2.0 AIX Requirements:
For support: AIX 5.1 ML_03 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
cd1 P1/Q1-L0 IDE DVD-ROM Drive
Manufacturer................IBM
Machine Type and Model......DROM00203
ROS Level and ID............7R43
Device Specific.(Z0)........058002028F000030

The user should put the RPM file from the IBM website into the /tmp directory.
The RPM file for this microcode update is called dvdrom.ide.7R43.rpm
Once the file is in /tmp directory, then to unpack the file by executing
following commands:
rpm -ihv
--ignoreos dvdrom.ide.7R43.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 dvdrom.ide.7R43.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 IBM-DROM00203.7R43 File size = 138260
To determine the checksum type these commands
into the AIX prompt:
sum IBM-DROM00203.7R43 check sum = 54659
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 IDE DVD-ROM Drive that
needs to be updated from the list of devices
by pressing <enter>. To commit
to the next step, Press "F7".
7. Select "/etc/microcode" and
press <enter>.
8. A dialogue box may display on screen if
the /etc/microcode doesn’t 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.
9. An "M" will be displayed next
to the latest level of microcode in the /etc/microcode
directory. Select that level and press
<enter>.
10. 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."
11. Verify the microcode levels by repeating
process 3.0 Determining Current Microcode Levels.
12. Run diagnostics to make sure the devices
are in working order.
