A control method for an information storage apparatus has the steps of: providing redundancy of information stored in the information storage apparatus; a redundancy failure recording part recording a record of a redundancy failure in a state recording part, when the failure has occurred in keeping of the redundant state of the information; a redundancy monitoring part reading the record of the redundancy failure from the state recording part the record; and a reporting part reporting the redundancy failure when the record of the redundancy failure is read by the redundancy monitoring part.
