The system firmware is contained in separate temporary and permanent images in the flash memory of the blade server. These images are referred to as TEMP and PERM, respectively. The blade server normally starts from the TEMP image, and uses the PERM image as a backup. If the TEMP image becomes damaged, such as from a power failure during a firmware update, you can recover the TEMP image from the PERM image.
If your system hangs, access the management module and click PS703 or PS704 blade server in the list of blade servers in the BladeCenter® unit. Click the appropriate blade server and select Permanent to force the system to start from the PERM image.
