    1.0 Microcode Change History:

IBM     DROM00205


NR38

	
Improved DVD-RAM Reading


NR36

	
Added new features in configuration commands


NR30

	
Orinigal released microcode



2.0 AIX Requirements:

For support: AIX 5.1 ML_04 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

  cd1              P1/Q1-L0  IDE DVD-ROM Drive

        Manufacturer................IBM

        Machine Type and Model......DROM00205

    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 *dvdrom.slimide.NR38.rpm*

*
*

Once the file is in */tmp* directory, then to unpack the file by
executing following commands:
        *rpm -ihv --ignoreos dvdrom.slimide.NR38.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 dvdrom.slimide.NR38.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.

 


    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-DROM00205.NR38           *File size = 133364

To determine the checksum type these commands into the AIX prompt:
*sum** IBM-DROM00205.NR38          *check sum = 40166


*/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 <#3.0>.


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