1.0  Overview
_____________

     1.1 Overview of this code

      The IBM DS3000 EXP3000 ESM update contains ESM firmware updates for 
      the EXP3000 storage expansion enclosure.
     
      The microcode(firmware) level for the EXP3000 ESM is v01.74.

      IMPORTANT: This firmware update is supported with attachment of
      the IBM DS3000 EXP3000 to the DS3200 and DS3400 only.
      

     1.2 Limitations
                      
         The minimum DS3300 controller firmware levels for this update
         are:

         Model Type    						Firmware  

         1726 (21x, 22x, HC2)  		06.17.31.00 
	 			 1726 (41x, 42x, HC4)  		06.17.31.00        


     1.3 Enhancements
         
         See corresponding Change History document for more information.

     1.4 Level of Recommendation

         IBM considers this update to be recomended for all customers who
         attach the IBM DS3000 EXP3000 to a DS3200 or DS3400 storage
         subsystem.
         
         This update is not required to support attachment of a IBM
         DS3000 EXP3000 to a stand alone SAS RAID adapter.

         The IBM DS3000 EXP3000 ESM FRU replacements may be at a different
         ESM firmware version then the surviving ESM in an EXP3000. If the
         replacement ESM is not at the same ESM level as the surviving ESM, 
         downtime might need to be scheduled to update the ESMs after the 
         replacement is inserted. If a replacement ESM is installed and it
         has a different ESM firmware version then the surviving ESM, the 
         DS3000 controller will register an ESM hardware or firmware mismatch 
         error in the Recovery Guru. The new ESM will function; but long
         term operation with a mismatch ESM firmware in a EXP drive expansion
         enclosure is not recommend. Customers can update ESMs firmware 
         online via the IBM DS3000 Storage Manager v2.xx GUI management 
         software with no downtime if both ESMs are functional and ONLY ONE 
         EXP enclosure at a time is selected in the ESM firmware download 
         window for ESM firmware updating. CAUTION: Always check the 
         documentation of the applications that generate IOs to the storage 
         subsystem for any restrictions or prerequisites that will need to 
         be performed before performing concurrent ESM firmware downloads. 
         
         The new IBM DS3000 EXP3000 expansion enclosure supports automatic 
         ESM firmware synchronization. When you install a new ESM into an existing 
         EXP3000 that is attached to a DS3000 storage subsystem that 
         supports automatic ESM firmware synchronization, this feature 
         resolves firmware mismatch conditions by automatically 
         synchronizing the firmware in the new ESM with the firmware in the 
         existing ESM. To enable automatic ESM firmware synchronization:
         1. Verify that the DS3000 Storage Manager Event Monitor is 
            installed and running. 
         2. Verify that the DS3000 storage subsystem that the EXP3000 is 
            attached to is defined in the Enterprise Management window of 
            the DS3000 Storage Manager client.
         
 

     1.5 Dependencies

         IMPORTANT: Always check the DS3000 storage subsystem controller 
         firmware README for any required minimum version of the attached 
         drive expansion enclosure ESM firmware for that particular 
         controller firmware release. Update the ESM firmware using the 
         DS3000 Storage Manager software.
                  
         Be sure to follow the following list of prerequisites before 
         updating hard disk or ESM firmware.

            - If multiple storage expansion enclosures are selected for 
              ESM firmware updating at the same time, all IOs activity 
              must also be stopped. 

         
         If you are unsure about the sequence of firmware updates for 
         various components in the DS3000 storage subsystem configuration, 
         please call IBM Support at 1-800-IBM-SERV (1-800-426-7378) 
         before proceeding with the firmware upgrades. 

       
___________________________
2.0  Installation and Setup
___________________________    
  
    2.1  Applying updates on EXP3000 using the DS3000 Storage Manager v2.xx
         client.
         
         a) Go to the support tab in the Subsystem Management window 
            and select Firmware Download.
         
         b) Select the Download firmware link.
         
         c) Select Download Environmental (ESM) Card Firmware.
         
         d) Select the Drive enclosure(s) that are being updated.
         
         e) Select the correct ESM firmware file and select Start.

         NOTE: ESM firmware download should be performed by choosing 
         only one EXP3000 at a time, and done during non-peak utilization
         periods. 
        
         If you have a maintenance window with downtime and you can stop all 
         I/Os then you can update all the ESMs at one time.

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