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.

7. If the last-known functioning configuration does not work, try to recover the system with operating

system recovery software:

o Microsoft® operating systems:

Windows Server® 2003—Automated System Recovery Diskette. If the operating system was

factory-installed, click Start>All Programs>Accessories>System Tools to access the backup utility.

For more information, see the operating system documentation.

Windows® 2000—Emergency Repair Diskette. If the operating system was factory-installed, click

Start>Programs>System Tools to access the Emergency Repair Disk Utility. For more information,

see the operating system documentation.

o Novell NetWare—Repair traditional volumes with VREPAIR. On NetWare 5.X systems, repair NSS

volumes with the NSS menu command, and on NetWare 6 systems, repair NSS volumes using the

NSS/PoolVerify command followed by the NSS/PoolRebuild command, if necessary. For

more information, see the NetWare documentation X.

o Caldera UnixWare and SCO OpenServer from Caldera—Emergency boot diskette. For more

information, see the Caldera UnixWare or SCO OpenServer from Caldera documentation.

o Oracle Solaris—Device Configuration Assistant boot diskette. For more information, see the Oracle

documentation.
