The auxiliary memory which operates data erasure management manner of the auxiliary memory,

摘要

PPROBLEM TO BE SOLVED: To erase data in a storage which composes an auxiliary storage and issue an erasure completion certificate efficiently and reliably regarding a data erasure management method, the auxiliary storage, and a remote maintainance apparatus in a system comprising the auxiliary storage operating by combining a plurality of storages, and the remote maintenance apparatus. PSOLUTION: The storage for composing the auxiliary storage executes a self-diagnosis when it detects the occurrence of failure, records failure information including a diagnosis result in an internal non-volatile RAM, and reports it to the control section of the auxiliary storage. The control section reports the failure information to the remote maintenance apparatus for separating from other storages. The storage performs initialization and erases data, and reports the completion to the remote maintenance apparatus via the auxiliary storage. The remote maintenance apparatus registers the failure information and information on the completion of data erasure in a database of an erasure management server under the remote maintenance apparatus, issues the data erasure completion certificate of the failed storage according to the registered content, and transmits the certificate to a user side.
