6.0 Microcode Readme Change History

=====================================================================================

1.0 Microcode Change History:
 

01B5	5886 POWER CYCLE REQUIRED when updating 0197 -> 01Bx 1) Resolves issue with 497 day timer reset.  Prior to this fix, ESM would reset during runtime when 497 day timer rolled over.  This could cause SAS Fabric Errors. 2) Required for support with FC 5913 (CCIN 57B5).  NOTE: It is best to apply this code level PRIOR to attaching to CCIN 57B5.  (Apply this code using an older 3Gb SAS adapter, if possible.) If only CCIN 57B5 is available then attach only 1 adapter to the drawer for the purpose of microcode update. Once the microcode update is applied to both ESMs, power cycle the 5886 drawer Cable the 5886 drawer in a correct supported manner.
0197	1) Extended SAS Expander communication timeout to 50 sec 2) Extended SSP timer to 42 sec In general, these changes are needed for systems where SSDs are used in the FC 5886 SAS Enclosure and the SAS adapter is in a slower MTM (7311-D20).
0193	1) Improved pre-emphasis settings to optimally drive 15m cables. 0197 or above must be installed for all 15m cable setups. 2) Fixed EPOW handling to properly recover expander after NOTIFY/Expected Power Loss has been sent. 3) Improved diagnostic call out in Received Diagnostics page so more errors are bubbled up to summary bit status field.
0184	GA Level

 

2.0 General Information

2.1 Installation Time:
Approximately 30 minutes
 
2.2 Machine's Affected:
FC 5886

2.3 AIX Requirements:
For support:

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

2.4 Linux Requirements:

For support:

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

Manufacturer................IBM
Machine Type and Model......5886
ROM Level.(alterable).......0197
Serial Number...............00901113
FRU Number.................. 42R7599
Device Specific.(Z0)........0D00040227004002
Hardware Location Code......U5886.001.0901113-C1

ses11 U5886.001.0901113-C2 SAS Enclosure Services Device

Manufacturer................IBM
Machine Type and Model......5886
ROM Level.(alterable).......0197
Serial Number...............00901113
FRU Number.................. 42R7599
Device Specific.(Z0)........0D00040227004002
Hardware Location Code......U5886.001.0901113-C2

If the ROM Level and ID is less than 01B5 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 . . . . . . . . . . . . : 0197"

If the Firmware Version is less than 01B5 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.5886-01B5-1.aix6.1.noarch.rpm"
    B) "ses.5886-01B5-1.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.5886-01B5-1.aix6.1.noarch.rpm"
5b) For Linux:  Unpack the RPM file by using the following command:  "rpm -ihv --ignoreos --force ses.5886-01B5-1.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:

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.5886-01B5-1.aix6.1.noarch.rpm
    B) For Linux:  The filename is ses.5886-01B5-1.Linux.noarch.rpm
3) Unpack the file by executing the instructions below:
    A) For AIX:  Type "rpm -ihv --ignoreos --force ses.5886-01B5-1.aix6.1.noarch.rpm"
    B) For Linux:  Type "rpm -ihv --ignoreos --force ses.5886-01B5-1.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.5886-01B5-1.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.

Installation Time:  Approximately 30 min System Time.

Please verify the file size and checksum of the raw microcode files matches the below.
Filesize:  693424
Checksum:  08198
For AIX:  "ls -l /usr/lib/microcode/A170027C.01B5" to verify Filesize. 
                "sum /usr/lib/microcode/A170027C.01B5" to verify Checksum.
For Linux:  "ls -l /lib/firmware/IBM-A170027C.01B5" to verify Filesize.
                 "sum /lib/firmware/IBM-A170027C.01B5" 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 A170027C.01B5"
    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-A170027C.01B5"
    F)  Type: "quit"
