System Firmware Updates
This section provides information and instructions for updating the system firmware. You
may need to perform these steps if you are installing an option or if your support
representative has instructed you to update your firmware.
If the system cannot be powered on, but the service processor menus are available,
see “Updating System Firmware From the Service Processor Menus”.
If the service processor programming has been corrupted, the service processor will
automatically enter recovery mode when power is applied to the system. Recovery
mode is described later in this section.
To check the level of firmware that is currently on the system, see “Determining the
Level of Firmware on the System”.
General Information on System Firmware Updates
All the types of system firmware that can be reprogrammed are updated at the same
time. They are:
v System power control network programming
v Service processor programming
v IPL programming
v Run-time abstraction services
Retain and store the latest firmware diskettes each time the firmware gets updated in
the event that the firmware becomes corrupted and must be reloaded.
Determining the Level of Firmware on the System
The firmware level is denoted by XXYYMMDD, where XX = model designation, YY =
year, MM = month, and DD = day of the release.
The firmware level can be determined by either of the following methods:
v On the AIX command line, by typing:
lscfg -vp|grep -F .CL
A line that begins with ROM level (alterable).. displays the firmware level that is
currently on the system.
v Looking at the top of the service processor main menu.
Updating System Firmware From the Service Processor Menus
This procedure 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.
