3.0 Determine the Current Microcode Level for AIX:
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

If the ROM Level and ID is
less than 0193 then you should update the microcode.
3.1
Determine the Current Microcode Level for Linux:
1) Type "iprconfig"
2) Select "Display hardware status"
3) Select SES by typing a "1" in front of it and pressing
Enter.
4) The Command will
produce output similar to
"Firmware Version . . . . . . . .
. . . . : 0184"
If the Firmware Version is less
than 0193 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.
4.1 Downloading the RPM Format File
to the Target Server
Use this
method to download to an AIX or 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.5886-0193-1.aix5.1.noarch.rpm
B) For
Linux: The filename is
ses.5886-0193-1.Linux.noarch.rpm
3) Unpack the file by executing the instructions
below:
A) For AIX:
Type "rpm -ihv --ignoreos --force ses.5886-0193-1.aix5.1.noarch.rpm"
B) For Linux:
Type "rpm -ihv --ignoreos --force ses.5886-0193-1.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 /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: 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.5886-0193-1.aix5.1.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 30 min System Time.
Please verify the file size and checksum of the raw microcode files
matches the below.
Filesize: 685260
Checksum: 44433
For AIX: "ls -l /usr/lib/microcode/A170027C.0193" to
verify Filesize.
"sum /usr/lib/microcode/A170027C.0193"
to verify Checksum.
For Linux: "ls
-l /lib/firmware/IBM-A170027C.0193"
to
verify Filesize.
"sum /lib/firmware/IBM-A170027C.0193" 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 (for AIX)
or SFTP (for Linux) to the partition
that has the media bay assigned. (ie. ftp/sftp partition1.ibm.com)
D) Type: "cd /usr/lib/microcode"
E) If using FTP
then Type: "bin"
F) Type: "get A170027C.0193"
G) Type: "quit"
For Linux:
A) Log into the
target partition.
B) Type: "cd
/lib/firmware"
C) SFTP to the
partition
that has the media bay assigned. (ie. "sftp partition1.ibm.com")
D) Type: "cd /lib/firmware"
E) Type: "get IBM-A170027C.0193"
F) Type: "quit"

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 0193 by typing
"lscfg -vl ses#" for each SES device updated. <Where
# is
the number ses device>
