    • PROBLEM TO BE SOLVED: To improve the processing performance of a storage system by enabling an external volume to be shared by a plurality of virtualization storage devices each of which is capable of using the external volume through virtualization. SOLUTION: A first virtualization storage device 1 virtualizes and takes in the external storage 3A of the external storage device 3 and provides the external storage to a host 4 as if it is an internal volume. If the load on the first virtualization storage device 1 increases, a second virtualization device 2 is newly introduced (S1) and connected to the storage system (S2A, S2B, S3). When a transition instruction is sent from a management terminal 7 (S5), the external volume 3A about a selected logic volume 1D is shifted from the first virtualization storage device 1 to the second virtualization storage device 2 (S7).

    • PROBLEM TO BE SOLVED: To suppress that a time required for processing of access requirement from a host computer becomes long. SOLUTION: In this data processing system, though all of access control attributes representing writing permission, reading permission and writing inhibition is permitted as an access control attribute settable to an extent provided in a storage device, an access control attribute representing reading inhibition is not supported. When reading requirement is received from a communication device (100A) transmitting the reading requirement of reading target data, the reading target data are read from a reading source extent without retrieving the access control attribute of the reading source extent following the reading requirement from the plurality of access control attributes.

    • PROBLEM TO BE SOLVED: To provide a storage system capable of connecting to a plurality of different types of network, and a method for controlling duplication of a system LU of a storage device controller necessary for the storage system. SOLUTION: In the storage system, a system LU for storing control information in an own storage system, and a user LU for writing write data sent from a high order system can be set in an LDEV of the storage device 300. A management terminal designates the system LU or the user LU for setting a path definition with respect to the LDEV, and a CHN 110 prohibits access from the high order system to the system LU in accordance with a classification specified by the management terminal. A path of the system LU with respect to an LU for backup is automatically defined, and control information stored in the system LU with respect to the LU for backup is backed up.

    • PROBLEM TO BE SOLVED: To provide a storage system by which resources are reduced with a WORM (Write Once Read Many) function achieving.
      SOLUTION: A controller 110 acquires information on a logical unit being writing of interest from a storage section 140 when a writing request is raised from a computer 300, and transmits write disable to the computer 300 when the logical unit is set to the write disable. An interface 200 refers to meta-information stored on a disk device 130 and then acquires the list of files not accessed for a specified period of time, and keeps the logical unit capable of storing the files included in the acquired list of the files. The controller 110 asks the logical unit to store the files included in the list of the files and sets the logical unit storing the files to the write disable for information stored on the storage section 140.
