Setting up restoration while cluster resources are online
In a cluster environment using MSCS, you can use the following parameter to specify whether to
enable restoration while the cluster resources are in the online state.
Table 23 Parameter in init.conf (setting up restoration when the cluster resources are in the online
state)
Specifiable values
(default)
DescriptionParameter
ONLINE or OFFLINE
(OFFLINE)
Specify ONLINE if you want to perform restoration while
the cluster resources are in the online state when the restore
command is executed. If nothing or OFFLINE is specified,
restoration will be performed while the cluster resources
are in the offline state.
CLU_MSCS_RE-
STORE
In a cluster configuration, disable maintenance mode for a restoration target cluster disk (referred to
as "A") before performing a restoration. Also, if a cluster disk (A) is mounted to a directory, disable
maintenance mode for the cluster disk in the following situations:
#
• When cluster disks are mounted to directories higher up than the directory mount point for the
cluster disk (A) described above.
• When cluster disks are mounted to the same drive as the directory mount point for the cluster disk
(A) described above.
#: If cluster disks are in maintenance mode, Windows might handle them as disks that have not been
clustered, resulting in the detection of an error.
The following explains the relation between this parameter and the cluster resource status for each
backup target.
• File system
You can perform restoration while the cluster resources are in the online state, for a volume within
a cluster group that has a Microsoft Cluster Service environment. If you are using VCS as the
cluster software, restoration will be performed while the cluster resources are in the offline state.
The following table shows the restoration type when the backup is of a file system.

• SQL Server Database
You can perform restoration while the cluster resources are in the online state, for a user database
in a Microsoft Cluster Service environment. If the restoration target contains a system database
(master, model, msdb, or distribution), the SQL Server service is stopped momentarily. This means
