Cluster Terminology

Cluster states and resource types are described in Understanding Clustering.

• Export - Make a resource inactive on a particular controller.

• Failback - Move from AKCS_OWNER state to AKCS_CLUSTERED state, in which all foreign resources (those assigned to the peer) are exported, then imported by the peer.

• Import - Make a resource active on a particular controller.

• Peer - The other controller in a cluster, sometimes also called the standby controller.

• Rejoin - Retrieve and resynchronize the resource map from the peer.

• Resource - A physical or virtual object present, and possibly active, on one or both controllers.

• Takeover - Move from AKCS_CLUSTERED or AKCS_STRIPPED state to AKCS_OWNER state, in which all resources are imported.
