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:
Perform a full system backup.
1.
Apply the operating system update, using the instructions provided.
2.
Install the current drivers.
3.
If you apply the update and have problems, refer to the Software and Drivers Download website
(http://h18007.www1.hp.com/support/files/server) to find files to correct the problems.

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.
