Abstract
A storage apparatus includes a drive unit device including multiple storage drives, a drive interface unit and a power supply unit, a storage controller including multiple processing units and a drive control interface unit, a recording part recording whether a relevant data input/output process was successful for each of multiple data paths, and a failure detection unit performing a process which, when one processing unit determines the data input/output process not being performed successfully, determines whether a result of the data input/output process performed by other processing units is recorded in the recording part within a predetermined period of time after an abnormality of the relevant data input/output process is recorded, and, when the first processing unit detecting the abnormality determines that the data input/output process abnormality is recorded, provides an instruction to stop the data input/output processes to the drive unit device in which the abnormality is detected.
