Node shutdown in clustered computer system

Abstract From the Canadian patent

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 …
