1.0   Overview
--------------

1.1  Overview
-------------

This release includes the IBM FAStT Storage Manager storage controller 
firmware version 04.01.02.30 and updated NVSRAM files for IBM machine 
types 3526, 3542 and the 3552. (see section 2.2 below for NVSRAM changes).

The IBM FAStT Storage Manager version 7.10 Installation and Support 
Guide is available on IBM's Support Web Site as a downloadable Portable 
Document Format (PDF) file. (see Section 6.1 below).

1.2  Limitations
----------------

1. If you are upgrading controller firmware in IBM FAStT500 storage controller
   with 512MB Cache, you will have to stop I/O, wait until the controller cache
   flushed and reboot both controllers before upgrading firmware followed by 
   NVSRAM. You can reboot the controllers either by alternately placing the 
   controller offline and then online using the Storage Manager client program
   or by pressing the Reset button on both controllers. The Reset button is 
   located on the right of the indicator lights in the opening on the front of
   each controller unit. Follow the procedure listed below to alternately 
   placing the controller offline and then online:

   a. On a storage management station, start the Storage Manager client program
      and select a storage subsystem in the Enterprise Management Window.
   b. Select Tools -> Manage Device to open the Subsystem Management Window.
   c. In the Subsystem management window, right-click the "A" controller icon 
      and select Place->Offline. Click "Yes" in the Confirm Place Offline 
      window. A few(5) minutes later, the "A" controller will be held in reset
      (offline) state and have a red "X" over its icon in the Subsystem 
      Management window.
   d. Wait at least two minutes, right-click the "A" controller icon and select
      Place->Online. A few(5) minutes later, the "A" controller will be enable
      and have the red "X" remove from its icon. The time that the controller
      takes to come online depends on the number and the state of the hard 
      drives and logical drives defined in the storage subsystem. 
   e. To make sure that the "A" controller is seen by the Storage Manager 
      client program as online and optimal, right-click the "A" controller 
      and select "Properties". If the controller is online, a Properties 
      window for the "A" controller will be displayed without an intermediate 
      Error window. If there is an intermediate Error window, repeat this 
      step.
   e. Repeat steps c-e for the "B" controller.
   f. To redistribute logical drives between the controllers, select Storage
      Subsystem->Redistribute Logical Drives menu option. Click "Yes" in the
      confirmation window.
      
   To determine Storage Controller cache level, perform the following:

   a. On a storage management station, start the Storage Manager client program
      and select a storage subsystem in the Enterprise Management Window.
   b. Select Tools -> Manage Device to open the Subsystem Management Window.
   c. In the Subsystem Management window, either select Storage Subsystem->
      Profile (if the controller firmware was of 4.xx family) or select View->
      Storage Subsystem Profile (if the controller firmware was of 5.xx 
      family.) It may take a few minutes before the Storage Subsystem profile
      is displayed.   
   d. Under the Controllers heading, there is an entry that displays 
      information similar to the following example:

      Cache/processor size (MB):  256/32

   If this setting is listed as 512/32 you will need to arrange to perform this
   upgrade procedure at a time that you can stop I/O to the Storage Subsystem
   in order to ensure a successful firmware download and installation.

2. Storage Manager prompts you for a password if all hard disk drives 
   are removed from the storage subsystem.

   After removing all drives from a storage subsystem (or not powering on 
   drives and only the  controller), the IBM FAStT Storage Manager 
   software will prompt you for a password when trying to start the 
   software or trying to perform protected operations. Any password 
   entered will fail.

   Password information is stored on a reserved area of each hard disk 
   drive on the storage subsystem.  Each drive stores a mirrored copy of 
   the password data.  When there are no drives in the storage 
   subsystem, the storage management software does not find the password 
   data when you attempt password protected operations. Add one drive to 
   the storage subsystem and retry the operation.

3. Auto LUN/Array Transfer is not supported. If a controller fails over 
   arrays to the alternate controller and the failed controller is 
   replaced and brought back online, the arrays do not automatically 
   transfer to the preferred controller.  This must be done manually by 
   redistributing arrays.

4. Display issues when using 256 color settings. A brownish hash pattern 
   is displayed on the windows and in online help when running in 256 
   color mode.  Run the Storage Manager 7 application in a higher 
   display mode.

5. Error message Service Error 100 after installing Storage Manager 7.10 
   host-agent software. Causes of this include the following:

a. The host-agent software does not find any controllers at firmware 
   version 4.x. 

b. Controllers at firmware version 4.x have the access volume disabled 
   with NVSRAM configuration settings. 

c. NVSRAM on a controller in a storage subsystem that you are 
   attempting to manage has the access volume logical unit number (LUN) 
   set to a number that is already in use by another logical drive. 

d. NVSRAM on controllers in a storage subsystem that you are attempting 
   to manage contains an access volume LUN that is not supported by 
   operating systems and installed patches (for example, the access 
   volume is configured as LUN 31, but the operating system and service 
   packs only support 8 LUNs).
   

1.3  Enhancements 
-----------------
             
- Added Read Link Status Diagnostics support.
- Corrected NVSRAM to enable background media scan without redundancy check. 
  This setting is not changed on existing systems and must be enabled in the 
  Storage Manager Subsystem Management console.
  

1.4  Prerequisites 
------------------
        
  Microsoft Windows systems must update the device drivers for the IBM
  FAStT Host adapters and the IBM FAStT FC-2 Host bus adapters to the 
  8.1.4.60 driver version prior to updating the Firmware and NVSRAM for
  the FAStT subsystems to the 04.01.02.30 version.  

1.5  Dependencies
-----------------

   IBM FAStT Storage Manager version 7.10 and 8.2 requires IBM machine
   types 3526, 3542 and the 3552 storage controllers to have at least 
   firmware version 04.01.xx.xx.

  b. Click Storage Subsystem => Download => NVSRAM.
     Follow the online instructions.

3.2  Helpful Hints
------------------

1. The IBM FAStT Storage Manager will prompt you for a password if an 
   attempt is made to manage a storage subsystem where the FAStT RAID 
   Controller Unit does not have access to any hard disk drives. 
   
   This will occur even if no password has been setup.  
   
   The automatic discovery will discover each storage subsystem as two 
   separate storage subsystems.  
   
   To prevent this from occurring, ensure that at least one FAStT EXP500 
   Expansion Unit with at least one drive is properly attached to the 
   FAStT500 RAID Controller Unit in each storage subsystem that is being 
   managed. 
   
   Since the RAID controller unit should not be powered on until the 
   expansion units are attached and powered on, this should be done by 
   powering off the RAID controller unit, properly attaching all 
   expansion units (with drives installed), to the RAID controller unit 
   and powering them on, and then powering the RAID controller unit back 
   on.  At this point the storage subsystems can be re- discovered and 
   managed using the IBM FAStT Storage Manager 7.10 software.

2. If you are unable to see the maximum number of drives during 
   Automatic Configuration, you should be able to use Manual 
   Configuration to select individual drives and select the maximum 
   number of drives allowed.


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

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

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

1. By default the IBM FAStT Storage Manager firmware release does not 
   automatically map logical drives. 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.

   Refer to the IBM FAStT Storage Manager online help to learn more about 
   creating storage partitions and changing host types.

2. 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.

 - 3526CTLdual.scr: Enables the detection and error reporting for missing 
   or unresponsive controllers in a 3526 Dual RAID controller 
   configuration. If either RAID controller is removed or not 
   responding, it is detected and reported through the IBM FAStT Storage 
   Manager software. The 3526 NVSRAM default is enabled to detect a 
   missing or unresponsive alternate controller.

 - 3526CTLsingle.scr: This script disables the detection and error 
   reporting of the missing alternate controller in a 3526 single RAID 
   controller configuration.  After executing this script, the IBM FAStT 
   Storage Manager 7.10 software will not report the missing alternate 
   RAID Controller. The machine type 3526 NVSRAM default is enabled to 
   detect a missing alternate controller.

 - 3526EXPdualPS.scr: This script enables the detection and error 
   reporting of a missing or unresponsive alternate power supply in an 
   IBM Storage Expansion Unit configured with dual power supplies while 
   attached to the 3526. If either Storage Expansion Unit power supply 
   is removed or not responding, it is detected and reported through the 
   IBM FAStT Storage Manager 7.10 software. Machine type 3526 NVSRAM 
   default is enabled to detect a missing or unresponsive alternate 
   power supply in an IBM Storage Expansion Unit.

 - 3526EXPsinglePS.scr: This script disables the detection and error 
   reporting of a missing alternate power supply in an IBM Storage 
   Expansion Unit configured with a single power supply and attached to 
   the 3526. After executing this script, the IBM FAStT Storage Manager 
   7.10 software will not report the missing alternate power supply in 
   an IBM Storage Expansion Unit. The 3526 NVSRAM default is enabled to 
   detect a missing alternate power supply in an IBM Storage Expansion 
   Unit.
