AIX Requirements:
For support:
AIX 5.1 ML_06 and above
AIX 5.2 ML_03 and above
AIX 5.3 ML_00 and above
Before you install the microcode, it is important to determine the microcode level of the Drive installed on the target system. Use the following instructions to read the Microcode Level.
1) List the optical drives attached to the target
systems by typing:
lsdev -Cc cdrom
2) To check the current microcode level for the optical
drive, enter the following command
lscfg -vl cdX
Where X is the number associated with
the optical drive listed as available in step 1.
Results of command
# lscfg -vl cd1

3) To check the current microcode level of the SCSI converter card follow these directions:
a) type in diag into the prompt
diag
b)
<enter> to continue to the next screen
c) arrow down to the Task Selection is highlighted and press
<enter>
d) arrow down to the Display Microcode Level is highlighted
and press <enter>
e) find the appropriate
optical drive, cdX, arrow down and highlight it. Then select it, by pressing <enter> and
then commit by press F7 key (commit function key can change, so read the bottom
of the screen to make sure the commit button is still F7 key).
f) select
SCSI Convert Card and press <enter>, and below is the result
DISPLAY MICROCODE LEVEL
cd1
The current microcode for the SCSI Converter Card
is ACA-SCSIDE16.174i.
This SCSI Convert Card has 174i microcode on it.
4.0.1 From the Web
The user should put the RPM file from the IBM website into
the /tmp directory.
The RPM file for this microcode update is called ibm-scsi-dvdram.rmbo0020301-I024.174i.rpm
Once the file is in /tmp directory, then to unpack the file
by executing following commands:
rpm -ihv
--ignoreos ibm-scsi-dvdram.rmbo0020301-I024.174i.rpm
The microcode files will be placed in the /etc/microcode/
directory.
The RPM packaged microcode files should be located in the
"/microcode/RPM"
If the user mounts the CD-ROM disc in the /mnt directory, then execute the
following commands to unpack the microcode.
cd /mnt/microcode/RPM
rpm
-ihv --ignoreos
ibm-scsi-dvdram.rmbo002031-I024.174i.rpm
The microcode files will be copied to "/etc/microcode".
Notes:
- "/etc/microcode" is a symbolic link to "/usr/lib/microcode".
- If permission does not allow the copy to the above stated directory
or file then the user will be prompted for a new location.
NOTE: Please save current and older versions of the
microcode update files in case you need to restore your system.
Please verify the file size and checksum of the raw microcode files in
/etc/microcode/.
To check file size, type these next two commands into the AIX prompt:
ls -l ACA-SCSIDE16.174i File size = 16384
ls -l IBM-RMBO002030.I024 File size = 1418240
To determine the checksum type these commands into the AIX prompt:
sum ACA-SCSIDE16.174i check sum = 09516
sum IBM-RMBO002030.I024 check sum = 40453
Procedure:
1. Stop all applications and un-mount any file system that is installed on the
drive. Media does not have to be removed
for the update process to take place.
2. Enter Diagnostics by typing the diag command into
the prompt
diag
3. The first screen tells you about Diagnostics. After reading this screen press <enter>
to continue
4. Arrow down to the Task Selection
is highlighted and press <enter>
5. Arrow down to the Download Microcode
is highlighted and press <enter>
6. Select all of the 16 Bit LVD SCSI DVD-RAM Drive that needs to be updated
from the list of devices by pressing <enter>. To commit to the next
step, Press "F7".
7. A dialogue box will be display a choice of updating DVD-RAM Drive or SCSI Converter
Card. Pick the down level, which should
have been determined back in process 3.0 Determining Current
Microcode Levels and press <enter> to continue. If both are down level, choose one and come
back after the process is complete and flash the other device.
8. Select "/etc/microcode" and press <enter>.
9. A dialogue box may display on screen if the /etc/microcode does not contain
the current microcode found on the device. This is just a warning screen
and if the microcode files have the same sum and file size as what is described
above, then the this process should work.
Also as a last resort, the drive will reject any corrupt microcode
trying to be loaded on it. Press
<enter> to continue.
10. An "M" will be displayed next to the latest level of microcode in
the /etc/microcode directory. Select that level and press <enter>.
11. The following message will appear on the screen when download is completed:
"Microcode download complete successfully. The current microcode level
for the device cd# is .....
Please run diagnostics on the drive to ensure that it is functioning
properly."
12. Sometimes it’s necessary to update both the SCSI Converter Card and
the Optical Drive, so don’t forget to update both those device if they
were down level.
13. Verify the microcode levels by repeating process 3.0
Determining Current Microcode Levels.
14. Run diagnostics to make sure the devices are in working order.
