General information

Problem Fixed:

This new microcode level includes code changes to enhance long-term disk drive reliability.
 

Disk Drives Affected:

This microcode is for the following IBM SCSI hard disk drive:

  Size                         Model                  FRU # or             Assembly
                                                           FRU ASM#              P/N
----------------  -------------------   ---------------        ----------
 9.1GB (80 Pin)  DDYS-T09170M      07K7410            07K7408
18.2GB(80 Pin)  DDYS-T18350M      07K7406            07K7404
36.4GB(80 Pin)  DDYS-T36950M      07K7402            07K7400
 
 

Machines Affected:
All RISC/6000 and SP2 machine using these SCSI disk drives.
NOTE: The SP2 procedure requires copying microcode files to the appropriate SPOT(s). Therefore, it is highly  recommended that someone with an appropriate level of AIX experience and expertise performs the update, preferably the System Administrator or person(s) designated as responsible for making software updates to the system.
 

Operating System levels supported:

All levels of AIX that this product was announced on.
 

Determine the Drive Model, FRU&PN and Current Microcode level:

                a- SCSI Drives attached to SCSI Controllers(Not RAID)

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 SCSI hard disk:
lscfg -vl  hdisk16

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 ddysS9HA.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 ddysS9HA.bin

./ddysS9HA.bin

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

The directory ddysS9HAfw with these files will be added to /tmp/fwupdate.

DDYS-T0.524D3031.53394841
DDYS-T1.524D3031.53394841
DDYS-T3.524D3031.53394841
ddysS9HA.txt

Note: ddysS9HA.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/ddysS9HAfw/DDYS-T*  /etc/microcode

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

This will produce AIX backup diskettes. Label the diskettes:

" 2104  DDYS  Microcode Level  S9HA"
 

Microcode Download Procedure-SCSI Drives Attached to SCSI adapter-Non SP Systems

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 15 minutes

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 resource that microcode will be applied to(hdisk?) and PRESS ENTER.
6. Press "F7" to commit.

7. Make the following selections on the next screen:
    Select Input Device --------------------------------------- [ diskette]
    Microcode level to download ----------------------------- [ latest]
    Download latest level even if ------------------------------ [ yes]
    current is missing

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.
PRESS "F7" to commit

8. You will receive a msg. "Current Microcode is" and "Download has completed successfully"
       (this may take a few minutes)
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.

SCSI Disk Drive Microcode Download Procedure-SP systems
This procedure requires copying microcode files to the appropriate SPOT(s). Therefore, it is HIGHLY recommended that someone with an appropriate level of AIX experience and expertise should perform this task, preferably the System Administrator of person(s) designated as responsible for making software updates to the system.

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?
 NO. If the disk is part of rootvg or used as a paging device, microcode download can ONLY be performed while node is "Network Booted" into "Diagnostic Standalone Mode".

Is system reboot needed to activate the microcode: Yes

Installation Time: Installation time will vary depending upon the system configuration

Procedure for SP System (Nodes):

Note: Make sure that node on which work is to be performed has been "fenced" from the switch.
1. Obtain proper microcode diskette from from IBM Service Representative.
2. Copy microcode file from diskette onto CWS:
     restore -xvq
     (file will be copied into the "etc/microcode" directory)

3. Move microcode file from "etc/microcode" directory to the appropriate Spot(s) that are used by the customer for the node(s) to be updated.
    ie: /spdata/sys1/install/aix4??/spot/spot_aix4??/usr/lib/microcode                (??= level of AIX on your system)

4. To set the Node(s) to boot from network, from CWS, run command:
    spbootins -r diag [frame#] [node#] [node count]
    (example - - spbootins -r diag 1 13 1)

5. From Perspectives, perform a "Shutdown" for the node(s) to be updated.
6. From perspectives screen for node to be updated, select "Network Boot" and wait for TTY to open to DIAG MENU.
7. Choose "Task Selection".
8. Choose your terminal type.
9. Select "Download Microcode"
10. Select resource that microcode will be applied to(hdisk?) and PRESS ENTER.
11. Press "F7" to commit.
      (The current microcode level of the resource you selected earlier will be displayed at the top of the screen)
12.  In the "Select the input device" screen, make sure settings are as follows:

      Select Input Device --------------------------------------- [ disk]
      Microcode level to download ----------------------------- [ latest]
      Download latest level even if ------------------------------ [ yes]
      current is missing

PRESS "F7" to commit

13. You will receive a msg. "Current Microcode is" and "Download has completed successfully"
       (this may take a few minutes)

14. On CWS run the following command:
      spbootins -r disk [frame# [node#] [node count]

15. On CWS, After spbootins finishes, run the following command:
      splstdata -b (check output to see that node in question was set back to disk)

16. On "TTY" screen for node, Press F10 to get to "Shutdown Screen" and close TTY screen.
17. On perspectives screen of affected node, do a power off of the node and a power on of the node.
18. After node boots, telnet to the node, run the following command and check that correct microcode level has been updated.
          lscfg -vl hdisk# (ie hdisk0,hdisk1 etc)
