Firmware maintenance

HP has developed technologies to help ensure that HP servers provide maximum uptime with minimal
maintenance. Many of these technologies also reduce server management efforts, enabling administrators
to work on issues and resolve problems without taking servers offline.
The process of updating system or option firmware is referred to as a flash process or flashing the ROM.
A firmware or ROM flash removes the existing version of firmware from the ROM and replaces it with a
more recent version.
Update the firmware to do the following:
Support new hardware, such as a processor revision
Support new features
Correct problems in a previous firmware version
Without the correct firmware version, the server and hardware options may not function properly.

Types of ROM

Types of ROMs include:
System ROM (on page 93)
Option ROMs (on page 93)

System ROM

All ProLiant servers have a system ROM.
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.
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
Types of option ROMs include:
Array controller ROMs
Integrated Lights-Out (iLO) ROMs
