Troubleshooting 68
Errors occur after the system software is changed
Action: Change settings to the original configuration. If more than one setting was changed, change the
settings one at a time to isolate the cause of the problem.
Errors occur after an application is installed
Action:
• Check the application log and operating system log for entries indicating why the software failed.
• Check system settings to determine if they are the cause of the error. You may need to obtain the settings
from the server setup utility and manually set the software switches. Refer to the application
documentation, the vendor website, or both.
• Check for overwritten files. Refer to the application documentation to find out which files are added by
the application.
• Reinstall the application.
• Be sure you have the most current drivers.
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 68 )
• Option ROMs (on page 69 )
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.
