摘要： A RAID system performs host I/O processing during RAID formatting of a plurality of physical disk drives. The controller executes sequential format processing and one-point format processing. A RAID format writing size (SFS) for sequential format processing is set larger than a RAID format writing size (OFS) for one-point format processing. Delay of host I/O processing is reduced, so that the time required for RAID formatting can be shortened.

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 storage system has a plurality of disk storage devices and a controller for controlling the plurality of disk storage devices, and diagnosis of a write miss to a disk of the disk storage device. The controller for controlling the plurality of disk storage devices attaches an ID to write data, and after write access to the disk drive, the controller reads the write data from the disk drive, and compares the ID of the read data and the attached ID. The controller updates the ID for each write command. Therefore the old write data and the new write data can be identified, accurate diagnosis is possible, and the failure of an individual disk drive can be detected immediately.
