server system and service processor by installing firmware updates as they become available. Be sure to follow the instructions in this section. Determination of current server firmware levels Complete the following steps to view the current firmware code levels for the blade server and the service processor: 1. Access and log on to the BladeCenter management-module Web interface as described in the For more information, see the Installation and User's Guide for your BladeCenter unit. 2. From the Blade Tasks section, select Firmware VPD. The Blade Server Firmware VPD window contains the build identifier, release, and revision for system and service processor. Compare this information to the firmware information on the IBM Support Web site at http://www.ibm.com/support/. If these two types of information match, then your blade server has the latest firmware code. If these two types of information differ, download the latest firmware code from the IBM Support Web site. Follow the update instructions on the IBM Support Web site. Updating the blade server service processor To apply the latest firmware code for your blade server service processor, flash the service processor. Download the latest firmware code for your integrated systems management processor from the IBM Support Web site at http://www.ibm.com/ support/. Use the BladeCenter management-module Web interface to flash the service processor. Follow the update instructions on the IBM Support Web site. Important: To avoid problems and to maintain proper system performance, always make sure that the blade server firmware code and service processor code levels are consistent for all blade servers within the BladeCenter unit. Update and manage system flash using Linux service aids This section describes how to update and verify the system flash using Linux service aids. Updating the system flash using Linux The Linux service aid for managing the system flash is separate from the operating system installation and is available for download from the following Web site: http://techsupport.services.ibm.com/server/lopdiags/. Note: The update_flash command can only be performed if the update_flash service aid has been installed on the JS20 blade server for the appropriate version of Linux. Complete the following steps to update the system firmware code: 1. Obtain the flash image you want to update and place it in the /etc/microcode directory (create the directory if it does not exist). 2. Issue following command: update_flash -f /etc/microcode/ After the system reboots successfully and once you are satisfied with the functionality of the new image, commit the update using the following Linux command: update_flash -c Chapter 7.
