Abstract
A network storage system has a structure for notifying the data storage system of a fault in the file server, the storage system having means for sending fault notification data to an external maintenance center. The file server can detect a fault and transmit data regarding the fault to the storage control unit while specifying a predetermined logic unit of the storage control unit, and the storage control unit has a faulty part management table, a function for storing the fault-related data transmitted from the file server unit separately from the data exchanged with the computers, a function for detecting a fault other than the fault in the file server unit and for storing that data in the faulty part management table, and a function for transmitting all or part of the faulty part management table to an external unit.
