摘要： PROBLEM TO BE SOLVED: To prevent erroneous data transfer by determining the validity of recovery in a storage system wherein a disk device recovers and transfers read data.
SOLUTION: A control device performs read access to the disk device 15, and the disk device 15 returns read data and a recovered read error response. The control device 10 carries out retry by the same command at the first recovered read error and determines the data to be correct when no error occurs, to a read command including the retry. Uncertain data (faked data) at the occurrence of the recovered read error is recovered by the retry of the disk, and correct read data can be transferred to a host.

摘要： PROBLEM TO BE SOLVED: To eliminate data loss in error recovery when a management apparatus manages disk devices different in control unit.
SOLUTION: Data of a disk device D1 for managing/controlling reading and writing by LBA wherein 512 bytes are set as one block are mirrored by a display device D2. A storage management apparatus 10 controls access to the disk devices D1, D2 by LBA wherein 520 bytes are set as one block. A difference of the control units is solved by converting addresses by a control unit conversion part 12. Further when error recovery is executed, an address of an area in which data loss is generated due to exclusion from repair target by address conversion for recovery is registered in a data loss management table 14. In a succeeding patrol, the data loss management table 14 is referred to and an error in the address is reported and recovered to eliminate the data loss.
