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

1.2  Limitations
---------------------

1. In the Storage Manager 8.3 Client, Storage Partitioning must be
   enabled with the host type of 'linux' selected and the UTM must be
   removed from the 'Linux' storage partition. Otherwise the correct
   drive information is not presented to the Linux operating system.

2. When updating Firmware or NVSRAM with high disk activity a
   controller may become unresponsive during the update. IBM recommends
   that disk I/O be stopped during these code updates.

3. Upgrading FAStT500 with 512MB Cache. If you are upgrading controller
   firmware on a FAStT500 (machine type 3552) with 512MB of cache, you 
   will need to stop I/O and reboot the controller before upgrading 
   firmware followed by NVSRAM.

  To determine Storage Controller cache level, perform the following:

  a. On a storage management station start the client software and
     select a storage subsystem.
  b. Select Tools -> Manage Device to open the Subsystem Management
     Window.
  c. Highlight the Storage Subsystem that you are upgrading and then
     select Storage Subsystem -> Profile. It may take a little time for it
     to create the Storage Subsystem profile.
  d. Under the Controllers heading is an entry that displays
     information similar to the following example:

     Cache/processor size (MB):  256/32

   If this setting is listed as 512/32 you will need to arrange to
   perform this upgrade procedure at a time that you can stop I/O to
   the Storage Subsystem in order to ensure a successful firmware
   download and installation.

4. 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 8.3 software.

5. 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.

6. 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.

7. 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.

8. 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 and FAStT500 (IBM machine type 1742 and 3552)
   have two ports per controller - one per minihub slot. The FAStT 
   Storage FAStT600 (IBM machine type 1722) has two ports per
   controller. The FAStT storage Subsystem FAStT200 (IBM machine type
   3542) has only one port per controller.  

9. If you define a large number of arrays, you will not be able to
   right-click a logical drive and get a pop-up menu in the Physical
   View of the Subsystem management window. You must use the Logical
   Drive pull-down menu to select the logical drive options.

10. 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.

11. 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 workaround is to quiesce 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.

     N/A

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

1.4  Prerequisites
------------------------

   The following vendor kernels listed below have been tested and are 
   required for proper support.
   
     Red Hat Advanced Server 2.1 - 2.4.9-e.12 kernel
     Red Hat Linux 7.3 - 2.4.18-19.7.x
     SuSE Linux Enterprise Server 8 - 2.4.19 kernel
        - Powered by UnitedLinux 1.0

    "Direct connection of the FAStT600 to a host system running 
    Microsoft Windows, Novell NetWare or x86 Linux is only supported 
    using the IBM FAStT FC2-133 Host Bus Adapter (HBA), IBM option part 
    number 24P0960 or feature code 2104 with the last 6 digits of the 13 
    digit serial number of the HBA is H21160 or higher. For example, if 
    the serial number is FFC0308H21161, the last 6 digits will be 
    H21161, which indicates that this HBA meets the FAStT600 direct 
    connect prerequisite.  

    In addition, direct connect to the NAS 300G (Machine Type 5196) 
    Model G27 or Model G02 containing Feature Code 3706 is only

3.3  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 FAStT200, FAStT500, and FAStT700 storage subsystems (machine
     type 3542, 3552 and 1742 - models 1RU and 1RX, respectively): 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 8.3 firmware does not 
   automatically map logical drives when the IBM FAStT storage 
   partitioning premium feature is enabled. This means that the logical 
   drives after being created are not automatically presented to the host
   systems.

   a. For a new installation, after creating new arrays and logical drives,
      if your host OS type is any of the supported version of Linux OS's, 
      create a partition with the host type of Linux and map the logical
      drives to this partition.
      
   b. If you are upgrading with Storage Partitions and the host system OS
      was other than Microsoft 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 non-clustered (SP5 or 
      higher).

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