Document Revision History	Description
6/10/2010	Original README file
5/20/2011	Updated with Readme file

2.0 General information

This Readme file is intended to give directions on how to update the microcode found on the IBM SATA DVD-ROM Drive / DROM0020581

4.0 Machine's Affected:

8202-E4B, 8203-E4A, 8204-E8A, 8205-E6B, 8231-E2B, 8233-E8B, 8234-EMA, 8236-E8C, 8261-E4S, 9117-MMA, 9117-MMB, 9119-FHB, 9179-MHB and any newer systems

5.0 AIX Requirements:

For support: AIX 5.2 TL_10_SP04 and above

AIX 5.3 TL_6_SP04 and above

AIX 5.3 TL_7_SP01 and above

AIX 6.1 TL_0_SP02 and above

6.0 Determine the Current Microcode Level for AIX:

Before you install the microcode, it is important to determine the microcode level of the Drive installed in the target system. Use the following instructions to read the ROM level from the Drive.

1) List the CD/DVD Drives installed in the system by typing:

lsdev –Cc cdrom

2) To check the current microcode level for the drive or controller enter the following command

lscfg –vl cdX

Where “X” is the instance of the drive. The command will produce output similar to this:

# lscfg -vl cd1

cd1 U789D.001.DQD67B5-P4-D1 SATA DVD-RAM Drive

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

Machine Type and Model......DROMO0020581

ROS Level and ID............DA36

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

Part Number.................42R5292

EC Level....................H87201

FRU Number..................42R5292

Hardware Location Code...... U789D.001.DQD67B5-P4-D1

If the ROM Level is less than DA36 you should update the microcode.

7.0 Downloading the RPM Format File to the Target Server for AIX
Use this method to download to an AIX system:

NOTE: The instructions that follow are specific AIX commands. AIX commands are CASE (lower and upper) SENSITIVE, and must be entered exactly as shown, including filenames.

1) Make two directories on your AIX system to receive the RPM format file.
Enter: "mkdir /tmp/microcode"

and then create this directory

Enter: "mkdir /tmp/microcode/RPM"

2) Transfer the RPM format file to the /tmp/microcode/RPM directory (using "Save as ..."). Change to that directory, "cd /tmp/microcode/RPM".

You'll see the filename for the RPM file.
"rpm -ihv –-ignoreos IBM-DROM0020581.DA36.rpm”

3) For AIX: The microcode files will be added to /usr/lib/microcode/.

NOTE:
- "/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.

8.0 Discovery Tool Microcode CD-ROM creation and download instructions

To obtain information how to burn a CD-ROM and run the Discovery Tool for an AIX or Linux System please go to: http://techsupport.services.ibm.com/server/mdownload/CDROMhelp.html

1) After running the Discovery Tool successfully the "/tmp/microcode/RPM" directory was created and your rpm files are copied from the CD-ROM.

2) Change to that directory, "cd /tmp/microcode/RPM".

3) Unpack the file by executing the instructions below:
Enter the commands:
rpm -ihv –-ignoreos IBM-DROM0020581.DA36.rpm

4) Two microcode files will be copied to "/etc/microcode". The file size and checksum of the microcode image will be verified in Section 9.0.
            File Names:
             IBM-DROM0020581.DA36

9.0 Verifying microcode before download and notes for AIX

Please verify the file size and checksum of the raw microcode files matches what is listed below.

For AIX :
"ls -l /etc/microcode/ IBM-DROM00205081.DA36" to verify file size is 599168.
"sum /etc/microcode/ IBM-DROM00205081.DA36" to verify Checksum is 37232.

10.0 Microcode Download Procedure for AIX:

10.1 Downloading Microcode to the Drive

1) At the command line type “diag”
2) Select the "Task Selection" from diagnostics menu.
3) Select "Download Microcode" or "Microcode Tasks” then select “Download Microcode" from the menu.
4) Select all of the SATA DVD-ROM Drive that need to be updated from the list of devices by using the arrow keys to highlight the entry and pressing "Enter" to mark it. Press "F7" when you are done marking all the drives you want to flash.
5) Select "/usr/lib/microcode" or “/etc/microcode”.
6) A dialogue box may be displayed on screen. It will state that the current microcode level on the drive could not be found on the selected source. This is acceptable because the drive will reject any incorrect code. Press "Enter" to continue.
7) At this time, please remove media from the drive. If there is media present after the next step, the microcode download process will stop and a Warning message will appear, telling you to remove the media.
8) Select DA36 level and press "Enter" to flash the drive.
9) The following message will appear on the screen when download is completed: "Microcode download complete successfully. The current microcode level for the device cdX is ... Please run diagnostics on the drive to ensure that it is functioning properly."
10) If you selected more than one drive to update, then steps 6-10 will repeat until all drives are updated.
11) Exit diagnostics.
