    摘要: Information about remote copy target volumes of other storage systems 2 each having one and the same original volume V1 is registered for each remote copy target volume in advance. When there occurs a failure in a copy source storage system 2, a copy source volume for remote copy target volumes using the storage system 2 having a failure as their copy source is selected newly from the registered copy source volumes, and remote copy is resumed.

    摘要: A method for copying information from a first storage subsystem to a second storage subsystem is disclosed. The first and second storage subsystems are provided in a data storage system. The method comprises transmitting first data block from the first storage subsystem to the second storage subsystem, the first storage subsystem being associated with a first host computer and the second storage subsystem being associated with a second host computer; and transmitting first attribute information from the first storage subsystem to the second storage subsystem without intervention from the first host computer.

    摘要: A method for controlling a storage system including a host computer, and a first and a second storage control apparatuses each receiving a data input/output request from the host computer and executing a data input/output process for a storage device in response to the request, comprises connecting a first communication path between the host computer and the first apparatus; connecting a second communication path between the first apparatus and the second apparatus; receiving by the first apparatus a first data input/output request from the host computer through the first path; when the first apparatus has judged that the first request is not for the first apparatus, transmitting by the first apparatus a second data input/output request corresponding to the first request, to the second apparatus through the second path; and by the second apparatus, receiving the second request and executing a data input/output process corresponding to the second request received.
