Reconfiguring or reloading software
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:
Procedure
1.
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,
or, in some cases, by using the 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 that you have printed records of all troubleshooting information you have collected to this
point.
5.
Be sure that 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 that you have the latest
information.
7.
If the last-known functioning configuration does not work, try to recover the system with operating
system recovery software.
