SCSI Hard Disk Drive Microcode Download Procedure

=====================================================================================

General information

Problem Fixed:
Minor code fixes and enhancements,
1- Changes made in download to ensure compliance with Mode page settings.
2- Added new Inquiry page
3- Changes made so that format command work properly when drive has existing Glist(UEC 0117-NOID table build fail).
 

Disk Drives Affected:

This microcode is for use in the following IBM 9.1GB SCSI hard disk drive:

DASD P/N     FRU P/N      Drive Model   Microcode level                Description
------------       ----------      ------------        ------------------       ------------------------------------
59H6816       59H6926     DGHS-09U      3D or below          9.1GB Fast, Wide,Ultra Single Ended

The microcode upgrade will bring the disk drive to the latest level which is 03E0.

Machines Affected:

All RISC/6000 (all 70xx types), 7204 and 7131 machine types using these hard disk part numbers.

Operating System levels supported:

All levels of AIX that this product was announced on.

Determine the Current Microcode level:

To see the drive type and current microcode level, Execute the following command:

"lscfg -vl hdisk* |pg"

Example of the info on a 9.1GB Fast,Wide,Ultra,Single-Ended hard disk:
        DEVICE             LOCATION              DESCRIPTION
        hdisk14           10-70-00-13,0     16 Bit SCSI Disk Drive (9100 MB)
        Manufacturer.........................IBM
        Machine Type and Model......DGHS09U
        FRU Number.........................59H6926
        ROS Level and ID.................30334530
        Serial Number.......................681C590F
        EC Level...............................E31898
        Part Number..........................59H6816
        Device Specific.(Z0)..............000003029F00013A
        Device Specific.(Z1).............GAGSPR603E
        Device Specific.(Z2).............09RI
        Device Specific.(Z3).............98356
        Device Specific.(Z4).............0001
        Device Specific.(Z5).............22
        Device Specific.(Z6)..............E31777

If the data returned in the "Part Number" field matches the one listed above AND the value in "ROS Level and ID...." field is below  "30334530" , this microcode applies.  If this level is already installed then the "ROS Level and ID...."  shows:  "30334530".
Note: Drive microcode level is displayed in Hex value of ASCII charactors in VPD data. Each alpha-numeric ASCII charactor converts to a 2-digit hex
number.  For example in VPD displayed above, 30 Hex= ASCII chractor "0";  33 Hex= ASCII charactor "3" ; 45 Hex=ASCII charactor "E"; 30 Hex=ASCII charactor "0", therefore the microcode level is "03E0".

Downloading and Unpacking the Firmware Update Package From WEB

a) Make a directory on an AIX system to receive the AIX format file.

Enter: mkdir /tmp/fwupdate

Note: If the directory /tmp/fwupdate already exists, make sure it is empty before proceeding.

b) Transfer the AIX format file to the /tmp/fwupdate directory (using "Save as ...").

You'll see the filename is dghs093e.bin

c) Unpack the file by executing the instructions below. You will be asked for the password from the license agreement.

Enter the commands:

cd /tmp/fwupdate

chmod +x dghs093e.bin

./dghs093e.bin

[Don't overlook the periods (.) in the above command.]

The directory dghs093efw with these files will be added to /tmp/fwupdate.
DGHS09U.A090061B.000203E0
dghs093e.txt

Note: dghs093e.txt is a read me file(same as this file), it can be saved or printed for future use.

Enter the following command to copy the microcode files to " /etc/microcode " directory :
cp /tmp/fwupdate/dghs093efw/DGHS09*  /etc/microcode

Enter the following commands to copy these file onto a diskette:
ls /etc/microcode/DGHS09* | backup -i -v -f/dev/rfd0

This will produce AIX backup diskettes. Label the diskettes:

" DGHS09 Microcode Level 3E"

SCSI Hard Disk Drive Microcode Download Procedure

Warning: Do not power off the system or the drive during microcode download as this may permanently damage the disk drive

Caution: The microcode download process is nondestructive to the hard disks; however, as a precaution, ensure that a backup operation has been performed on the affected systems PRIOR to the microcode installation.

Can microcode be installed Concurrently?
If the disk is part of rootvg, microcode download can ONLY be performed in service mode using diagnostics CD. If disk is not part of rootvg, microcode download can be performed cuncurrently as long as drive is not in use.

Is system reboot needed to activate the microcode: Yes

Installation Time:  Approximately 30 minutes CE Time; Approximately 15 minutes System Time

Procedure:
1. Properly shutdown the system.
2. Boot up the system in SERVICE mode with the CDROM diagnostics(Use diagnostics level 4.21 or above;  It is recommended to use the same level of
    Diagnostic CD as the AIX ).
3. Select the "Task Selection" from diagnostics menu.
4. Select "Microcode Download" from "Task Selection" menu.
5. Select hard disk drive (disk) that needs to be updated from the list of devices.
6. Select "diskette" as the Input device, Select "latest" as the Microcode level to download, Select "YES" to the question whether to download microcode even if present level is missing on the media (the diskette does not have the level that is loaded on the disk).
NOTE: A prompt will ask you to insert the microcode diskette into the floppy drive. Insert the diskette which accompanies these instructions. If this level is already installed in the drive you've selected a message will let you know. A message will also come up because the diskette does not have the previous level microcode on the diskette. This is true and is not required to complete the download. Hit enter to continue.
7- The following microcode files are included in the diskette:

P/N              FRU P/N         Model              Microcode File Name
--------        ----------         --------------      ------------------------------
59H6816    59H692          DGHS-09U    DGHS09U.A090061B.000203E0
 

8. The following message will appear on the screen when download is completed: "The microcode download has completed successfully".
9. Return to the Tasks Selection menu and repeat this procedure for each hard disk that requires this microcode.

NOTE: The code takes effect immediately but VPD is not updated. ROS info will not indicate the change until the system is power cycled

10. Exit diagnostic and reboot system in normal mode.
