Recovery Disk Usage Instructions

You can use the Recovery Disk to try to recover a system when a system is completely unrecoverable in all other ways.

Recover your System

Before You Begin

Before you begin

We recommend – following the use of the F option – that you perform a server reimage and restore from backup.

Caution

- Do not use the Recovery Disk to switch to a newly upgraded partition for the very first time.

- The F option attempts to fix all file system problems, but it may not fix corruptions every time and may even further corrupt the file system in rare cases. We recommend that you perform a DRS backup.

Procedure

Procedure

Recovery Disk Reference Information

The C option replaces the W option, and performs the same task that W used to perform—it wipes out the hard disks.

The C option is useful if you have 7825/28-H3 servers running with a Release 8.6 (or higher) version of SWRAID. If so, you can perform a fresh install of any version of pre-8.6 Unified Communications Manager by booting your systems with the 8.6 (or higher) version of the Recovery Disk. You must then select option C to clear/wipe out the system.
