1.0   Overview
-------------------

1.1  Overview
-------------------

   This IBM Storage Manager release includes the IBM FAStT Storage
   Manager version 8.21 for Linux.  The linux CD-ROM directory contains
   the documentation and files necessary for installing the IBM FAStT
   Storage Manager Software version for Linux.

   The IBM FAStT Storage Manager version 8.2 Installation and Support
   Guide is also available on IBM's Support Web Site as a downloadable
   Portable Document Format (PDF) file. The latest Firmware and NVSRAM
   files for IBM machine types 1742, 3542 and 3552 are available on
   IBM's Support Web Site.

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

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

1. In the Storage Manager 8.21 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.

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
   05.2x.xx.xx is connected to a SAN with more than 64 Host ports 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 ports that can be seen and log into the controller is
   64.

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 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.

12. 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.

13. 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.
    
14. 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 

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

3.1  Step-by-step instructions for this code update are as follows
-----------------------------------------------------------------------------------------

1. Install and update the driver for the IBM FAStT Host Adapter.

   a. Install the hardware by using the instructions that come with the
      adapter.
   b. Install the IBM FAStT Host Adapter driver by using the
      instructions provided in the readme.txt file located in the
      Host_Adapter directory on this installation CD.

2. Install the new Storage Manager version 8.2 software. Refer to
   the IBM FAStT Storage Manager version 8.2 for RedHat Linux
   Installation and Support Guide for detailed installation
   instructions.

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

3.2 Refer to the Host_Adapter directory on this installation CD for
    the applicable drivers.

    Refer to the IBM Support Web Site for the latest supported host
    adapters, device drivers, and updated readme.

    At this time, the supported drivers are as follows:

    1. IBM FAStT Host Adapter device driver version 6.0 for Linux
    2. IBM FAStT FC-2 and FC2-133 Host Bus Adapter device driver 
       version 6.0 for Linux

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

3.3  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 RedHat, create a partition with your
      host type of Linux and map the logical drives 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 in clustered Remote Mirror configurations,
   contact IBM support for supported cluster configurations and
   instructions for configuring IBM storage controllers in clustered
   Remote Mirror configurations.

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

4.2 Hardware status and information
--------------------------------------------------

   New installations for IBM Machine types 3542, 1742 and 3552 should be
   installed with the IBM FAStT Host Adapter and Device Driver version
   6.0.
   For more information, refer to the IBM Support Web site.
