match the one listed in section 1.1 AND the "ROS Level and ID...."
field of that data is below "4335304B",
this microcode applies. If this level is already installed then the "ROS
Level and ID...." shows: "4335304B "
Note: Drive microcode level in “ROS Level and ID …” field is displayed
in Hex value of ASCII characters in VPD data. Each alpha-numeric ASCII
character converts to a 2-digit hex number. For example in VPD displayed above,
43 Hex= ASCII character "C"; 35 Hex= ASCII character "5"; 30 Hex=ASCII character "0"; 4B Hex=ASCII character "K", microcode level is "C50K".
For SP systems with multiple nodes, you can use the following command to query all of the nodes at one time. Use of this command will also limit the amount of data returned, making it easier to audit. It returns only the pertinent information: node name, hdisk number, ROS Level and ID and part number.

b) Transfer the AIX format file to /tmp/fwupdate
directory (using "Save as ...").
You'll see the filename is 146lp.bin
c) Unpack the file by executing the instructions below.
Enter the commands:
cd /tmp/fwupdate
chmod +x 146lp.bin
./146lp.bin
[Don't overlook the periods (.) in the above command.]
The directory 146lp 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/146lp/ST3* /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/ ST31830.53313030.4335304B | backup -ivf /dev/rfd0
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 146lp-C50K-AIX.rpm
c) Unpack the file by executing the
instructions below:
Enter the commands:
rpm -ihv
–ignoreos 146lp-C50K -AIX.rpm
The file size and checksum will be verified.
The microcode files will be added
to /etc/microcode/
Copy microcode updates from the CD-ROM to standard locations on your local disk:
1. RPM packaged microcode files
will be copied to "/tmp/microcode/RPM"
2. Microcode files will be copied to /usr/lib/microcode
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.
========================================================
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.
