1.0 Microcode Change History:
 

02220056	-CCIN 572A & 57B9 enhancement to add 2 extra retries upon configuration.  This modification was made to more reliably configure split backplane configurations without AIX reporting errors.  For these split backplane configurations, please install this code along w/ 9117-MMA SES microcode level 0021 or 8204-E8A/8203-E4A SES microcode level 0008 -Various Target Mode/Dual Controller enhancements.
02220050	GA Level for CCIN 57B9
0222004a	Fix for TEMP SISSAS_ERR11T logged against CCIN 57B7 during boot or other configuration time. That error decoded further as a REASON FOR FAILURE Timeout - op started. A microcode update to 57B8 addresses the issue.  It is best practice to apply the update to 57B7 when updating 57B8.
0222003c	Various Unit Check condition fixes (04448400 and 04448200 errors)
02220039	GA Level for CCIN 57B7

8204-E8A

8203-E4A

57B9

9117-MMA

2.3 AIX Requirements:
For support of 57B7: 

AIX 5.3 TL_06 w/ SP4 (Sevice Pack 4), AIX 5.3 TL_07, AIX 6.1 or above

For support of 57B9: 

AIX 5.3 TL_08, AIX 6.1 TL_01 or above

2.4 Linux Requirements:

For support of 57B7:

SUSE Linux Enterprise Server 10-SP1 for POWER or above
Red Hat Enterprise Linux AS for POWER Version 4 Update 6, RHEL 5 Update 1 or above

For support of 57B9:

SUSE Linux Enterprise Server 10-SP2 for POWER or above
Red Hat Enterprise Linux AS for POWER Version 4 Update 7, RHEL 5 Update 2 or above

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 SAS RAID Adapters installed in the system by typing:

    lsdev -C | grep sissas

Note: All of the SAS RAID initiators addresses that are installed will be displayed. The names will be sissasX, where X is 0, 1, etc.

2) To check the current microcode level for the adapter or controller enter the following command

   lscfg -vl sissasX

Where X is the number/s of the previous command. The Command will produce output similar to

 DEVICE   LOCATION                                 DESCRIPTION

 sissas1       U78A0.001.DNWFZYA-P1-Tx    PCI Express x1 Auxiliary Cache Adapter

ROM Level.(alterable).......02220026
Customer Card ID Number.....57B7

If the ROM Level is less than 02220056 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 SAS adapter by typing a "1" in front of it and pressing Enter.
4) The Command will produce output similar to
"Firmware Version . . . . . . . . . . . . : 02220056"

If the Firmware Version is less than 02220056 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 pci.10140339.22.02220056-1.aix5.1.noarch.rpm
    B) For Linux:  The filename is pci.10140339.22.02220056-1.Linux.noarch.rpm
3) Unpack the file by executing the instructions below:
    A) For AIX:  Type "rpm -ihv --ignoreos --force pci.10140339.22.02220056-1.aix5.1.noarch.rpm"
    B) For Linux:  Type "rpm -ihv --ignoreos --force pci.10140339.22.02220056-1.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 pci.10140339.22.02220056-1.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 Adapter bus 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 Download CAN be performed concurrently.

Installation Time:  Approximately 30 min System Time.

Please verify the file size and checksum of the raw microcode files matches the below.
Filesize:  1249496
Checksum:  05935
For AIX:  "ls -l /usr/lib/microcode/53495320.02220056" to verify Filesize. 
                "sum /usr/lib/microcode/53495320.02220056" to verify Checksum.
For Linux:  "ls -l /lib/firmware/pci.10140339.22.02220056" to verify Filesize.
                 "sum /lib/firmware/pci.10140339.22.02220056" to verify Checksum.

For systems that have LPAR installed, the microcode file must be placed on all partitions that have a SAS 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 53495320.02220056"
    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 pci.10140339.22.02220056"
    F)  Type: "quit"
