To control the resource, you can bring it online and take it offline. Neither of these
actions trigger failover. They just control the activity of the resource.
Bringing the resource online
The GeoCluster Replicated Disk resource will appear offline after it is created. When
you bring it online, the following actions occur.
1. A Storage Mirroring Recover replication set is created with the same name that
was assigned to the resource.
2. The replication set is connected to all of the possible owners specified in the
resource.
3. A mirror is initiated to create the baseline copy of data from the active node to all of
the possible owners.
4. The drive where the mirrored data is located on each of the possible owners is
made read-only to all other applications except Storage Mirroring Recover.
5. Real-time replication from the active node to all of the possible owners begins.
If you are using Windows 2003, right-click the resource and select Bring online.
If you are using Windows 2008, right-click the resource and select Bring this resource
online.
Taking the resource offline
When you take the GeoCluster Replicated Disk resource offline, the following actions
occur.
1. Real-time replication from the active node to the possible owners stops.
2. The read-only limitation is removed from the corresponding drive letters on the
possible owners.
3. The replication set is disconnected from all of the possible owners.
4. The replication set is deleted.
If you are using Windows 2003, right-click the resource and select Take offline.
If you are using Windows 2008, right-click the resource and select Take this resource
offline.
Note:
If the GeoCluster Replicated Disk Resource is offline, data integrity cannot be
guaranteed on the other nodes in the cluster.
