Linking clusters

After the VCS and VVR infrastructure has been set up at both sites, you must link the two clusters. The Remote Cluster Configuration wizard provides an easy interface to link clusters.

To link clusters

1. Verify that the virtual IP address for the ClusterAddress attribute for each cluster is set.

   Use the same IP address as the one assigned to the IP resource in the ClusterService group.

2. If you are adding a cluster to an existing global cluster environment, run the wizard from a cluster in the global cluster environment. Otherwise, run the wizard from any cluster. From Cluster Explorer, click Edit>Add/Delete Remote Cluster.

   SeeAdding a remote cluster.

To configure an additional heartbeat between the clusters (optional)

1. On Cluster Explorer's Edit menu, click Configure Heartbeats.
2. In the Heartbeat configuration dialog box, enter the name of the heartbeat and select the check box next to the name of the cluster.
3. Click the icon in the Configure column to open the Heartbeat Settings dialog box.
4. Specify the value of the Arguments attribute and various timeout and interval fields. Click + to add an argument value; click - to delete it.

   If you specify IP addresses in the Arguments attribute, make sure the IP addresses have DNS entries.

5. Click OK.
6. Click OK in the Heartbeat configuration dialog box.

   Now, you can monitor the state of both clusters from the Java Console:
