Automatic Backup - HP ProLiant BL620c - G7 Server Troubleshooting Manual

A system reboot is required for a ROM upgrade to take effect. For disaster recovery or ROM downgrade
purposes, backups of the most current ROM image are available in either redundant ROM or a ROM
backup.
ProLiant servers support either the redundant ROM feature or the Disaster Recovery feature. Both assist
with the management of system ROM revisions and ensure the proper operation of the platform if a failure
occurs during the firmware upgrade process.
Redundant ROM support
The server enables you to upgrade or configure the ROM safely with redundant ROM support. The server
has a 8-MB ROM that acts as two, separate 4-MB ROMs. In the standard implementation, one side of the
ROM contains the current ROM program version, while the other side of the ROM contains a backup
version.
NOTE:
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.
You can choose which ROM to use in RBSU
Disaster recovery support
The Disaster Recovery feature is supported on servers that do not support Redundant ROM. When a ROM
flash fails or the system ROM becomes corrupted, disaster recovery enables administrators to update the
system ROM with a Systems ROMPaq Diskette or USB key.
To use this feature on supported servers, boot to the appropriate media (ROM flash diskette or USB key)
for the affected platform, and then allow the flash recovery process to complete. Because no video
support exists during this process, the server emits a series of beeps at completion.

Automatic backup

A backup copy of the ROM image existing on the target server is made in the ROM image backup
subdirectory:
\CPQSYSTEM\FWBACKUP\SYSTEM
For additional information, see the HP Online ROM Flash User Guide on the HP website
(http://www.hp.com/support/smartstart/documentation).
Option ROMs
Smart Components for option ROMs provide efficient administration of option ROM upgrades. Types of
option ROMs include:
•
Smart Array storage controller ROMs
•
Lights-Out Management ROM flash components
•
SAS hard drive ROMs
•
NIC firmware
The server ships with the same version programmed on each side of the ROM.
