Problem Description: 

   This patch contains a Sun RSM Array 2000 RAID Controller firmware 
   update that fixes a bug with the inter-controller communication 
   mechanism. The problem manifests itself by issuing "ICON Chip failure" 
   messages (sometimes seen as ASC=03/ASCQ=00 codes in the 
   /var/adm/messages file).  

   In addition, the RAID Array Monitor daemon is being updated with 
   a version that corrects a problem with failovers not happening correctly
   on multi-RSM Array 2000 configurations.

Patch Installation Instructions: 
-------------------------------- 
Refer to the Install.info file for instructions on using the
generic 'installpatch' and 'backoutpatch' scripts provided with
each patch.  Any other special or non-generic installation
instructions should be described below as special instructions.

Special Install Instructions: 
----------------------------- 

  Firmware Update:
   Once the firmware file is loaded on the host system, the user must 
   manually update the firmware on both RSM Array 2000 controllers 
   found on each subsystem.  This process involves using the RAID 
   Manager application (started by running /usr/lib/osa/bin/rm6).
   When prompted for the name of the firmware file to use for the
   controller download, the following firmware file should be 
   specified:

			ap02041D.dl

   This file will be found in /usr/lib/osa/fw after this patch is been
   installed.  For further details on updating Sun RSM Array 2000 controller 
   firmware Refer to the RAID Manager User's Guide.

  Array Monitor Daemon Update:
   Once this patch has been installed, the 'arraymon' daemon will need to 
   be stopped and restarted.  This is accomplished automatically by the patch
   installation scripts.  Updating the firmware as described above is left as a 
   manual operation.
