System Firmware Update in AIX 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 /tmp/fwupdate directory does not exist, create it by issuing the following command:
mkdir /tmp/fwupdate
3. The firmware update file must be downloaded or copied 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 system.
The firmware updated file can also be transferred to the target system by backing up the image onto
diskettes from another server and restoring it into the
/tmp/fwupdate directory.
After the firmware update file has been downloaded or copied into the /tmp/fwupdate directory, verify
its existence by entering either of the following commands, depending on the name of the update
image:
ls /tmp/fwupdate/RH*.img
or
ls /tmp/fwupdate/3H*.img
The update file will have either the RHyymmdd.img format or the 3Hyymmdd.img format. In both
cases, the Hin the second position indicates that this is an update image for your 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
then either of these commands, depending on the name of the update file:
./update_flash -f /tmp/fwupdate/RHyymmdd.img
or
./update_flash -f /tmp/fwupdate/3Hyymmdd.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.
Update Diskette Images and Instructions
Update diskette images and instructions are available from CORE.
It is strongly recommended that you create a set of firmware update diskettes from CORE as soon as
possible after a system is installed. As noted below, the diskette images can be downloaded to any
