1.2 Microcode Change History

Release date

Code level

Change Description

6/9/2004

S28H

This code change fixes the following problem which affects Ultra 320 mode of operation only: If for any reason drive becomes “Format Corrupt” (i.e. format operation is interrupted), drive can not be formatted again in Ultra 320 mode (it can be formatted in U160 or other modes).

2/2/2004

S28F

Non functional fixes for U320 adapters only. Code fix to prevent entry into AIX error log during microcode download to a drive that is attached to U320 RAID Adapter and configured as a RAID drive (522 Bytes/ sector formatted drive).  Also, code change to enhance drive’s write operation performance when attached to U320 adapters.

 10/2002

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 S28H.bin
c) Unpack the file by executing the instructions below.
  Enter the commands:
  cd /tmp/fwupdate
  chmod +x S28H.bin
  ./S28H.bin
[Don't overlook the periods (.) in the above command.]

The directory S28H 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/S28H/IC35L*  /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/ IC35L01.44533030.53323848  | 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 (using "Save as ...").
    You'll see the filename is 2104_ic35l-S28H.rpm

c) Unpack the file by executing the instructions below:
    Enter the commands:
        rpm -ihvignoreos  2104_ic35l-S28H.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

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.
