PROBLEM TO BE SOLVED: To switch the connection of a cluster client device to a substitute cluster configuration server device under the leadership of a cluster management server device when the cluster configuration server device has a fault. SOLUTION: A cluster management server device 100 collects previously the information on a cluster client device 310 that is managed by a cluster configuration server device 210. When a fault of the device 210 is detected, the device 100 decides a substitute cluster configuration server device 220 and switches the connection of the device 310 managed by the device 210 to the device 220 to reconfigure a cluster system. Thus, it is possible to reconfigure a cluster system by scattering the load of a cluster configuration server device and also to operate the cluster system without stopping it when the cluster configuration server device has a fault.
