2.1
Installation Time:
Approximately 90 minutes
2.2
Machine's Affected:
9125-F2C DE
2.3
AIX Requirements:
For support:
7.1 SP3
For support:
HPC SP7.0 or later
For support:
This feature is not supported
in IBM i
3.0 Determine the Current Microcode Level for AIX:
Note: If the system is running a GPFS file system under AIX,the GPFS file system must shutdown GPFS prior to updating the expander firmware. Use the mmshutdown and mmstartup command for this.
Before you install the microcode, it is important to determine the microcode level of the Adapter installed in the target system. Use
the following instructions to read the ROM level stored in the Adapter's VPD.
1) List the SES installed in the system by typing:
lsdev -C | grep ses
Note: All of the SAS RAID initiators addresses that are installed will be displayed. The names will be sesX, where X is 0, 1, etc.
2) To check the current microcode level for the adapter or controller 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 LOCATION DESCRIPTION
ses3 U78AD.001.00DE40-P1-C61 SAS
Enclosure Services Device
SAS Expander
FRU Number..................74Y2390
Serial Number...............YH10UE11K009
Customer Card ID Number.....2A4A
ROM Level.(alterable).......0155
Hardware Location Code......U78AD.001.000DE40-P1-C61
If the ROM Level and ID is
less than 0161 then you should update the microcode.
3.1 Determine the Current Microcode Level for Linux:
1) get a list of SAS expander device names
If the ROM Level and ID is
less than 0161 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 following files in the CORE destination directory (c:\ibmdocs\DISKIMG):
"A)ses.0273-0161-1.aix7.1.noarch.rpm"
"B)ses.0273-0161-1.Linux.noarch.rpm"
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".
5a) For AIX:
Unpack the RPM file by using the following command: "rpm -ihv --ignoreos --force
ses.0273-0161-1.aix7.1.noarch.rpm"
5b) For Linux:
Unpack the RPM file by using the following command: "rpm -ihv --ignoreos --force
ses.0273-0161-1.Linux.noarch.rpm"
6a) For AIX:
The microcode files will be added to /usr/lib/microcode/.
6b) For Linux:
The microcode files will be added to /lib/firmware/.
4.1 Downloading the RPM Format File
to the Target Server
Use this
method to download to an AIX/Linux system:
1) Make a directory on an AIX/Linux system to receive the RPM format file.
Enter: "mkdir /tmp/microcode"
Enter: "mkdir /tmp/microcode/RPM"
2) 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
filenames for the RPM files.
A) For AIX:
The filename is ses.0273-0161-1.aix7.1.noarch.rpm
B) For Linux:
The filename is ses.0273-0161-1.Linux.noarch.rpm
3) Unpack the file by executing the instructions
below:
A) For AIX:
Type "rpm -ihv --ignoreos --force ses.0273-0161-1.aix7.1.noarch.rpm"
B) For Linux:
Type "rpm -ihv --ignoreos --force ses.0273-0161-1.Linux.noarch.rpm"
4a) For AIX:
The microcode files will be added to /usr/lib/microcode/.
4b) For Linux:
The microcode files will be added to /usr/lib/firmware/.
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://techsupport.services.ibm.com/server/mdownload/CDROMhelp.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 instructions below:
Enter the commands:
rpm -ihv --ignoreos --force
ses.0273-0161-1.aix7.1.noarch.rpm
4) Microcode files will be copied to "/etc/microcode". The file
size and checksum of the microcode image will be verified in Section
5.0
Notes:
- "/etc/microcode" is a symbolic link to "/usr/lib/microcode".
- If permission does not allow the copy to the above stated
directory
or file then the user will be prompted for a new location.
5.0 Verifying microcode before download and notes
NOTE: Microcode download must be performed
separately for each "ses" 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.
Installation Time: Approximately 90 min System Time.
Please verify the file size and checksum of the raw microcode files
matches the below.
Filesize: 621024
Checksum: 19100
For AIX: "ls -l /usr/lib/microcode/A1700DEE.0161" to
verify Filesize.
"sum /usr/lib/microcode/A1700DEE.0161"
to verify Checksum.
For Linux: "ls -l /lib/firmware/A1700DEE.0161" to
verify Filesize.
"sum /lib/firmware/A1700DEE.0161"
to verify Checksum.
For systems that have LPAR installed, the microcode file must be placed on all partitions that have a 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
D) Type: "cd /usr/lib/microcode"
E) If using FTP
then Type: "bin"
F) Type: "get A1700DEE.0161"
G) Type: "quit"
For Linux:
A) Log into the
target partition.
B) Type: "cd /lib/firmware"
C) FTP
D) Type: "cd /lib/firmware"
E) If using FTP
then Type: "bin"
F) Type: "get A1700DEE.0161"
G) Type: "quit"
5.1 Microcode Download Procedure-SAS Enclosure Services for 9125-F2C 0161 for AIX
Procedure:
1) It is advised, but not necessary to stop all applications.
2) Enter diag
3) Select the "Task Selection" from diagnostics menu.
4) Select "Download Microcode" or "Microcode Tasks -> Download
Microcode" from "Task Selection"
menu.
5) Select all of the SAS Enclosure Services for SES devices
that need to be updated from the list of devices by pressing "Enter".
The devices will be displayed as ses#, where # is the number of
the device. Press "F7".
6) A dialogue box will be displayed on screen. Press "Enter" to
continue.
7) Select "/usr/lib/microcode".
8) A dialogue box will may be displayed on screen. It will state
that
the current microcode level on the adapter is not in the
/usr/lib/microcode
directory. This is acceptable as you will be flashing new
microcode
onto the adapter. Also, incorrect code will automatically be
rejected. Press "Enter" to continue.
9) An "M" will be displayed next to the latest level of microcode in
the /usr/lib/microcode directory. Select that level and press
"Enter".
10) The following message
will
appear on the screen when download is completed: "Microcode download
complete successfully. The current microcode level for the device
ses# is ..... Please run diagnostics on the adapter to
ensure
that it is functioning properly." DO NOT run
diagnostics on the device at this time.
11) Exit diagnostics.
12) Verify the code level is 0161 by typing
"lscfg -vl ses#" for each SES device updated. <Where
# is
the number ses device>

Microcode Download Procedure-SAS Enclosure Services for 9125-F2C 0161 for
Linux
For Non-Concurrent Update:
1) Shutdown GPFS.
2) Get device names for all SAS expanders.
3) Use sg_write_buffer to update FW on SAS expander.
> sg_write_buffer -l {FW file name} -m 0x7 {device name}
4) Wait 30 seconds
5) Verify all expanders are seen in Linux.
> lsscsi -g | grep encl | wc
6) If all expanders are seen, continue repeat step 3 with the next expander,
if not all expanders are seen, stop and correct the issue.
For Concurrent Update:
