Abstract
The present invention provides a system and method for disaster recovery split of a node from a cluster to enable cluster management operations using quorum-based data replication services to continue. A split command is executed on a selected node and a new site list data structure describing the cluster is generated. The site list data structure marks all nodes other than the selected node as ineligible, thereby placing the selected node in quorum.
