Reconfiguring or reloading software
5-3-1
Prerequisites for reconfiguring or reloading software
If all other options have not resolved the issue, consider reconfiguring the system. Before reconfiguring the
system, do the following:
Weigh the projected downtime of a software reload against the time spent troubleshooting intermittent
issues. It might be advantageous to start over by removing and reinstalling the software with issues.
Be sure the server has adequate resources (processor speed, hard drive space, and memory) for the
software.
Be sure the server BIOS is current and the configuration is correct.
Be sure you have printed records of all troubleshooting information you have collected to this point.
Be sure you have two good backups before you start. Test the backups using a backup utility.
Check the operating system and application software resources to be sure you have the latest
information.
If the last-known functioning configuration does not work, try to recover the system with operating
system recovery software. For more information, see the operating system documentation.
5-3-2
Restoring to a backed-up version
If you recently upgraded the operating system or software and cannot resolve the issue, 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 issue, you can restore the current set to be sure you do
not lose additional functionality.
For more information, see the documentation provided with the backup software.
