    摘要: A storage device system in which migration of data from an existing storage device to a higher-standard storage device is unnecessary, and in which discarding of existing storage devices by the user can be prevented. A CHF 61 receives a Read Capacity command from a new-type storage device 25 (S101). Using LDEV, LUN and other information tables, an LUN 87 is converted into a mapped LDEV (S102). A check is performed to determine whether the LDEV emulation type is read-only, write-only, or read/write (S103). If none of these, a check is performed to determine whether the emulation type is newly created (S104). If newly created, the size of all storage areas of the LDEV are set as the Max LBA in a response to the new-type storage device 25 (S105). If the result of S103 is YES, the size of the user area in the LDEV is set as the Max LBA in a response to the new-type storage device 25 (S106). If not newly created, processing proceeds to the processing of S106.

    摘要: There is provided a data processing system which, from a point of view of increasing process efficiency of the entire data processing system to exhibit a maximum effect, may assign an alias device to a logic device. The data processing system of this invention comprises a host processing device (10) and a storage control device (20) connected thereto via a communication means (50), where the storage control device (20) has a deciding means for deciding, at a time of processing an I/O request of a certain base device, whether there is a need to newly assign an alias device to the base device according to a use situation of a physical device (203). When assignment is decided as necessary, the host processing device (10) is notified of such via the communication means, and the host processing device (10) newly assigns an alias device to the base device when there is the notification from the storage control device (20).

    摘要: In control method and apparatus for data transfer in an external storage subsystem, a disk unit and a control unit interposed between a host channel and a processing unit are provided and data in a variable record length supplied from the host is converted to data in a fixed record length to write it in the disk unit. Final format writing end position information for a logical track and an erase flag indicating whether the erasing is required or not are stored at a portion of a logical track control table which controls a cache memory, for each logical track. In the format writing on the cache memory, the final format writing end position information and the erase flag are updated, and when the data is written into the disk unit from the cache memory by logical track unit, the erase flag is referred and the erasing is performed if it is required. Thus, the area of erasing and the number of times of execution are minimized and the throughput of the data transfer between the processing unit and the rotating storage device is improved.

    摘要: For using a plurality of files contained in one logical device with a plurality of processing systems, sharing of a data storage unit among the plurality of processing systems is realized without need for a host processing system to check use states of the files in a server storage unit. Information concerning extent (extent range) of an input/output processing request issued by a host processor is stored in a control memory incorporated in a control unit for allowing the control unit to make decision as to overlap of the extents of the input/output processings to thereby effectuate exclusive control on an extent-by-extent basis.
