apply to the server you are troubleshooting. Refer to the server documentation for information on

Operating system updates
Use care when applying operating system updates (Service Packs, hotfixes, and patches). Before updating
the operating system, read the release notes for each update. If you do not require specific fixes from the
update, it is recommended that you do not apply the updates. Some updates overwrite files specific to HP.
If you decide to apply an operating system update:
1. Perform a full system backup.
2. Apply the operating system update, using the instructions provided.
3. Install the current drivers.
If you apply the update and have problems, locate files to correct the problems on the HP website
( http://www.hp.com/support ).
Operating system problems
Operating system locks up
Action: Scan for viruses with an updated virus scan utility.
Errors are displayed in the error log
Action: Follow the information provided in the error log, and then refer to the operating system
documentation.
Problems occur after the installation of a service pack
Action: Follow the instructions for updating the operating system (" Operating system updates " on page 84 ).
Restoring to a backed-up version
If you recently upgraded the operating system or software and cannot resolve the problem, you can try
restoring a previously saved version of the system. Before restoring the backup, make a backup of the current
system. If restoring the previous system does not correct the problem, you can restore the current set to be sure
you do not lose additional functionality.
Refer to the documentation provided with the backup software.
When to reconfigure or reload software
If all other options have not resolved the problem, consider reconfiguring the system. Before you take this
step:
1. Weigh the projected downtime of a software reload against the time spent troubleshooting intermittent
problems. It may be advantageous to start over by removing and reinstalling the problem software.
