摘要:
Even if an arbitrary hard disk drive is added, the hard disk drive is operated in a specific operation mode suited for that hard disk drive. As triggered by attachment of a hard disk drive to a disk adapter, a processor operates the hard disk drive in a predetermined operation mode based on predetermined parameter information that has been prepared in advance. The hard disk drive stores, in advance, particular parameter information including information about the specific operation mode suited for operation. The processor reads the particular parameter information from the hard disk drive in the predetermined operation mode and operates the hard disk drive in the specific operation mode based on the particular parameter information.

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.

Based on information security rules, it is not possible to take out a failure HDD to the exterior of a facility for replacement without erasing data therefrom. According to the present storage sub-system, a slot in which failure has occurred and a slot not registered to a configuration information of a storage sub-system are used to simultaneously perform correction copy to a spare HDD and data erase of the failure HDD in parallel, so as to enable the failure HDD to be brought out to the exterior of the storage facility. Further, time required from when failure has occurred to the HDD to data recovery is shortened, so as to prevent deteriorated redundancy that may be caused by another failure occurring during data recovery and to reduce the risk of data loss.

The difference in the form of connectors connected to data transmission cables is absorbed. A disk array apparatus has a plurality of disk units for executing data input/output processing on storage devices in accordance with a control command from a disk controller; wherein an interface substrate is placed at each disk unit and the interface substrate has a plurality of cable connection connectors to be connected to cables; and a first cable connection connector is connected to a local disk unit, where the relevant connector is placed, via a first data transmission cable; and a second cable connection connector is connected to an adjacent disk unit, which is located adjacent to the local disk unit, or an interface substrate which is placed in the adjacent disk unit, via a second data transmission cable; and these cable connection connectors are configured as connectors in mutually different forms.
