Machines
Affected: All RISC/6000 and SP2 machine using these SCSI disk drives.
SP2
NOTE: Some of these drives are used in RS/6000-SP2 systems, however, the
actual microcode file for SP systems are available only on internal IBM
database(CORE). You must obtain the necessary
files from your local IBM Service Representative. The SP2 procedure
requires copying microcode files to the appropriate SPOT(s). Therefore,
it is highly recommended that, while the IBM Service Representative
will provide the microcode, 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 these products were 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:

Diag
Select "Task Selection" from diagnostics menu.
Select "PCI RAID Physical Disk Identify"
Select SCSI RAID Adapter (press enter, then F7 to Commit)
This will display the Vital Product Data for Physical Diak drives attached to the RAID adapter.
If "Product Type" is DDYS , and ROM/RAM Fields are below S96F, then microcode of drive(s) need to be updated
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 ddys.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 ddys.bin
./ddys.bin
[Don't overlook the
periods (.) in the above command.]
The directory ddys
with these files will be added to /tmp/fwupdate.

d-Enter the following
command to copy the microcode files to " /etc/microcode " directory :
cp /tmp/fwupdate/ddys/DDYS*
/etc/microcode
e- Follow the procedure
below to copy these file onto diskettes:
Note:
Don't overlook the complete path of microcode files, microcode download
will
not work if files are not copied with complete path onto the diskette.
Diskette 1:
Enter command
ls /etc/microcode/DDYS-T0.*.53393646
| backup -ivf /dev/rfd0
This will produce
AIX backup diskettes. Label the diskettes:
" DDYS 9.1GB Microcode Level S96F"
Diskette 2:
Enter command
ls /etc/microcode/DDYS-T1.*.53393646
| backup -ivf /dev/rfd0
This will produce
AIX backup diskettes. Label the diskettes:
" DDYS 18.2GB Microcode Level S96F"
Diskette 3:
Enter command
ls /etc/microcode/DDYS-T3.*.53393646
| backup -ivf /dev/rfd0
This will produce
AIX backup diskettes. Label the diskettes:
" DDYS 36.4GB Microcode Level S96F"

Microcode Download Procedure-SCSI Drives Attached to SCSI adapter
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
resource that microcode will be applied to(hdisk?) and PRESS ENTER.
6. Press "F7"
to commit.
(The current microcode level of the resource you selected earlier will
be displayed at the top of the screen)
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)
