8.3 Restoring System Images

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 "ServerView Resource Coordinator VE Command Reference" for details.

Restoring a System Image

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

1. Put the target server into maintenance mode.

   1. In the RC console resource tree, right-click the target server (physical server, 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 the <OK> button.

      The target server is set to maintenance mode.

2. Restore a system image.

   • To restore the system image from the resource tree:

     1. In the RC console resource tree, right-click the target server (physical server, physical OS or VM host) and select [Backup/Restore]-[Restore] from the popup menu.

        The [Restore] dialog is displayed.

     2. In the [Restore] dialog, select the system image to restore and click the <OK> button.

        The system image is restored.

   • To restore a system image from the [Image List] tab:

     1. In the RC console, click the [Image List] tab.

        The System Image List is displayed.

     2. In the System Image List right-click the system image to be restored and select [Restore] from the popup menu.

        The [Restore] dialog is displayed.

     3. Click the <OK> button.

        The system image is restored.

        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.

3. Release the target server from maintenance mode before resuming its applications.

   1. In the RC console resource tree, right-click the target server (physical server, physical OS or VM host), and select [Maintenance Mode]-[Release] from the popup menu.

      The [Release Maintenance Mode] dialog will be displayed.

   2. Click the <OK> button.

      The target server is released from maintenance mode.

Note

When restoring a VM host in a high-availability configuration (within its virtualization software), all VM guests stored on shared disks should be migrated to another VM host beforehand. The VM host should also be set to maintenance mode within the server virtualization software used before restore.
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 for VM maintenance mode to be set.

After restoring the VM host, migrate back the VM guests to their original VM host.
Refer to the server virtualization software manual and "A.3 Functional Differences between Products" in the "ServerView Resource Coordinator VE Setup Guide" for information on how to migrate VM guests, or details about the VM maintenance mode.
