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

IMPORTANT:
The listed limitations are cumulative. However, they are listed by the 
FAStT mid-range disk controller firmware and Storage Manager host 
software releases to indicate which controller firmware and Storage 
Manager client software release that they were first seen and 
documented. 

1. Do not cut and paste the information in the DS4000 Storage 
   Manager Version 9 online help into the DS4000 Storage Manager 
   script command window or into the text file that will be used as 
   input for the SMcli script engine. Extra space may be inserted in 
   the required parameter names which will cause error(s) during the 
   script command execution. (IBM problem record 267873)
 
2. Currently, IBM does not support Gold key Premium Feature as a 
   chargeable upgrade. The Gold key Premium Feature is enable or 
   disable depending on the DS4000 mid-range disk system models.

3. The Asynchronous Remote Mirroring utility, asyncRVMUtil, is not
   supported. This utility is used to automatically synchronize the 
   logical drives in the Remote Mirroring pairs. Please contact IBM 
   representatives or resellers for the support of this utility in 
   the future.
4. Upgrading FAStT500 with 512MB Cache. When upgrading controller 
   firmware on a FAStT500 (machine type 3552) with 512MB of cache, 
   all reading and writing to the disk system must be stopped. The  
   controller needs to be rebooted before upgrading controller 
   firmware followed by NVSRAM.

   To determine disk system 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.

5. DS4000 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 if drives   
   do not have power but the controller power is on. The IBM DS4000 
   Storage Manager will prompt you for a password when trying to 
   start the software or when attempting 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 disk system, the storage management software does 
   not find the password data when you attempt password protected 
   operations. Add one drive to the disk system and retry the 
   operation.
   
   If the DS4000 controller unit has power, then turn power off 
   the controller unit. The DS4000 controller unit shall not be 
   powered on until the EXP expansion units are attached and 
   powered on. Properly attach all expansion units (with drives 
   installed), to the DS4000 controller unit and apply power to 
   the EXP. The controller can now be powered on.  At this point 
   the mid-range disk system can be re-discovered and managed using 
   the IBM DS4000 Storage Manager.

6. Auto LUN/Array Transfer is not enable for IBM AIX and SUN Solaris 
   operating systems. If arrays failover to an alternate controller 
   and the failed controller is replaced and then brought back online, 
   the arrays do not automatically transfer to the preferred 
   controller. The operation must be done manually by selecting 
   the redistributing arrays menu option in the storage subsystem 
   window of the IBM DS4000 Storage Manager.
      
7. 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 DS4000 Storage Manager 8 or higher 
   in a higher display mode.

8. The DS4000 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. 

9. 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, 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. 

10. When a FAStT disk system with controller firmware 05.30.xx.xx is 
   connected to a SAN with more than 64 host port logins. Fibre 
   channel switch zoning must be used or the number of SAN 
   connections must be configured to be no more then the maximum 
   allowed number of host login connections allowed by the controller. 
   
   The FAStT500 IBM machine type 3552 has two ports per controller 
    - one per minihub slot. 
   The FAStT200 IBM machine type 3542) has only one port per 
   controller.
 
11. The IBM FAStT mid-range disk system hardware and software is 
    designed to have redundant paths from the host system to ensure 
    the availability of disk 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 
    disk system controllers and no redundant path to the host system. 
    When connecting 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.
                     
12. When creating a Remote Mirror from a base volume the following 
   restriction applies. First, a flashcopy has been created using 
   a base volume and the base volume is experiencing write and 
   read operations. Second, a mirror relationship has been created, 
   using the base volume as the primary volume in the mirrored pair. 
   As the mirror relationship is created, the flashcopy volume fails. 
   
   The work around to this type problem is to stop write and read 
   operations to the base volume while creating the mirror 
   relationship. Alternatively, if the mirror relationship is 
   created before creating the flashcopy volume, the problem will
   not occur.

13. In Microsoft cluster, MSCS configurations, the MSCS service 
    must be stopped and set to manual start after server is 
    rebooted. The Clusdisk driver must be set to offline and the 
    Windows 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 service 
    will not start after the new RDAC driver is installed. 
    The cluster cannot bring the Quorum disk resources online because 
    the disk signature changes caused the problem. 
    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 

14. In a SAN boot configuration, before updating the Windows RDAC 
    driver in a Windows server, one of the two Fibre Channel (FC) 
    cables that are connected to the server must be disconnected. 
    The Windows server will blue screen during the reboot after the 
    un-installation of the RDAC driver if one of the FC cables 
    is not removed. (IBM problem record 258127)

    ---------     -------------------------------------------------
    86156 (86138) Ancient I/O (mode select I/O) 
    85396 (64475) Problem: Controller went into Debugger due to 
                  Bad devnum received from SYMBOL. PANIC during 
                  Start Of Day (SOD).
                  Fix: Changed the call to PANIC into a print statement.
    85738 (85628) Problem: Controller repeatedly reboots during 
                  Dynamic Volume Expansion (DVE). 
                  The controller get a data abort fault when more than 
                  2 volumes are performing Dynamic Volume Expansion.
                  Fix: The volume number array was increased to handle 
                  more then 2 volume numbers.
    85820         Problem: Controller A is attempting to fail a drive 
                  and attempting to suspend volume activity only it 
                  can't get the controller B to quiesce.
                  Fix: Placed a limit on how long a controller should 
                  wait attempting to quiesce volumes.
    85952 (85799) Problem: Storage Manager lost communication with the 
                  array after controller was taken out of the controller 
                  cluster.

    86487 (86424) Problem: Error that happens when an integrated GHS 
                  drive is replaced by the original spared drive but 
                  copyback to the volumes in the volume group is 
                  interrupted by a drive spinning down.
                  Fix: Reset a flag for all volumes that might have 
                  completed operations when it has been determined that
                  the "spared for" drive is failed.

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

ATTENTION: If you have not already done so, please check the 
Dependencies section for ANY MINIMUM FIRMWARE REQUIREMENTS for the 
FAStT mid-range disk system controllers, the drive expansion 
enclosure ESMs and the hard drives in the FAStT configurations 
before upgrading the controller firmware. 
Make any firmware updates as required BEFORE proceeding to upgrade the 
FAStT controller with the firmware and NVSRAM files packaged with this 
README file. FAILURE to observer the minimum firmware requirement might 
cause your FAStT mid-range disk system to be OUT-OF-SERVICE.  

3.1  Updated the firmware of the ESMs in the attached drive expansion
     enclosures to latest levels before the upgrading the controller 
     firmware. 
     Specifically, if the to-be-updated controller is attached to any 
     EXP700 drive expansion enclosures, the EXP700 ESM firmware must

         Note: If the existing controller firmware in the FAStT 
         mid-range disk system is of version 05.30.xx.xx or higher, 
         the drive expansion enclosure ESM firmware can be updated 
         online with no downtime if both ESMs in each of the drive 
         expansion enclosures are functional and one (and ONLY one) 
         drive expansion enclosure is selected in the ESM firmware 
         download window for ESM firmware updating at a time.
     
 3.2 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.
       
3.3 After the controller firmware and NVSRAM is updated, consider
    checking the IBM TotalStorage Support web site for the latest 
    released drive expansion enclosure ESM firmware and the Fibre 
    Channel hard drive firmware. 
    http://www-1.ibm.com/servers/storage/support/index.html
     
   To download drive expansion ESM firmware, do the following: 
   
   a. Open the Subsystem Management window.

3.4 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 FAStT mid-range disk system that has been 
   purchased, there may be a need to purchase the FAStT storage 
   partitioning premium feature option or an option to upgrade 
   the number of supported partitions in a disk system. 
   Please see IBM Marketing representatives or IBM resellers for 
   more information.
   
   - IBM FAStT200, FAStT500, mid-range disk systems 
     (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 disk systems.

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

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

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

1. By default the IBM DS4000 Storage Manager Version 9 client, the 
   controller 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. 
   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 1722, 1742, 3542 or 3552 
   disk systems as boot devices, contact IBM support for 
   supported configurations and instructions for configuring LUNs 
   as operating system 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 FAStT 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 FAStT 
     controllers to have the same World Wide Names.

   - DifferentWWN.scr:  Setup DS4000 controllers to have different 
     World Wide Names. The World Wide Names (node) will be different 
     for each controller pair. The NVSRAM default sets the FAStT 
     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 or 3552 disk system 
   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 DS4000 Storage Manager Version 9.

      machine type 3523 and 3534, in conjunction with the IBM Fibre 
      Channel Switch, machine types 2109-S16, 2109-F16 or 2109-S08. 
      In this SAN configurations, the hub is connected between the 
      switch and the IBM DS4000 controllers.

   2. The IBM Fibre Channel Hub, machine type 3523, connected 
      to IBM machine type 1722, 1742, 3542 and 3552.
