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

Example shown for FC EPVN, CCIN 2CCA

DEVICE LOCATION DESCRIPTION

ses2 U78C7.001.1AQH4D9-P2-C1-Y4 SAS Enclosure Services Device

SAS Expander:

FRU Number..................00E3968

Serial Number...............YA30BG4CK001

Customer Card ID Number.....2CCA

Product Specific.(ZM).......2

Load ID.....................A1700DF4

ROM Level.(alterable).......1D0B

Hardware Location Code......U78C7.001.1AQH4D9-P2-C1-Y4

If the ROM Level is less than 1D0B 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 . . . . . . . . . . . . : 01D0B"

If the Firmware Version is less than 1D0B 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-1D0B-1.aix6.1.noarch.rpm"
B) "ses-1D0B-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-1D0B-1.aix6.1.noarch.rpm "
5b) For Linux: Unpack the RPM file by using the following command: "rpm -ihv --ignoreos --force ses-1D0B-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-1D0B-1.aix6.1.noarch.rpm
    B) For Linux: The filename is ses-1D0B-1.Linux.noarch.rpm
3) Unpack the file by executing the instructions below:
    A) For AIX: Type "rpm -ihv --ignoreos --force ses-1D0B-1.aix6.1.noarch.rpm"
    B) For Linux: Type "rpm -ihv --ignoreos --force ses-1D0B-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-1D0B-1.aix6.1.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: 257992
Checksum: 05149
For AIX: "ls -l /usr/lib/microcode/A1700DF4.1D0B " to verify Filesize.
"sum /usr/lib/microcode/A1700DF4.1D0B " to verify Checksum.
For Linux: "ls -l /lib/firmware/A1700DF4.1D0B " to verify Filesize.
"sum /lib/firmware/A1700DF4.1D0B " 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 A1700DF4.1D0B "
    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 A1700DF4.1D0B "
    F) Type: "quit"

5.1 Microcode Download Procedure-SAS Enclosure Services 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 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 1D0B by typing "lscfg -vl ses#" for each SES device updated. <Where # is the number ses device>
