SUBJECT: IBM pSeries SCSI Enclosure Services for 7031-D24/T24
******* PLEASE READ THIS ENTIRE NOTICE *********
-If LPAR's exist, see the information in Section 5.0.
-7031-D24/T24 SES Microcode update can only be done via standalone or online diagnostics using AIX. If the microcode destination is a Linux partition then a AIX Standalone Diagnostic's CD will have to be used to perform the update. See Section 5.2 and 4.3 for information.
2.1
Installation Time:
Approximately 30 minutes
2.2
Machine's Affected:
7031-D24/T24
3.0 Determine the Current Microcode Level:
Before you install the microcode, it is important to determine the microcode level of the backplane installed in the target system. Use
the following instructions to read the ROS Level and ID stored in the backplane's VPD.
1) List the backplanes adapters installed in the system by typing:
lsdev -C | grep ses
Note: All of the backplanes addresses that are installed will be displayed. The backplane names will be sesX, where X is 0, 1, etc.
2) To check the current microcode level for the adapter enter the following command
lscfg -vl sesX
Where X is the number/s of the previous command. The Command will produce output similar to

Device
Manufacturer................IBM
Machine Type and Model......7031-D24/T24
ROS Level and ID............P013
Serial Number...............F5B02459
Device Specific.(Z0)........0D00020232004000
FRU Number..................12R7475
Device Specific.(FL)........P2
Device Specific.(FS)........5787-001 DQD048U

If the ROS Level and ID is less than P013 then you should update the microcode.
4.0 Downloading and Unpacking the Firmware Update Package from CORE
Note: The CORE image will now be the RPM Format File.
1) After downloading the files from CORE on to your personal system find the
files "ses7031.aix.P013.rpm" in
the CORE destination directory (c:\ibmdocs\DISKIMG).
2) Log in to the Target Server
3) Create a directory, if not already existent (mkdir /tmp/microcode; mkdir /tmp/microcode/RPM)
4) Transfer the file to the Target Server "/tmp/microcode/RPM
directory" using ftp or another method. Change to that directory, "cd /tmp/microcode/RPM".
5) Unpack the RPM file by using the following command:
for AIX: "rpm -ihv --ignoreos --force ses7031.aix.P013.rpm". The microcode file will be added to "/usr/lib/microcode/".
The
file size and checksum of the microcode image will be verified in
Section 5.0
4.1 Downloading the RPM Format File
to the Target Server
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.
a) Make a
directory on an AIX system to receive the RPM format file.
Enter: "mkdir /tmp/microcode"
Enter: "mkdir /tmp/microcode/RPM"
b) 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 is "ses7031.aix.P013.rpm"
c) Unpack the file by executing the command below.
for AIX: "rpm -ihv --ignoreos --force ses7031.aix.P013.rpm". The microcode file will be added to "/usr/lib/microcode/".
The
file size and checksum of the microcode image will be verified in
Section 5.0
4.2 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 System please go to:
http://www14.software.ibm.com/webapp/set2/firmware/gjsn?mode=10&page=cdrom.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 command below:
for AIX: "rpm -ihv --ignoreos --force ses7031.aix.P013.rpm". The microcode file will be added to "/usr/lib/microcode/".
The file size and checksum of the microcode image will be verified in Section 5.0
Note:
- If permission does not allow the copy to the above stated
directory
or file then the user will be prompted for a new location.

Verifying Microcode before download and notes
NOTE:
Microcode download must be performed separately for each Adapter bus under distinct Logical Partitions (LPAR's).
Please save current and older versions of the microcode update files in case you need to restore your system.
Microcode Download CAN be performed concurrently.
Installation Time: Approximately 30 min System Time.
Please verify the file size and checksum of the raw microcode files matches
the below.
Filesize: 14523
Checksum: 05608
For AIX, SLES9 base, RHEL3 & prior:
"ls -l /usr/lib/microcode/A170027A.P013" to verify
Filesize.
"sum /usr/lib/microcode/A170027A.P013" to
verify Checksum.
For SLES9 SP1, RHEL4 & above: "ls
-l /lib/firmware/A170027A.P013 to verify Filesize.
"sum /lib/firmware/A170027A.P013"
to verify Checksum.
For systems that have LPAR installed, the microcode file must be placed on all partitions that have the SES device in order to update the code. Follow this procedure for each partition:
For AIX
A) Log into the target partition.
B) Type: "cd /usr/lib/microcode"
C) FTP (for AIX) to the partition that has the media bay assigned. (ie.
ftp partition1.ibm.com)
D) Type: "cd /usr/lib/microcode"
E) If using FTP then Type: "bin"
F) Type: "get A170027A.P013"
G) Type: "quit"

Microcode Download Procedure for SCSI Enclosure Services for AIX
Procedure:
1) Type: "diag"
2) Select the "Task Selection" from diagnostics menu.
3) Select "Microcode Download" from "Task Selection"
menu.
4) Select the "sesX" (where X is the number of the ses
device) that needs to be updated from
the list of devices.
5) Select filesystem.
NOTE: If this level of ucode is already installed
in the backplane you will receive a message that will let you know. A
message may also be displayed if the /usr/lib/microcode directory does not
have the previous level microcode. This is true and is not required to
complete the download. Hit enter to continue.
6) The following message will
appear on the screen when download is completed: "The microcode
download has completed successfully, run diagnostics on the sesX
device". Please ignore the "run diagnostic" message and do NOT run
diagnostics on the SES device at this time.
7) Return to the Tasks Selection menu and repeat this
procedure for each SES that requires this microcode.
8) Exit diagnostics.
5.2 Microcode Download Procedure for SCSI Enclosure Services for Linux
Procedure:
1) There is currently no mechanism in place for updating this
microcode via Linux. If you have a Linux partition and wish to update the
microcode then you will have to use an AIX Diagnostics CD. The iso image
of the diag CD can be obtained from the URL below.
https://www14.software.ibm.com/webapp/set2/sas/f/diags/download/home.html
2) After securing the
Diagnostic's CD image, go to step 4.3 for information on how to burn the
microcode file(s) on to a CD in the .iso image format.
