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.
Always check the pSeries & RS/6000 Support Web site for the latest firmware images
and update instructions. The Web address is: http://www.rs6000.ibm.com/support/micro
Downloading the firmware update image and update instructions from the Web is
preferred.
If the system is running, but access to the Web is not available, see "System Firmware
Update Using a Locally Available Image" on page 284.
If the system cannot be powered on, but the service processor menus are available,
see "Updating System Firmware From the Service Processor Menus" on page 285.
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" on page 284.
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
It is strongly recommended that you create a set of firmware update diskettes from the
Web site as soon as possible after a system is installed. As noted below, the diskette
images can be downloaded to any personal computer, pSeries, or RS/6000 system with
Internet access. This method is the only way to acquire a set of firmware update
diskettes; they cannot be created by using the service processor menus or by using
AIX.
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.
Download the detailed instructions, as well as the latest flash images, from this Web
site. Before doing a system firmware update, check the Web site for the latest code and
images. Do not attempt a firmware update if you are unsure of the image you have, or
of the procedure required for the update.
