1.0 Microcode Change History:
 

02200059	-Fix for 572B in Dual Controller mode.  The adapter will no longer log a 9076 error on a boot, if the system contains 572B's that have no FC 5886 SAS drawers attached.
02200056	-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.
02200050	-GA Level for 572B -This microcode level fixes a potential undetected loss of data that was discovered in test between CCIN 572A and DAT72 SAS tape drive (FC 1400 or 5907). There have been no reported cases of this occurring in the field and the chance of occurrence is extremely small - near 0.
0220004a	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.
0220003c	Various Unit Check condition fixes (04448400 and 04448200 errors)
02200039	GA Level for CCIN 57B8.
02200035	GA Level for CCIN 572A, 572C on 7998-61X
01200041	-Data error fix for Low probability condition.  If data loss is discovered on two devices at very close intervals, it was possible that the indication of this condition could have been lost on device 2 during device 1's recovery.
0120003b	-Numerous functional enhancements to prevent adapter error and Unit Check Conditions. Unit Checks require an adapter reset to recover. -Fix for error logged during AIX concurrent maintenance when DVD drive is removed and not replaced.
01200037	GA Level for CCIN 572C

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

For 572A

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 . . . . . . . . . . . . : 02200035"

If the Firmware Version is less than 02200059 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.101402BD.20-02200059-1.aix5.1.noarch.rpm
    B) For Linux:  The filename is pci.101402BD.20-02200059-1.Linux.noarch.rpm
3) Unpack the file by executing the instructions below:
    A) For AIX:  Type "rpm -ihv --ignoreos --force pci.101402BD.20-02200059-1.aix5.1.noarch.rpm"
    B) For Linux:  Type "rpm -ihv --ignoreos --force pci.101402BD.20-02200059-1.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.101402BD.20-02200059-1.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:  1249248
Checksum:  33825
For AIX:  "ls -l /usr/lib/microcode/53495320.02200059" to verify Filesize. 
                "sum /usr/lib/microcode/53495320.02200059" to verify Checksum.
For Linux:  "ls -l /lib/firmware/pci.101402BD.20.02200059" to verify Filesize.
                 "sum /lib/firmware/pci.101402BD.20.02200059" 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 53495320.02200059"
    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.101402BD.20.02200059"
    F)  Type: "quit"

5.1 Microcode Download Procedure-572A, 572C, 57B8 SAS Adapters 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 Adapters/Controllers that need to be updated from the list of devices by pressing "Enter".  The devices will be displayed as sissas#, 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 sissas# 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 02200059 by typing "lscfg -vl sissas#" for each SAS device updated. <Where # is the number sissas device>
