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, or in some cases by using the System Erase Utility and reinstalling all system software.
CAUTION:
Perform a backup before running the System Erase Utility. The utility sets the
system to its original factory state, deletes the current hardware configuration information,
including array setup and disk partitioning, and erases all connected hard drives completely.
Refer to the instructions for using this utility.
2.
Be sure the server has adequate resources (processor speed, hard drive space, and memory) for the
software.
3.
Be sure the server ROM is current and the configuration is correct.
4.
Be sure you have printed records of all troubleshooting information you have collected to this point.
5.
Be sure you have two good backups before you start. Test the backups using a backup utility.
6.
Check the operating system and application software resources to be sure you have the latest
information.
