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

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

   This IBM Storage Manager release includes the IBM FAStT Storage 
   Manager version 8.41 for Windows 2000 only. The \Win32 and the \Docs
   CD-ROM directories contain the documentation and files necessary for
   installing the IBM FAStT Storage Manager software version 8.41 for 
   Windows 2000. This version of the Storage Manager software is 
   required to manage IBM FAStT Storage Servers configured with the 
   IBM SATA drive expansion enclosures FAStT EXP100. These FAStT Storage 
   Servers will have firmware 05.41.xx.xx level installed. For this 
   release of FAStT Storage Manager software version 8.41, Windows NT4 
   and Windows Server 2003 will not be supported. 

   The IBM FAStT Storage Manager version 8.4x Installation and Support
   Guide for Intel-based Operating System Environments is also available
   on IBM's Support Web Site as a downloadable Portable Document
   Format (PDF) file. 
          
   This version 8.41 of IBM FAStT Storage Manager software has 
   controller firmware for IBM machine types 1722-60X/60U (with 
   Turbo or Standard option) and 1742-90X/90U only. The FAStT 
   Storage Controller firmware 05.41.xx.xx for this release 
   is not available for IBM machine types 3542, 3552 and 1742-1RU/1RX.
   However, the host software of IBM FAStT Storage Manager 8.41 will
   manage all FAStT storage server with the controller firmware 
   04.00.02.xx or newer. Any new features and updates that are introduced 
   in this FAStT Storage Manager version 8.41 will not be available for any 
   FAStT storage server controllers without the firmware version 05.40.xx.xx
   installed.


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

1.2  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 rediscovered and 
   managed using the IBM FAStT Storage Manager software.

2. 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. 

3. The Disable/Enable and Uninstall menu functions will be displayed
   when you right-click the RDAC Multi-Path Pseudo-Bus entry in SCSI
   and RAID controllers list of the Device Manager folder. The folder
   is in the Computer Management window. You should not use these 
   menu functions but rather using the Add/Remove program function
   in the Control Panel window to uninstall or to disable the IBM 
   FAStT Storage Manager RDAC device. To reenable the IBM FAStT 
   Storage Manager RDAC device, follow the instructions in the IBM 
   FAStT Storage Manger version 8.4x Installation and support guide 
   for Intel-based Operating System Environments. In addition, if 
   you are upgrading from an older version of FAStT Storage Manager
   version 8.4 RDAC to a newer version, do not uninstall and install
   the new RDAC version; but rather let the new RDAC installation
   program removing/updating the old RDAC with the newer version.  

4. You must always uninstall IBM FAStT Storage Manager RDAC before 
   you uninstall the Host Bus Adapter driver. Failure to do so may 
   result in system hung or blue-screen. 

5. When the FAStT storage subsystem controller firmware is upgraded 
   from any version 05.00.xx.xx or earlier to version 05.2x.xx.xx or 
   later, all of the Windows 2000 servers that had LUNs mapped in this
   storage subsystem must be rebooted after the new FAStT storage 
   subsystem controller firmware and NVSRAM are successfully applied. 
   The reason is that when the new FAStT storage subsystem controller 
   firmware is installed, the controller returns the first four bytes
   of the firmware revision in the Product Revision field of the SCSI
   LUN inquiry data. Windows 2000 uses the Product Revision data as 
   part of the LUN identification. So, as the Product Revision data 
   changes due to the new firmware revision level, Windows 2000 
   thinks that the LUNs with the old Product Revision data were 
   removed from the server. When the 'scan for hardware changes' task
   is executed by running the FAStT storage manager hot_add utility
   or by selecting the Scan For Hardware Changes menu option of the 
   Devices folder in the Computer Management window, Windows 2000
   displays Unsafe Removal of Devices dialogs for these LUNs. The
   devices in these dialogs are RDAC Virtual Disks and xxxx SCSI 
   devices where xxxx are either 1742, 3552 or 3542 depending on the
   model type of  FAStT storage server(s) that the Windows 2000 
   server had LUNs mapped from. The Windows 2000 server will lose 
   connectivity to the LUNs in the FAStT storage that has firmware
   updated. The server must be rescanned for hardware changes. If
   the logical drives are not added back to the server, one must 
   reboot the server to reconnect to the logical drives. 

   This problem will not occurred when upgrading the FAStT storage 
   subsystem controller firmware from version 05.20.xx.xx to version
   05.3x.xx.xx or later because the product revision data field was 
   fixed at 0520.

6. When the server HBA ports are directly connected to the FAStT 
   storage server controllers, do not download firmware and NVSRAM 
   files to the controllers with IOs being generated to the LUNs in 
   the FAStT storage server. There is no IOs restriction in SAN
   Fabric environment ie. the HBA port are connected to the FAStT
   storage server controller ports via Fibre Channel switches. However,
   it is best practice to schedule the upgrade when the expected IO 
   level to the FAStT storage subsystem is low.
   
7. The supplied SMrepassist utility did not utilize Microsoft Volume
   Shadow Services APIs to quiesce the LUNs. Appropriate steps are 
   still need to shut down/quiesce the applications like MS Exchange
   and SQL Server before the FlashCopy logical drive can be made.

8. Rebooting host server may cause its mapped LUNs move to non-preferred
   path. Use Storage Manager client program to redistribute the LUNs to
   their preferred path.

9. Uninstalling RDAC may cause Windows Dynamic disks to fail. After the
   new RDAC is installed and the server is rebooted, these disks must be 
   reactivated and Chkdsk must be run. The work-around is to stop the
   applications and remove the drive letters or the mount points to 
   these disks before uninstalling and reinstalling RDAC.
   
10. The current RDAC driver will coexist with Storport model driver as
    long as it is not the driver for the adapter that talks to the LUNs
    in the FAStT storage subsystems. Note: the current release drivers
    for all of the Fibre Channel host bus adapters that FAStT storage
    subsystem supported are based on the Scsiport model.
     
11. There is not 64-bit version of the FAStT Management Suite Java 
    (FAStT_MSJ). Use the 32-bit version of the FAStT Management Suite
    Java for the Windows Server 2003 64-bit edition. However, one
    should uninstall it once the diagnostic is completed. It could 
    cause the server to bluescreen in heavy IO loads.
    
12. In Xseries x330 server, when two of the Dynamic disks are mirrored
    together by the Windows OS, it may cause the server to hang after
    the LUN that these disks are defined on fail-over/fail-back. There
    is no work-around.  
    
13. 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.

14. This behavior applies for the direct Fibre Channel connection 
    setup between the FAStT F600 storage server host ports and the 
    server HBA ports only. If all FAStT F600 host ports are occupied,
    the FAStT600 event log may show "host-side data rate negotiation
    failed" error when the server is booted up, this is normal 
    error that were generated during the host rate negotiation
    routine inside the FAStT 600 storage server.

15. Windows 2000 and Windows Server 2003 shared the following host 
    type options:
    - Windows 2000/Server 2003 non-clustered
    - Windows 2000/Server 2003 clustered

    If these host types do not appeared in the host type pull down menu,
    use these host type options instead.
    - Windows 2000 non-clustered
    - Windows 2000 clustered

16. In addition to normal disk IOs, clustering services like Microsoft 
    MSCS must be stopped if the user, cluster and quorum disks are 
    defined using the logical drives created in the FAStT EXP100 
    enclosures whose ESMs are being updated with new firmware.
    
17. In a direct Fibre Channel connection between the FAStT storage 
    server and the HBAs in the host server, the system bluescreen
    may occurred if the FAStT storage server is powered off. The 
    work around is to power down the server first before power down 
    the FAStT storage server.
    
18. The FAStT strorage server when configured with the FAStT EXP100 
    SATA Drive Expansion Unit is currently reporting a higher frequency 
    of informational events such as Destination Driver Events (DDEs) 
    and FibreChannel link up/down events ... in the FAStT Controller event
    log compared to the FAStT strorage server configured with Fibre Channel 
    drives. Slower response times of SATA disk drives compared to Fibre 
    Channel disk drives cause higher I/O retries from the FAStT storage server 
    controllers, resulting in a greater number of informational events logged.
    In addition, the number of information events reported in the FAStT 
    strorage server event log will also grow in proportion to the increase 
    in I/Os to the Logical Drives. In all cases, the FAStT storage server 
    controller will always successfully service the timeout I/O on the 
    subsequent retries.

1.3  Enhancements
-----------------
     N/A

=======================================================================
            
1.4  Prerequisites
------------------

   If the host type of either the Default Group or the defined host 
   ports in a storage mapping partition is set to "Windows NT ...", 
   it could take up to 2 hours to boot a Windows 2000 host after 
   installing Windows 2000 RDAC driver. One must make management 
   connection to the storage subsystem via Ethernet ports (out-of-
   band management) and set the host type to the "Windows 2000/ ..." 
   setting.

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

=======================================================================
                                
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 feature
     enabled. Four partition, eight partition, an upgrade from four
     to eight partition and an upgrade from eight to sixteen partition
     storage partitioning premium feature options can be purchased.
     
     A Turbo option is available for the FAStT600 which includes an
     eight partition storage partitioning premium feature option. The
     FAStT600 with Turbo option can have up to 64 storage partitions
     via 8 to 16 partition and 16 to 64 partition storage partition 
     premium feature upgrade options.  

   - 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.

3. Do not delete the Access LUN or Access Volume. The Access LUN is required
   by the SMclient to communicate with the storage controllers when using the 
   in-band management method.

4. The RDAC driver must be digitally signed by Microsoft in order for it to
   work correctly. Always use the IBM provided signed RDAC driver package.

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

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

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


1. By default, the IBM FAStT Storage Manager 8.41 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.
   
   For a new installation, after creating new arrays and logical drives; 
   a. If the host OS type is not Windows NT, create a partition with the
      appropriate OS host type and map the logical drives to this partition. 
   b. If your host OS type is Windows NT non-clustered (SP5 or higher),
      you can map your logical drives to the "Default Host Group" or 
      create a partition with Windows non-clustered (SP5 or higher) host
      type.   
                                 
   When upgrading from previous versions of IBM FAStT Storage Manager
   to version 8.4x. 
   a. If you are upgrading with no defined storage partitions in 
      operating system other than Windows NT, you will need to create
      a storage partition with the appropriate operating system host
      type and map the logical drives from the "Default Host Group" 
      to this partition.
   b. If you are upgrading with defined 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 to
      this operating system host type after upgrading. The FAStT 
      Storage Manager upgrading will reset the default host type to
      Windows NT host type. 
              
   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 and 1742 storage 
   controllers as boot devices, contact IBM support for supported 
   configurations and instructions for configuring LUNs in IBM FAStT 
   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 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. 

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