6. Power up the server.
The server generates one long beep and two short beeps to indicate that it is in disaster recovery
mode. If the disk is not in the correct drive, then the system continues to beep until a valid ROMPaq
disk is inserted.
The ROMPaq disk flashes both system ROM images. If successful, a sequence of ascending audible
beeps is generated. If unsuccessful, a sequence of descending audible beeps is generated, and you
must repeat the disaster recovery process.
7. Power down the server.
8. Remove the ROMPaq disk.

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.
Array controller ROMs
Array controllers support Recovery ROM, which is a redundancy feature that ensures continuous system
availability by providing a backup ROM. During the flash process, a new version of the firmware can be
flashed to the ROM while the controller maintains the last known version of the firmware. If the firmware
becomes corrupt, the controller reverts back to the redundant version of the firmware and continues
operating.
NOTE: Storage option ROMs cannot be downgraded with ROMPaq because ROMPaqs have
been retired as a delivery method for storage options.
Lights-Out management ROMs
To perform disaster recovery for RILOE II, iLO, and iLO 2, see the documentation for your particular Lights-
Out management product on the Remote management website (
http://www.hp.com/servers/lights-out ).
