Abstract
A clustered computer system, apparatus, program product and method utilize a group member-initiated shutdown process to terminate clustering on a node in an automated and orderly fashion, typically in the event of a failure detected by a group member residing on that node. As a component of such a process, node leave operations are initiated on the other nodes in a clustered computer system, thereby permitting any dependency failovers to occur in an automated fashion. Moreover, other group members on a node to be shutdown are preemptively terminated prior to local detection of the failure within those other group members, so that termination of clustering on the node may be initiated to complete a shutdown operation.
