    摘要: Provided is a computer system capable of maintaining consistency of data stored in logical volumes. The computer system includes: a storage system including a disk controller which controls data read/write in a disk drive; and a host computer which transmits a request to the storage system, wherein the disk controller has a control unit and a storage unit, the disk drive has logical volumes which are data storing areas, the host computer sends a request directed to the logical volume and attribute information of the logical volume, the control unit wherein: executes the received request; the control unit stores, in the storage unit, the received attribute information in association with the logical volume; and decides to execute a following request which is made by the host computer to the logical volume in a case where the request meets the attribute information corresponding to the logical volume and is stored in the storage unit.

    摘要: Availability of an information system including a storage apparatus and a computer is improved. First and second storage apparatuses execute remote copy of copying data written into a first primary volume from the computer to a second primary volume, at least one of the first and second storage apparatuses executes local copy of copying the data written into the first or second primary volume in a self-storage apparatus to the corresponding first or second secondary volume, and the computer switches the destination of a write request of the data from the first storage apparatus to the second storage apparatus in case of a failure occurring in the first storage apparatus.
