1.0 Microcode Change History:
 

0109

-Corrected EPOW function to send Notify Primitive Previously, the SAS Expanders on this DASD backplane would not send the Notify (of unexpected power off) primitive on an EPOW (unexpected power off event).  Notify gives the disk drive a slight advance warning that power is about to drop.  When Notify is received, the drive stops accepting new write commands and finishes all writes in process prior to power off. Without the notify being received, there is a slight chance that a write command could be in process.  If that occurred then there would be a write splice on the disk drive. On the next drive power on, this would be detected as a bad sector.

0108

-GA Level

 

2.0 General information

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:
8231-E1C/E1D/E2B/E2C/E2D

2.3 AIX Requirements:

AIX 5.3TL10 SP5

AIX 5.3TL11 SP5

AIX 5.3TL12 SP2

AIX, 6.1TL06

AIX 7.1

or above 

2.4 Linux Requirements:

SUSE Linux Enterprise Server 10-SP3, 11-SP1 for POWER or above
Red Hat Enterprise Linux for POWER Version 5 Update 5 or above

2.5 IBM i Requirements:

IBM I 7.1 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

ses0            U78AB.001.WIH000W-P2-Y2     SAS Enclosure Services Device

ROM Level.(alterable).......0108
Hardware Location Code......U78AB.001.WIH000W-P2-Y2

If the ROS Level and ID is less than 0109 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 . . . . . . . . . . . . : 0108"

If the Firmware Version is less than 0109 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.5268.6pack-0109-1.aix5.1.noarch.rpm
    B) For Linux:  The filename is ses.5268.6pack-0109-1.Linux.noarch.rpm
3) Unpack the file by executing the instructions below:
    A) For AIX:  Type "rpm -ihv --ignoreos --force ses.5268.6pack-0109-1.aix5.1.noarch.rpm"
    B) For Linux:  Type "rpm -ihv --ignoreos --force ses.5268.6pack-0109-1.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 Microcode Update via CD

Below are references and the general flow on how to update microcode update via CD
1) Boot the system via a Standalone Diagnostic's CD
b) To create a bootable Diagnostic's CD go to the following URL.
Burn cdlatest.iso on to a CD-R (or CD-RW). Currently, DVD media cannot be utilized.
http://www14.software.ibm.com/webapp/set2/sas/f/diags/home.html
c) After booting to Standalone Diagnostics, the Diagnostic's CD can be removed.

2) The Diagnostic's CD should be replaced by a CD containing the unpacked microcode image(s).
The CD containing the microcode images should be prepared prior. This can be done by taking the rpm file(s) from the microcode download site and unpacking them on a usable server. The unpacked files can then be burned on to the CD media.
b) Another method is to use a Microcode Update CD
See the below website for more details

The Microcode Update CD and Discovery Tool can also be ordered through the following link

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:  402304
Checksum:  40096
For AIX:  "ls -l /usr/lib/microcode/A1700DED.0109" to verify Filesize. 
                "sum /usr/lib/microcode/A1700DED.0109" to verify Checksum.
For Linux:  "ls -l /lib/firmware/IBM-A1700DED.0109" to verify Filesize.
                 "sum /lib/firmware/IBM-A1700DED.0109" 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 A1700DED.0109"
    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-A1700DED.0109"
    F)  Type: "quit"

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 0109 by typing "lscfg -vl ses#" for each SES device updated. <Where # is the number ses device>
