=======================================================================
1.1  Limitations
---------------------
IMPORTANT:
The listed limitations are cumulative. However, they are listed by the 
DS4000 storage 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 versions 06.16.88.00, 06.16.92.00, 06.16.96.00, 
06.16.97.00 releases.

1. IBM Fibre Channel hard disk drives and SATA hard disk drives can not
   be intermixed inside the same DS4000 drive expansion enclosure. 

(For limitations in certain operating system environment, refer to the 
readme file that is included in the DS4000 Storage Manager host software 
package for that operating system environment.) 


Limitations with version 06.16.82.00 release.
None

Limitations with version 06.16.24.00 release.

1. Controller firmware 06.16.xx.xx does not support EXP100 storage expansion 
   enclosures. Do not download it into the DS4000 storage subsystems that have 
   EXP100 enclosures attached. After the 06.16.xx.xx controller firmware is 
   activated, the DS4000 storage subsystem will not recognize the drives in 
   EXP100 enclosures, causing loss of data availability to the RAID arrays 
   and logical drives that are defined in those drives. The DS4000 controller 
   firmware version 06.15.20.05 and earlier should be used in the DS4000 
   storage subsystems that have EXP100 drive expansion enclosures attached, 
   instead.

Limitations with version 06.15.20.05 release.

1. The following error message may be encountered under certain conditions
   when attempting to create a 2 TB LUN using the Create Logical drive 
   wizard in the Subsystem Management window:

    "Error 4 - The operation cannot complete because of an incorrect 
    parameter in the command sent to the controller."

   To avoid this error message, you must take certain steps while using the 
   Create Logical Drive wizard to create a 2 TB LUN.  Within the Specify 
   Capacity/Name window within the create logical drive wizard, you must not 
   manually specify the numeric value '2' in the New logical drive capacity 
   field in tandem with the "TB"  Units designator.  If you do this, the 
   Error 4 message will be issued and you will be unable to create the 2 TB 
   LUN. Click on the up or down arrows next to the input field to select the 
   desire capacity instead. When using the arrows, the program will display 
   the correct maximum logical drive capacity value that can be specified for 
   a given capacity unit (TB, GB, or MB). 

Limitations with version 06.15.15.xx release.

   There are not any limitations for controller firmware version 
   6.15.xx.xx. Please refer to the README files that are packaged with the 
   IBM DS4000 host software version 9.15 packages for various DS4000 
   support operating systems for host software related limitations.

Limitations with version 06.15.11.xx release.

   There are not any limitations for controller firmware version 
   6.15.xx.xx. Please refer to the README files that are packaged with the 
   IBM DS4000 host software version 9.15 packages for various DS4000 
   support operating systems for host software related limitations.

Limitations with version 06.14.19.xx release.

   There are not any limitations for controller firmware version 
   6.14.xx.xx. Please refer to the README files that are packaged with the 
   IBM DS4000 host software version 9.14 packages for various DS4000 
   support operating systems for host software related limitations.

=======================================================================
                
1.2  Enhancements

   The DS4000 storage subsystem controller firmware version 06.16.88.xx 
   and  06.16.9X.00 (in conjunction with DS4000 Storage Manager 
   9.16.xx.62 or higher) provides support for; 
    - DS4200 Express Storage Subsystem models 7VA/H, which support the
      attachment of DS4000 EXP420 Storage Expansion Enclosures. 
    - 500G SATA Enhanced Disk Drive Modules (E-DDMs) in the DS4000 
      DS4700 storage subsystems and the EXP810 Storage Expansion Enclosures.
    - 500G SATA Enhanced Value Disk Drive Modules (EV-DDMs) in the DS4000 
      DS4200 storage subsystem and the EXP420 Storage Expansion Enclosures.
   
   The corresponding change history file has more information on controller 
   firmware new features and updates.

   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
------------------

     NOTE: DS4000 storage subsystem controller firmware version 
           06.16.96.00, 06.16.97.00 requires Storage Manager 
           v09.19.xx.12 or higher package.

     The DS4000 controller firmware and NVSRAM file that are packaged 
     with this README file can ONLY be loaded in the following DS4000
     storage subsystems:
     
     - DS4700 storage subsystems with or without DS4000 EXP810/EXP710 drive
       expansion enclosures attached. 
     - DS4800 storage subsystems with DS4000 EXP810 and/or DS4000 EXP710 
       drive expansion enclosures attached. 
     - DS4200 storage subsystems with DS4000 EXP420 drive expansion 
       enclosures attached.        

     Note: Controller firmware 06.16.xx.xx does not support EXP100 drive 
     expansion enclosures.
          
     The IBM DS4000 Storage Manager host software version 9.16.xx.62 or
     higher is required to manage DS4000 storage subsystems with 
     controller firmware version 6.16.88.xx or 06.16.9x.00 are installed.

     IMPORTANT: DO NOT DOWNLOAD this controller firmware on any other DS4000 
     storage servers. 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. The only DS4000 storage subsystems that are supported by the 
      06.14.xx.xx, 6.15.xx.xx or 06.16.xx.xx controller firmware version are 
      the DS4800. Currently, there are not any controller firmware packages 
      version 06.14.xx.xx, 6.15.xx.xx or 06.16.xx.xx for other DS4000 storage 
      subsystems besides the DS4800. Do not download this controller firmware 
      on any other DS4000 storage subsystems. (Also see item #5 below)

   2. Always check the README files (especially the Dependencies section) 
      that are packaged together with the firmware files for any required 
      minimum firmware level requirements and the firmware download 
      sequence for the DS4000 drive expansion enclosure ESM, the DS4000 
      storage subsystem controller and the hard drive firmware.

   3. The DS4800 storage subsystems do not support the attachment of the 
      DS4000 EXP700 drive expansion enclosures. The EXP700 enclosure must 
      be upgraded into DS4000 EXP710 enclosure using the DS4000 EXP700 
      Models 1RU/1RX Switched-ESM Option Upgrade Kit before it can be 
      attached to the DS4800 storage subsystems.
      
   4. This version 06.16.xx.xx of the DS4200/DS4700/DS4800 controller 
      firmware is not compatible with the EXP100 SATA drive expansion 
      enclosures. DO NOT download it into the DS4800 storage subsystems 
      that have EXP100 drive expansion enclosures attached. After the 
      06.16.xx.xx controller firmware is activated, the DS4800 storage 
      subsystem will not recognize the drives in EXP100 enclosures, causing 
      loss of data availability to the raid arrays and logical drives that 
      are defined in those drives. The controller firmware version 
      6.15.xx.xx and earlier must be installed in the DS4000 storage 
      subsystems that have EXP100 SATA drive expansion enclosure attached 
      instead.

   5. Controller firmware 06.16.8x.xx or 06.16.9x.xx and higher is 
      required for the DS4200-all models, the DS4700-all models, and 
      the DS4800-model 80A/80H. 
      These models do not support older 06.16.xx.xx versions of controller 
      firmware. The attachment of EXP100 enclosures is not supported for these 
      models.
   
   6. Controller firmware 06.16.xx.xx is required to support EXP810 storage
      expansion enclosures.
      
   7. Controller firmware 06.16.88.xx and higher is required for attaching
      SATA Hard Disk Drives in the following configurations:
      a. Externally attached to the DS4800 through the IBM DS4000 EXP810.
      b. Internally attached to the DS4700 or externally attached through the 
         IBM DS4000 EXP810.
      c. Internally attached to the DS4200 or externally attached through the 
         IBM DS4000 EXP420.       
      

   IBM DS4000 Storage Manager host software version 09.16.xx.xx or higher 
   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, IBM Machine type 1722 storage controllers that 
   have at least firmware version 05.3x.xx.xx, IBM Machine type 1724 
   storage controllers that have at least firmware version 05.4x.xx.xx 
   or IBM Machine type 1815 storage controllers that have at least 
   firmware version 06.14.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. 

   
=======================================================================
        
1.5 Level Recommendation for the update
-----------------------------------------

     1. Storage Controller Firmware versions:
        a. DS4200: FW_DS4200_06169700
        b. DS4700: FW_DS4700_06169700
	  c. DS4800: FW_DS4800_06169700
           
        Note: The same firmware file can be used for upgrading the 
        controller firmware through the SMClient GUI or through the 
        controller serial port. Do not attempt to download the firmware 
        through serial port without the present of IBM Support personnel. 
        A botched controller firmware download via the serial port can 
        cause to the controller to be inoperable. 
                                            
     2. Storage Controller NVSRAM versions: 
        a. DS4200: N1814D420R916V01                   
        b. DS4700: N1814D470R916V17
        c. DS4800: N1815D480R916V13
       
      Note: The DS4000 storage subsystems that are shipped from the factory
            will show the NVSRAM version with a different first 
            character prefix than the "N" prefixed as stated. As long as 
            the rest of the version information after the first 
            character are the same, both the manufacturing NVSRAM 
            version and the "N" prefixed NVSRAM version are the same. 
            You do not need to update your DS4000 storage subsystem with 
            the  "N" prefixed NVSRAM version as stated above. For 
            example, the N1815D480R915V05 and M1815D480R915V05 (or 
            C1815D480R915V05 or D1815D480R915V05 or ...) versions are 
            the same because both versions share the same 
            "1815D480R915V05" string. The M1815D480R915V05 (or 
            C1815D480R915V05 or D1815D480R915V05 or ...) version was 
            loaded to the DS4800 storage subsystem at the factory. The 
            N1815D480R915V05 version is the one that was posted to the 
            DS4000 support web site for download.
            
            The prefix letter defines the number of partitions.
            A - 2 partitions
            B - 4 partitions
            C - 8 partitions
            D - 16 partitions
            E - 64 partitions

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.
     
     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.
     
   
3.2  Important: You must install the firmware update prior to downloading  
                the NVSRAM update. DO NOT proceed any further if you have any 
                EXP100 SATA drive expansion enclosures attached to the DS4800 
                storage subsystem that you are planning to upgrade the 
                controller firmware. This version of controller firmware is 
                not compatible with the EXP100 drive expansion enclosures. 
                After the 06.16.xx.xx controller firmware is activated, the 
                DS4800 storage subsystem will not recognize the drives in 
                EXP100 SATA drive expansion enclosures, causing loss of data 
                availability to the raid arrays and logical drives that are 
                defined in those drives. Contact IBM Support for help, if
                required.
                
               
     To download firmware, do the following:

     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 System Storage™ 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. IBM DS4200 storage subsystem (machine type 1814): Depending on the 
   ordering channels, the DS4200 storage subsystem is either shipped with 
   2 storage partitions or with a user selected 2, 4, 8, 16 or 
   64 storage partitions. If the DS4700 storage subsystem is ordered 
   with less than 64 partitions, various storage partition feature upgrade 
   options can be purchased to increase the maximum number of supported 
   storage partitions.

2. IBM DS4700 storage subsystem (machine type 1814): Depending on the 
   ordering channels, the DS4700-model 70 storage subsystem is either 
   shipped with 2 storage partitions or with a user selected 2, 4, 8, 16 or 
   64 storage partitions. Similarly, the DS4700-model 72 storage subsystem 
   is either shipped with 8 storage partitions or with a user selected 8, 
   16 or 64 storage partitions. If the DS4700 storage subsystem is ordered 
   with less than 64 partitions, various storage partition feature upgrade 
   options can be purchased to increase the maximum number of supported 
   storage partitions.

3. IBM DS4800 storage subsystem (machine type 1815): Depending on the 
   ordering channels, the DS4800 storage subsystem is either shipped with 
   an 8 storage partitions or with a user selected 8, 16 or 64 storage 
   partitions. If the subsystem is ordered with less than 64 partitions, an 
   upgrade from 8 to 16, 8 to 64 or 16 to 64 partition storage partitioning 
   premium feature option can be purchased.

4. 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. 

5. 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. The DS4700 (IBM machine type 1814) has up to 4 
   ports per controller. The DS4800 (IBM machine type 1815) has 4 ports per 
   controller. The DS4200 (IBM machine type 1814) has 2 ports per controller.

6. All enclosures (including DS4000 storage subsystem with internal drive
   slots) on any given drive loop/channel should have complete unique ID's,
   especially the single digit (x1) portion of the ID, assigned to them.
   For example, in a maximum configured 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. Enclosure id's with the same single digit such as 11, 21 and 31
   should not be used on the same drive loop/channel.
     
7. 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.

8. 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.
   
9. 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)

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

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

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

1. By default the IBM DS4000 Storage Manager 9.16 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 9.16. 
   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 NVSRAM, the 
      default host type is reset to Windows 2000/Server 2003 non-clustered 
      for DS4000 storage server with controller firmware version 
      06.14.xx.xx or later. For DS4000 storage server with controller 
      firmware version 06.12.xx.xx or earlier, it is reset to Windows non-
      clustered (SP5 or higher), instead.
              
   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 1814 or 1815 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 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. 

   - EnableAVT_Netware.script:  The script will enable automatic logical 
     drive transfer (AVT) for the Netware Failover heterogenous host 
     region. Do not use this script unless it is specifically mentioned in 
     the applicable instructions. 
  
   - DisableAVT_Netware.script:  The script will disable the automatic 
     logical drive transfer (AVT) for the Netware Failover 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 1814 and 1815 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.
