=======================================================================
1.1  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.
   
   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 the IBM FAStT Storage Manager 8.2 software.

2. Auto LUN/Array Transfer is not enable for Microsoft Windows, IBM AIX 
   and SUN Solaris OS's. 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 selecting the redistributing arrays menu
   option in the storage subsystem window of the IBM FAStT storage manager 
   client program.

3. 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 8 application in a higher 
   display mode.

4. The FAStT Storage Management dialog windows may be displayed 
   cropped without the vertical and horizontal scroll bars. Just move 
   the mouse pointer over the edge of the window until the mouse pointer 
   change to window resize pointer, left click and hold to grip the 
   window edge to resize it. 

5. If you get "Error 21 - The Operation cannot complete because a 
   ...  is in progress" error when you issue a Subsystem Management 
   command from the IBM FAStT Storage Manager Client, the command may be 
   cached. If the command is cached, the IBM FAStT Storage Manager 
   Client will run the command as soon as the controller resources are 
   available. Wait for at least ten minutes and check to see whether the 
   command has been run. If not, re-attempt the command. 

6. If the controller in the IBM FAStT Storage Server with firmware 
   05.3x.xx.xx is connected to a SAN with more than 64 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. The FAStT Storage Subsystem 
   FAStT900, FAStT700 (IBM machine type 1742) have two ports per controller -
   one per minihub slot. The FAStT Storage FAStT600 (IBM machine type 1722) 
   has two ports per controller. 
   
7. The IBM FAStT Storage Server hardware and software is designed to 
   have redundant paths from the host system to ensure the availability 
   of storage. However, it is possible to connect a single host adapter 
   from the host system to one of the controller minihubs and then 
   connect this minihub to the minihub of the other controller. This 
   configuration will create a FC-AL loop between the host adapter and 
   the two IBM FAStT Storage Server controllers and no redundant path to 
   the host system. When you connect the two minihubs together, always 
   connect the "IN" port of one minihub to the "OUT" port of the other 
   minihub or vice versa. Do not connect the "IN" port of one to the 
   "IN" port of the other minihub or the "OUT" port of one minihub to 
   the "OUT" port of the other minihub.
                     
8. When creating a Remote Mirror of a base volume the following 
   restriction applies. First, you have created a snapshot of a base 
   volume and the base volume is receiving I/O. Second, you decide to 
   create a mirror relationship, using the base volume as the primary 
   volume in the mirrored pair. As you create the mirror relationship, 
   the snapshot volume is failed. The work around is to stop I/O to 
   the base volume while you are creating the mirror relationship. 
   Alternatively, if the mirror relationship is created before creating 
   the snapshot volume, this will not happen.
   
9. Only logical drives that are configured as "Basic Disks" in the 
   Windows Disk Management folder can have Flashcopy made. The 
   Flashcopy of a logical drive configured as "Dynamic Disk" type
   will always failed by the FAStT storage server when it is 
   added to the host server.
    
10. The FAStT Storage Manager version 8.4 does not support Veritas DMP
    in Windows operating system environment. Please contact IBM 
    representatives or resellers for the availability of support.

3.2  Helpful Hints
------------------

1. 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.

2. Depending on the storage subsystem that you have purchased, you
   may have to purchase the FAST storage partitioning premium feature
   option or an option to upgrade the number of supported partitions
   in a storage subsystem. Please see IBM Marketing representatives
   or IBM resellers for more information.
   
   - IBM FAStT600 storage subsystem (machine type 1722): The standard
     configuration does not have the FAST storage partitioning premium
     enabled. Four partition, eight partition and an upgrade from four
     to eight partition storage partitioning premium feature options 
     can be purchased.

   - IBM FAStT700 storage subsystems (machine type 1742 - models 1RU and 1RX): 
     The standard configuration has 64 partitions storage partitioning premium 
     option installed. No additional storage partitioning premium feature 
     options can be purchased for these storage subsystems.

   - IBM FAStT900 storage subsystem (machine type 1742 - models 90X and
     90U): The standard configuration has 16 partition storage partitioning
     premium option installed. An upgrade from 16 to 64 partition storage
     partitioning premium feature option can be purchased.

=======================================================================

4.0 Configuration Information
-----------------------------

        
4.1 Configuration Settings
--------------------------

1. By default the IBM FAStT Storage Manager 8.4 firmware does not 
   automatically map logical drives if storage partitioning feature is
   enabled. 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 8.4. 
   a. If upgrading with no partitions created and you have an operating
      system other 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 partition.
   b. If upgrading with 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.  After upgrading,  the default host 
      type is reset to Windows NT. 
              
   Refer to the IBM FAStT Storage Manager online help to learn
   more about creating storage partitions and changing host types.

2. When you are configuring IBM machine type 1722, 1742, 3542 or 3552 
   storage subsystems as boot devices, contact IBM support for supported 
   configurations and instructions for configuring LUNs in the IBM 
   storage subsystems as boot devices. 

3. 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.
     
4. When you are configuring IBM machine type 1742 or 3552 storage
   controllers in host cluster Remote Mirror configurations, contact 
   IBM support for supported host cluster configurations and instructions
   for configuring IBM storage controllers in clustered Remote Mirror
   configurations. 

=======================================================================

4.2 Unsupported configurations
------------------------------

   The following lists configurations that are currently not being 
   supported with IBM FAStT Storage Manager 8.4.
