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. 

New 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.

New 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
-----------------

   With this version 06.15.11.xx of controller firmware, the controllers in 
   the DS4800 storage subsystems (M/T 1815 models 82A/H, 84A/H) utilize all 
   of the available data cache memory installed in each controller blade for 
   I/O caching. Previously with controller firmware version 06.14.xx.xx, the 
   DS4800 controllers used only the first 1G bytes of the installed data 
   cache memory per controller for I/O caching.      

   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:
     
     - DS4800 storage subsystems 
     
     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. 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.
            
   2. The only DS4000 storage subsystems that are supported by the 
      06.14.xx.xx or 06.15.xx.xx controller firmware version are the DS4800. 
      Currently, there are not any controller firmware packages version 
      06.14.xx.xx or 06.15.xx.xx for other DS4000 storage subsystems besides 
      the DS4800. Do not download this controller firmware on any other 
      DS4000 storage subsystems.

   3. 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.

   4. 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.


   IBM DS4000 Storage Manager host software version 09.15.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, IBM Machine type 1722 storage controllers that have at 
   least firmware version 05.3x.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.

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.
     
     Note: The latest ESM firmware versions for EXP100 and EXP710
     drive expansion enclosures are 9554 and 9631, respectively.

	

3.2  Important: You must install the firmware update prior to downloading  
                the NVSRAM update.

     To download firmware, do the following: 
   
     a.  Open the Subsystem Management window. 
     b.  Click Storage Subsystem => Download => Firmware. 
         Follow the online instructions.

     To download NVSRAM, do the following: 
   
     a.  Open the Subsystem Management window. 
     b.  Click Storage Subsystem => Download => NVSRAM. 
         Follow the online instructions.
       
3.3  (if applicable) Enable the FC/SATA intermix premium feature using 
     the premium key file.

3.4  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. IBM DS4800 storage subsystem (machine type 1815): Depending on the 
   models, the 1815 storage subsystem is either shipped with 8 storage 
   partitions (model 82H/84H) or with a user selected 8, 16 or 64 storage 
   partitions model 82A/84A). 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.

2. 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. 

3. 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 DS4800 (IBM machine type 1815) has 4 ports per 
   controller.

4. All drive enclosures on any given loop should have complete unique ID's 
   assigned to them. For example, in a maximum configured DS4500 storage 
   server, 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.    
     
5. 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.

6. 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.
   
7. 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)

8. 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 9.15 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 9.15. 
   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 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. 

   - 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.

4.2 Unsupported configurations
------------------------------

   The following lists configurations that are currently not being 
   supported with IBM DS4000 Storage Manager 9.15.


   1. The DS4800 storage subsystem (machine type 1815 - all models) does
      not support the attachment of the FAStT EXP500 and DS4000 EXP700 (FC)
      drive expansion enclosures.   

   2. Fibre Channel loop environments with the IBM Fibre Channel Hub, 
      machine type 3523 and 3534, in conjunction with the IBM Fibre Channel 
      Switch, machine types 2109-S16, 2109-F16 or 2109-S8. In this 
      configuration, the hub is connected between the switch and the IBM 
      Fibre Channel RAID Controllers.

   3. The IBM Fibre Channel Hub, machine type 3523, connected to IBM 
      machine type 1722, 1724, 1742, 1815, 3542 and 3552.
   
   4. A configuration in which a server with only one FC host bus 
      adapter connects directly to any DS4000 storage subsystem with dual 
      controllers is not supported. The supported configuration is the 
      one in which the server with only one FC host bus adapter connects 
      to both controller ports of any DS4000 storage subsystem with dual 
      controllers via Fibre Channel (FC) switch (SAN-attached 
      configuration.)
