Even after execution of the

drmsqlrecover

command, you can check integrity from SQL Server

Enterprise Manager.

If

YES

is specified for this option, integrity after recovery will be checked using SQL Server's

DBCC

CHECKDB

. Note also that the

DBCC CHECKDB

execution time heavily depends on the database size,

including the number of indexes in the database and the number of lines per table. For further
information, see the SQL Server online help.

Setting up restoration while cluster resources are online

In a cluster environment using Microsoft Cluster Service or Windows Server Failover Clustering, use
the parameter described below to select whether to enable data restoration while cluster resources
are in the online state.

Table 17 Parameter in init.conf (setting up restoration when the cluster resources are in the online
state)

Specifiable values
(default)

Description

Parameter

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 data restoration while the cluster resources are in the online state for a volume
within a cluster group in a Microsoft Cluster Service or Windows Server Failover Clustering envir-
onment. However, if the cluster software being used is Veritas Cluster Server, data is restored
while cluster resources are in the offline state.
The following table shows the restoration type when the backup is of a file system.
