Recovering The System Firmware; Starting The Perm Image; Starting The Temp Image - IBM PS703 Service Manual

4. Recover the system firmware, as described in "Recovering the system firmware."
5. After recovering the system firmware, check for and install any server firmware updates.

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 click Blade Tasks → Configuration → Boot
Mode to show the 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.
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.
To force the blade server to start the PERM (permanent) image, complete the following procedure.
1. Access the Advanced Management Module menus.
2. Click Blade Tasks → Configuration → Boot Mode.
3. Click the appropriate PS703 or PS704 blade server in the list of blade servers in the BladeCenter unit.
4. Select Permanent to force the system to start from the PERM image.
See the documentation for the management module to learn more.

Starting the TEMP image

Start the TEMP image before you update the firmware.
Perform the following procedure to start the TEMP image.
1. Access the advanced management module.
See the BladeCenter Management Module Command-Line Interface Reference Guide or the BladeCenter
Serial-Over-LAN Setup Guide for more information.
2. Click Blade Tasks → Configuration → Boot Mode.
3. Click the applicable PS703 or PS704 blade server in the list of blade servers in the BladeCenter unit.
4. Select Temporary to force the system to start from the TEMP image.
5. Restart the blade server.
6. Verify that the system starts from the TEMP image, as described in "Verifying the system firmware
levels" on page 218.
