2.3 Transferring and Unpacking the Microcode Update Package

2.3.1 Internet AIX self extracting file (.bin)

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 SAS15K5.bin
c) Unpack the file by executing the instructions below.
Enter the commands:
cd /tmp/fwupdate
chmod +x SAS15K5.bin
./SAS15K5.bin
[Don't overlook the periods (.) in the above command.]

The directory SAS15K5 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/ SAS15K5/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/ ST37345.A1700D11.45303130 | backup -ivf /dev/rfd0

2.3.2 Internet 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.
You'll see the filename is SAS15K5-E010-AIX.rpm

c) Unpack the file by executing the instructions below:
Enter the commands:
rpm -ihv --ignoreos --force SAS15K5–E010-AIX.rpm

The file size and checksum will be verified.

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

2.3.3 CD-ROM

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.
========================================================

2.4 Microcode Download Procedure

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? YES
Is system reboot needed to activate the microcode: Yes if stand alone diagnostics CD 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 concurrent diagnostics is used.
