    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 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.
