Abstract
If one of the HDDs of a disk array fails, a disk array controller regenerates the data stored in the failed HDD and stores the regenerated data in another HDD used in place of the failed HDD. To be more specific, the disk array controller checks each of the stripes of the disk areas of the disk array and determines whether each stripe is used by a file system. This determination is based on a disk resource management table. Then, the disk array controller regenerates data by use of RAID technology only for a stripe that has been determined as being used by the file system.
