摘要： A storage control device for managing data in a storage while maintaining redundancy of the data includes a formatting management table, a formatting processing section, a recovery management table and a recovery processing section. The formatting management table manages a formatted region and an unformatted region in a management target volume. The formatting processing section executes formatting of the unformatted region in the management target volume on the basis of the formatting management table. The recovery management table retains a content of the formatting management table at a point of occurrence of a redundancy restoration event when a redundancy restoration event has occurred during formatting. The recovery processing section executes recovery of a formatted region, which had been formatted at the point of occurrence of the redundancy restoration event, on the basis of the recovery management table in parallel with the formatting.

摘要： A virtual volume control unit allocates, upon detection of a write request for new data in a virtual volume to be accessed, an actual storage space of a physical medium existing in the same storage group to the virtual volume in accordance with volume capacity of the new data. A storage control unit stores the new data as actual data in the actual storage space of the physical medium allocated to the virtual volume. And a restoration control unit causes, upon detection of a fallback in data redundancy in the storage group, the actual data in a stored space among the actual storage spaces in the physical medium that caused the fallback to be preferentially restored in an actual storage space in a destination physical medium with reference to the physical media other than the physical medium that caused the fallback in the storage group.

摘要： A rebuild control unit splits a rebuild process into partial processes and instructs an access processing unit to execute the partial processes. In the rebuild process, data identical to data recorded in a first storage device that constitutes RLU #1 is generated based on data read from, among storage devices constituting RLU #1, storage devices other than the first storage device and written to a spare storage device included in a storage system. Each partial process includes a combination of an operation of reading data from a split range created by splitting a data readout target range into fixed-size intervals and an operation of writing data in another storage device based on the data read from the split range. In response to the instruction from the rebuild control unit to execute the multiple partial processes, the access processing unit executes the instructed partial processes in parallel.

摘要： A storage control apparatus manages a plurality of storage devices which belong to an RLU such that data is made redundant between different storage devices. If a first storage device fails, a rebuild controller executes a rebuild process to store the same data as recorded in the first storage device in a spare storage device. When the rebuild controller executing the rebuild process has failed in reading out data from a second storage device, a data recovery controller restarts the first storage device, and reads out data to be stored in the spare storage device from the restarted first storage device.
