16.3 Restore

This section explains how to restore a system image backup.

System images can also be restored using commands.
Refer to "Chapter 4 Image Operations" in the "Reference Guide (Command) VE" for details.

Restoring a System Image

Use the following procedure to restore a system image to a managed server.

Place the target server into maintenance mode.
1. In the ROR console server resource tree, right-click the target server (or its physical OS or VM host) and select [Maintenance Mode]-[Set] from the popup menu.
  The [Set Maintenance Mode] dialog is displayed.
  As the target server is restarted during restoration, all of its applications should be stopped beforehand. When restoring a VM host, all of its VM guests should also be stopped.
2. Click <OK>.
  The target server is placed into maintenance mode.
Restore a system image.
- To restore the system image from the server resource tree:
  1. In the ROR console server resource tree, right-click the target server (or its physical OS or VM host) and select [Backup/Restore]-[Restore] from the popup menu.
    The [Restore] dialog is displayed.
  2. Select the system image to be restored.
  3. Click <OK>.
    Restoration of the system image is started.
    The process status can be checked in the Recent Operations area of the ROR console.
    When <Cancel> is clicked in the Recent Operations area, the confirmation dialog to quit the process is displayed.
- To restore a system image from the [Image List] tab:
  1. In the ROR console, select the [Image List] tab.
    The System Image List is displayed.
  2. Right-click the system image to be restored and select [Restore] from the popup menu.
    The [Restore] dialog is displayed.
  3. Click <OK>.
    Restoration of the system image is started.
    The process status can be checked in the Recent Operations area of the ROR console.
    When <Cancel> is clicked in the Recent Operations area, the confirmation dialog to quit the process is displayed.
    When restoring a VM host, be sure to also restore the VM guest backups that correspond to the restored VM host backup version.
    For details on restoring VM guests, refer to the server virtualization software manual.
Release the target server from maintenance mode before resuming its applications.
1. In the ROR console server resource tree, right-click the target server (or its physical OS or VM host) and select [Maintenance Mode]-[Release] from the popup menu.
  The [Release Maintenance Mode] dialog is displayed.
2. Click <OK>.
  The target server is released from maintenance mode.

Note

If the target VM host is in a high-availability configuration, all VM guests stored on shared disks should be migrated to another VM host beforehand.
During restore, because the target VM host will be automatically set to VM maintenance mode, the VM host should be in a state that allows VM maintenance mode to be set.
After restoring the VM host, migrate the VM guests back to their original VM host.

Refer to the server virtualization software manual and "D.3 Functional Differences between Products" in the "Design Guide VE" for information on how to migrate VM guests, and about the VM maintenance mode.

Even when the restore operation is canceled, the target server cannot be returned to its previous status after the image is deployed.

When the managed server has the following configuration, it may not be possible to perform backup correctly unless the following command is executed before performing backup.
