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.

AIX host attachment to the 1722 (FAStT600) and the 1742-90U/90X (FAStT900) 
requires the additional purchase of an IBM FAStT900/FAStT600 Host Kit 
Option. The IBM AIX Host Kit options contain the required IBM licensing 
to attach an AIX Host System to the FAStT900 or FAStT600. Please contact 
your IBM service representative or IBM resellers for purchasing information. 

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.

3.0 Usage Notes and restrictions - AIX Platforms
---------------------------------------------------
* 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 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.

* FC In-band Storage Managerment is supported on AIX 5.1 and 5.2.
  To manage and configure the FAStT on AIX 4.3.3, 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.

* 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) on AIX 5.1 and 5.2.

* Each AIX host (server) can support 1 or 2 FAStT Partitions (or Host Groups), 
  each with a maximum of 256 Logical Drives (AIX 5.1 and 5.2).

  AIX 4.3.3 is restricted to 32 Logical Drives on each partition.

* 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 FAStT700 and FAStT900.

* Storage Partitions and the Default Host Group
  FAStT offers a premium feature called "Storage Partitioning" which enables users 
  to associate a set of logical drives on a FAStT Storage Server that can only be 
  accessed by specified hosts and host ports.  This association of logical drives 
  to a set of hosts and host ports is called a Storage Partition.  The benefit of 
  defining Storage Partitions is to allow controlled access to the logical drives 
  on the FAStT Storage Server to only those hosts also defined in the Storage 
  Partition.

  Without the use of Storage Partitioning, all logical drives appear within what 
  is called the Default Host Group, and they can be accessed by any fibre channel 
  initiator that has access to the FAStT host port.  When homogeneous host servers 
  are directly attached to the FAStT Storage server, access to all logical drives 
  may be satisfactory, or when attached to a SAN, zoning within the fabric can be 
  used to limit access to the FAStT host ports to specific set of hosts. 

  The FAStT600 base product (without the Turbo feature) provides the Default Host 
  Group.  Premium features are available to support four, eight, or sixteen Storage 
  Partitions.  If logical drive access control is required for your configuration, 
  particularly in a SAN or multiple server environments, then it is recommended that 
  you add the option for Storage Partitions.  On other FAStT Storage Servers which 
  include a minimum number of Storage Partitions, Storage Partitioning must be used 
  when configuring logical drives and hosts.

* 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.

* Boot images cannot be used on a volume that has more than 32 LUNs per partition.

* 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 only supported when 
  upgrading from 05.40.06.XX to a new version of 05.40.XX.XX. It is highly 
  recommended that Online FW upgrades be scheduled during low peak
  I/O loads.

  Online upgrades are not supported on AIX 4.3.3.  I/O must be quieced 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 now supported with Storage Manager 
  version 8.40. Please see one of the following Configuration Information 
  documents for specific support information. These are located in the 
  "Important notices and readmes" section on the FAStT support web site.

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.
