2.3 Transferring and Unpacking the Microcode Update Package

2.3.1 Internet AIX self extracting file (.bin)

a) Make a directory on 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 10K200_XP-C49C.bin
c) Unpack the file by executing the instructions below.
Enter the commands:
cd /tmp/fwupdate
chmod +x 10K200_XP-C49C.bin
../10K200_XP-C49C.bin
[Don't overlook the periods (.) in above command.]

The directory C49C.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/C49C/* /etc/microcode

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 C10K147_XP-C49C-AIX.rpm

c) Unpack the file by executing the instructions below:
Enter the commands:
rpm -ihv --ignoreos --force C10K147_XP– C49C-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.

4.0 Drive Fails Code Update in Power Blade JS21

NOTE: The following problem only applies to AIX microcode download in JS21 blade; it does not affect other blades and/or operating systems

Problem Description:

With disk drive version at or below C49B, microcode update in a Power Blade JS21 using AIX diagnostic utility or Standalone AIX diagnostic CD will fail with the following message:

A software error occurred. Contact the service

support structure for further assistance.

Workaround:

Before updating the drive microcode, use the “chdev” command to change the ‘max_transfer’ size to allow the download utility to transfer larger amount of data.

chdev -l hdisk0 -a max_transfer=0x100000 For data drive

chdev -l hdisk0 -a max_transfer=0x100000 –P For OS drive

Note: Reboot is required after the command for OS drive.

After updating the drive microcode, make sure to set ‘max_transfer’ rate back to 0x40000.

chdev -l hdisk0 -a max_transfer=0x40000 For data drive

chdev -l hdisk0 -a max_transfer=0x40000 –P For OS drive

Note: Reboot is required after the command for OS drive.

Note: a. There is no workaround to update the microcode from Standalone Diagnostic CD. This workaround Requires AIX operating system command line.
