4. Reconstruct the logical volume structure if applicable (for example,

using LVM on HP-UX). Use the saved data for the non-root volume
groups (for example, with

vgcfgrestore

or SAM on HP-UX).

5. Additionally, the root volume group to be restored has to be created

on the repaired disk (for example, using

vgimport

on HP-UX). It will

not look like a root volume group during the restore process. This is
because the OS from the auxiliary disk will be running. For more
information on

vgimport

, see its man page.

6. Make the new disk bootable.

7. Reconstruct any other storage structures like mirror, striping, service

guard, and so on from the data saved on a secondary storage device
during backup.

8. Create the filesystems and mount them as required by the data from

the backup; use similar but not the original mountpoint names (like

/etc_restore

for

/etc

, and so on).

9. Remove any files in the mountpoints to be restored, they must be

clean.

10. Start the Data Protector GUI and open a connection to the Cell

Manager. Import the system with the auxiliary disk into the cell.

11. Select the version from which you want to restore. First list all the

required media for the restore and make sure they are available.
Restore all the required mountpoints including the (future)
root-volume to the system, using the option

Restore As

<new_mountpoint>

. The root-volume from the backup is restored to

the root-volume on the repaired disk. Nothing is restored to the
currently-running auxiliary operating system on the auxiliary disk.

12. Shut down the system that was just restored.

13. Disconnect the auxiliary disk from the system.

14. Reboot the system from the new (or repaired) disk.

NOTE

Instead of using an auxiliary disk, the new disk can also be temporarily
connected to a client that has to have a Disk Agent installed. After being
restored, it can be connected to the faulty system and booted.
