Abstract
For efficient high availability for a multi-node cluster using a processor device in a computing environment, using duplicate, standby host-bus adaptors (HBAs) for alternate nodes with respect to a node with the duplicate, standby HBAs using duplicate credentials of active HBAs of the node for shutting down the node, taking an active HBA of the node offline, and/or activating one of the alternate nodes. A failed node is shut down by an active one of the plurality of alternate nodes using a fence device, and all jobs of the failed node are taken over by the active node using a shared data structure including SCSI device assignments, SCSI reservations, and required host notifications.
