   The IBM FAStT Storage Manager version 8.21 Installation and Support 
   Guides are available on IBM's Support Web Site as a downloadable 
   Portable Document Format (PDF) file. 

   Please see IBM Marketing representatives if you want to upgrade 
   machine type 3552 and 3542 at firmware version 04.xx.xx.xx to 
   firmware version 05.2x.xx.xx because it is a purchased option. In 
   addition, IBM FAStT FlashCopy and IBM FAStT Remote Mirror premium 
   feature options are purchased separate from the Storage Manager 8.2 
   Upgrade option. The IBM FlashCopy option requires firmware version 
   05.00.04.xx or higher and the IBM Remote Mirror option requires 
   firmware version 05.20.0x.xx or higher.

   Refer to the IBM Support Web Site for the latest Firmware and 
   NVSRAM files for IBM machine types 1742, 3542 and 3552.

=======================================================================
1.1  Limitations
---------------------

1. 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.

2. 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.

3. 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.

4. 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.

5. 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. 

6. 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. 

7. If the controller in the IBM FAStT Storage Server with firmware 
   05.2x.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. IBM machine type 1742 and 3552 
   have two ports per controller. In addition, each host minihub in the 
   1742 and 3552 is a single controller port. IBM machine type 3542 has 
   one port per controller.  

8. 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. 
   
9. 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.
                     
10. When using the IBM FAStT Storage Manager 8.2 Remote Mirroring 
    Premium Feature. The maximum number of logical drives supported is 
    reduced to 256 Logical Drives for Machine Type 1742 and 16 mirrors 
    and 128 Logical Drives and 8 mirrors for Machine Type 3552. Remote 
    Mirroring is not supported on the machine type 3542. 
   
11. The help button in the IBM FAStT Storage Manager 8.2 "Create a 
    Flashcopy Logical Drive Wizard" does not work. The workaround is to 
    search for Flashcopy in the Enterprise Management Window online help.

12. 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.
    
13. When one clicks the OK button in the Locate Drive Channel window
    to stop Locating the Drive Enclosures on a given drive channel, the
    blue LEDs in all of the drive enclosures in the located drive 
    channel change from "blinking" to solid "ON" state. To turn off
    the blue LED, one must locate each drive enclosure using the Locate 
    Enclosure button in Drive Enclosure Component window. When the "OK"
    button is click to stop locating drive enclosure, the blue LED for
    that drive enclosure is turned off. To open the Drive Enclosure
    Component window for a drive enclosure, click the Drive Enclosure 
    Component button in its drive enclosure window frame in the 
    subsystem management Physical View window.   

14. The IBM TotalStorage EXP700 drive enclosure blue locator LED is  
    not supported when the EXP700 was connected to the FAStT200 storage
    subsystem.

3.0   Installation and Setup Instructions
-----------------------------------------

3.1  Important: You must install the firmware update prior to downloading  
                the NVSRAM update.

   To download firmware, do the following: 
   
   a.  Open the Subsystem Management window. 
   b.  Click Storage Subsystem => Download => Firmware. 
       Follow the online instructions.

   To download NVSRAM, do the following: 
   
   a.  Open the Subsystem Management window. 
   b.  Click Storage Subsystem => Download => NVSRAM. 
       Follow the online instructions.

=======================================================================
                                
3.2  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 EXP500 Expansion Unit with at least one drive is 
   properly attached to the FAStT500 RAID Controller Unit in each 
   storage subsystem that is 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 re-discovered and 
   managed using the IBM FAStT Storage Manager 8.2 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.

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

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

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

1. By default the IBM FAStT Storage Manager 8.21 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 8.21. 
   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 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. 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, 3542 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 8.21.

   1. Fibre Channel loop environments with the IBM Fibre Channel Hub, 
      machine type 3523 and 3534, in conjunction with the IBM Fibre Channel 
      Switch, machine types 2109-S16, 2109-F16 or 2109-S8. In this 
      configuration, the hub is connected between the switch and the IBM 
      Fibre Channel RAID Controllers.

   2. The IBM Fibre Channel Hub, machine type 3523, connected to IBM 
      machine type 1742, 3542 and 3552.
