6 Troubleshooting Recovering from a failed system ROM upgrade Use redundant ROM or ROMPaq to recover from a system ROM upgrade failure. Redundant ROM recovery When you flash the system ROM, ROMPaq writes over the backup ROM and saves the current ROM as a backup, enabling you to switch easily to the alternate ROM version if the new ROM becomes corrupted for any reason. This feature protects the existing ROM version, even if you experience a power failure while flashing the ROM. When the server boots, the server detects if the current ROM is corrupt. If a corrupt ROM is detected, then the system boots from the backup ROM and sends an alert through POST that the ROM is corrupt. To access the redundant ROM through RBSU: 1. Power the server on. A prompt appears in the upper right corner of the screen. 2. Access RBSU by pressing F9. 3. Select Advanced Options. 4. Select ROM Selection. 5. Select Switch to Backup ROM. 6. Press the Enter key. 7. To exit the current menu, press the Esc key, or to exit RBSU, press the F10 key. The server restarts. If RBSU is inaccessible, then you can switch ROM images by changing the switch settings on the system configuration switch. For more information, see your server documentation. If both ROM images are corrupt, use ROMPaq recovery to reinstall the saved ROM. Redundant ROM recovery if the server does not boot from the redundant ROM To perform this recovery, you must gain access to the server system board maintenance switches. NOTE: Although ROMPaq disaster recovery is supported on HP ProLiant servers, each server has unique directions for powering down, opening the chassis, and locating the system maintenance switch block on the server system board. For server-specific information and warnings, see the server user guide. 1. Power the server off. 2. Enable (turn on) system board maintenance switches 1, 5, and 6. 3. Power the server on. Wait until you hear three long beeps. 4. Power the server off. 5. Disable (turn off) system board maintenance switches 1, 5, and 6. 6. Power the server on. Recovering from a failed option ROM upgrade To recover from an option ROM upgrade failure, use the recovery method that is appropriate to the specific option.
