=======================================================================
1.1  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 DS4000 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 DS4000 Storage Manager 8.2 software.

2. Auto LUN/Array Transfer is not enable for IBM AIX and SUN Solaris OS's. 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 selecting the redistributing arrays menu option in the storage 
   subsystem window of the IBM DS4000 storage manager client program.

3. 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 DS4000 Storage Manager Client, the command may be 
   cached. If the command is cached, the IBM DS4000 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. 
                       
4. The DS4000 Storage Manager version 8.42 does not support Veritas DMP
   in Windows operating system environment. Please contact IBM 
   representatives or resellers for the availability of support.

5. The DS4000 storage server when configured with the DS4000 EXP100 
   SATA Drive Expansion Unit is currently reporting a higher frequency 
   of informational events such as Destination Driver Events (DDEs) 
   and Fibre Channel link up/down events ... in the DS4000 Controller event
   log compared to the DS4000 storage 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 DS4000 storage 
   server controllers, resulting in a greater number of informational 
   events logged. In addition, the number of information events reported in
   the DS4000 storage server event log will also grow in proportion to the 
   increase in I/Os to the Logical Drives. In all cases, the DS4000 Storage
   Server controller will always successfully service the timeout I/O on 
   the subsequent retries. 
   
6. The DS4000 Copy Service Remote Mirroring and VolumeCopy features are 
   not supported at this time for DS4100 storage servers.
 
7. It may take up 12 minutes for the DS4100 to recover after an 
   AC power brown-out event.
   
8. When connecting DS4000 drive expansion enclosures to the DS4100 storage
   server, ensure that the unit digits(x1) of the drive expansion enclosure 
   IDs are set to unique values. 
   
   
New for 05.42.06.xx

9. There is not support for converting an existing DS4100 single
   controller setup (DS4100 storage server model 1S_) to a DS41000 dual 
   controller setup (DS4100 storage server model 100)and vice versa. 
   Please contact IBM resellers or representatives for such support in 
   the future.

10. There is not support for migrating arrays between a DS4100 single
    controller setup (DS4100 storage server model 1S_) and a DS41000 dual 
    controller setup (DS4100 storage server model 100)and vice versa. 
    Please contact IBM resellers or representatives for such support in 
    the future.

11. There is not support for drive port in the DS4100 single controller 
    CRU. The DS4100 storage server model 1S_ does not support DS4000 EXP 
    drive expansion enclosures. Please contact IBM resellers or 
    representatives for such support in the future.

12. In MSCS configurations, the MSCS service must be stopped and set to 
    manual start after server rebooting, the clusdisk driver must have to 
    be set to offline and, then, the server must be rebooted before 
    uninstalling the RDAC driver in the server. If the clusdisk driver is 
    not set to offline and the MSCS service is not set to manual start, 
    the MS cluster servive will not start after the new RDAC driver is 
    installed because it can not bring the Quorum disk resource online. 
    The problem is caused by the changing of the disk signatures. The 
    workaround is stated in the first sentence of this paragraph.
    
    To recover from this problem, you must:
     
    1. Look up the old disk signatures of the disk that are defined as
       cluster disk resources. They could be found either in the registry 
       under the 
       HKLM/System/CurrentControlSet/Services/Clusdisk/Parameters/Signatures
       registry key or in the cluster.log file.
    2. Look up the new disk signatures of the disks that are defined as 
       cluster disk resources using the dumpcfg utility that is packaged
       in the Microsoft Windows resource kit. 
    3. Compare the new and old disk signatures. If new disk signature did
       not match the old signature, you have to change the new disk 
       signature to the old disk signature values by using the dumpcfg 
       command. The syntax of the command is 
       
       dumpcfg.exe -s <old-signature> <Disk#>     

       For example,  dumpcfg.exe -s 12345678 0 

13. Before updating the RDAC driver in a server that is setting up as 
    San-boot, one of the two Fibre Channel (FC) cables that are connected 
    to the server must be disconnected. The server will bluescreened 
    during the reboot after the un-installation of the RDAC driver if one 
    of the FC cables was not removed. (258127 - PR 82146)

14. When connecting the EXP100 enclosures, one must set the single digit
    (X1) of the enclosure ID to unique values. This is to prevent the 
    possiblity that the controller blade has the same ALPA as one of the 
    drives in the EXP100 enclosures under certain DS4000 controller reboot 
    scenarios. (261188)

=======================================================================
                                
3.2  Helpful Hints
------------------

1. The ideal configuration for SATA drives is one drive in each EXP per 
   array, one logical drive per array and one OS disk partition per 
   logical drive. This configuration minimizes the random head movements 
   that increase stress on the SATA drives. As the number of drive 
   locations to which the heads have to move increases, application 
   performance and drive reliability may be impacted. If more logical 
   drives are configured, but not all of them used simultaneously, some 
   of the randomness can be avoided. SATA drives are best used for long 
   sequential reads and writes.
 
2. IBM recommends 1 hot spare per DS4100 storage server unit or EXP100 drive 
   expansion enclosure. 

3. 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. Depending on the storage subsystem that you have purchased, you
   may have to purchase the DS4000 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 DS4100 storage subsystem (machine type 1724): The standard
     configuration does not have the DS4000 storage partitioning premium
     enabled. Four partition, eight partition, sixteen partition and an
     upgrade from four to eight partition storage partitioning premium
     feature options can be purchased.

5. When making serial connections to the DS4000 storage controller, the baud 
   rate is recommended to be set at either 38200 or 57600. Note: Do not 
   make any connections to the DS4000 storage server serial ports unless 
   it is instructed by IBM Support. Incorrect use of the serial port 
   might result in lost of configuration, and possibly, data. 

6. Fabric topology zoning requirement. To avoid possible problem at the 
   host level, it is best practice that all Fibre Channel (FC) Switches 
   must be zoned such that a single FC host bus adapter can only access 
   one controller per storage array. In addition, this zoning requirement 
   also ensures the maximum number of host connections can be seen and 
   log into the controller FC host port. This is because if a FC HBA port 
   is seen by both controller A and B host ports, it will be counted as 
   two host connections to the storage subsystem - one for controller A 
   port and one for controller B port.
   
   Note: The DS4100 Storage Subsystem (IBM machine type 1724) has two ports 
   per controller.
      
7. Always connect the power supplies of the DS4100 and its drive expansion
   enclosures to separate power circuits to maximize protection against 
   lost of power. Please refer to the IBM Totalstorage DS4100 
   Installation, User's and Maintenance Guide for more information on 
   this subject and the DS4100 storage server power on and power off 
   sequence.

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

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

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

1. By default the IBM DS4000 Storage Manager 9.1 firmware does not 
   automatically map logical drives if storage partitioning feature is
   enabled. 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 DS4000 Storage 
   Manager to version 9.1. 
   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 DS4000 Storage Manager online help to learn
   more about creating storage partitions and changing host types.

2. When you are configuring IBM machine type 1724 Storage Server as 
   boot devices, contact IBM support for supported configurations and 
   instructions for configuring LUNs in the IBM storage server 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.
   
   - EnableAVT_W2K_S2003_noncluster.scr:  The script will enable automatic
     logical drive transfer (AVT/ADT) for the Windows 2000/Server 2003 
     non- cluster heterogenous host region. The default setting is to 
     disable AVT for this heterogenous host region. This setting is one 
     of the requirements for setting up the remote boot or SAN-boot. Do 
     not use this script unless it is specifically mentioned in the 
     applicable instructions. (This script can be used for other host 
     type if modifications are made in the script, replacing the Windows 
     2000/Server 2003 non-cluster host type with the appropriate host 
     type that needs to have AVT/ADT enabled) 
  
   - DisableAVT_W2K_S2003_noncluster.scr:  The script will disable the 
     automatic logical drive transfer (AVT) for the Windows 2000/Server 
     2003 non-cluster heterogenous host region. This script will reset 
     the Windows 2000/Server 2003 non-cluster AVT setting to the default. 
     (This script can be used for other host type if modifications are 
     made in the script, replacing the Windows 2000/Server 2003 non-
     cluster host type with the appropriate host type that needs to have 
     AVT/ADT disabled) 

   - EnableAVT_Linux.scr:  The script will enable automatic logical drive 
     transfer (AVT) for the Linux heterogenous host region. Do not use 
     this script unless it is specifically mentioned in the applicable 
     instructions. 
  
   - DisableAVT_Linux.scr:  The script will disable the automatic logical
     drive transfer (AVT) for the Linux heterogenous host region. Do not 
     use this script unless it is specifically mentioned in the 
     applicable instructions.
