Abstract:
Synchronous local and cross-site switchover and switchback operations of a node in a disaster recovery (DR) group are described. In one embodiment, during switchover, a takeover node receives a failover request and responsively identifies a first partner node in a first cluster and a second partner node in a second cluster. The first partner node and the takeover node form a first high-availability (HA) group and the second partner node and a third partner node in the second cluster form a second HA group. The first and second HA groups form the DR group and share a storage fabric. The takeover node synchronously restores client access requests associated with a failed partner node at the takeover node.
