5.4.3 BladeCenter JS20 firmware (BIOS) There is currently no way to upgrade the firmware (BIOS) of a BladeCenter JS20 without first installing an operating system on the blade server. This is usually not an issue, because newly shipped BladeCenter JS20s already have current firmware installed. For completeness, we explain how to upgrade the firmware of a BladeCenter JS20 after you install an operating system. Upgrading firmware under AIX AIX includes the update_flash utility as part of the AIX diagnostics package. To use the update_flash utility, you must first download the latest firmware from the IBM support Web site. Then transfer it to a disk that is accessible to the operating system running on the BladeCenter JS20. Next, you start the update_flash utility from the directory where the new firmware is located. The update_flash utility requires that you have root privileges. The following example illustrates the usage of update_flash: /usr/lpp/diagnostics/bin/update_flash -f JS1FW419A.IMG In this example, JS1FW419A.IMG is the firmware image that was previously downloaded from the IBM support Web site. The update_flash utility asks you to confirm that you want to update the firmware and then reboot the operating system to perform the actual update. If you subsequently have a problem with the new firmware and want to revert to the previous firmware level, use the following command: /usr/lpp/diagnostics/bin/update_flash -r Alternatively, if you are satisfied with the new firmware, commit the firmware update before you install any future firmware by using this command: /usr/lpp/diagnostics/bin/update_flash -c Upgrading firmware under Linux The mechanism used to update the firmware (BIOS) of the BladeCenter JS20 under the Linux operating system is based on a Linux kernel module called rtas_flash. This kernel module is available in most recent 2.4 kernels and in all 2.6 kernels. All supported Linux distributions for the BladeCenter JS20 include this kernel module. The rtas_flash kernel module creates interfaces for manipulating the flash memory where the firmware is stored in the /proc/ppc64/rtas directory. In most Linux distributions, this kernel module is normally not loaded at system boot. 84 The IBM Eserver BladeCenter JS20
Therefore, the interfaces to manipulate the flash memory are not normally present in /proc/ppc64/rtas. IBM provides a script for Linux called update_flash that uses the interfaces provided by the rtas_flash kernel module. It also supports the same options and syntax as the update_flash utility under AIX. You can obtain the latest version of the update_flash script by installing the diagnostic utilities for Linux on POWER that IBM distributes from the Web at: http://techsupport.services.ibm.com/server/lopdiags Note: Some Linux distributions provide a version of the update_flash script that is not fully functional. Always obtain the latest version of the update_flash script from IBM before you attempt to update firmware. To use the update_flash script, follow these steps: 1. Download the latest firmware from the IBM support Web site. 2. Transfer it to a disk that is accessible to the operating system running on the BladeCenter JS20. 3. Enter the update_flash command from the directory where the new firmware is located. The update_flash command requires that you have root privileges. The following example illustrates the usage of update_flash: /usr/sbin/update_flash -f JS1FW419A.IMG In this example, JS1FW419A.IMG is the firmware image that was previously downloaded from the IBM support Web site. The update_flash utility copies the new firmware image into the kernel and then reboots the operating system to perform the actual firmware update. If you subsequently have a problem with the new firmware and want to revert to the previous firmware level, then use the following command: /usr/sbin/update_flash -r If you are happy with the new firmware, commit the firmware upgrade before you install any future firmware by using the following command: /usr/sbin/update_flash -c 5.4.4 Integrated Systems Management Processor firmware The easiest way to upgrade the firmware of the BladeCenter JS20 Integrated Systems Management Processor (ISMP) is through the Management Module Web interface.
