Updating System Firmware from the AIX Service Aids
Attention:
This method is not recommended for partitioned systems, but if the device resources are
allocated 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 be
read.
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 administrator
must 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 the
firmware update using the service aid.
Note: Because the system always reboots itself during this type of firmware update process, the update
process may take up to an hour.
Updating System Firmware from the AIX Command Line
Refer 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 update
process.
Frame (Power Subsystem) Firmware Update
The frame firmware, which includes the power subsystem, is updated using a task on the HMC. Firmware
updates (also called corrective service) are available at
http://techsupport.services.ibm.com/server/mdownload2. If a service representative is installing the
corrective service, the frame firmware download is also available on CORE..
This task downloads a corrective service for the frame onto the HMC.
Note: Because the HMC is a closed system, you cannot install additional applications on your HMC. All of
the tasks you need to maintain the managed system, the underlying operating system, and the
HMC application code are available by using the HMC's management applications.
To download corrective service on the HMC, do the following:
1. From the HMC interface, in the Navigation area (left side of the panel), open the Software
Maintenance folder.
2. In the Contents area (right side of the panel), double-click the Frame icon. The Frame application
opens in the Contents area.
3. In the Contents area, click Receive Corrective Service task.
4. Select one of the following by clicking on the circle to the left.
v Upload corrective service from diskette. If you select this option, make sure the correct diskette
is in the HMC diskette drive.
