    摘要: A disk array apparatus includes a first converting unit that performs first conversion on storing object data received in a first control unit from a controller to convert the storing object data into data in a second control unit, the controller including a selecting section that selects, on the basis of the access state monitored by a monitoring section, one from the controller and said first converting unit, and a second converting unit that performs, if the controller is selected by the selecting section, a second conversion, different from the first conversion, on the object data to convert the object data managed in the first control unit into the data in the second control unit. With this configuration, the disk array apparatus accomplishes the object to improve the accessibility to different types of storage units that manage data storing in different control units.

    摘要: A disk management method for managing a disk management device for writing and reading data to and from a disk drive in which a recording medium is managed in a first control unit. The disk management method includes an error checking operation for checking an error on the recording medium in the first control unit, an error correction operation for correcting the error detected in the error, an error correcting operation for correcting the error detected in the error checking operation after converting data including the error to the second control unit, a data loss registration operation for registering a region in which data are lost due to an inconsistency between the first control unit and second control unit in a data loss region table, and a data loss recovery operation for recovering the loss of data with reference to the data loss region table.

    摘要: In a disk array system, when a failure occurs in a disk unit under control, a disk controller performs a rebuild process for rebuilding data stored on the faulty disk unit on a spare disk unit (HS). When a rebuild control section accepts an I/O request from a host before completing the rebuild process in all target areas, the rebuild control section specifies a management unit area including a target area of the I/O request and determines whether the rebuild process is completed in the management unit area. If the rebuild process is not completed in the management unit area, the rebuild control section performs the rebuild process in the management unit area by a rebuild process section and rebuilds data on the HS. After that, an I/O request handling section handles the I/O request.

    摘要: A device adaptor that controls a disk, wherein a storage area is divided into a plurality of blocks, detects a block that includes a read error. Next, the device adaptor detects a write omission in blocks that are within a predetermined range from the block that includes the read error. To be specific, the device adaptor reads data from the blocks that are in the vicinity of the block that includes the unrecovered read error in a suspect disk. Next, the device adaptor reads from a redundant disk, data of a block that corresponds to the block that includes the unrecovered read error (data of block “B” in an example shown in FIG. 1) and compares the read data to the data read from the suspect disk to detect the write omission.
