Abstract
A high availability cluster computer system can realize exclusive control of a resource shared between computers and effect failover by resetting a currently-active system computer in case a malfunction occurs in the currently-active system computer. In case a malfunction occurs in a certain system in a cluster, another system in the cluster which has detected the malfunction issues a reset based on a priority to realize failover, in which a standby system takes over the processing of the malfunctioning system when the malfunctioning system is stopped.
