Title: Storage device array system
Inventor: KAWAI TATSUJI
IPC: G06F3/06
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To enable writing to a disk array system in rebuilding operation by reading data out of storage devices other than a storage device which is currently rebuilt and restoring data during the rebuilding operation. SOLUTION: When the rebuilding operation is started, a CPU 5 sets an error correcting circuit 8 to a READ mode, sends a READ request to three HDDs 2 except an HDD to be rebuilt through a SCSI controller 3, and waits for the reading to end. Consequently, data from the three HDDs 2 have errors corrected through the error correcting circuit 8 and are stored in a cache memory 9. Then the error correcting circuit 8 is set to a WRITE mode and a WRITE request is sent to only the HDD 2 to be rebuilt, and the end of the WRITE process of the object HDD 2 is expected. Consequently, the contents of the object HDD 2 can be restored after the correction and fault replacement.
