For example, to copy the image file cp QB-1.9.1-2-boot_rom.bin to /proc/ppc64/rtas/firmware_update enter: cp QB-1.9.1-2-boot_rom.bin /proc/ppc64/rtas/firmware_update shutdown -r now 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 BladeCenter QS21 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 59 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 59. Updating the optional expansion card firmware If you have installed the SAS optional expansion card or the high-speed InfiniBand expansion 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 InfiniBand 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 BladeCenter unit I/O bays 1 and 2 of the BladeCenter H unit or the BladeCenter HT unit. These enable simultaneous transmission and reception of data on the Ethernet local area network (LAN). Chapter 2. Configuring the blade server 23
