Coordination process restart device and coordination process restart method

In a case where an active system virtual server detects stopping of a heartbeat received from a standby system virtual server, the active system virtual server notifies a coordination apparatus of the detection of the stopping of a heartbeat. In addition, the active system virtual server reports whether or not a service is operating to the coordination apparatus. The coordination apparatus instructs the standby system virtual server to restart the system in a case where the stopping of a heartbeat and the operation of a service are received. The standby system virtual server restarts the service, restarts an operating system, or restarts the operating system in a case where the restart of the service is not successful, in response to an instruction for restarting the system.
