2.0.1 Installation
Time:
Approximately 30 minutes
3.0 Determine the Current Microcode Level:
Before you install the microcode, it is important to determine the microcode level of the backplane installed in the target system. Use
the following instructions to read the ROS Level and ID stored in the backplane's VPD.
1) List the SCSI initiators (adapters and controllers) installed in the system by typing:
lsdev -C | grep scsi
Note: All of the SCSI initiators addresses that are installed will bedisplayed. The SCSI initiators names will be scsiX, where X is 0, 1, etc.
2) To check the current microcode level for the adapter enter the following command
lscfg -vl scsiX
Where X is the number/s of the previous command. The Command will produce output similar to
DEVICE LOCATION DESCRIPTION
scsi0 1S-08-00 PCI-X Dual Channel Ultra320 SCSI
Adapter bus
ROM Level.(alterable).......020A0018
If the ROM Level is less than XXXX0018 then you should update the microcode.4.0.0 Downloading and Unpacking the Firmware Update Package from the WEB
b) Transfer the AIX format file to the /etc/microcode directory (using
"Save as ...").
You'll see the filename is scsi0018.bin
c) Unpack the file by executing the instructions below. You will be asked
for the password from the license agreement.
Enter the commands:
cd /etc/microcode
chmod +x scsi0018.bin
./scsi0018.bin
[Don't overlook the periods (.) in the above command.]
The directory scsi0018 with these files will be added to /etc/microcode.
1) 44415255.020a0018 (Microcode Image)
Enter the following command to copy the microcode files to " /etc/microcode
" directory :
cp /etc/microcode/scsi0018/44415255.020a0018 /etc/microcode
Enter the following commands to copy these file onto a diskette:
ls /etc/microcode/44415255.020a0018 | backup -i -v -f/dev/rfd0
This will produce AIX backup diskettes. Label the diskettes:
"PCI-X Dual Channel Ultra320 SCSI Adapter bus"
4.0.1 Downloading and Unpacking the Firmware Update Package from CORE
With the machine powered ON and AIX operational but no activity,
perform the following steps to install the FLASH code into the
SCSI Adapter bus.
1. Insert diskette with the file downloaded from CORE into the floppy diskette drive of the Media Bay.
NOTE: If the system is running LPAR, you must determine what partition has the media bay assigned.
How to determine what partition has the diskette
drive assigned when running LPAR:
A. Log onto the Hardware
Management Console (HMC).
B. On the opening screen,
in the Navigation Area, select Partition Management.
C. In the Partition Management
window, right-click on the top device listed in the window. Select
Properties.
D. Select the IOSLOT tab.
E. In the IOSLOT field,
find the SCSI initiator named PCI-X Dual Channel Ultra320 SCSI Adapter bus.
F. Click on the + sign next
to the I/O Group associated with the PCI-X Dual Channel
Ultra320 SCSI Adapter bus. This
will display the partition associated with the diskette drive.
2. Log into the target system (or LPAR that has the media bay assigned) as root.
3. Type: restore
color="#3333ff">4.0.2 Downloading the RPM Format File to
the Target Server
Use this method
to download to an AIX system:
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 /etc/microcode
b) Transfer the RPM
format file to the /etc/microcode directory (using "Save as ...").
You'll
see the filename is scsi.0018.rpm
c) Unpack the file by executing the instructions below:
Enter the commands:
rpm -ihv --ignoreos scsi.0018.rpm
Please verify the file size and checksum of the rpm file.
Filesize: 521122
Checksum: 05883
The microcode files will be added to /etc/microcode/
color="#3333ff">4.0.3 Downloading File from the Microcode 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.
5.0 Microcode Download Procedure-PCI-X Dual Channel Ultra320 SCSI Adapter bus
NOTE: Microcode download must be performed seperately
for each Adapter bus under distinct Logical Partitions (LPAR's).
Please save current and older versions of the microcode update files in
case you need to restore your system.
NOTE: Microcode Download CAN be performed concurrently.
Installation Time: Approximately 30 min System Time.
Procedure:
1. Stop all applications.
2. Enter diag
3. Select the "Task Selection" from diagnostics menu.
4. Select "Microcode Download" from "Task Selection" menu.
5. Select the PCI-X Dual Channel Ultra320 SCSI Adapter
bus that needs to be updated from the list of devices.
6. Select filesystem.
NOTE: If this level of ucode is already installed
in the backplane you will receive a message that will let you know. A message
may also be displayed if the /etc/microcode directory does not have the
previous level microcode. This is true and is not required to complete the
download. Hit enter to continue.
7. The following message will appear
on the screen when download is completed: "The microcode download has completed
successfully, run diagnostics on the SES device". Please ignore the "run
diagnostic" message and do NOT run diagnostics on the SES device at this
time.
8. Return to the Tasks Selection menu and repeat this
procedure for each SES that requires this microcode.
9. Exit diagnostics.
10. For systems that have LPAR installed, the microcode file must be placed on all partitions that have a SES device in order to update the code. Follow this procedure for each partition:
A. Log into the target
partition.
B. Type: cd /etc/microcode
C. FTP to the partition
that has the media bay assigned. (ie. ftp partition1.ibm.com)
D. Type: cd /etc/microcode
E. Type: bin
F. Type: get 44415255.020a0018
G. Type: quit
H. Verify the filesize
and checksum of the file by typing:
1) Filesize: "ls
-l 44415255.020a0018". The filesize should be 600232.
2) Checksum: "sum 44415255.020a0018".
color="#000000"> The checksum should be 32419
color="#000000">.
I. Follow the above procedure to download
the microcode to all PCI-X Dual Channel Ultra320 SCSI Adapter bus' in the
partition.
11. Verify the code level is 0018 by typing "lscfg -vl scsi#" for each scsi device updated. <Where # is the number scsi device>
