8. Once the system reboots, update the system firmware images. See “Updating
the system firmware images” for instructions.
Updating the system firmware images
Once the system firmware is updated, the QS22 blade server boots from the new
firmware. However, there are always two copies of the system firmware image on
the blade server:
TEMP This is the firmware image normally used in the boot process. When the
firmware is updated, it is the TEMP image that is replaced.
PERM This is a backup copy of the system firmware boot image. The blade server
only boots from this image if the TEMP image is corrupt. See “Recovering
the system firmware code” on page 66 for further information about how to
recover from a corrupt TEMP image.
Once you have updated the system firmware and booted the blade server, you
should copy the TEMP image to the PERM image. This ensures that the PERM and
TEMP images are at the same revision level. The TEMP and PERM images should
always be at the same revision level.
There are two commands you can use to update an old image on PERM.
v From the Linux prompt issue the following command:
update_flash -c
Note: The script checks whether the board has booted from the TEMP image. If
not, the script does not complete.
v
From the Linux prompt issue the following command:
echo 0 > /proc/rtas/manage_flash
For more information on booting from the TEMP or PERM images, see “Recovering
the system firmware code” on page 66.
Updating the optional expansion card firmware
If you have installed the SAS optional expansion card or a high-speed expansion
card, for example the InfiniBand card, you may have to update the firmware. See
the documentation that comes with the components for instructions about how to
update the firmware.
IBM periodically makes updates available for both SAS and high-speed expansion
cards. These may be downloaded from http://www.ibm.com/support/us/en/.
Integrating the Gigabit Ethernet controller into the BladeCenter
One dual-port Gigabit Ethernet controller is integrated on the blade server system
board. Each controller port provides a 1000-Mbps full-duplex interface connecting to
one of the Ethernet Switch Modules in I/O bays 1 and 2 of the BladeCenter unit,
which enables simultaneous transmission and reception of data on the Ethernet
local area network (LAN).
Each Ethernet-controller port on the system board is routed to a different switch
module in I/O bay 1 or bay 2. The routing from the Ethernet-controller port to the
I/O bay varies according to whether an Ethernet adapter is enabled and the
operating system that is installed. See “Blade server Ethernet controller
