Updating System Firmware From The Aix Command Line - IBM pSeries 670 Service Manual

Note: Because the system always reboots itself during this type of firmware update process, the update
process can take from twenty to sixty minutes.

Updating System Firmware from the AIX Command Line

Attention: This method is not recommended for partitioned systems, but if the device resources are
allocated properly, the firmware update can be done from the AIX command line.
If the firmware on a partitioned system is being updated:
v One partition running AIX must have service authority.
v All other partitions except the one with service authority must be shut down.
v The partition with service authority must own the device from which the firmware update image will be
read.
v It is also recommended that the partition with service authority have a hard disk.
If the required devices are not in the partition with service authority, the customer or system admistrator
must reassign the appropriate resources to it. This requires rebooting the partition with service authority. To
avoid the resource allocation issues, it is recommended that the service processor menus be used to
update the firmware.
If the firmware on a full system partition is being updated, no special steps are required to perform the
firmware update using the command line.
Refer to the detailed instructions that are provided with the latest image on CORE.
Note: Because the system always reboots itself during this type of firmware update process, the update
process can take from twenty to sixty minutes.
