Operating instructions

7.11 Fail-Safe Booter Utility
The fail-safe booter (FSB) is another variant of the SRM console. The
FSB provides an emergency recovery mechanism if the firmware image
contained in flash memory becomes corrupted. You can run the FSB
and boot another image from a CD-ROM or network that is capable of
reprogramming the flash ROM.
Use the FSB when one of the following failures at power-up prohibits you from
getting to the console program:
• Firmware image in flash memory corrupted
• Power failure or accidental power-down during a firmware upgrade
• Error in the nonvolatile RAM (NVRAM) file
• Incorrect environment variable setting
• Driver error
7.11.1 Starting the FSB Automatically
If the firmware image is unavailable when the system is powered on or reset,
the FSB runs automatically.
1. Reset the system to restart the FSB. The FSB loads from the flash.
2. Update the firmware as described in Section 7.11.4.
