<P>PROBLEM TO BE SOLVED: To provide a technique for performing reliable data recovery by rebuild processing without performance deterioration nor cost increases, and allowing continued rebuild processing by skipping errors which can be disregarded, for example, errors in an unused area. <P>SOLUTION: A disk array apparatus 200, when a rebuild error occurs, stores information indicating an error occurrence place in a sector storing unit 203 and stops rebuild processing. A host computer 100, when a rebuild error occurs in the disk array apparatus 200, acquires information indicating an error occurrence place from the disk array apparatus 200. The host computer determines, based on the acquired information indicating the error occurrence place, whether or not the rebuild error is such an error that inhibits continuation of the rebuild processing. If it is determined that the rebuild error does not inhibit continuation of the rebuild processing, the host computer instructs the disk array apparatus 200 to resume the rebuild processing, skipping the error occurrence place. In response to the instruction, the disk array apparatus 200 resumes the rebuild processing, skipping the error occurrence place. <P>COPYRIGHT: (C)2012,JPO&INPIT |
