     1.1 Overview of this code

     The IBM FAStT Fibre Hard Disk and ESM Update Pack contains ESM and
     hard disk drive firmware updates for FAStT 200s, FAStT500s, FAStT600s, 
     FAStT700s and FAStT900s with EXP500s and EXP700s attached.

      The microcode(firmware) level for the EXP500 ESM is 9166.

      The microcode(firmware) level for the EXP700 ESM is 9326.

      FRUs are starting to ship with these levels of ESM Firmware.  If the 
      ESMs are not updated when the FRUs arrive at the higher level, the
      downlevel ESM will need updating at that time. 

      This release contains the following firmware for IBM Hard Disk Drives:

         Updating ESM firmware requires downtime (no host I/O) if the controller
         firmware level is 05.21 or lower.
         
         Updating Hard Disk Microcode requires downtime (no host I/O).

     1.3 Enhancements
         
         The Hard Disk Drive firmware updates in this release corrected the 
         following problems:
         - A drive would be marked offline when a lip was received on both ports.
         - The light for the drive would be lit green even if it failed an internal
           diagnostic.
         - Drives did not report the proper status when a correctable error was
           encountered.
         - Performance problem when the drive did queued sequential writes.


     1.4 Level of Recommendation

         IBM considers this update to be highly recommended for all customers.

         The 9166 ESM firmware is needed to prevent accidental corruption from
         downloading the wrong firmware to the ESM.  In environments where there
         are EXP500s and EXP700s on the same controller, it is IMPERATIVE that
         all EXP500s ESMs are updated to 9166 before the EXP700 ESM firmware
         is applied.

         The EXP500 and EXP700 ESM FRU replacements will also be updated to the
         current levels in this release (9166 and 9326 respectively), so if the
         surviving ESM in an EXP500 or EXP700 is not updated before the first 
         ESM failure, downtime must be scheduled to update it before the 
         replacement is inserted.  If the new ESM is installed before the 
         surviving ESM is updated, the FAStT controller will register a firmware
         mismatch and mark the replaced ESM failed or offline.  The EXP 
         enclosure will run, but long term operation with a mismatch is not
         recommended.  Customers who have updated to FAStT Storage Manager 8.3
         and firmware 05.30.xx.xx or higher can update ESMs online with no 
         downtime if both ESMs are functional.

         IBM strongly recommends applying both the HDD and ESM firmware at the
         next possible maintenance window.  

     1.5 Dependencies

         Before applying any hard disk drive or ESM updates, first update the
         FAStT TotalStorage Server NVSRAM/Firmware to the levels listed above 
         or higher.  FAStT 200, FAStT 500, FAStT 700, and FAStT 900 storage  
         controllers can be updated to the latest levels, Storage Manager 8.3
         or 8.4 for use with controller firmware 5.30.1X.XX.  The FAStT 600 can
         be updated to Storage Manager 8.33 or 8.4 for use with controller 
         firmware 5.34.0x.00.
         
         Be sure to follow the  list of prerequisites before updating.

            - For Hard Disk Drive firmware updates, ensure that all activity to
              the controller is stopped.

            - For ESM updates, all activity must be stopped if the controllers
              are at any firmware below 05.30.09.xx.

            - For ESM updates, all EXP500s need to be updated to 9166 before
              EXP700s can be updated to 9326.

2.0  Change History
___________________
      2.1 IBM FAStT Hard Disk and EXP500/700 ESM Update Program
          Version 1.41
          Updated EXP700 ESM Firmware to 9326 to correct memory corruption issue that 
          caused the ESM portname to change on the loop, resulting in I/O errors.
          The memory corruption was occurring when the ESM sent a response frame
          that didn't get taken off the loop for any reason and came back to it,
          which might happen if one of the ports on the ESM or controller tray were
          bypassed at the right time. This was fixed with new Vitesse libraries. 
          The new Vitesse libraries also fixed a problem where the Vitesse code was
          occasionally incorrectly removing some spawned tasks and preventing them 
          from firing, which was causing problems with loop diagnostics. There were 
          some additional changes to help make sure we report loop diagnostic failures
          correctly by adding retries to the code for turning on fault LEDs in case
          of temporary I2C failures. The new Vitesse libraries also fixed some issues
          we were seeing with unexpected LIPs on the loop under heavy I/O loads.


      2.2 IBM FAStT Hard Disk and EXP500 ESM Update Program
          Version 1.40
          Updated EXP700 ESM Firmware to 9324 to correct false fan and
          temperature errors, correct problems where the drives in bays 11-14
          would not spin up at power up, correct other drive side issues, 
          and provide support for copper GBIC cabling for use only with the 
          SAN Integrated Server.

          Updated EXP500 ESM Firmware to prevent accidental corruption from
          downloading the wrong firmware to the ESM.  In environments where 
          there are EXP500s and EXP700s in the same controller, it is IMPERATIVE
          that all EXP500s ESMs are updated to 9166 before the EXP700 ESM 
          firmware is applied.
          
          Updated firmware for drives with Strings ST318304FC, ST336704FC, and
          ST173404FC to B338; ST318452FC and ST336752FC to B94a; ST318432FC and 
          ST336732FC to B949; ST318453FC, ST336753FC and ST373453FC     to B954; 
          ST373307FC, ST336607FC and ST3146807FC to B356 to correct a problem 
          that caused the drive to marked offline when a lip was received on 
          both ports, corrected a problem where the light for the drive would
          be lit green even if it failed an internal diagnostic, corrected a 
          problem where drives did not report the proper status when a 
          correctable error was encountered, and corrected a performance 
          problem when the drive did queued sequential writes.

     2.3  IBM FAStT Fibre Hard Disk and EXP500 ESM Update Program
          Version 1.30
          Updated firmware for drives with ID strings of ST39103FC, ST318203FC,
          ST136403FC to B325; ST336605FC, ST373405FC to B346; ST318451FC,
          ST318452FC, ST336752FC to B946; ST318432FC, ST336732FC to B947 to
          correct a performance issue where the drives would recover slowly
          from Fibre Channel LIPs as well as mode page enhancements for better
          log reporting of drive activity. EXP500 ESM code is updated to 9166
          to improve bypass diagnostics when a bad GBIC is detected, correct an
          error where a HDD replacement is logged when an ESM is replaced,
          correct a condition where the ESM reports incorrect EXP component
          information, and protects the ESM from accepting incorrect firmware.

     2.4  IBM Fibre Hard Disk and EXP500 ESM Update Program
          Version 1.20
          Updated firmware for drives with product ID strings of
          ST318304F, ST336704F and ST173404F to B337, ST318451F
          to B933 as well as disable write cache on all drives to
          prevent drives from being failed by controller under extreme
          circumstances

     2.5  IBM Fibre Hard Disk Drive and EXP500 ESM Update Program
          Version 1.10
          Added update of EXP500 ESM Firmware from 9150 to 9163 to

4.0  Installation and Setup
___________________________
    
    4.1  Applying updates on FAStT controllers with 04.01.xx.xx or 05.2x.xx.xx
         firmware

         To apply ESM Updates use the IBM FAStT Field Tool v8.21.  See the 
         README included with that utility for directions on how to apply 
         updates. The utility can be found on the firmware update page at:

         http://www-1.ibm.com/support/docview.wss?uid=psg1MIGR-40120 
 
         Ensure that all activity to the controllers is stopped while performing
         ESM firmware updates with controller firmware 04.01.xx.xx or 
         05.2x.xx.xx. 
         
         Allow approximately 5-10 minutes per ESM to complete the firmware 
         update.
         
         This will require downtime.

    
    4.2  Applying updates on FAStT Controllers with 05.3x.xx.xx firmware or
         higher.

         To apply ESM updates use the FAStT Storage Manager Client 8.3 or 8.4, 
         See the on-line help included in the FAStT Storage Manager Client.

         Application of ESM firmware on FAStT Controllers with 05.3x.xx.xx 
         firmware or higher should be performed by choosing only one EXP at a time, 
         and done during non-peak utilization periods. 
         
         If you have a maintenance window with downtime, you can stop all I/Os and 
         update all the ESMs at one time.

         Allow approximately 5-10 minutes per ESM to complete the firmware
