Storage device, storage-device management system, and storage-device management method

摘要

A storage device includes a S.M.A.R.T. information processor that periodically diagnoses physical and functional condition of the storage device and stores diagnostic information about the condition of the storage device in a magnetic disk and a storage unit. Upon receiving a request for the diagnostic information from a host computer, the S.M.A.R.T. information processor determines whether the magnetic disk is in standby mode. The S.M.A.R.T. information processor acquires the diagnostic information from the storage unit if the magnetic disk is in standby mode, and notifies the diagnostic information to the host computer.
