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
DEVICE LOCATION DESCRIPTION
ses2 U78C9.001.WZS0059-P2-Y2 SAS Enclosure Services Device
SAS Expander:
FRU Number..................00E1976
Serial
Number...............YL30UF39400R
Customer Card ID Number.....2B0F
Product Specific.(ZM).......1
Load ID.....................A1700DF2
ROM Level.(alterable).......1508
Hardware Location
Code......U78C9.001.WZS0059-P2-Y2
If the ROM Level is less than 1508 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 . . . . . . . . . . . . : 01508"
If the Firmware Version is less than 1508 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.2B0F-1508-1.aix5.1.noarch.rpm "
B) "ses.2B0F-1508-1.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.2B0F-1508-1.aix5.1.noarch.rpm
"
5b) For Linux: Unpack the RPM file by using the following
command: "rpm -ihv --ignoreos --force ses.2B0F-1508-1.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 or Linux system:
Note: The instructions that follow are specific AIX/Linux commands. AIX/Linux commands are CASE (lower and upper) SENSITIVE, and must be entered exactly as shown, including filenames.
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.2B0F-1508-1.aix5.1.noarch.rpm
B) For Linux: The filename is ses.2B0F-1508-1.Linux.noarch.rpm
3) Unpack the file by executing the instructions below:
A) For AIX: Type "rpm -ihv --ignoreos --force ses.2B0F-1508-1.aix5.1.noarch.rpm
"
B) For Linux: Type "rpm -ihv --ignoreos --force ses.2B0F-1508-1.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:
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.2B0F-1508-1.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.
NOTE: Microcode update cannot
be performed to both SAS expanders (SES) at the same time.
Installation Time: Approximately 30 min System Time.
Please
verify the file size and checksum of the raw microcode files matches the below.
Filesize: 197408
Checksum: 24497
For AIX: "ls -l /usr/lib/microcode/A1700DF2.1508 " to verify Filesize.
"sum /usr/lib/microcode/A1700DF2.1508 " to
verify Checksum.
For Linux: "ls -l /lib/firmware/A1700DF2.1508
" to verify Filesize.
"sum /lib/firmware/A1700DF2.1508 " 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 A1700DF2.1508 "
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 A1700DF2.1508 "
F) Type: "quit"

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 1508 by typing "lscfg
-vl ses#"
for each SES device updated. <Where # is the number ses device>
