Restoring the system if both hard disk drives fail

If both hard disk drives fail, after replacing the hard disk drives, you must do one of the following:

• Rebuild your system from CD media.
• Rebuild your system by restoring the system from a backup, which may be preferable if you have applications, data, and feature administration that also needs to be restored.

If you choose to restore the system from a backup, after the restore completes and the system starts to reboot, you will see a message similar to the following:

Stale DB, insufficient DB replicas.

Press Ctrl-D to come up normally or enter the root password for maintenance mode.

Use the following procedure to complete the system restore and synchronize the new hard disk drives:

1. Enter the root password to go into maintenance (single-user) mode.
2. At the command prompt, enter mirror_admin detach

   Specify the secondary disk as the disk to detach.

3. To exit single-user mode, press Ctrl+d.
4. At the command prompt, log in as root.
5. Enter stop_vs to stop the voice system.
6. Enter mirror_admin replace

   Specify the secondary disk as the disk to replace.

The system automatically reboots and then starts to synchronize the hard disk drives. The secondary hard disk is partitioned and synchronized to the primary hard disk. It takes approximately 20 minutes for each 10 GB to copy data to the secondary hard disk.
