Troubleshooting 72
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.
Types of ROM
Types of ROMs include:
•
System ROM (on page 72)
•
Option ROMs (on page 72)
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.
Option ROMs
Types of option ROMs include:
•
Array controller ROMs
•
Integrated Lights-Out (iLO) ROMs
•
Hard drive ROMs
Flashing ROM
The process of upgrading system and option ROMs is referred to as flashing the ROM. A ROM flash uses
software to replace the current system ROM on a target server with a new ROM image. Flash the ROM
to:
•
Support new features
•
Correct problems in a previous ROM version
ROMPaq utility diskette or USB drive key
The bootable ROMPaq diskette or USB drive key contains all the necessary system files, option ROM
image files, and the configuration files required to upgrade the ROM firmware.
This procedure is most effective when flashing the ROM on a small number of servers located in close
proximity.
To flash the ROM using ROMPaq:
1.
Download the system ROMPaq utility diskette or USB drive key for each target server. ROMPaq
downloads are available on the HP website (http://www.hp.com/support
).
2.
Shut down each target server, and then reboot using the correct ROMPaq diskette or USB drive key
for that server.
3.
Follow the interactive session in the ROMPaq utility, and then select the devices to be flashed.
