platforms 4.0 WEB Sites and Support Phone Number 5.0 Trademarks and Notices 6.0 Disclaimer ======================================================================= 1.0 Overview ------------ 1.1 Overview ------------ This IBM Storage Manager release includes the IBM FAStT Storage Manager version 8.40 for AIX. In addition, it includes the controller firmware version 05.40.xx.xx and the latest NVSRAM files for IBM machine types 1722, 1742, and 1742-900. The AIX CD-ROM directory contains the documentation and files necessary for installing the IBM FAStT Storage Manager Version 8.40. The "IBM FAStT Storage Manager Version 8.40 for AIX and UNIX environments Installation and Support Guide" is also available on IBM's Support Web Site as a downloadable Portable Document Format (PDF) file. 1.2 Limitations (not AIX limitations, but FAStT/Storage Manager limitations) --------------- 1. 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. 2. 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. 3. If the controller in the IBM FAStT Storage Server with firmware 05.4x.xx.xx is connected to a SAN with more than 256 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. 4. If you define a large number of arrays, you may not be able to right-click a logical drive and get a pop-up menu in the Physical View of the Subsystem management window. The workaround is to use the Logical Drive pull-down menu to select the logical drive options. 1.3 Enhancements ---------------- * FC fast_fail support on AIX 5.1 (10/13/03) * Initial release for base pSeries/AIX support on AIX (9/12/03) v4.3.3, v5.1.0, and v5.2.0 * 1Gb FC SAN attachment to FAStT600.

Having too large of a queue depth can result in lost filesystems and host panics. Please reference the IBM FAStT Storage Manager Version 8.40 for UNIX and AIX Environments Installation and Support Guide for details. * Disabling Cache mirroring while the write-cache is now permitted, but not recommended for most environments and applications. Loss of data could occur in the event of a controller failure (data in cache, but not written to disk). Refer to the Installation and Support Guide for further information. * To manage and configure the FAStT, the SM client, which uses the Java interface resident on the AIX host, must be used with a LAN attachment between the FAStT and the AIX platform (Out of Band management). Any host attached to the LAN with the SM client could also accomplish the management tasks. If In Band management (via the FC interface) is needed, this must be used on a separate host platform that supports the In-band agent software. * FAStT host partitions are restricted to a maximum of 32 Logical Drives on AIX hosts. Support for 256 Logcial Drives will be available in a future release of the AIX RDAC Driver (fcp.disk.array). * SCSI-3 Persistent Reservation is not supported on AIX with FAStT Storage Systems. This feature will be available in a future release of the AIX RDAC Driver (fcp.disk.array). * Each AIX host (server) can support 1 or 2 FAStT Partitions (or Host Groups), each with a maximum of 32 Logical Drives. * For most applications, AIX host attaches to FAStT storage servers using pairs of Fibre Channel adapters (HBA). For each adapter pair, one HBA must be configured to connect to controller "A" and the other to controller "B". Each HBA pair must be configured to connect to a single partition in a FAStT storage server or multiple FAStT Storage servers (fanout). To attach an AIX host to a single or multiple FAStT with two partitions, 2 HBA pairs must be used. * SAN Switch Zoning Rules: Each HBA within a host must be configured in a separate zone from other HBAs within that same host, when connected to the same FAStT controller port. In other words, only 1 HBA within a host can be configured in the same zone with given FAStT controller port. * For most Direct-attach applications, the connections (FC-AL) of FAStT storage arrays on AIX should be configured with two HBAs for complete path availability. As such, dual-path configurations would be restricted to the following: FAStT600 - one or two server configurations only (2 or 4 HBAs) Each HBA pair must be connected to both A & B host-side controller ports. FAStT700/900 - one or two server configurations only (2 or 4 HBAs) Each HBA pair must be connected to both A & B controllers. Only 1 connection on each host-side mini-hub can be used. * Single HBA configurations are allowed, but each single HBA configuration requires that both controllers in the FAStT be connected to the host. In a switch environment, both controllers must be connected to the switch within the same SAN zone as the HBA. In a direct-attach configurations, both controllers must be "daisy-chained" together. This can only be done on FAStT500, FAStT700, and FAStT900. * FAStT volumes that will be used by AIX systems must be configured in an AIX Host Group (partition). Connecting to volumes in the "default" Host Group is not permitted. * Dynamic Volume Expansion (DVE) is only supported on AIX 5.2. * Booting from a FAStT device is only supported on AIX 5.1 and 5.2. * When booting from a FAStT device, both paths to the boot device must be up and operational. Single HBA configurations are supported, but must have both controllers connected, as described above. * Path fail-over is not supported during the AIX boot process. Once the AIX host has booted, fail-over operates normally. * Interoperability with tape devices is supported on separate HBA and switch zones. * Interoperability with IBM 2105 and SDD Software is supported on separate HBA and switch zones. * Online Appware/Snapware and NVSRAM firmware upgrades are not supported on AIX hosts at this time. I/O must be quiesced prior to performing the upgrade. * When using FlashCopy, the Repository Volume failure policy must be set to "Fail FlashCopy logical drive", which is the default setting. The "Fail writes to base logical drive" policy is not supported on AIX, as data could be lost to the base logical drive. * VolumeCopy must be used in conjunction with Flashcopy. The VolumeCopy source volume must be a FlashCopy copy. Refer to the Installation and Support Guide for more information. * AIX Clustering (HACMP, PSSP, GPFS) is not supported at this time with Storage Manager version 8.40. 3.1 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 Drive Enclosure (EXP500 or EXP700) with at least one drive is properly attached to each of the FAStT500 or FAStT700 RAID storage subsystems that are 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 rediscovered and managed using the IBM FAStT Storage Manager 8.3x 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. 3.2 Configuration settings ------------------------------ 1. By default the IBM FAStT Storage Manager 8.3x firmware 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 8.3x. a. If you are upgrading with no defined storage partitions in operating system other than Windows NT, you will need to create a storage partition with the appropriate operating system host type and map the logical drives from the "Default Host Group" to this partition. b. If you are upgrading with defined 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 to this operating system host type after upgrading. The FAStT Storage Manager upgrading will reset the default host type to Windows NT host type. Refer to the IBM FAStT Storage Manager online help to learn more about creating storage partitions and changing host types. ======================================================================= 4.0 WEB Sites and Support Phone Number -------------------------------------- 4.1 IBM TotalStorage Support Web Site: http://ssddom02.storage.ibm.com/techsup/webnav.nsf/support/disk 4.2 IBM TotalStorage Web Site: http://www.storage.ibm.com/ssg.html 4.3 If you have any questions about this update, or problem applying the update go to the following Help Center World Telephone Numbers URL: http://www.ibm.com/planetwide ======================================================================= 5.0 Trademarks and Notices -------------------------- 5.1 The following terms are trademarks of the IBM Corporation in the United States or other countries or both: IBM the e-business logo xSeries HelpCenter AIX Microsoft, Windows, and Windows NT are trademarks of Microsoft Corporation in the United States, other countries, or both.
