   The DS4000 Storage partitioning premium feature is standard on all 
   IBM DS4000 storage subsystems with the exception of the IBM DS4100 
   (machine type 1724 with Standard or Single Controller options) and 
   the DS4300 (machine type 1722 with Standard or Single Controller 
   options) storage subsystems. Please contact IBM Marketing 
   representatives or IBM resellers if you want to purchase the 
   IBM DS4000 Storage partitioning premium feature option for it. 
   The Turbo option of the IBM DS4300 is shipped with the IBM DS4000 
   Storage partitioning premium feature enabled (8 partitions).

   The DS4000 Storage Controller firmware 06.12.xx.xx for this release 
   is available for the IBM machine types 1724-100 (DS4100 with 
   standard/base option), 1722-60X/60U (DS4300 with Standard/base or 
   Turbo option), 1742-1RX/1RU and 1742-90X/90U (DS4400 and DS4500) 
   only. The DS4000 Storage Controller firmware 06.12.xx.xx for this 
   release is not available for IBM machine types 3542, 3552, 1724-1SC 
   (DS4100 with Single controller option) or 1722-6LX/6LU (DS4300 
   with Single controller option). However, the IBM DS4000 Storage 
   Manager 9.12 host software for this release will manage all DS4000 
   midrange disk subsystem with the controller firmware 04.01.xx.xx 
   or newer (05.xx.xx.xx or newer in Microsoft Windows environments). 
   But, any new features and updates that are introduced in this 
   DS4000 Storage Manager version 9.12 or higher will not be available 
   for any DS4000 midrange disk subsystem controllers without the 
   controller firmware version 06.12.xx.xx installed.

=======================================================================
1.1  Limitations
---------------------
IMPORTANT:
The listed limitations are cumulative. However, they are listed by the 
DS4000 midrange disk subsystem controller firmware and Storage Manager 
host software releases to indicate which controller firmware and 
Storage Manager host software release that they were first seen and 
documented. 

Limitations with version 06.12.03.xx or higher.

1. Do not cut and paste the information in the DS4000 Storage Manager 
   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. 
   (CMVC 267873)

2. In the configuration that have both SATA-technology drives (EXP100) 
   and Fibre-Channel technology drives (EXP700/EXP710) behind the 
   same DS4000 storage subsystem, do not download drives firmware to both 
   SATA-technology drives and Fibre-Channel(FC) technology drives at the 
   same time. Download the drive firmware to drives of a single drive 
   technology (either SATA or FC) at a time.
    
3. 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 storage subsystem models.

4. 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.


Limitations with version 06.10.11.xx release
     
1. 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 service 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 
   work around 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 

2. 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 (82146))

3. Do not update the DS4000 storage subsystem controller firmware 
   to version 06.1x.xx.xx from versions 05.4x.xx.xx or earlier if 
   the EXP700 ESM firmware of the attached EXP700 was not at 9326 
   or newer. 
If the EXP700
   ESM firmware is earlier than the 9326 versions, the EXP700 enclosure 
   and the installed drives may not be displayed in the DS4000 subsystem 
   management window after the controller firmware is upgraded to 
   06.1x.xx.xx version. The work around is to update the EXP700 ESM 
   firmware to the 9326 or higher version first before upgrading the 
   controller firmware to version 06.1x.xx.xx. (260160 - (82841))
    
4. When connecting the EXP100 drive expansion enclosures, one must set 
   the single digit (X1) of the enclosure ID to unique values. This 
   is to prevent the possibility that one of the drives in the EXP100 
   enclosures be assigned the same ALPA as the DS4000 controller  
   under certain DS4000 storage subsystem reboot scenarios. 
   (261188)


Limitations with version 06.10.06.xx release

1. The DS4000 Copy Service RVM is not supported at this time for the
   DS4100 and the DS4300 storage subsystem with Standard or Single 
   Controller options.
 
2. In the Storage Manager version 9 client Subsystem Management window, 
   the preferred owner of a defined logical drive can not be changed if 
   the  logical drive is not managed by the preferred owner/controller. 
   The Storage Manager client will grey-out (not allowing one to select) 
   the controller that is currently managing the logical drive in the 
   selection of the new preferred owner/controller. One is allowed to 
   only select the controller that is not managing the logical to be the 
   new preferred owner. There is no work-around.
    
3. Concurrent firmware download (downloading firmware/NVSRAM to the 
   DS4000 storage subsystem controllers with I/Os to the host servers) 
   is not supported when upgrading the controller firmware from a 
   05.xx.xx.xx version to a 06.1x.xx.xx version. ALL I/Os must be 
   stopped during the version 06.1x.xx.xx controller firmware 
   upgrade from a 05.xx.xx.xx version. 
    
4. Do not pull or insert drives during the drive firmware download. 
   In addition, ALL IOs must also be stopped during the drive firmware 
   download. Otherwise, drives may be shown as missing, unavailable or 
   failed. 
    
5. Controller diagnostics will not run in a DS4000 storage subsystem 
   with single controller.
    
6. When instructed to remove and reinsert or to replace a hard drive, 
   wait at least 70 seconds before inserting either the removed 
   existing drive or the new drive into the drive slot. Then, wait 
   up to 3 minutes for the drive to be spined up, recognized by the 
   DS4000 storage subsystem and displayed in the Subsystem Management 
   window before repeating the process for another hard drive. 
   There is no work-around available.
   
   Similarly, wait at least 70 seconds before reinserting either the 
   removed existing ESM module or the new ESM module into the empty ESM 
   slot in the EXP drive expansion enclosure. Then, wait up to 3 minutes 
   for the ESM CRU to be recognized by the DS4000 storage subsystem and 
   displayed in the Subsystem Management window before repeating the 
   process for another ESM. There is no work-around available.

7. Staged firmware and NVSRAM download function is not available on the
   DS4400 (machine type 1742) models with firmware 06.1x.00.00 in 
   conjunction with IBM Storage Manager 09.1x.xx.xx.
     
Limitations with Storage Manager version 8.4x.xx.xx (and earlier) and
DS4000 controller firmware version 05.4x.xx.xx (and earlier) releases

1. Auto LUN/Array Transfer is not enable for IBM AIX and SUN Solaris 
   operating systems.
   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.

2. You must use the Add/Remove program function in the Control Panel 
   window to uninstall or to disable the IBM DS4000 Storage Manager RDAC 
   device. To re-install the IBM DS4000 Storage Manager RDAC device, 
   follow the instructions in the IBM DS4000 Storage Manager version 9 
   Installation and Support Guide for Windows 2000/Server 2003, 
   Netware, ESX Server, and Linux.  

3. You must always uninstall IBM DS4000 Storage Manager RDAC before 
   you uninstall the Host Bus Adapter driver. Failure to do so may 
   result in system hang or blue-screen condition.
                       
4. When creating a Remote Mirror of a base logical drive, in the 
   case where a FlashCopy of the base logical drive has already
   been created, the following restriction applies. If the Remote 
   Mirror relationship is created while the base logical drive is
   receiving I/O, the FlashCopy logical drive will be failed. The 
   work around is to quiesce I/O to the base logical drive while you 
   are creating the remote mirror relationship. Alternatively, if the
   Remote Mirror relationship is created before creating the FlashCopy
   logical drive, the FlashCopy logical drive will not be failed. 

5. When alternately switching back and forth the roles of the logical
   drives in a remote mirrored relationship, Windows NT4, Windows 2000
   and Server 2003 may cache the file(s) on the logical drive(disk) in
   memory  and use these cached data instead of going out to the disk
   to get the data. This windows OS behavior may make the data look like
   it was not synchronized between logical drives in a remote mirrored
   relationship. The fix to the problem is to dismount the primary
   logical drive in the server before demoting it to secondary role. 
   In Microsoft Windows environment, this is best done by shutting down 
   the server that the primary logical drive is mapped to. Then, 
   promote the secondary logical drive to the primary role and hot_add
   it to the appropriate server.
    
   If the logical drive is of "Dynamic Disk" type, there is a possible
   solution without requiring server to be shut down. First, in the 
   server that has the primary logical drive, run the SMrepassist 
   program in the DS4000 Storage Manager 8.xx/9.xx util directory 
   with the -f option to flush the cached data to disk. Then, 
   promote the secondary logical drive and hot_add it to the 
   appropriate server.
   Before promoting the logical drive to primary role in the original
   server, force a failure to the disk, for example, by running a chkdsk
   on the disk. Then, promote the logical drive to primary role
   in the original server and hot_add it. One may have to reactivate
   the disk after it is hot_added to the server.
   
   If the server environment prevents the server from being
   rebooted and the logical drive is of "basic disk" type, you may
   use the following steps 

   1. In the server that has the primary logical drive, run the 
      SMrepassist program in the DS4000 Storage Manager 8.3x
      util directory with the -f option to flush the cached data
      to disk.
   2. Using the DS4000 Storage Manager to remove the LUN mapping 
      of the logical drive that had the primary role from its
      server (host computer). 
   3. Promote the secondary role LUN to the primary role and 
      hot_add it in the appropriate server assuming that the LUN  
      mapping is already defined for this server in the DS4000 
      storage subsystem.
   4. Before promoting the logical drive to primary role in the 
      original server, run Hot_add program or initiate a Scan for
      Hardware Changes task in the original server. This is to
      remove the logical drive from the available disks. In W2K,
      you may see Unsafe Removal of Devices messages.
   5. Using the DS4000 Storage Manager to add the LUN mapping of 
      the logical drive that will be promoted to primary role to 
      the original server(host computer). 
   6. Promote the Logical Drive to Primary role and hot_add it in
      the original server. If you are unable to hot_add the logical
      drive or the data still appears to be mismatched, you must 
      reboot the server.  

6. When the DS4000 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 DS4000 Storage 
   subsystem controller firmware and NVSRAM are successfully applied. 
   The reason is that when the new DS4000 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 DS4000 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  DS4000 storage subsystem(s) that the Windows 2000 
   server had LUNs mapped from. The Windows 2000 server will lose 
   connectivity to the LUNs in the DS4000 Storage that has firmware
   updated. The server must be scanned again 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 occur when upgrading the DS4000 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.

7. When the server HBA ports are directly connected to the DS4000 
   storage subsystem controllers, do not download firmware and NVSRAM 
   files to the controllers with I/Os being generated to the LUNs in 
   the DS4000 storage subsystem. There is no I/Os restriction in SAN
   Fabric environment i.e. when the HBA port are connected to the 
   DS4000 storage subsystem controller ports via Fibre Channel switches.
   
8. 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.

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 DS4000 Storage subsystems. Note: the current release drivers
    for all of the Fibre Channel host bus adapters that DS4000 Storage
    Servers support are based on the SCSIport model.
        
11. This following behavior applies for the direct Fibre Channel 
    connection setup between the DS4300 storage subsystem host ports and
    the server HBA ports only. If all DS4300 host ports are occupied,
    the DS4300 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 DS4300 storage subsystem.

12. In a direct Fibre Channel connection between the DS4000 Storage 
    subsystem and the HBAs in the host server, the system bluescreen
    may occur if the DS4000 storage subsystem is powered off. The 
    work around is to power down the server first before powering down 
    the DS4000 storage subsystem.   
       
13. Only logical drives that are configured as "Basic Disks" in the 
    Windows Disk Management folder can have FlashCopy made. The 
    FlashCopy of a logical drive configured as "Dynamic Disk" type
    will always be failed by the DS4000 storage subsystem when it is 
    added to the host server.  

14. There is not an IA-64 version of the DS4000 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 I/O loads.
    
15. Veritas DMP 4.1 is not supported at this time in Windows operating 
    environment. Veritas Volume Manager (DMP) 4.2 is supported with 
    Windows Server 2003 and Windows 2000. 

16. When managing the DS4000 storage subsystems with firmware version 
    05.3x.xx.xx, the Help window of the Subsystem Management window may
    not be displayed correctly the topics that are listed as result of 
    executing a full text search. 

17. When migrating array(s) from a dual controller DS4000 storage 
    subsystem to a single controller DS4000 storage subsystem, you 
    must first set the preferred owner of the to-be-migrated array(s) 
    to be controller A before inserting it into the drive slots of a 
    single controller DS4000 storage subsystem. Otherwise, the array(s) 
    will not be added to the single controller DS4000 storage subsystem 
    correctly which might cause problems.

18. When managing a single controller DS4300 storage subsystem model, 
    do not use the menu option - Configuration->Automatic... - in the 
    Subsystem Management window to create LUNs. You might not be able 
    to access or manage LUNs that are created this way.

19. After you replace a controller with a new controller in the single 
    controller models of DS4000 storage subsystems, the premium features 
    become unauthorized and are out of compliance. Any premium features 
    not supported by the firmware of the new controller are unavailable. 
    The work-around is to upgrade the firmware in the new controller to 
    the same level as the removed controller and re-enable the premium 
    features using the key files that you were provided when the premium 
    feature was originally enabled. 
    
20. When you migrating drive Customer Replaceable Units (CRUs) from 
    multiple DS4000 storage subsystems into a single destination 
    DS4000 Storage subsystems, all of the drive CRUs from the same 
    DS4000 storage subsystem should be moved as a ‘set’ into the new 
    destination DS4000 Storage subsystem. Before moving the next ‘set’ 
    of drive CRUs, ensure that all of the drive CRUs for a single ‘set’ 
    have been moved to the destination DS4000 storage subsystem. 
    If drive CRUs are not moved as a ‘set’ to the destination DS4000 
    storage subsystems, the newly relocated array may not appear in 
    the Subsystem Management window.

21. Enclosure IDs may be listed incorrectly in the Subsystem Management 
    window, even if the Enclosure ID switch settings appear to be 
    correct. This is because of the physical design and movement of the 
    Enclosure ID switch, it is possible to leave the switch in a “dead 
    zone” between ID numbers, which will return an incorrect Enclosure ID 
    (this value is 0 in most cases) to the storage management software. 
    When setting the Enclosure ID, ensure that the switch has actuated 
    completely and has settled where the value is clearly visible in the 
    viewing window.
  
22. To download controller firmware, you must select the drive where the
    firmware is located. If the drive you select does not respond, the 
    File Selection dialog box will revert to the A: drive and display an 
    error message that drive A: is not ready if there are no media in 
    drive A:.

23. You must suspend all I/O while ESM firmware downloads if you select 
    multiple enclosures for downloading ESM firmware. If you select only
    one enclosure for download at a time, you can download ESM firmware
    with I/Os. However, IBM recommends that you suspend all I/O activity
    to perform firmware upgrades. 
    
    Furthermore, if the EXP100 ESM firmware version is 953x or earlier, 
    no I/Os are allowed during the duration that the EXP100 ESMs are 
    being updated with new firmware, including clustering reservation 
    checking IOs. 

24. The DS4000 storage subsystem 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 subsystem 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 subsystem controllers, resulting in a greater number 
    of informational events logged. In addition, the number of 
    information events reported in the DS4000 storage subsystem event 
    log will also grow in proportion to the increase in I/Os to the 
    Logical Drives. In all cases, the DS4000 storage subsystem 
    controller will always successfully service the timeout I/O on 
    the subsequent retries.   

25. When saving the DS4000 storage subsystem event log entries, it may 
    take up to several minutes to save all entries in the event log 
    depending on the DS4000 management workstation resources. However, 
    the DS4000 Storage Manager client GUI will show the completion of 
    the event log saving almost instantly. The work around is to 
    check the file size of the file that the event log entries are 
    saved periodically; if the file size does not change, the event 
    log saving is completed.

26. Do not perform other storage management tasks, such as creating or 
    deleting logical drives, reconstructing arrays, and so on, while 
    downloading the DS4000 storage subsystem controller firmware and 
    DS4000 EXP ESM firmware. It is recommended that you close all 
    storage management sessions (other than the session that you use to 
    upgrade the firmware) to the DS4000 storage subsystem that you plan 
    to update.

27. Inter-operability with tape devices is supported on separate HBA and 
    switch zones.

1.2  Enhancements
-----------------

   IMPORTANT: New features that are introduced with the DS4000 Storage 
   Manager version 9.1x host software will not be available for any DS4000 
   storage subsystem controllers without the controller firmware version 
   06.12.xx.xx installed. The DS4000 storage subsystem controller firmware 
   version 6.12.xx.xx is available for the following DS4000 Storage 
   server only - the DS4100 with Standard option, the DS4300 with 
   Standard or Turbo option, the DS4400 and the DS4500. Please contact 
   your IBM service representative or IBM resellers for the availability 
   of additional DS4000 storage subsystem models support with controller 
   firmware version 6.12.xx.xx in the future. 
   
   A summary list of the new features that are introduced with the 
   DS4000 Storage Manager version 9.12 host software level in 
   conjunction with the DS4000 storage subsystem controller firmware 
   version 06.12.03.00 is as followed:
    
   1. Support for the FC/SATA intermix premium feature enable via a
      premium feature key file. A premium key file, instead of a NVSRAM
      file, is now required to enable the FC/SATA premium feature intermix
      in a DS4000 storage subsystem.
   2. Support for the DS4100 with standard(base) option with controller
      firmware v06.xx.xx.xx code thread. No new premium features are
      available at this time for the DS4100 storage subsystem with the 
      controller firmware version 6.12.xx.xx.
   3. New DS4000 host-software installation wizard that will 
      automatically install the appropriate host-software components 
      depending on the select server type (i.e.. host or 
      management-station.)
   4. Serviceability Enhancement - the ability to extract SMART data 
      for SATA-technology drives.
   5. Usability Enhancement - Added Wizard to Storage Manager SMclient 
      to aid users with Storage Partitioning creation with Hosts, 
      Adapters, and mappings. Added Task Assistant to Storage Manager 
      which helps guide users through common task wizards for both the 
      Enterprise and Subsystem management tasks.    
   6. For HP-UX server configurations with LVM mirrored volume, a fix 
      was implemented to prevent a possible occurrence of an AVT storm 
      caused by the HP-UX server probing in the wrong order of 
      available paths to the volume(s) when it detect server to LUN 
      path failure. 
      This fix requires the controller firmware and NVSRAM be at 
      version 06.12.03.00 or later. 
      The fix is to disabling the DS4000 storage subsystem AVT requests 
      for the HP-UX server specific read pattern of 2 blocks (1024 bytes) 
      at LBA 8192. 
      To disable this DS4000 storage subsystem functionality in HP-
      UX server configurations without LVM mirrored volumes, 
      please refer to the disable_ignoreAVT8192_HPUX.script script 
      described in the 4.1 
      Configuration Settings section. Please contact IBM support for 
      additional information, if required.
      

   Please refer to the New Features section of the IBM DS4000 Storage 
   Manager version 9 Installation and Support Guide for the appropriate 
   host server operating system environment for additional information 
   about the IBM DS4000 Storage Manager version 9 enhancements.

   
=======================================================================
            
1.3  Prerequisites
------------------

     The DS4000 controller firmware and NVSRAM file that are packaged 
     with this README file can ONLY be loaded in the following DS4000
     storage subsystems:
     
     1. DS4100 storage subsystems with Standard Option
     2. DS4300 storage subsystems with Standard or Turbo Option
     2. DS4400 storage subsystems
     3. DS4500 storage subsystems
     
     DO NOT DOWNLOAD this controller firmware on any other DS4000 
     storage subsystem. There is not any checking for this restriction 
     inside the DS4000 Storage Manager client program. In addition, 
     the procedure to recover the DS4000 storage subsystem that was 
     inadvertently loaded with this firmware file will require 
     downtime to the DS4000 storage subsystem. 
     Also see next section - Dependencies. 

=======================================================================
            
1.4  Dependencies
-----------------
   
   ATTENTION:

   1. DS4000 STORAGE SUBSYSTEM CONTROLLER FIRMWARE VERSION 06.1X.XX.XX 
      REQUIRES THAT THE FIRMWARE VERSION OF AN ATTACHED EXP700 
      ENVIRONMENTAL SERVICE MODULE (ESM) BE AT VERSION 9326 OR HIGHER. 
      IF THE EXP700 ESM FIRMWARE IS EARLIER THAN THE 9326 VERSIONS, THE 
      EXP700 ENCLOSURE AND THE INSTALLED DRIVES MAY NOT BE DISPLAYED IN 
      THE DS4000 SUBSYSTEM MANAGEMENT WINDOW AFTER THE CONTROLLER 
      FIRMWARE IS UPGRADED. 
 
   2. DS4000 STORAGE SUBSYSTEM CONTROLLER FIRMWARE VERSION 06.1X.XX.XX 
      REQUIRES THAT THE FIRMWARE VERSION OF AN ATTACHED EXP100 
      ENVIRONMENTAL SERVICE MODULE (ESM) BE AT VERSION 955X OR HIGHER. 
      IT IS NOT POSSIBLE TO UPGRADE EXP100 ESM FIRMWARE VERSIONS THROUGH 
      953X TO VERSION 955X. TO DETERMINE THE FIRMWARE LEVEL OF AN EXP100 
      ESM, IDENTIFY THE PRODUCT LABEL LOCATED AT THE REAR OF THE EXP100 
      ENCLOSURE. ONLY LABELS ON WHICH THE FIELD REPLACEABLE UNIT (FRU) 
      PART NUMBER READS 25R0156 POSITIVELY INDICATE THAT AN ESM MODULE IS 
      RUNNING FIRMWARE VERSION 955X OR HIGHER. IF THERE IS NO LABEL OR 
      THE PART NUMBER ON THE LABEL DOES NOT READ 25R0156, THE ESM MAY 
      STILL HAVE THE FIRMWARE VERSION 955X OR HIGHER IF IT HAD BEEN 
      PREVIOUSLY UPGRADED. IF NECESSARY, CONTACT YOUR IBM REPRESENTATIVE, 
      SUPPORT, OR RESELLER FOR ASSISTANCE.
       
   3. CURRENTLY, THE ONLY DS4000 STORAGE SUBSYSTEMS THAT ARE SUPPORTED 
      BY THE 06.1X.XX.XX CONTROLLER FIRMWARE VERSION ARE THE DS4100 
      WITH STANDARD OPTION, THE DS4300 WITH STANDARD OR TURBO OPTION, 
      THE DS4400 AND THE DS4500. DO NOT DOWNLOAD THIS CONTROLLER 
      FIRMWARE ON ANY OTHER DS4000 STORAGE SUBSYSTEM. THERE IS NOT 
      ANY CHECKING FOR THIS RESTRICTION INSIDE THE STORAGE MANAGER 
      CLIENT PROGRAM.
      
   4. THE DS4000 STORAGE MANAGER CLIENT PROGRAM VERSION 9.12.XX.XX OR 
      HIGHER MUST BE INSTALLED AND CONFIGURED TO MANAGE YOUR DS4000 
      STORAGE SUBSYSTEM. THIS PROGRAM IS INCLUDED IN THE APPROPRIATE 
      DS4000 STORAGE MANAGER VERSION 9.12 OR HIGHER HOST SOFTWARE 
      PACKAGES FOR THE OPERATING SYSTEM OF YOUR DS4000 MANAGEMENT 
      STATION. 
       
   5. If the managed DS4000 storage subsystem had the FC/SATA intermix 
      premium feature enable, do not upgrade the controller firmware 
      from version 06.10.xx.xx to version 06.12.xx.xx until a FC/SATA 
      intermix premium feature key file is generated and available. 
      Once the controller firmware is upgraded to version 06.12.xx.xx, 
      the FC/SATA intermix premium feature will be shown as 
      out-of-compliance and the FC/SATA intermix premium feature key 
      file is required to re-enable the feature. 
      When the FC/SATA intermix premium feature is in out-of-compliance 
      state, LUNs management functions like creations, deletions and 
      modifications will not be operational. Please refer to the FC/SATA 
      intermix premium feature activation card that was shipped with the 
      FC/SATA intermix premium feature kit for instructions to generate 
      the required premium key file.

   6. THE DS4000 STORAGE SUBSYSTEM WITH CONTROLLER FIRMWARE VERSION 
      05.41.1X.XX MUST BE UPGRADED TO CONTROLLER FIRMWARE VERSION 
      05.41.5X.XX FIRST BEFORE IT CAN BE UPGRADED TO CONTROLLER 
      FIRMWARE VERSON 06.1X.XX.XX OR LATER. OTHERWISE, THE ERROR 
      231-FIRMWARE INCOMPATIBLE WILL BE DISPLAYED. 


   IBM DS4000 Storage Manager host software version 09.1x.xx.xx provides 
   full management support for IBM machine types 3552 and 3542 storage 
   controllers that have at least firmware version 04.01.xx.xx 
   (05.xx.xx.xx in Microsoft Windows environment), IBM Machine type 1742-
   900 and 1742 storage controllers that have at least firmware version 
   05.00.04.xx or IBM Machine type 1722 storage controllers that have at 
   least firmware version 05.3x.xx.xx.
    
   The only IBM DS4000 Storage Manager version 09.1x.xx.xx supported 
   management function on controllers with non-supported controller 
   firmware versions is controller firmware and NVSRAM download. 

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

2.0   Change History
-----------------------------

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

2.1   Version History
-----------------------------

This is the latest release of IBM DS4000 TotalStorage™ controller 
firmware/NVSRAM for the following DS4000 storage subsystem models - the 
DS4100 with Standard option, the DS4300 with Standard or Turbo options, 
the DS4400 and the DS4500.

Version 06.12.10.00, 09/19/2005 for the DS4100 with Standard option, 
 the DS4300 with Standard or Turbo option, the DS4400, and the DS4500
     
    - 85533 (85265, CMVC 265068, 29644) Problem: Media scan is running 
            only on the even number LUNs. DACstore scrub loops with 
            media scan enabled on one LUN.
            Fix: To insure scrub flags are cleared, the controller 
            that gets first opportunity to clear the flags will clear 
            all scrub flags.
    - 90277 (90179, CMVC 275409) Controller lock down due to PCI errors.
            Fix: Function changes within error handling of PCI SERRs.
    - 89192 (88852, CMVC 266827) Problem: Mode sense for caching pages 
            (page 8) did not comply with the SCSI-3 specification. 
            Fix: Changed data returned for these commands to conform 
            with the specification by increasing the data from 12 to 
            20 bytes and initializing the data values appropriately.
    - 86207 (85917, CMVC 266752) Problem: excessive e-mail notification 
            messages for a single HDD failure. 
            Fix: Break out of loop after posting MEL event so event 
            will not be posted multiple times
    - 86640 (86452, CMVC 266203) Problem: Storage Manager showing 
            "Needs attention" indicator for an offline drive. No entry 
            in recovery guru for this condition. 
            Fix: Prevent the "needs attention" indication from being 
            set unless the offline drive has at least one piece defined 
            for it.
    - 87278 (86913, CMVC 270899) Unreadable sectors on logical drive 
            repaired.
    - 88137 (88091, 88430, CMVC 279189) DS4100 firmware. 
             Problem: excessive printfs recorded 
             for each error on native SATA drives.  These printfs can 
             cause timeouts on I/Os issued to SATA drives in EXP100 
             expansion drawers. 
             Fix: Only call sataDumpCDB and sataDumpRegs if sataIoDebug 
             variable is set.
    - 86335 (85820, CMVC 267254) MDISK OFFLINE. Problem: Controller is 
             attempting to fail a drive and attempting to suspend 
             volume activity only it can't get the alternate controller 
             to quiesce. The controller will continue forever to 
             attempt to do this until successful.  
    - 88210 Fixed DS4100 NVSRAM FLC bit changing from 0x82 to 0x81 
            when upgrading from 05.42.x
    - 88195 (88120) Problem: Controller does not finish SOD. 
            Fix: LockMgr change to role negotiation left lockMgr 
            in an partially uninitialized state.
    - 89079 Implement lock in cmdRelease to prevent release commands 
            from being processed while reserve commands are blocked.
            Move the point at which the lock is taken in cmdReserve 
            to a point just above where the lunInfo is initialized.  
            This will prevent stale data if the command is blocked.
    - 87892 (86968) Fixed a unchecked memory access with multiple drives, 
            controllers and drives being taken off/online. 
    - 87842 Problem: Both controllers reboot during/after an ESM download.  
            Fix: Change timeout with Cache Recover code (vdCacheRecover) 
            hogging the CPU so that the watch dog timer could not be reset.
    - 86495 (86424) Fixed an 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. 
    - 85652 (76791)Prevent potential concurrent volume ownership by 
            two controllers using the DacstoreAccess locking mechanism 
            during SOD.
    - 88802 Fix loss of drive signing data in NVSRAM on DS4100 ugrade 
            from firmware 05.42 to 06.12.
    - 86998 Modified the 400GB SATA drive command timeout from 8 seconds 
            to 180 seconds during drive firmware download. 
    - 87335 (87075, 86996) Problem: Downloading drive firmware to a 
            ST3400832AS drive can take longer than the default ATA 
            Download timeout of 30 seconds.  For EXP100 expansion 
            drawers the default time allowed for an ATA Pass-Thru 
            Drive Firmware Download is fixed at 30 seconds.  
            If this time is exceeded, the SATA ESM will time out the 
            command and send a COMRESET to the drive, aborting the 
            download.  
            Fix: The APT_TIMEOUT value be changed to 60 seconds for 
            all controllers supporting EXP100 SATA.
    - 88693 (88617) Problem: Media Scan effectively disabled for 
            volumes at or near 2 Terabytes For RAID 5 volumes or 
            RAID 1 volumes greater than 1 TB. The media scan rate 
            calculation overflows and effectively disables media scan. 
            Fix: Change to use 64 bit math in cfgSetLunScrubRate.
    - 87782 (87720, 86427) Problem: Ancient I/O (mode select I/O) 
            occuring during stress tests. 
            Fix: Retry lockMgr master/slave negotiation if alternate 
            controller lockMgr had not been initialized.
    - 85341 (83408) Problem: Ancient I/O error when primary mirrored 
            pair volumes then change its synchronization settings from 
            automatic to manual synchronization. Placed that volume 
            group offline then back online. 
            Fix: Changed task switching logic so that if some task 
            voluntarily offers to preempt, and another task is waiting 
            then preempt that task and allow other tasks to run.
    - 86078 (85377, Caliber 05514) Implement Ancient I/O NVSRAM 
            programmable thresholds. By supporting (NVSRAM) programmable 
            thresholds, the controller firmware will allow IBM to 
            configure new values that help, in certain circumstances, 
            to reduce the number and frequency of Ancient I/O reboots.  
            This may benefit the upstream host systems in that it should 
            reduce the likelihood of a host-based multi-path driver 
            deciding to trigger fail-over actions due to the temporary 
            inaccessibility of the rebooting controller.
    - 87551 Problem: DS4500 controller hangs during SOD after being power 
            cycle or reboot. Dirty cache was not able to be recovered 
            properly, causing the  controllers to hang during SOD. 
            Fix: Problem was resolved by using a new variable for the 
            local RCB instead of reusing the variable for the global RCB.
    - 85069 (84406) Change for DS4300 to minimize, as much as possible, 
            the amount of CPU data cache thrashing that occurs when 
            accessing data structures in the I/O path.
    - 85541 (82793) Problem: Battery age is not updated when reading 
            the profile from the Storage Manager interface. 
            Fix: Force update of cfgGenerationNumber at least daily in 
            pollBattGNT so battery age will be updated at least daily.
    - 87026 (86609) Problem: Controller PANIC when inserting a drive 
            that contains invalid volume number. 
            Fix: Only call legacyVolumePresentEvent for valid volumes 
            in cfgCreateEventsOnFirstDriveIns to avoid panic in 
            evfWWN.h code for invalid volume number.
    - 85909 Storage Manager GUI loses communication with array
    - 85976 (80904) Problem: Unresponsive array from excessive MEL tasks. 
            Fix: Change to not log MEL entries for destination driver 
            errors or drive check conditions that are reported for 
            the same channel in a 2 second window.  Record channel 
            number in origin field of destination driver MEL event.
    - 86166 (86138, 75746) Problem: Ancient I/O (mode select I/O) 
            during stress I/O tests. 
            Fix: Retry lockMgr master/slave negotiation if alternate 
            controller lockMgr had not been initialized.
    - 86285 Problem: DS4100 controllers were manufactured with incorrect 
            Gold Key NVSRAM setting. 
            Fix: Read FLC during boot; if the value is 0x82 and the 
            inquiry string indicates either non-IBM OEM setting and 
            the controller is DS4100 then the appropriate default 
            setting will be applied (i.e. 0x81). 
    - 86391 Added  "special" cases of OEMs for which the NVSRAM Feature 
            Licensing Control byte in NVSRAM may need to be modified.
    - 88171 (84580) Problem: When running RLS diagnostics on the Storage 
            Manager client, if an ESM's preferred path and current path 
            usage differ, the ESM's physical location is reported under 
            the wrong channel in the dialog.  This was the result of 
            logic that would compare the path used to retrieve RLS 
            statistics against the current path used by the driver to 
            communicate with the ESM and change it to the alternate 
            value if they were not the same. 
            Fix: Substituted a call to ssmFindESMPort to determine the 
            correct slot location for the ESM in a given enclosure.
    - 88369 (88368, 81853) Problem: Client shows RLS negative numbers 
            or RLS data from the device displays the entire history for 
            that device, resulting in very large numbers. 
            RLS request issued to a device will not be able to retrieve 
            valid statistics.  
            Fix: Checks were added to hddRlsCopy to prevent it from 
            copying a timestamp to the RLS storage space.  
            This effectively invalidates the data for that RLS pass and 
            causes another RLS request to be sent.
    - 87067 (84954) Problem: Profile displays erroneous volume 
            configuration by incorrectly displaying which drives belong 
            to a volume. 
            Fix: Configuration management, the only resolution mechanism 
            available is to reduce the size of the window in which 
            incomplete information could be returned.  Change the return 
            value by setting a NULL Object Bundle pointer on a 
            getObjectGraph request received while a global variable 
            maintained by the HLM module indicating that SOD is in 
            progress is TRUE.
    - 85320 (81081, Caliber 05358) Fix for when an SFP is removed from 
            the system, the entire SFP object that represents the SFP 
            FRU/slot is dropped from the object bundle. 
    - 86045 (81853) Problem: RLS shows negative numbers. RLS from the 
            GUI  showed most of the drives as having large negative values 
            for all fields.  The others were 0. 
            Fix: If the data in LinkMonitor is invalidated, return null 
            values to the user call.
    - 86191 (86013) Problem: GHS drive may be dropped from the GHS list. 
            Fix: Changed cfgAddDacstore call such that we don't lose 
            track of the fact that a drive is a hot spare.

=======================================================================
        
2.4 Code levels at time of release are as follows
-------------------------------------------------

     1. Storage Controller Firmware versions:
        a. DS4500:  FW_06121000_06100500
        b. DS4400:  FW_06121000_06100500
        c. DS4300 Standard:  SNAP_288X_06121000          
        d. DS4300 Turbo   :  SNAP_288X_06121000
        e. DS4100 Standard:  SNAP_282X_06121000          
              
                                            
     2. Storage Controller NVSRAM versions:
        ATTENTION: The DS4000 storage subsystem controller firmware 
                   version 06.12.xx.xx uses the FC/SATA intermix 
                   premium key file to enable the FC/SATA intermix 
                   functionality. 
                   It does not rely on a certain version of the NVSRAM 
                   file like the controller firmware version 
                   06.10.xx.xx. 
                   Do not apply this version 06.12.xx.xx of the firmware 
                   until a FC/SATA intermix premium feature key file 
                   is generated and available.
                    
        a. DS4500:  N1742F900R912V06
        b. DS4400:  N1742F700R912V05

        c. DS4300 Standard:  N1722F600R912V05 
           (for EXP700/EXP710 ONLY attachment or when FC/SATA 
           intermix premium feature is enabled)

        d. DS4300 Turbo   :  N1722F600R912V05 
           for EXP700/EXP710 ONLY attachment or when FC/SATA 
           intermix premium feature is enabled)

        e. DS4100 Standard:  N1724F100R912V05 


        f. DS4300 Standard:  N1722F600R28enc2 (for EXP100 ONLY attachment)
        g. DS4300 Turbo   :  N1722F600R28enc2 (for EXP100 ONLY attachment)
        ATTENTION: DO NOT LOAD THIS NVSRAM FILE - N1722F600R18enc2 - 
         ONTO ANY OF THE DS4300 STORAGE SUBSYSTEMS THAT HAVE DRIVES 
         IN THE DS4300 CHASSIS DRIVE SLOTS. 
         THIS WILL CAUSE THE DS4300 storage subsystem NOT RECOGNIZING 
         ANY OF THE DRIVES IN THE DS4300 CHASSIS. 
         THIS COULD RESULT IN THE DEGRADATION OF THE DEFINED RAID 
         ARRAY OR A LOSS OF ACCESS TO DATA. 
         IF THIS NVSRAM FILE IS LOADED INTO A DS4300 storage subsystem 
         WITHOUT ANY DRIVE EXPANSION ENCLOSURES ATTACHED, 
         IT WILL PREVENT THE storage subsystem FROM COMPLETING THE 
         BOOT PROCESS THAT IS INITIATED TO ACTIVATE THE NEW NVSRAM 
         SETTINGS, WHICH MIGHT RESULT IN LOST OF MANAGEMENT ACCESS TO 
         the DS4300 storage subsystem. THERE IS NO SAFETY MECHANISM 
         TO PREVENT THE UNINTENTIONAL LOADING OF THIS NVSRAM FILE. 
         IN ADDITION, DO NOT USE THIS NVSRAM FILE IN THE DS4300 STORAGE 
         SUBSYSTEMS WITH FC/SATA INTERMIX PREMIUM FEATURE ENABLE.

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 DS4000 storage 
server controllers, the drive expansion enclosure ESMs and the hard drives 
in the DS4000 configurations before upgrading the controller firmware. 
Make any firmware updates as required BEFORE proceeding to upgrade the 
DS4000 controller with the firmware and NVSRAM files packaged with this 
README file. FAILURE to observer the minimum firmware requirement might 
cause your DS4000 storage subsystem 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 
     be updated to version 9326 or later before the 06.1x.xx.xx 
     controller firmware is downloaded into the DS4000 storage 
     subsystem controllers. 
     Otherwise, the installed drives in the EXP700 drive expansion 
     enclosures may not be displayed in the DS4000 subsystem management 
     window after the controller firmware is upgraded. 
     In addition, if the ESM firmware of any attached EXP100 drive 
     expansion enclosures must be at version 955x or higher before 
     updating the DS4000 storage subsystem controller firmware to 
     version 06.1x.xx.xx or higher.     
     
     To download drive expansion ESM firmware, do the following: 
   
     a.  Open the Subsystem Management window. 
     b.  Click Advanced => Download => Environmental(ESM) Card Firmware. 
         Follow the online instructions.
         
         Note: If the existing controller firmware in the DS4000 storage 
         server 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.
     
     Note: The latest ESM firmware versions for EXP100, EXP700 
     and EXP710 drive expansion enclosures are 9554, 9328 and 9631, 
     respectively.

3.2  If the managed DS4000 storage subsystem with controller firmware 
     version 06.10.xx.xx installed had the FC/SATA intermix premium 
     feature enable, do not continue with the next step until a 
     FC/SATA intermix premium feature key file is generated and 
     available. 
     Once the controller firmware is upgraded to version 06.12.xx.xx, 
     the FC/SATA intermix premium feature will be shown as 
     out-of-compliance and the FC/SATA intermix premium feature 
     key file is required to re-enable the feature. 
     When the FC/SATA intermix premium feature is in out-of-compliance 
     state, LUNs management functions like creations, deletions and 
     modifications will not be operational. Please refer to the FC/SATA 
     intermix premium feature activation card that was shipped with 
     the FC/SATA intermix premium feature kit for instructions to 
     generate the required premium key file. 
 

3.3  Important: You must install the firmware update prior to 
                downloading  the NVSRAM update. 
                Make sure that the firmware and NVSRAM file names match 
                the name listed section 2.4 for your particular DS4000 
                storage subsystem model.

     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.
       
3.4  (if applicable) Re-enable the FC/SATA intermix premium feature 
      using the premium key file.

3.5  After the controller firmware and NVSRAM is updated, consider
     checking the IBM TotalStorage™ Disk Storage Systems Technical 
     Support web site for the latest released hard drive firmware. 
     
     To download hard disk drive firmware, do the following: 
   
     a.  Schedule down time because the drive firmware upgrades require 
         that there are no HOST IOs to be sent to the DS4000 controllers.
     b.  Open the Subsystem Management window. 
     c.  Click Advanced => Download => Drive Firmware. 
         Follow the online instructions. 
         Note: with controller firmware version 06.1x.xx.xx or later, 
         multiple drives from up to four different drive types can be 
         updated at the same time. 
      

=======================================================================
                                
3.2  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 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
     and single controller configuration does not have the DS4000 
     storage partitioning premium enabled. Four partition, 
     eight partition, sixteen and an upgrade from four to eight 
     partition storage partitioning premium feature options can 
     be purchased. 

   - IBM DS4300 storage subsystem (machine type 1722): The standard and 
     single controller configuration does not have the DS4000 storage 
     partitioning premium enabled. Four partition, eight partition, 
     sixteen and an upgrade from four to eight partition storage 
     partitioning premium feature options can be purchased. The IBM 
     DS4300 with Turbo option comes with 8 partition storage partitioning 
     premium option installed. An upgrade to 64 partitions can be 
     purchased for the IBM DS4300 with Turbo option. 

   - IBM DS4400 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 DS4500 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. 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 subsystem serial ports 
   unless it is instructed by IBM Support. Incorrect use of the serial 
   port might result in lost of configuration, and possibly, data. 

4. 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 DS4000 storage subsystems DS4500, DS4400 and FAStT500 (IBM 
   machine type 1742 and 3552) have two ports per controller - one per 
   minihub slot. The DS4000 storage subsystems DS4300 (IBM machine 
   type 1722) and DS4100 (IBM machine type 1724) have two ports per 
   controller. 
   The DS4000 storage subsystem FAStT200 (IBM machine type 3542) 
   has only one port per controller.

5. All drive enclosures on any given loop should have complete unique 
   ID's assigned to them. For example, in a maximum configured DS4500 
   storage subsystem, enclosures on one redundant drive loop should 
   be assigned with ID's 10-17 and enclosures on the second drive 
   loop should be assigned with ID's 20-27. Enclosures ID's 00 ~ 09 
   should not be used and enclosure ID's with the same single digit 
   such as 11 and 21 should not be used on the same drive loop.    
     
6. 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.

7. IBM recommends at least one hot spare per EXP100 drive expansion 
   enclosure.
   A total of 15 hot-spares can be defined per DS4000 storage subsystem 
   configuration.
   
8. Starting with the DS4000 Storage Manager (SM) host software version 
   9.12 or later, the Storage Manager client script window looks for 
   the files with the file type of  ".script" as the possible script 
   command files. 
   In the previous versions of the DS4000 Storage Manager host 
   software, the script window looks for the file type ".scr" instead. 
   (i.e. enableAVT.script for 9.12 or later vs. enableAVT.scr for 
   pre-9.12)

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

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

1. By default the IBM DS4000 Storage Manager 9.12 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 9.12. 
   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 
   storage subsystems as boot devices, contact IBM support for supported 
   configurations and instructions for configuring LUNs in the IBM 
   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.
   
   - EnableAVT_W2K_S2003_noncluster.scr:  The script will enable 
     automaticlogical 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. 

   - disable_ignoreAVT8192_HPUX.script: This script will disable the DS4000 
     storage subsystem ignoring of AVT requests for the HP-UX server specific 
     read pattern of 2 blocks at LBA 8192. The AVT ignoring request for the 
     LBA 8192 reads was implemented to prevent a possible occurrence of an 
     AVT storm caused by the HP-UX server probing in the wrong order of 
     available paths to the volume(s) when it detect server to LUN path 
     failure. Use this script only when you do not have defined LVM mirrored 
     volumes using the mapped logical drives from the DS4000 storage 
     subsystems. Please contact IBM support for additional information, if 
     required.     
      
   - enable_ignoreAVT8192_HPUX.script: This script will enable the DS4000 
     storage subsystem ignoring of AVT requests for the HP-UX server specific 
     read pattern of 2 blocks at LBA 8192. The AVT ignoring request for the 
     LBA 8192 reads was implemented to prevent a possible occurrence of an 
     AVT storm caused by the HP-UX server probing in the wrong order of 
     available paths to the volume(s) when it detect server to LUN path 
     failure. Use this script only when you do have defined LVM mirrored 
     volumes using the mapped logical drives from the DS4000 storage 
     subsystems. Please contact IBM support for additional information, if 
     required.     
     
     
4. When you are configuring IBM machine type 1722, 1742 or 3552 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.
