SCSI Hard Disk Drive Microcode Download Procedure

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

Problem Fixed:
Fixes LED activity/access light in the (Ultrastar DDRS-34560W) 4.5GB, SCSI hard disk drives.  Amber LED should illuminate when motor is spinning.  In code Levels below S98G, amber LED illuminates only when drive is accessed (command active ).

Installation Time: Approximately 20 minutes if drive is part of rootvg(using Diagnostics CD); Approximately 5 minutes/drive if drive is not part of rootvg(using concurrent diagnostics).

Change History

Date	Microcode Level	Change Description
7/98	S98G	Fixed LED activity/access function light
6/98	Initial Release	--

Disk Drives Affected:

This microcode is for use in the following IBM 4.5 GB SCSI hard disk drive:

Part Number     FRU P/N           Model                 Microcode level     Description
------------        ----------          -------------          ----------------        ----------------------
03L5256            83h7105        DDRS-34560W     S98G                    4.5 GB SE (68 pin)

The microcode upgrade will bring up to the current level which is S98G.

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 4.5 GB SE SCSI hard disk:

lscfg -vl hdisk4

 DEVICE       LOCATION    DESCRIPTION

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 ddrs98g.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 ddrs98g.bin

./ddrs98g.bin

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

The directory ddrs98gfw with these files will be added to /tmp/fwupdate.
DDRS-34.52393041.53393847
ddrs98g.txt

Note: ddrs98g.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/ddrs98gfw/DDRS-34*  /etc/microcode

Enter the following commands to copy these file onto a diskette:
ls /etc/microcode/DDRS-34* | backup -i -v -f/dev/rfd0

This will produce AIX backup diskettes. Label the diskettes:

" DDRS-34560W Microcode Level S98G"

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 20 minutes if drive is part of rootvg(using Diagnostics CD); Approximately 5 minutes/drive if drive is not part of rootvg(using concurrent diagnostics).

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
--------        ----------         --------------      ------------------------------
03L5256    83h7105          DDRS-34560W    DDRS-34.52393041.53393847
 

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.
10. Exit diagnostic and reboot system in normal mode.
