STORAGE APPARATUS, CONTROL METHOD, AND CONTROL PROGRAM |
| 摘要 |
A storage-apparatus has a plurality of storage-devices and a controller for controlling data read from and write to the plurality of storage-devices, the controller includes a determination-unit and a restore-processing-unit, when a new storage-device has failed in a non-redundant state being a redundant group state without redundancy, in which some of the storage-devices had failed out of the plurality of storage-devices, the determination-unit configured to determine whether execution of compulsory restore of the redundant group is possible or not on the basis of a failure cause of the plurality of failed storage-devices, and if the determination unit determines that the execution of compulsory restore of the redundant group is possible, the restore-processing-unit configured to incorporate a plurality of storage-devices including a newly failed storage-device in the non-redundant state into the redundant group and to compulsorily restore the storage-apparatus to an available state. |

1. A storage apparatus including a plurality of storage devices, and a controller for controlling data read from the plurality of storage devices and data write to the plurality of storage devices,
the controller comprising: when a new storage device has failed in a non-redundant state being a redundant group state without redundancy, in which some of the storage devices had failed out of the plurality of storage devices, a determination unit configured to determine whether execution of compulsory restore of the redundant group is possible or not on the basis of a failure cause of the plurality of failed storage devices; and if the determination unit determines that the execution of compulsory restore of the redundant group is possible, a restore processing unit configured to incorporate a plurality of storage devices including a newly failed storage device in the non-redundant state into the redundant group and to compulsorily restore the storage apparatus to an available state.
