摘要： A standard physical medium 1320 as loaded into library unit 1080 even in the absence of any load request from a host computer 1020 is regarded as a spare physical medium 1330 for use when the standard physical medium 1320 is under malfunction, and such medium is put in a spare media storage space 1340 while eliminating issuance of any notice to the host computer 1020. Whereby, in a computer system with redundancy configuration, it becomes possible to prevent the host computer from making use of any spare physical media.

摘要： A disk array apparatus, which has redundant data arranged in a distributing layout by record includes apparatus for speeding up redundant data updating processing during later updating, apparatus and a read head and write head securely mounted on a single actuator. In operation, old parity data is read out by the read head and then is used to generate new, updated parity data. The updated parity data is written into the record where the old parity data was held within one turn of the disk after the old parity data has been read out.

摘要： There is a journal area and one or more logical volumes comprising a first logical volume. The journal area is a storage area in which is stored a journal data element, which is a data element that is stored in any storage area of a plurality of storage areas configuring a logical volume, or a data element that is written to the storage area. A controller has a size receiver that receives a write unit size, which is the size of a write data element received from a computer, and a size setting unit that sets the received write unit size in a memory for one or more logical volumes. The size of a journal data element stored in a journal area based on the set write unit size is the write unit size.

摘要： A storage device system comprises interfaces connected to computers, a plurality of magnetic disks, and a control device that controls the plurality of magnetic disks. When a command from one of the computers instructing a tape library device to load a magnetic tape into a tape device is received by one of the interfaces, the control device selects a storage region that is managed as a virtual tape from among storage regions of the magnetic disks. When one of the interfaces receives an access request from the computer to the tape device, the control device controls to access the storage region selected.

摘要： A data sharing method for use in a computer system provided with a first computer, a second computer and a data storage subsystem for connection with the first and second computers is disclosed. The data storage subsystem has a plurality of memory units and a control unit for controlling the plurality of memory units. The control unit forms a paired state of a first memory unit storing data for use by the first computer and a second memory unit, the paired state being so controlled as to match the contents of the first memory unit and those of the second memory unit. When data used by the first computer are to be used by the second computer, the control unit releases the paired state between the first memory unit and the second memory unit to stop updating of the first memory unit to be reflected in the second memory unit. After that, the control unit re-maps a third memory unit used by the second computer and the second memory unit with each other, and so performs control that the access by the second computer to the third memory unit be made to the second memory unit.

摘要： A method for migrating a block of data within a storage system includes migrating first data stored in a first storage volume of a first storage subsystem to a second storage volume in a second storage subsystem. The first data is a block of data that is presented to a host so that the first data may be accessed by the host. First setting information relating to the first data is copied from a first setting volume to a second setting volume. The first and second setting volumes are provided in the first and second storage subsystems, respectively. The second storage volume is presented to the host, so that the host may access the first data stored in the second storage volume via a communication network.

摘要： An intermediate value derived from old and new data record values or old and new data themselves are sent from a control unit to a disk unit which stores a parity record as information necessary for updating parity. The disk unit reads an old parity record and generates a new value of parity record based on the read old parity and the information received from the control unit. The generated new value is stored in an empty record on the storage medium to which a read/write head is first positioned after the generation of the new value and in which effective data has not been stored. In a disk array system, a time required to update the parity record due to the updating of the data record is reduced and a performance of the storage unit subsystem is improved.
