The Microcode files provided in this package are only for use when installing disk drive microcode to a disk drive installed in a pSeries Server or 2104 drawer using the AIX or Linux Operating System.

NOTICE and UPDATE:

IBM recently identified an isolated scenario, which can cause incorrect data to be stored on disk drives during a hung command. These disk drives that were shipped from November 2007 to April 2008 may still be running FW Levels S2C0 and S2C5. A fix was released on April 2008 to handle the underlying hang scenario and it has been determined that the same fix properly resolves this newly identified issue. All firmware at the S400 level (or higher) would address this issue.

a) Make a directory on an AIX system to receive the AIX format file.
Enter: mkdir /tmp/fwupdate
b) Transfer the AIX format file to /tmp/fwupdate directory (using "Save as ...").
You'll see the filename is 15k300.bin
c) Unpack the file by executing the instructions below.
Enter the commands:
cd /tmp/fwupdate
chmod +x 15k300.bin
./15k300.bin
[Don't overlook the periods (.) in the above command.]

The directory 15k300 with microcode files listed in section 1.1 will be added to /tmp/fwupdate.

d-Enter the following command to copy the microcode files to " /etc/microcode " directory :
cp /tmp/fwupdate/15k300/HUS1530* /etc/microcode

e- If transferring files to a different system using floppy diskettes, use the following procedure to copy files to diskette
Note: Don't overlook the complete path of microcode files, AIX Diag microcode download will not work if files are not copied with complete path onto the diskette. Enter the following command to copy microcode file(s) onto a floppy diskette
ls /etc/microcode/ microcodefilename | backup -ivf /dev/rfd0
where microcodefilename is microcode file that is needed, for example:
ls /etc/microcode/ HUS1530.56425030.53343234 | backup -ivf /dev/rfd0

2.3.2 AIX RPM package

Note: The instructions that follow are specific AIX commands. AIX commands are CASE (lower and upper) SENSITIVE, and must be entered exactly as shown, including filenames.

a) Make a directory on an AIX system to receive the RPM format file.
Enter: mkdir /tmp/microcode

b) Transfer the RPM format file to the /tmp/microcode directory (using "Save as ...").
You'll see the filename is 15k300-S424-AIX.rpm

c) Unpack the file by executing the instructions below:
Enter the commands:
rpm -ihv –ignoreos --force 15k300- S424-AIX.rpm

The file size and checksum will be verified.

The microcode files will be added to /etc/microcode/

2.3.3 CD-ROM

Create microcode CD using instruction and tool available on IBM web site (CD-ROM Image):

http://techsupport.services.ibm.com/server/mdownload2/cdimage.html

Once CD is created, use concurrent or stand alone microcode download procedure in section 2.4,

or copy files onto your local disk.

Notes:

1. RPM packaged microcode files will be copied to "/tmp/microcode/RPM"
2. Microcode files will be copied to /usr/lib/microcode

3. "/etc/microcode" is a symbolic link to "/usr/lib/microcode".
4. If permission does not allow the copy to the above stated directory
or file then the user will be prompted for a new location.

2.4 Microcode Download Procedure

2.4.1 SCSI Drives Attached to SCSI Adapter

Warning: Do not power off the system or the drive during microcode download as this may permanently damage the disk drive

NOTE: Please save current and older versions of the microcode update files in case you need to restore your system.

Caution: The microcode download process is nondestructive to the hard disks; however, as a precaution, ensure that a backup operation has been performed on the affected systems PRIOR to the microcode installation.

Can microcode be installed Concurrently?
AIX level 5.1 and above supports concurrent microcode download on all drives, including drives that are part of rootvg.
AIX level 4.33 and below does not support concurrent microcode download if drive is part of rootvg, microcode download can ONLY be performed in service mode(stand alone) using diagnostics CD. If disk is not part of rootvg, microcode download can be performed cuncurrently as long as drive is not in use.

Is system reboot needed to activate the microcode: Yes if stand alone diagnostics is used, NO if concurrent diagnostics is used.

Installation Time: Approximately 20 minutes/drive if stand alone diagnostics is used(using Diagnostics CD); Approximately 5 minutes/drive if consurrent diagnostics is used.
