1.2 Microcode Change History

Release date	Code level	Change Description
September 2010	C810	Fixed the following microcode bug: In rare situations when drive is left idle for extended period of time, it could damage the media
April 2009	C80F	Changed code to report PFA (SMART) error and force drive replacement after "Auto reallocation failure" errors
July 7, 2008	C80D	Corrected capacity values for 9.1 GB (introduced in C80A code).
April 14, 2008	C80A	After a drive reports error in AIX error log, and running AIX ELA (Error Log Analysis), drive reports zero for FFC (Failing Function Code). Also made code changes to support older disk drive FRU’s.
November 2007	C808	Changes made to drive microcode to monitor the number of CRC errors (drive-adapter communication errors), and if rate of CRC errors exceeds threshold, SCSI bus speed will change from 320MB/sec to 160MB/sec.
April, 2007	C806	Initial Release

===============================================================

2. AIX Operating System

2.1 Installation Time

Approximately 20 minutes if drive is part of rootvg(using Diagnostics CD); Approximately 5 minutes/drive if drive is not part of rootvg(using concurrent diagnostics).

2.2 Determine Drive Model, FRU&PN and Current Microcode Level

2.2.1 SCSI Drives attached to SCSI Controllers and PCI-X RAID Adapters

To see the drive type and current microcode level, Execute the following command:
lscfg -vl hdisk* |pg ; For drives NOT configured for RAID

lscfg –vl pdisk* |pg ; For drives configured for RAID

At AIX command line, type:
Diag
Select "Task Selection" from diagnostics menu.
Select "PCI RAID Physical Disk Identify"
Select SCSI RAID Adapter (press enter, then F7 to Commit)
This will display the Vital Product Data for Physical Disk drives attached to the RAID adapter.

===============================================================

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 CH15K5.bin
c) Unpack the file by executing the instructions below.
Enter the commands:
cd /tmp/fwupdate
chmod +x CH15K5.bin
./CH15K5.bin
[Don't overlook the periods (.) in the above command.]

The directory CH15K5 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/CH15K5/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/ ST37345.54493030.43383130| 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 CH15K5-C810-AIX.rpm

c) Unpack the file by executing the instructions below:
Enter the commands:
rpm -ihv --ignoreos --force CH15K5-C810-AIX.rpm

(note double dash --)

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.

2.4.1.1 AIX level 5.1 and above

2.4.1.2.1 Concurrent Download

1. Type diag at the prompt.
2. Select the "Task Selection" from diagnostics menu.
3. Select "Microcode Download" from "Task Selection" menu.
4. Select resource that microcode will be applied to(hdisk? For physical disk, pdisk for RAID configured disks) and press ENTER, then press "F7" to commit..
5- A small screen displays the message " *** NOTICE*** The microcode installation occurs while the attached drives are available for use..... "
    Press enter to continue
6. Select the source for microcode, use arrow key to go up/down, Enter to continue.
                      /etc/microcode
                      diskette

- Use /etc/microcode if "restore" command is used to copy files from diskette onto the disk
- Use diskette if using diskette as the source for download

NOTE: A prompt will ask you to insert the microcode diskette in diskette drive(if Diskette is selected above). Insert the diskette and press ENTER

7- Display shows a list of microcode files available for the selected drive, highlight option "M ST3xx...", the latest microcode for the drive and press ENTER. A message may warn you that current level of microcode is not available on the media, press ENTER to continue.

8. You will receive a msg. "Current Microcode is...." and "Download has completed successfully"
(this may take a few minutes)
9. Return to the Tasks Selection menu and repeat this procedure for each hard disk that requires this microcode.
10. Exit diagnostic(and reboot if needed).

2.4.1.2 AIX level 4.33:
This procedure is for drives that are not part of rootvg or paging space:
1. This step is optional. Microcode download can be performed either from Diskette or from Disk. To copy files from the diskette to disk, place the diskette containing microcode files into diskette drive A, at AIX Prompt type   restore
2- At AIX prompt, type   diag
3. Select the "Task Selection" from diagnostics menu.
4. Select "Microcode Download" from "Task Selection" menu.
5. Select resource that microcode will be applied to(hdisk?) and press ENTER.

    current is missing
NOTE: A prompt will ask you to insert the microcode diskette into the floppy drive(if Diskette is selected above). Insert the diskette which accompanies these instructions. If this level is already installed in the drive you've selected a message will let you know. A message also may come up to let you know that the Diskette(or Disk) does not have the previous level microcode file. This is true and is not required to complete the download.
PRESS "F7" to commit
8. You will receive a msg. "Current Microcode is....and...Download has completed successfully"
