Last Update: 6/30/2003 ======================================================================= 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 7.10 for AIX. In addition, it includes the controller firmware version 04.01.02.33 and 04.01.02.34 and the latest NVSRAM files for IBM machine types 3542, and 3552. The AIX CD-ROM directory contains the documentation and files necessary for installing the IBM FAStT Storage Manager Version 7.10. The "IBM FAStT Storage Manager Version 7.10 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. Redundancy checks 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 longer on 3542 based arrays. 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. 5. The IBM TotalStorage EXP700 drive enclosure blue locator LED is not supported when the EXP700 was connected to the FAStT200 storage subsystem. 1.3 Enhancements ---------------- * Support for AIX 5.2 (12/27/02) * Single version of the SM client for both AIX v4.3.3 and 5.1. (12/6/02) * Added support for the p650 and p655 servers. (11/27/02) * Added FAStT boot support. (11/27/02) * Support for accessing 2 FAStT storage partitions per AIX server. (9/13/02) 1.4 Fixes ---------------- * Fix for the need to run the resrel.scr script on AIX clustered systems. This fixed with NVSRAM Firmware CNV3552R710NT012. The script is no longer a requirement. * Device driver configuration and fail-over problems with UTM LUN (access volume) Problem Description: -------------------- When a UTM LUN (access volume) was configured on a storage partition for AIX hosts, unpredictable issues could occur during configuring the device on AIX with config manager. Issues could also be experienced during fail-over conditions. In the previous release of the AIX DD, it was required that the UTM LUN be removed from the configuration on AIX partitions. Recommendation: --------------- Apply the appropriate APAR/PTF below in the prerequisites section (1.5). 1.5 Prerequisites ----------------- The following pSeries & RS/6000 Hardware Platforms are supported for attachment to the FAStT200 and FAStT500: Machine Type Model# pSeries Name 7013 S70 7013 S7A 7015 S70 7015 S7A 7017 S70 7017 S7A 7017 S80 7017 S85 pSeries 680 7025 6F0 pSeries 620 7025 6F1 pSeries 620 7025 F50 7025 F80 7026 6H0 pSeries 660 7026 6H1 pSeries 660 7026 6M1 pSeries 660 7026 H50 7026 H70 7026 H80 7026 B80 pSeries 640 7026 M80 7028 6C4 pSeries 630 7028 6E4 pSeries 630 7038 6M2 pSeries 650 7039 651 pSeries 655 7043 270 7040 671 pSeries 670 7040 681 pSeries 690 7044 170 7044 270 7028 6C1 pSeries 610 7028 6E1 pSeries 610 9076 PCI Nodes: FC 2050 332 Mhz SMP Thin Node FC 2051 332 Mhz SMP Wide Node FC 2052 POWER3 SMP Thin Node FC 2053 POWER3 SMP Wide Node FC 2054 POWER3 SMP HIGH Node FC 2055 SP Expansion I/O Unit FC 2056 375 Mhz POWER3 SMP Thin Node FC 2057 375 Mhz POWER3 SMP Wide Node FC 2058 375 Mhz POWER3 SMP High Node IMPORTANT: The Disk Drives contained within the EXP500 Enclosure must have the latest supported drive firmware.

Client versions: AIX 4.3.3 and 5.1: 07.10.G5.14 * The following platforms can be attached to the same FAStT200 or FAStT500: Windows NT 4 Windows 2000 AIX 4.3.3 or 5.1 Solaris 2.6, 7 and 8 Note: A supported IBM SAN Switch is required when attaching FAStT storage arrays to AIX and non-AIX servers in a Heterogeneous environment. Please see: http://www.storage.ibm.com/hardsoft/disk/fastt/supserver.htm for supported switches and firmware levels. When a host operating system attaches to a FAStT storage array using the RDAC driver, then all hosts attached to the FAStT must use an RDAC driver. Refer to the table below as to which drivers are available for the various supported operating systems. Since AIX runs with an RDAC failover driver only, all other platforms attached to the same FAStT (i.e. other SUN, NT or W2000) need to run with RDAC as well. To support RDAC, when installing FAStT into AIX environments run the "avtdisable.scr" script to disable AVT/ADT (Automatic Volume Transfer or Automatic Disk Transfer). OS Drivers Available -------------- ------------------- Windows NT4.0 AVT & RDAC Windows 2000 AVT & RDAC Novell NetWare AVT Only Linux - RedHat AVT Only AIX RDAC Only Solaris AVT & RDAC HP-UX AVT Only Refer to the http://www.storage.ibm.com/hardsoft/disk/fastt/index.html IBM web page for the latest released code levels. ======================================================================= 3.0 Usage Notes and restrictions - AIX Platforms --------------------------------------------------- * Whenever the NVSRAM code on the FAStT controller is updated, AVT/ADT is automatically enabled and must be disabled with the avtdisable script. * It is important to set the queue depth to a correct size for AIX hosts. Having too large of a queue depth can result in lost filesystems and host panics. Please reference the IBM FAStT Storage Manager Version 7.10 for the FAStT500 in the UNIX and AIX Environments Installation and Support Guide (CG26-7475-01) for details. * 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, then there must be used on a separate host platform that supports the In-band agent software. * Each AIX host (server) can support 1 or 2 FAStT Partitions (or Host Groups). * Each 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. * 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. * 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. * Path fail-over is not supported during the AIX boot process. Once the AIX host has booted, fail-over operates normally. * 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. * Online Appware/Snapware and NVSRAM firmware upgrades are not supported on AIX hosts at this time. I/O must be quiesced. * Direct-attach connections (FC-AL) of FAStT storage arrays on AIX are restricted to the following configurations: FAStT200 - one server configurations only (2 HBAs) FAStT500 - one or two server configurations only (2 or 4 HBAs) Each HBA pair must be connected to both A & B host-side controller ports. Only 1 connection on each host-side mini-hub can be used. * Interoperability with tape devices is supported on separate HBA and switch zones. * Interoperability with Shark and SDD Software is not permitted at this time. * The following Dynamic Features are not supported on AIX hosts at this time: Dynamic Segment Sizing (DSS) Dynamic RAID Migration (DRM) Dynamic Capacity Expansion (DCE) * FAStT500 Storage Servers with Storage Manager 7.10 are limited to a maximum of 100 physical disk drives, 50 per drive loop, for high availability applications. 220 Drives can be attached to systems running FAStT Storage Manager v8.21 or v8.3. * For HACMP, PSSP and GPFS Clustering configuration information, see the "PSSP and GPFS configuration information for FAStT Storage Systems" or "HACMP configuration information for FAStT Storage Systems" on the FAStT500 download page. ======================================================================= 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.
