Abstract
A storage apparatus has a physical storage area used by an external apparatus, a drive interface unit, a power supply unit, and a storage controller executing data write processing from the external apparatus to the storage drive and data read processing from the storage drive through the drive interface unit, and a drive control interface unit. The power supply unit inputs power supply information to the drive interface unit. Any one of the processing units acquires the power supply information of the power supply unit through a data network path to the drive interface unit for the data write processing and the data read processing, and determines whether or not a failure occurs in the power supply unit supplying the operation power to the storage drive and the drive interface unit, on the basis of the acquired power supply information.
