Protecting a GeoCluster
The GeoCluster Replicated Disk resource allows for the real-time copy of data to be
available on other nodes in the cluster. In the event of a failure and another node takes
ownership, the GeoCluster Replicated Disk resource is also moved to the other node
and it continues to replicate data, in real-time, to the remaining nodes in the cluster.
The instructions for creating this resource are different depending on your operating
system.
