3. If the blade server boots up far enough to allow the installation of server
4. Recover the system firmware, as described in "Recovering the system
5. After recovering the system firmware, check for and install any server firmware
Recovering the system firmware
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 select Blade Tasks →
Configuration → Boot Mode to show the JS12 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.
See the documentation for the management module to learn more.
Starting the PERM image
You can force the blade server to start the PERM (permanent) image.
