System Firmware Update Using a Locally Available Image
To update the system firmware using a locally available image, perform the following
steps:
1. Log in as root user.
2. If the directory /tmp/fwupdate does not exist, create it by issuing the following
command:
mkdir /tmp/fwupdate
3. The firmware update file must be written into the /tmp/fwupdate directory on the
system. This can be done by using the ftp command to get the image from an ftp
server or NFS-mounting the directory on the host server, for example.
The firmware update file can also be transferred to the target system by backing up
the image onto diskette from another server and restoring it into the /tmp/fwupdate
directory.
After the firmware update file has been written into the /tmp/fwupdate directory,
verify its existence by entering the following command:
ls /tmp/fwupdate/CM*.img
The update file will have the format CMyymmdd.img. The CM indicates that this is
an update image for a system: yy is the year, mm is the month, and dd is the day of
the update file.
4. After the update file has been written to the /tmp/fwupdate directory, enter the
following commands:
cd /usr/lpp/diagnostics/bin
./update_flash -f /tmp/fwupdate/CMyymmdd.img
Attention: Do not overlook the periods (.) in the commands shown above. AIX
commands are case-sensitive. Type them exactly as shown.
You will be asked for confirmation to proceed with the firmware update and the required
reboot. If you confirm, the system will apply the new firmware, reboot, and return to the
AIX prompt. This may take up to ten minutes depending on the configuration of the
system.
Attention: On some systems, the message
Wait for rebooting before stopping
may display on the system console. Do not turn off the system until the system has fully
rebooted to the AIX login prompt. If a shutdown is necessary at that time, log in as root
user and issue the shutdown command.
While the update is in progress, you will see
Rebooting...
on the display for several
minutes.
The firmware update is complete.
Updating System Firmware From the Service Processor Menus
