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
----------------
* 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 needed to run the resrel.scr script on AIX clustered systems.  This
  fixed with NVSRAM Firmware CNV3552R710NT012

* Fix for Data Errors on pSeries platforms:

  Problem Description:
  --------------------
  Under rare circumstances during extensive stress
  testing and very heavy I/O workloads, an error
  condition involving the fibre channel adapter was
  observed in a laboratory environment.  This error
  may lead to unpredictable results including system crash,
  system hang, data error, unwarranted error log entries, etc.
  This problem has never been reported in a customer
  environment.  Although unlikely, the possibility of  this
  problem occurring in a customer environment does exist.

  User's affected:
  ----------------
  pSeries servers that contain the 6227 or 6228 fibre channel adapter with
  the devices.pci.df1000f7.com fileset at levels below the following:

  AIX 4.3: 4.3.3.83
  AIX 5.1: 5.1.0.28

  Recommendation:
  ---------------
  Apply the appropriate APAR/PTF below in the prerequisites section (1.5).

* 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).

* 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

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, 
  such as Windows 2K.

* 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.

* 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 NVSRAM upgrades are not supported.

* 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 (2 or 4 HBAs)*

	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 8.21.

* For HACMP, PSSP and GPFS Clustering configuration information, see the 
  "PSSP and GPFS configuration information for FAStT500 or FAStT700" or
  "HACMP configuration information for FAStT200, FAStT500 or FAStT700"
  on one the specific FAStT download pages.
