摘要： Exclusive control is exercised on access to a storage apparatus in a cluster system conducting system changeover. If a system fault has occurred in an execution system, a heartbeat message to a stand-by system is interrupted. A cluster program in the stand-by system detects a fault in the execution system. The cluster program transmits a request to a path setting program in an FC-SW to change over a disk access path from the execution system. Upon receiving the request, the path setting program rewrites a path management table, intercepts the disk access path from the execution system, and transmits a result of the processing to the cluster program. Upon receiving the result, the cluster program starts a server program. The server program starts business processing from a check point at the time when the business processing is stopped due to occurrence of the fault in the execution system.
