DEVICE LOCATION DESCRIPTION
hdisk14 10-70-00-13,0 16 Bit SCSI Disk Drive (9100 MB)
Machine Type and Model......DGHS09U
ROS Level and ID.................30334530
a) Make a directory on an AIX system to receive the AIX format file.
Enter: mkdir /tmp/fwupdate
Note: If the directory /tmp/fwupdate already exists, make sure it is empty before proceeding.
b) Transfer the AIX format file to the /tmp/fwupdate directory (using "Save as ...").
You'll see the filename is dghs093e.bin
c) Unpack the file by executing the instructions below. You will be asked for the password from the license agreement.
Enter the commands:
chmod +x dghs093e.bin
[Don't overlook the periods (.) in the above command.]
The directory dghs093efw with these files will be added
Note: dghs093e.txt is a read me file(same as this file), it can be saved or printed for future use.
Enter the following command to copy the microcode files
to " /etc/microcode " directory :
cp /tmp/fwupdate/dghs093efw/DGHS09* /etc/microcode
Enter the following commands to copy these file onto a
ls /etc/microcode/DGHS09* | backup -i -v -f/dev/rfd0
This will produce AIX backup diskettes. Label the diskettes:
" DGHS09 Microcode Level 3E"
Warning: Do not power off the system or the drive during microcode download as this may permanently damage the disk drive
Caution: The microcode download process is nondestructive to the hard disks; however, as a precaution, ensure that a backup operation has been performed on the affected systems PRIOR to the microcode installation.
Can microcode be installed Concurrently?
If the disk is part of rootvg, microcode download can ONLY be performed in service mode using diagnostics CD. If disk is not part of rootvg, microcode download can be performed cuncurrently as long as drive is not in use.
Is system reboot needed to activate the microcode: Yes
Installation Time: Approximately 30 minutes CE Time; Approximately 15 minutes System Time
1. Properly shutdown the system.
2. Boot up the system in SERVICE mode with the CDROM diagnostics(Use diagnostics level 4.21 or above; It is recommended to use the same level of
Diagnostic CD as the AIX ).
3. Select the "Task Selection" from diagnostics menu.
4. Select "Microcode Download" from "Task Selection" menu.
5. Select hard disk drive (disk) that needs to be updated from the list of devices.
6. Select "diskette" as the Input device, Select "latest" as the Microcode level to download, Select "YES" to the question whether to download microcode even if present level is missing on the media (the diskette does not have the level that is loaded on the disk).
NOTE: A prompt will ask you to insert the microcode diskette into the floppy drive. Insert the diskette which accompanies these instructions. If this level is already installed in the drive you've selected a message will let you know. A message will also come up because the diskette does not have the previous level microcode on the diskette. This is true and is not required to complete the download. Hit enter to continue.
7- The following microcode files are included in the diskette:
FRU P/N Model
Microcode File Name
-------- ---------- -------------- ------------------------------
59H6816 59H692 DGHS-09U DGHS09U.A090061B.000203E0
8. The following message will appear on the screen when
download is completed: "The microcode download has completed successfully".
9. Return to the Tasks Selection menu and repeat this procedure for each hard disk that requires this microcode.
NOTE: The code takes effect immediately but VPD is not updated. ROS info will not indicate the change until the system is power cycled
10. Exit diagnostic and reboot system in normal mode.
