Configuring remote cluster objects

After you set up the VCS and replication infrastructure at both sites, you must link the two clusters. You must configure remote cluster objects at each site to link the two clusters. The Remote Cluster Configuration wizard provides an easy interface to link clusters.

To configure remote cluster objects

  • Start the Remote Cluster Configuration wizard.

    From Cluster Explorer, click Edit > Add/Delete Remote Cluster.

    You must use the same IP address as the one assigned to the IP resource in the ClusterService group. Global clusters use this IP address to communicate and exchange ICMP heartbeats between the clusters.
