1.0 Microcode Change History:
 

0016	-Support for 9117-MMA split backplane (PCI-X SAS Adapter attachment to SAS enclosure in 3-3 or 6-0 configuration) -Minor enhancements to the SAS Expander including timing and PHY voltage level changes.
0014	GA Level

 

2.0 General information

NOTE:  If using the split backplane feature then microcode will need to be updated on all four "ses" appearing in the configuration.

NOTE:  Microcode update cannot be performed to both SAS expanders (SES) at the same time.

2.1 Installation Time:
Approximately 30 minutes
 
2.2 Machine's Affected:
9117-MMA

2.3 AIX Requirements:
For support: 

AIX 5.2 TL_10, AIX 5.3 TL_06, AIX 6.1 or above

2.4 Linux Requirements:

For support:

SUSE Linux Enterprise Server 10 for POWER or later
Red Hat Enterprise Linux AS for POWER Version 4 Update 4 or later

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

 ses1           U789D.001.DQDTTPM-P3          SAS Enclosure Services Device

Manufacturer................IBM
Machine Type and Model......PSBPD6L4 3GSAS
ROS Level and ID............0016
Serial Number...............
Device Specific.(YL)........U789D.001.DQDTTPM-P3

If the ROS Level and ID is less than 0016 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 . . . . . . . . . . . . : 0016"

If the Firmware Version is less than 0016 then you should update the microcode.

4.0 Downloading and Unpacking the Firmware Update Package from CORE

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.9117MMA-0016-1.aix5.1.noarch.rpm
    B) For Linux:  The filename is ses.9117MMA-0016-1.Linux.noarch.rpm
3) Unpack the file by executing the instructions below:
    A) For AIX:  Type "rpm -ihv --ignoreos --force ses.9117MMA-0016-1.aix5.1.noarch.rpm"
    B) For Linux:  Type "rpm -ihv --ignoreos --force ses.9117MMA-0016-1.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.9117MMA-0016-1.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: If using the split backplane feature then microcode will need to be updated on all four "ses" appearing in the configuration.
 

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:  586604
Checksum:  28359
For AIX:  "ls -l /usr/lib/microcode/A170027B.0016" to verify Filesize. 
                "sum /usr/lib/microcode/A170027B.0016" to verify Checksum.
For Linux:  "ls -l /lib/firmware/IBM-30303037.0016" to verify Filesize.
                 "sum /lib/firmware/IBM-30303037.0016" 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 A170027B.0016"
    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-30303037.0016"
    F)  Type: "quit"
