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.

Note: 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 06.60.22.00 release.

1. Collect All Support Data may on occasion be incomplete.  Some files
   may be missing. Workaround is to recollect the data.

2. Unexpected Timeouts on EXP810 Expansion Drawers
   Problem or Restriction - 
      When you power up a storage subsystem that contains EXP810 expansion 
      drawers, the loop initialization protocols (LIPs) do not complete, with 
      the result that the expansion drawers time out and are not included in 
      the storage subsystem.   
   Workaround - 
      This problem is usually caused by having too many EXP810 expansion 
      drawers attached to one drive port on the controller module. There 
      should be no more than four EXP810 expansion drawers attached to one 
      port. If more than four EXP810 expansion drawers are in the storage 
      subsystem, connect four to one port, and the remaining expansion drawers 
      to the second port on the same channel.    
   Support Information - 
      CR 154265.

3. Empty Support Bundle File Generated
   Problem or Restriction -
      Following a controller failure, a support bundle file is automatically 
      generated, but the file is empty (file size = 0 Kb).
   Workaround -
      The support files can be manually collected and compressed by going to 
      the following directories:
          a. In Windows, go to <installdir>\client\data\monitor\tmpxxxxx  
          (where <installdir> is the directory specified at installation, and 
          tmpxxxxx is the temporary directory in which the files are stored).
          b.In a Unix-based operating system, go to /var/opt/SM/monitor/tmpxxxxx
          (where tmpxxxxx is the temporary directory where the files are stored).
          To ensure that the automatic generation feature remains enabled, the 
          Persistent Monitor should be restarted. To restart the Persistent 
          Monitor, follow the appropriate procedure below:
          • In Windows
            a Go to Windows Services >> Storage Array Event Monitor.
            b Double-click on the Persistent Monitor entry.
            c Click Stop.
            d Click Start.
            e Click OK and exit the Windows Services window.
          • In a UNIX-based operating system, use the command line interface to 
          enter the following sequence of commands:
            SMmonitor stop
            SMmonitor start
   Support Information - 
      CR 154448.

4. Disable autoSupportConfig Command Does Not Work
   Operating System - AIX
   Problem or Restriction
      Using the CLI command disable autoSupportConfig does not work.
   Workaround - 
      This feature is not supported in 10.50.
   Support Information - 
      CR 153601.

5. Logical Drive Creation Using the Script Editor Fails Syntax Verification
   Operating System - Windows 2003
   Problem or Restriction - 
      When using the script editor to create a logical drive, entering a logical 
      drive capacity of two digits (for example, 20Gb) results in a failure of 
      the “verify syntax,” and the logical drive is not created.
   Workaround - 
      The syntax requires a space between the digits and the unit of measure 
      for example, (20 Gb). Insert the space and the command should work.
   Support Information - 
      CR 152600.

Limitations with version 06.60.17.00 release.
None

Limitations with version 06.60.08.00 release.
none

Limitations with version 06.60.02.xx release.

1. RHEL5 on System p (Linux on Power) is not supported with this release.

2. Using In-Band Management with RHEL5 is not supported with this release.
   Out-of-Band Management must be used.

3. Linux on Power support of JS20 blades with QLogic fail-over driver is
   not supported at this time. (BZ 23360) 

4. SAN Boot on RHEL3 is restricted to initial root installation on Fibre
   Channel LUN ID 0. 

5. SAN Boot is not supported on IBM JS20 server blades with the initial
   release SLES 9 kernel.

6. SAN Boot is only supported on JS20 server blades with SLES9 w/SP1 and 
   above kernel. (6-3-2005) 

7. Storage Management software should not be installed on the ESX Server. 

8. Async RVM will only work at communication speeds of 10Mbytes or higher.



Limitations with version 06.23.05.00 release.

1. EXP500 and EXP700 storage expansion enclosures are not supported
   by this version of the controller firmware (6.23.xx). EXP700 storage 
   expansion enclosures can be upgraded to an EXP710s using the DS4000 
   EXP700 Models 1RU-1RX Switched-ESM Option Upgrade Kit before they are 
   recognized by the controller firmware version 6.23.xx. ATTENTION: DO 
   NOT DOWNLOAD this controller firmware version INTO THE DS4500 STORAGE 
   SUBSYSTEMS WITH EXP500S AND EXP700S OR DS4300 WITH EXP700S EXPANSION 
   ENCLOSURES ATTACHED. AFTER THE  CONTROLLER FIRMWARE VERSION 
   06.23.XX.XX IS ACTIVATED, THE DS4500 AND DS4300 STORAGE SUBSYSTEMS 
   WILL NOT RECOGNIZE THE DRIVES IN EXP700 AND EXP500 (FOR DS4500 ONLY) 
   ENCLOSURES, CAUSING LOSS OF DATA AVAILABILITY TO THE RAID
   ARRAYS AND LOGICAL DRIVES THAT ARE DEFINED IN THOSE DRIVES.
   Please note section 1.4 "Dependencies" for EXP700 supported controller 
   firmware levels.

2. Interoperability problem between the Tachyon DX2 chip in the DS4500 and
   the DS4300 storage subsystem controllers and the Emulex SOC 422 chip 
   in the EXP810 expansion enclosure ESMs causing up to 5 Fibre Channel 
   loop type errors to be posted in the DS4000 storage subsystem Major 
   Event Log (MEL) during a 24 hour period. There is a small window in 
   the SOC 422 chip that multiple devices can be opened at one time. 
   This ultimately leads to Fibre Channel loop errors of Fibre Channel 
   link up/down, Drive returned CHECK CONDITION, and Timeout on drive 
   side of controller. IBM recommends the use of the Read-Link-Status 
   function to monitor drive loop for any problems in the drive 
   loop/channel. There is no work-around.

3. The single digit of the Enclosure IDs for all enclosures (including the
   DS4000 storage subsystem with internal drive slots) in a given redundant
   drive loop/channel pair must be unique. For example, with four
   enclosures attached to the DS4300 storage subsystem, the correct
   enclosure ID settings should be x1, x2, x3, and x4 (where x can be any
   digit that can be set). Examples of incorrect settings would be 11, 21,
   31, and 41 or 12, 22, 32, and 62. These examples are incorrect because
   the x1 digits are the same in all enclosure IDs (either 1 or 2).

   If you do not set the single digit of the enclosure IDs to be unique 
   among enclosures in a redundant drive loop/channel pair, then drive 
   loop/channel errors might be randomly posted in the DS4000 subsystem 
   Major Event Log (MEL), especially in the cases where the DS4300 
   storage subsystems are connected to EXP810s and EXP100s. In addition, 
   enclosure IDs with same single digits in a redundant drive 
   loop/channel pair will cause the DS4000 subsystem controller to 
   assign a soft AL_PA address to devices in the redundant drive 
   loop/channel pair. The problem with soft AL_PA addressing is that 
   AL_PA address assignment can change between LIPs. This possibility 
   increases the difficulty of troubleshooting drive loop problems 
   because it is difficult to ascertain whether the same device with a 
   different address or a different device might be causing a
   problem.

4. DS4400, FAStT200 and FAStT500 subsystems, which are currently withdrawn
   from market, will not be supported by the controller firmware version
   6.23.xx.xx code thread.
   
5. During array and logical drive creation using SATA drive, it is 
   common to see Destination Drive Event reported in the MEL against the 
   drives being used in the array and logical drive. These events are 
   not indicative of a real problem but are the result of a limitation 
   in SATA technology at the present time.  So, when creating arrays and 
   logical drives using SATA drive, the Destination Drive Events being 
   reported against the drives being used in the creation of the array 
   and logical drive can be ignored. 
   
6. MEL Check Condition type b/88/1 is a vendor specific event that is 
   associated with SATA E-DDM drives.  This event is the result of some 
   other error.  If these events are present in the MEL, you should also 
   look for the presents of other drive error or check conditions to 
   identify the source of problem.  
   
7. If you are adding an EXP810 and attaching it to a EXP710 on the same 
   redundant drive loop channel, after upgrading ESM firmware to a 
   EXP810 that is attached to a EXP710 on the same redundant drive loop 
   channel, you may get a the following message in Recovery Guru.

   "Drive Enclosures Not Cabled Correctly"

   This is the result of a failed message between the EXP710 and EXP810 
   switched ESMs. The message informs another switched ESM that it is 
   attached to another switched ESM.  The controllers also use this 
   message to determine if storage expansion enclosures with switched 
   ESMs are clustered correctly, and what causes the Recovery Guru message.

   The workaround is as follows:

   a. Verify through DS4000 Storage Manager Client that there is no lose 
      of path redundancy to any of you storage expansion enclosures.

   b. Use the MEL to identify which storage expansion enclosures 
      (i.e.EXP710, EXP810) is reporting the incorrect cabling, as well 
      as which loop/channel (A side or B side).  When this occurs, you 
      will find a MEL Event 2835 for each affected enclosure.  Enclosure 
      and loop/channel identification are part of the event information.

   c. For each MEL event, for the Fibre Channel connection between the 
      enclosure (i.e. 810, 710) identified in the MEL event and the next 
      enclosure or controller (i.e. EXP810, EXP710, DS4800, DS4700, DS4200), 
      unplug the cable from the SFP on one side and plug it back in.

   d. Repeat until all connections between the enclosures mentioned in the 
      "Drive enclosures not cabled correctly" MEL have been unplugged and 
      plugged back in.  Note that a connection between a enclosure and the 
      adjacent enclosure/controller only needs to be unplugged/inserted once 
      at one end.    
      
8. With the release of 6.23.xx.xx controller firmware, when deleting a 
   volume that is part of a Remote Volume Mirror relationship, the 
   following steps are required before volume deletion:

   a. Disable Media Scan on the DS4000 Storage subsystem you are 
      deleting the volume from.
	
   b. Break remote mirror relationship associated with the logical drive
      or drives
 
   Once all volume deletion have been completed, re-enable Media Scan.
   Failure to perform these step may result in a controller reboot. 
   
9. When deleting volumes that are part of a array made up of SATA drives, 
   in some rare instances you may get an error message stating that the 
   volume deletion has failed. However, if you check further in the 
   Storage Manage GUI you will find that the volume was deleted.

10.SAN Volume Controller (SVC) customer are now allow to download ESM firmware 
   with concurrent I/O to the disk subsystem at controller firmware levels of
   6.23.05.xx or higher, with the following restrictions.

	1)  The ESM Firmware upgrade must be done on one disk expansion
            enclosure at a time.

	2)  A 10 minute delay from when one enclosure is upgraded to the 
            start of the upgrade of another enclosure is required.

   Confirm via the Storage Manager Application's "Recovery Guru" that the DS4000 
   status is in an optimal state before upgrading the next enclosure.  If it is
   not, then do not continue ESM firmware upgrades until the problem is resolved.       

11.Customer with IBM branded Hitachi FC drives should verify that these drives
   are at drive firmware FQ8, or later, before doing a controller firmware or 
   ESM firmware download.  It has been observed by IBM Support that customer's 
   with older versions of the Hitachi FC drive firmware have experienced failure 
   of these Hitachi drives during controller firmware and ESM firmware 
   downloads.
   Upgrading the drive firmware to FQ8 will prevent this problem.

	HUS103014FLF21      JFQ8                  (146G/10Krpm/2Gbps)

   To identify these drives you must view the Storage Subsystem Profile in the 
   Storage Manager Client.  Any drive NOT AT FQ8 should be upgraded to the FQ8 
   firmware level before attempting controller or ESM firmware upgrades.
  
12.IMPORTANT: EXP710 ESM FIRMWARE 9661 REQUIRES A MIMINUM DS4000 STORAGE 
   SUBSYSTEM CONTROLLER FIRMWARE LEVEL OF 06.12.40.00 OR HIGHER BEFORE 
   UPGRADING EXP710 ESM TO THIS LEVEL.


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

  
   The DS4000 Storage Manager version 9.60.xx.xx host software in conjunction 
   with controller firmware version 6.60.xx.xx provides supports for  

   - VDS/VSS Use new ability to recreate multiple snapshots. This is 
     associated with enhancement Recreate Multiple snapshots(see below).  
     The SMI-S providers will updated to use the new commands for 
     recreating multiple snapshots.
   - Recreate multiple snapshots. SYMbol addition of a re-create snapshot 
     command that will accept a list of snapshots as input.  This command 
     will be used by VSS and SMI-S providers to reduce the time needed to 
     re-create several snapshots at one time. 
     
   In addition, it also provides
     
   - Support for the new Daylight saving time as required by the enactment 
     of the United State's Energy Policy Act of 2005. The Daylight Saving 
     Time (DST) will begin at 2 a.m. on the second Sunday in March and 
     end at 2 a.m. on the first Sunday of November instead of 2 a.m. 
     on the first Sunday of April to 2 a.m. on the last Sunday of October. 
     For the year of 2007, DST will start on March 11, 2007 and end 
     on November 11, 2007. 
     
     DS4000 storage subsystem users in countries implementing the new 
     DST rules (which includes U.S., Canada, Bermuda) are recommended 
     to upgrade to Storage Manager version 9.19.xx.12 or later before 
     March 2007. Storage Manager version 9.19.xx.12 or later release 
     includes revised DST transition dates to comply with provision 
     of the Energy Policy Act of 2005 extension of Daylight Saving Time 
     (DST) by four weeks, beginning in 2007. 

     There are no data integrity or functional problems caused by an 
     incorrect clock setting. From the DS4000 controller firmware standpoint, 
     this change will have no impact. The software changes are in the Java 
     Runtime software included with the Storage Manager host software. The 
     DS4000 controller uses an internal time clock which is GMT time based. 
     The Storage Manager client software will make the appropriate time 
     changes for reporting the Major Event Log entries (MEL), subsystem 
     information or subsystem configuration changes in the time zone that the 
     management station is installed.
     
     If no updates are made to existing DS4000 Storage Manager host 
     software. The primary impact is that Email alerts and Major Event 
     Log (MEL) entries will be off by 1 hour for 3 weeks in the Spring 
     and 1 week in the Fall because they will be translated improperly 
     by the Java Runtime Engine that is currently in use.  This is a 
     cosmetic impact only; as noted above, all times within the DS4000 
     controller firmware are stored in GMT time. Such values will be 
     incorrect for the three-week period but then will be correct later 
     when viewed from DS4000 Storage Manager client software. Additional 
     incorrect timestamps may be seen in diagnostic reports, various 
     subsystem component information displayed in dialog boxes, and 
     performance monitor.  

     In addition to updating the DS4000 Storage Manager host software, 
     additional operating systems patches may be needed for the host 
     server/management station that the DS4000 Storage Manager host 
     software is installed. This will ensure that no problems occur 
     with the implementation of the new DST rule. Please refer to the 
     support web site for your operating systems for more information. 
     Various impact scenarios are described below: 
    
    Host System      DS4000       Impact
    Operating        Storage  
    System           Manager

                                  to April 1, when the times are 1 
                                  hour earlier than the time in the 
                                  areas where the change is effective.

                                  stamps will be out of sync by 1:00 hour. 
                                  For example, a MEL event at 3:00 p.m. 
                                  on the system will be reported as 2:00 
                                  p.m. on the DS4000 MEL logs 
    Not Updated     Updated       Same as above, except the DS4000 Storage 
                                  Manager will report with the correct DST 
                                  time.
    Updated         Updated       Best scenario. Everything reports the 
                                  correct time 

   Please refer to the New Features section of the IBM DS4000 Storage Manager 
   version 9 Installation and Support Guide for Windows 2000/Server 2003, 
   NetWare, ESX Server, and Linux for additional information about the IBM 
   DS4000 Storage Manager version 9 enhancements.

     The IBM DS4000 Storage Manager host software version 10.36.x5.13 or 
     higher is required to manage DS4000 storage subsystems with controller 
     firmware version 6.60.22.xx installed.


     IMPORTANT: DO NOT DOWNLOAD this controller firmware on any other DS4000
     storage subsystem configuration that are not listed above. In addition
     to lost of access to the data in the storage subsystem that resides
     in the non-supported storage expansion enclosures, 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
-----------------

   The information in this section is pertinent to the controller firmware
   version 6.60.xx.xx release only. For the dependency requirements of
   previously released controller firmware versions, please consult
   the Dependencies section in the readme file that was packaged with each
   of those controller firmware releases.


   ATTENTION:

   1. Beginning in 2009, EXP700 expansion enclosures will be supported with 
      firmware levels 06.60.08.xx, 6.60.17.xx and 6.60.22.xx on all DS4300 
      and DS4500 machine types (all models except DS4300 SCU).        
      Supported ESM Firmware levels for intermix support:
          EXP 700  ESM = 9330
          EXP 100  ESM = 9566
          EXP 710  ESM = 9681
          EXP 810  ESM = 98C1
          EXP 810  ESM = 98C5 with 6.60.22.xx

   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 storage/drive expansion enclosure ESM, the
      DS4000 storage subsystem controller and the hard drive firmware.
      Certain versions of the controller firmware might require the storage
      expansion enclosures ESM be at certain version for the upgrade to be
      successful. In the same vein, a particular version of ESM firmware
      might require certain version of controller firmware to be installed     
      first before it can be download to the ESM.

   3. The only DS4000 storage subsystems that are supported by the
      controller firmware version 06.60.22.xx are the DS4200-all models, 
      DS4300 (dual-controller Standard/Base and Turbo models only), the 
      DS4500-all models, the DS4700-all models and the DS4800-all models 
      Currently, there are not any controller firmware packages version 
      06.60.22.xx for other DS4000 storage subsystems. Do not download 
      this controller firmware on any other DS4000 storage subsystems.

   4. The minimum EXP710, EXP100 and the EXP810 ESM firmware versions must
      be at or greater then 9663, 9566 and 98A3, respectively.

   5. The Fibre Channel drives in the DS4000 configuration must be loaded
      with the appropriate minimum drive firmware version as defined in 
      the hard drive and ESM firmware package version 1.59 found at the
      IBM support web site.


   6. Customer with IBM branded Hitachi FC drives should verify that these drives
      are at drive firmware FQ8, or later, before doing a controller firmware or 
      ESM firmware download.  It has been observed by IBM Support that 
      customer's with older versions of the Hitachi FC drive firmware have 
      experienced failure of these Hitachi drives during controller firmware and 
      ESM firmware downloads. Upgrading the drive firmware to FQ8 will prevent 
      this problem.

      Hitachi FC Product IDs supported in DS4000 Storage Subsystems:

    	HUS103009FLF21      JFQ8                  (9G/10Krpm/2Gbps)
    	HUS103018FLF21      JFQ8                  (18G/10Krpm/2Gbps)
    	HUS103036FLF21      JFQ8                  (36G/10Krpm/2Gbps)
    	HUS103073FLF21      JFQ8                  (73G/10Krpm/2Gbps)
    	HUS103030FLF21      JFQ8                  (300G/10Krpm/2Gbps)
    	HUS103014FLF21      JFQ8                  (146G/10Krpm/2Gbps)

      To identify these drives you must view the Storage Subsystem Profile in 
      the Storage Manager Client.  Any drive NOT AT FQ8 should be upgraded to 
      the FQ8 firmware level before attempting controller or ESM firmware 
      upgrades.
  
   7. IMPORTANT: EXP710 ESM FIRMWARE 9661 REQUIRES A MIMINUM DS4000 STORAGE 
      SUBSYSTEM CONTROLLER FIRMWARE LEVEL OF 06.12.40.00 OR HIGHER BEFORE 
      UPGRADING EXP710 ESM TO THIS LEVEL.


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

Note: For controller firmware version 6.60.xx.xx code thread, the DS4300
dual-controller standard/base model share the same firmware and NVSRAM
files an the DS4300 dual-controller Turbo model.

     1. Storage Controller Firmware versions:

        a. DS4200:                 FW_DS4200_06602200
        b. DS4300 dual-controller: FW_DS4300-dualControllers_06602200
        c. DS4500:                 FW_DS4500_06602200
        d. DS4700:                 FW_DS4700_06602200
        e. DS4800:                 FW_DS4800_06602200 

        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 presence of IBM Support personnel.
        A botched controller firmware download via the serial port can
        cause a controller to become nonfunctional.

     2. Storage Controller NVSRAM versions:
         
        a. DS4200: N1814D420R960V05.dlp
        b. DS4300 dual-controller: N1722F60R960V0AF.dlp 
           Use this level of NVSRAM for:
           * DS4300 installed without drive expansion enclosures. 
           * DS4300 configured with only Fibre Channel drive expansion 
             enclosures attached. 
           * DS4300 with the FC/SATA intermix premium feature.
             Feature which enables intermix support of EXP700/EXP710.
           * DS4300 with EXP710/EXP810 drive expansion enclosures
             (either Fibre Channel or SATA drives installed in EXP810) 
             and EXP100 SATA drive expansion enclosures.   

        c. DS4300 dual-controller: N1722F60R960V0AS.dlp 
           Use this level of NVSRAM for:
           * DS4300 installed with SATA ONLY disks installed in EXP100 
             or EXP810 expansion disk drive enclosures.
        d. DS4500: N1742F900R960V05.dlp    
        e. DS4700: N1814D470R960V05.dlp
        f. DS4800: N1815D480R960V05.dlp    
               
           ATTENTION: 
           THERE IS NO SAFETY MECHANISM TO PREVENT THE UNINTENTIONAL 
           LOADING OF THIS NVSRAM FILE. 
           
           1. DO NOT LOAD NVSRAM FILE (N1722F60R960V0AS.dlp) ONTO DS4300 
           WITH FIBRE CHANNEL DRIVES INSTALLED IN INTERNAL CHASSIS. 
           THIS IMPROPER ACTION WILL RESULT IN:
           * LOST CONFIGURATION FOR NEWLY INSTALLED DRIVES OR FOR 
             DRIVES THAT MAY HAVE BEEN PREVIOUSLY CONFIGURED.
           * DEGRADATION OF DEFINED RAID ARRAY OR LOSS OF ACCESS TO DATA. 
           
           2. DO NOT LOAD NVSRAM FILE (N1722F60R960V0AS.dlp) ONTO DS4300 
           WITHOUT ANY DRIVE EXPANSION ENCLOSURES ATTACHED
           THIS IMPROPER ACTION WILL RESULT IN:
           * DS4300 NOT COMPLETING BOOT PROCESS WHICH INITIATES THE 
             ACTIVATION OF NEW NVSRAM SETTINGS
           * LOSS OF STORAGE MANAGEMENT ACCESS TO DS4300. 
           
           3. DO NOT USE THIS NVSRAM FILE (N1722F60R960V0AS.dlp) 
              WITH DS4300 WHICH HAS FC/SATA INTERMIX PREMIUM FEATURE 
              ENABLED.


      Note: The DS4000 storage subsystems shipped from the factory
            may have NVSRAM versions installed with a different first 
            character prefix. Both 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 N1815D480R923V08 and 
            M1815D480R923V08 (or C1815D480R960V03 or D1815D480R960V03 or ...) 
            versions are the same. Both versions share the same 
            "1815D480R960V03" string value. 

   Refer to the following IBM System Storage™ Disk Storage Systems
   Technical Support web site for the latest released code levels.

      being upgraded.


The sequence for updating your DS4000 Storage Subsystem firmware may be 
different depending on whether you are updating an existing configuration, 
installing a new configuration, or adding drive expansion enclosures. 

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. The order in which you will need to upgrade firmware
levels can differ based on prerequisites or limitations specified in these 
readme files. If no prerequisites, or limitations, are specified, the 
upgrade order refered in section 2.1 Installation For and Existing
Configuration should be observed. 

If drive firmware upgrades are required, down time will need to be scheduled. The 
drive firmware upgrades require that there are no Host I/Os sent to the 
DS4000 controllers during the download.

Note: For additional setup instructions, Refer to the Installation, User's 
and Maintenance guide of your DS4000 storage subsystem or storage expansion 
enclosures.


2.1   Installation For an Existing Configuration
-------------------------------------------------

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. The order in which you will need to upgrade firmware
levels can differ based on prerequisites or limitations specified in these 
readme files. If no prerequisites, or limitations, are specified, the 
upgrade order refered in section should be observed.

 1.  Upgrade the storage manager client program to the latest storage 
     manager 10.36.x5.13 version that is available from the DS4000 system 
     storage support web site. Older versions of the storage manager client 
     program will show that the new firmware file is not compatible with the 
     to-be- upgraded DS4000 subsystem, even when the existing version of the 
     controller firmware installed in the DS4000 subsystem is of 6.60.xx.xx 
     code thread. 
     
     http://www.ibm.com/servers/storage/support/disk/
     
 2.  Make any hard disk drive and/or drive expansion enclosure ESM firmware 
     updates as required BEFORE proceeding to upgrade the DS4000 controller 
     with the firmware and NVSRAM files packaged with this README file. 
     FAILURE to observe the minimum firmware requirement might cause your 
     DS4000 storage subsystem to be OUT-OF-SERVICE. Check the IBM System 
     Storage™ Disk Storage Systems Technical Support web site for the latest 
     released hard drive firmware if you have not already upgraded drive 
     firmware to the latest supported version. (See 1.4 Dependencies) 
     
     To download hard disk drive firmware, do the following: 
   
     a.  Schedule down time because the drive firmware upgrades require 
         that there are no HOST I/Os to be sent to the DS4000 controllers.
     b.  Open the Subsystem Management window. 
     c.  Click Advanced => Maintenance => 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.  Update the firmware of the ESMs in the attached drive expansion 
     enclosures to latest levels before the upgrading the controller 
     firmware. (See 1.4 Dependencies)
     
     To download drive expansion ESM firmware, do the following: 
   
     a.  Open the Subsystem Management window. 
     b.  Click Advanced => Maintenance => 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: SAN Volume Controller (SVC) customer are now allow to
         download ESM firmware with concurrent I/O to the disk subsystem
         at controller firmware levels of 6.23.05.xx or higher, with the
         following restrictions.
	 1)  The ESM Firmware upgrade must be done on one disk expansion
            enclosure at a time.
	 2)  A 10 minute delay from when one enclosure is upgraded to the 
            start of the upgrade of another enclosure is required.
         Confirm via the Storage Manager Application's "Recovery Guru"
         that the DS4000 status is in an optimal state before upgrading the
         next enclosure.  If it is not, then do not continue ESM firmware 
         upgrades until the problem is resolved.

         Note: Reference IBM System Storage™ Disk Storage Systems 
         Technical Support web site for the current ESM firmware 
         versions for the drive expansion enclosures.

 	
 4.  Important: Install the Controller firmware update and Controller
                NVSRAM update at the same time using the option check box
                in the controller firmware download window. DO NOT proceed 
                any further if you have any EXP500 storage/drive expansion 
                enclosures attached to the DS4300 or the DS4500 storage 
                subsystem that you are planning to upgrade the controller 
                firmware. This version of controller firmware is not compatible 
                with the EXP500 drive expansion enclosures. After the 
                06.60.22.xx controller firmware is activated, the DS4300 
                or DS4500 storage subsystem will not recognize the drives 
                in EXP500 drive expansion enclosures, causing loss of data 
                availability to the raid arrays and logical drives that are 
                defined in those drives. 
                Please refer to the 1.4 "Dependencies" section for supported
                levels of controller firmware with EXP700 Enclosures.

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

3.0 Configuration Information
-----------------------------


3.1 Configuration Settings
--------------------------

1. By default, the IBM DS4000 Storage Manager 10.36 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 10.36.x5.13
   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 1742 or 1722 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 heterogeneous host region. The default setting is to
     disable AVT for this heterogeneous 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 heterogeneous 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 heterogeneous 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 heterogeneous 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 heterogeneous
     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.


3.2 Unsupported configurations

3.3  Helpful Hints
------------------
1. 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 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.  

   - 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.

   - 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.

   - 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.

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 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.

4. 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 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. Enclosure id's with the same single digit such as 11, 21 and 31
   should not be used on the same drive loop/channel.

   In addition, for enclosures with mechanical enclosure ID switch like
   DS4300 storage subsystems, EXP100 or EXP710 storage expansion
   enclosures, do not use enclosure ID value of 0. The reason is with the
   physical design and movement of the mechanical enclosure ID switch, it
   is possible to leave the switch in a “dead zone” between ID numbers,
   which return an incorrect enclosure ID to the storage management
   software. The most commonly returned enclosure ID is 0 (zero). In
   addition to causing the subsystem management software to report
   incorrect enclosure ID, this behavior also result in enclosure ID
   conflict error with the storage expansion enclosure or DS4000 storage
   subsystem intentionally set the ID to 0.

   The DS4200 and DS4700 storage subsystems and the EXP420 and EXP810
   storage expansion enclosures did not have mechanical ID switches. Thus,
   they are not susceptible to this problem. In addition, these storage
   subsystems and storage expansion enclosures automatically set the
   Enclosure IDs. IBM recommendation is not make any changes to these
   settings unless the automatic enclosure ID settings resulting in non-
   unique single digit settings for enclosures (including the storage
   subsystems with internal drive slots) in a given drive loop/channel.

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.
