    摘要: A file server device is provided which has less chance of error in changing directory settings information. A file server device that has access to a client computer and a disk array device receives a directory settings file, and writes the directory settings file in a specified shared directory. The file server device chooses, as a migration destination candidate, a volume whose settings information matches new settings information of the shared directory which is set as specified in the directory settings file. The file server device migrates information in the shared directory whose settings information is changed to the volume chosen as a migration destination candidate.

    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 disk control apparatus performing input/output control of data of a storage disk device according to an input/output request from a host includes a cache memory which stores a part of the data and a management table which has format information for indicating whether a track of the storage disk device has been initialized to a predetermined track format for each track of the storage disk device. A control unit creates track format information of the predetermined track format referring to the management table when an input/output request is received from the host. A remote unit transfers initialization information of the management table to another disk control apparatus of a secondary center according to a copy instruction from the host. The control unit updates the format information of the target track in the management table to complete initialization of the target track.

    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.
