<p>A disk array apparatus capable of reducing a disk drive fault rate where a time-out failure has occurred is provided.</p><p><Paragraphs id="pa02" num="0002" xmlns:base="http://www.sipo.gov.cn/XMLSchema/base">The disk array apparatus (10) includes: a plurality of disk drives (DRVO - DRV14); and a control unit (20, 30) for performing data input/output processing of the disk drives in response to a data input/output request from a host system (70). The control unit includes: a memory (22, 24) for storing control information for specifying a failure of at least one of the disk drives, and failure information of the faulty disk drive; a circuit for specifying, from the failure information, the disk drive in which a time-out failure has occurred, and for issuing an instruction to retry a control command to the disk drive; and a circuit for outputting a control signal to the faulty disk drive in order to hard reset the disk drive if the disk drive does not recover from the failure.
