Updating System Firmware from the AIX Service AidsAttention: This method is not recommended for partitioned systems, but if the device resources areallocated correctly, the firmware update can be done using the AIX service aid.Note: This service aid is supported only in online diagnostics.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 beread.v The partition with service authority must have a hard disk.If the required devices are not in the partition with service authority, the customer or system administratormust reassign the appropriate resources to it. This requires rebooting the partition with service authority.If the firmware on a full system partition is being updated, no special steps are required to perform thefirmware update using the service aid.Note: Because the system always reboots itself during this type of firmware update process, the updateprocess may take up to an hour.Updating System Firmware from the AIX Command LineRefer to the detailed instructions that are provided on the website with the latest image.Note: The update process can take up to 60 minutes, and the system reboots itself during the updateprocess.Frame (Power Subsystem) Firmware UpdateThe frame firmware, which includes the power subsystem, is updated using a task on the HMC.
