460 IBM BladeCenter JS23 and JS43 Implementation Guide
12.1 Firmware updates
IBM periodically makes firmware updates available for you to install on the IBM
BladeCenter JS23 and JS43 Express, the management module, or expansion
cards in the blade server
IBM BladeCenter JS23 and JS43 Express have a large firmware image, making
it impossible to perform firmware updates through the Advanced Management
Module. For these blade servers, one of the following process should be chosen
to update system’s firmware:
򐂰 In-band operating system capabilities, such as the update_flash command
for Linux and AIX, or the command for Virtual I/O Server.
򐂰 Firmware update function of AIX diagnostics
򐂰 Firmware update function of the stand-alone Diagnostics CD
򐂰 Firmware update function of the IBM Installation Toolkit for Linux (IBMIT) DVD
This section shows in details all steps one needs to accomplish in order to
update IBM BladeCenter JS23 and JS43 Express firmware image.
12.1.1 Commit new firmware to TEMP side
IBM BladeCenter JS23 and JS43 Express hold two firmware images in their
flash, one located in the Temporary (TEMP) side, and the other located in the
Permanent (PERM) side. Firmware updates always take place on the TEMP
side.
Follow the steps below in order to commit a newer firmware image to your IBM
BladeCenter JS23 and JS43 Express:
1. Make sure you are running the firmware locate in the TEMP side. See
“Starting the firmware image from the TEMP side” on page 462 for more
details.
2. Get the your new firmware image from IBM’s web site. See “Get the latest
firmware image from IBM” on page 471 for more details.
Important: Before the installation of the new firmware to the TEMP side
begins, the contents of the TEMP side should be committed to the PERM
side.
The process provides for a
last known good copy of firmware that can be
used if the new image on the TEMP becomes corrupted.
