1.0 Microcode Change History:

IBM     RMBO0020511


This f/w improved the writing to 3x DVD-RAM media.


This f/w fixed a boot problem on 9117-570 systems which cause sys planar errors.  Also fix the problem of this drive not showing up in SMS during a boot.


Originally released microcode


2.0 AIX Requirements:


For support: AIX 5.2 ML_04 and above

            and AIX 5.3 ML_00 and above

3.0 Determine the Current Microcode Levels:

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

        Machine Type and Model......RMBO0020511

        ROS Level and ID............1.13

        Device Specific.(Z0)........058002028F000030                    



4.0 Downloading and Unpacking the RPM File to the Target Server

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-ide-dvdram.rmbo0020511-1.13.rpm


Once the file is in /tmp directory, then to unpack the file by executing following commands:
        rpm -ihv --ignoreos ibm-ide-dvdram.rmbo0020511-1.13.rpm

The microcode files will be placed in the /etc/microcode/ directory.

4.0.2 From the Microcode CD-ROM

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-ide-dvdram.rmbo0020511-1.13.rpm


The microcode files will be copied to "/etc/microcode". 


 - "/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.


5.0 Microcode Download Procedure for Optical Device

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-RMBO002051.1.13           File size = 1343928

To determine the checksum type these commands into the AIX prompt:
sum IBM-RMBO002051.1.13          check sum = 38400

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


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 Microcode Tasks and press <enter>.  (Older versions of the Diagnostic utility does not list Microcode Tasks as an option.  If this option is not listed, just skip this step and proceed to step 6. )


6. Arrow down to the Download Microcode is highlighted and press <enter>.

7. Select all of the IDE DVD-RAM Drive that needs to be updated from the list of devices by pressing <enter>. To commit to the next step, Press "F7".

8. Select "/etc/microcode" and press <enter>.

9. 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.

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. Verify the microcode levels by repeating process 3.0 Determining Current Microcode Levels.

13. Run diagnostics to make sure the devices are in working order.
