Patch Installation Instructions:
--------------------------------
 
**************************************************************************
**WARNING:****WARNING:****WARNING:****WARNING:****WARNING:****WARNING:**
 
1)  The user is expected to:
 
	- back-up all important files before beginning the firmware upgrade
	- not disrupt the download process
 
    Any disruption during the download process can lead to unrecoverable
    damage to the disk.
 
2) Read this entire file and follow the instructions given below.

Special Install Instructions:
----------------------------
1) Log in as root on the system that needs the disk firmware upgrade
 
2) Back up all important files from the system
 
3) Unpack the patch (through tar) into any directory, say <patchdir>:
 
	# cd <patchdir>
	# tar -xvf <patch tar file>
 
   Note: If the patch ends in a ".Z" suffix, you will need to uncompress it.
 
4) Install IDE driver patch, 108974-15 (or greater)
 
5) Halt the system and bring it up in single user mode:
 
	# sync;sync;sync
	# /etc/halt
	ok> boot -s
 
6) In the patch directory, type the "flashdisk" command:
 
	# ./flashdisk -n <path_name>
 
   where <path_name> is dependent on the location of the disk. If the disk is 
	Primary Channel master  : <path_name> =  /dev/rdsk/c0t0d0s2
	Primary Channel slave   : <path_name> =  /dev/rdsk/c0t1d0s2
	Secondary Channel master: <path_name> =  /dev/rdsk/c0t2d0s2
	Secondary Channel slave : <path_name> =  /dev/rdsk/c0t3d0s2
 
 
NOTE: The download process can take up to 5 minutes.  Do not start any
      other process and avoid doing any operation on the system while 
      the download is in progress.  It is essential that you wait for
      for the command prompt before doing anything else.
 
      If the system has more than one disk, each disk needs to be
      updated seperately, followed by a reboot after each update.
 
      If there are two disks on the same channel, the following
      error message might be displayed in the console window
      when running the tool:
 
WARNING: timeout: early timeout chno = 0 targ = 0
 
WARNING: /pci@1f,0/pci@1,1/ide@3/dad@0,0 (dad0):
 	 ATA transport failed: reason 'timeout': retrying command
 
This is not a problem since the download process takes a long time
and the command to the other device might timeout in that period.
 
7) Shutdown the machine, power it off, power it back on, and reboot the
   system.
 
8) Confirm that the drive is now exhibiting the new firmware version by
   running the "iostat -E" command:
 
Example: % iostat -E
dad0     Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 
Model: ST39120A         Revision: 3.13     Serial No:             GG83 
.
.
.
    The firmware version is indicated in the "Revision:" field and after
    the update, it should show a value of 3.13.
