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

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

   This IBM Storage Manager release includes the IBM FAStT Storage
   Manager version 8.4 for Linux. 
   
   The linux directory contains the files necessary to install 
   the IBM FAStT Storage Manager Software version for Linux.
   The controller Firmware and NVSRAM files are located on the Windows
   CD in the Firmware and NVSRAM directories.

   The IBM FAStT Storage Manager version 8.4 Installation and Support
   Guide is also available on the IBM TotalStorage™ Disk Storage Systems
   Technical Support web site as a downloadable Portable Document Format
   (PDF) file. 
   
   The IBM FAStT Storage Manager version 8.4 upgrade option is a purchase 
   upgrade for IBM machine types 1722 and 1742 with controller firmware 
   version 05.3x.xx.xx and earlier installed. Please contact your IBM 
   service representative or IBM resellers for purchasing info. This 
   version 8.4 upgrade of IBM FAStT Storage Manager software has controller
   firmware for IBM machine types 1722-60X/60U (with Turbo or Standard 
   option), 1742-1RX/1RU and 1742-90X/90U only. The FAStT Storage Controller 
   firmware 05.40.xx.xx for this release is not available for IBM machine 
   types 3542 and 3552. However, the host software of IBM FAStT Storage 
   Manager 8.4 will manage all FAStT storage server with the controller 
   firmware 04.00.02.xx or newer. But, any new features and updates that are 
   introduced in this FAStT Storage Manager version 8.4 will not be 
   available for any FAStT storage server controllers without the controller
   firmware version 05.40.xx.xx installed.
   
   Note: The Linux host attachment to the FAStT600 is an additional 
   purchase - IBM FAStT600 Host Kit Option or IBM FAStT600 Feature code.

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

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

1. In the Storage Manager 8.4 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. 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 powering on
   the controller only without any drive expansion enclosures), 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.

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 
   05.3x.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.  

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 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.
 
11. When using a 64-bit Linux system the FAStT Storage must be managed from
    a 32-bit system using the out-of-band management method.  
    
12. Dynamically changing the cache read ahead multiplier setting via 
    the storage manager client may  result in an error message 
    indicating the operation has failed. Despite the error message, 
    the request to change the cache read ahead multiplier will remain 
    queued to the controllers and will eventually complete when I/O 
    activity to the storage subsystem has subsided. In order to avoid 
    the error message and any delays in the cache read ahead multiplier
    value changing, it is recommended to change the cache read ahead 
    multiplier when the subsystem is in a quiesced state.

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
     feature 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 8.4 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.
