Note: For VIOS
systems,
microcode of shared physical I/O resources can only be updated from
VIOS
partition.
To
update disk drive microcode, from VIOS partition, enter the following
command:
oem_setup_env
Then follow the instruction in section 2.3 to transfer/extract the microcode file, and section 2.4.1 to update the disk drive code.
Approximately
20 minutes if using Diagnostics CD; Approximately 5 minutes/drive using
AIX
concurrent diagnostics.
2.2
Determine
Drive Model, FRU&PN and Current Microcode Level
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

microcode level is "P6V3".
Also note that the microcode level "P6V3"
is displayed in “Z1” field.
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 DCHC320.bin
c) Unpack the file by executing the instructions below.
Enter the commands:
cd /tmp/fwupdate
chmod +x DCHC320.bin
./ DCHC320.bin
[Don't overlook the periods (.) in the above command.]
The directory SSD530 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/ DCHC320/* /etc/microcode
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
Enter: mkdir
/tmp/microcode
b)
Transfer the
You'll see the filename is DCHC320-P6V3-AIX.rpm
c)
Unpack the file by executing the instructions below:
Enter the commands:
rpm -ihv
--ignoreos --force DCHC320-P6V3-AIX.rpm
;(please note, there are two dashes)
The
file size and checksum will be verified.
The
microcode files will be added to /etc/microcode/
Copy
microcode updates from the CD-ROM to standard locations on your local
disk:
1.
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.
========================================================
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.

Use similar
steps as above when booting from a Diagnostics CD
======================================================
Microcode can
be updated using the iprconfig
utility. The iprconfig
utility
allows for multiple levels of adapter
and device
microcode to exist on the
system at the same time. After the
device to
update microcode is
selected, all available microcode
levels are
presented to choose to download.
1. If using SLES 9
base, install the package by typing:
rpm -ivh --ignoreos DCHC320-P6V3-LINUX.rpm
2. Update the
microcode by typing:
iprconfig
Press Enter.
3. Select
Download microcode and press Enter.
4. Select the
device you wish to update by typing a 1 then pressing Enter. Multiple
devices
may be selected.
5. Select the
microcode image to be downloaded to the device by typing a 1 then
pressing
Enter.
6. Press Enter again
to confirm the download (display shows “Microcode Download in Progress”
with
elapsed time)
7. If multiple
devices were selected, repeat from Step 5 for the next device.
To check the
microcode level:
1. Start iprconfig utility,
2. Select
"Display hardware status" option.
3. Select disk
to query by typing a 1 next to it and pressing "Enter"
4. Look at the
"Firmware Version" field
