Updating System Firmware From the Service Processor Menus
This procedure requires a diskette drive to be installed in the system. This procedure also requires a set of
firmware update diskettes in backup format.
The service processor menus are available while the system is powered off. As a privileged user, from the
service processor main menu, select Service Processor Setup , then select Reprogram Flash EPROM
Menu . The update process requests update diskettes as needed.
Updating System Firmware from the AIX Service Aids
Attention: This method is not recommended for partitioned systems, but if the device resources are
allocated properly, 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
It is 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 administrator
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 service aid.
For information about updating system firmware, refer to the instructions that are provided on the web site
with the latest image.
Note: Because the system always reboots itself during this type of firmware update process, the update
process can take from 20 to 60 minutes.
Updating System Firmware from a NIM Server
Refer to “Running Standalone Diagnostics from a Network Installation Management (NIM) Server with an
HMC Attached to the System” on page 33.
