摘要： A controller for the storage apparatus: creates a second logical volume in a storage area provided by one or more storage devices; stores management information of a snapshot of a first logical volume, which is to be provided to a host computer, in the second logical volume; and reads the management information of a necessary snapshot from the second logical volume to a memory when needed, executes processing using the read management information, and returns the management information, which becomes no longer necessary, from the memory to the second logical volume. When reading the management information of the necessary snapshot from the second logical volume to the memory when needed, the controller changes the number of generations and address range of the snapshot of the management information to be read to the memory according to a generation and address of the snapshot whose management information is required.

摘要： In a storage system having a plurality of storage apparatuses, each of the storage apparatuses stores therein a coupling mode that is information indicative of whether or not to permit setting of a communication path between each of the storage apparatuses and a plurality of other storage apparatuses. A management apparatus is provided to be coupled for communication to each of the storage apparatuses. The management apparatus has a communication path setting part that provides a user interface for setting the communication path. The communication path setting part does not permit setting of the communication path, at the time of setting the communication path, when the coupling modes of both of the storage apparatuses between which the communication path is to be set are set permissible.

摘要： The input of a prescribed type information element is received from an operator via an operator interface. A first storage system outputs a first type information element required to construct a remote copy environment. A second storage system inputs second setting information, which comprises first type information elements and prescribed type information elements, uses the second setting information to execute a second setting, and outputs the second type information element required to construct a remote copy environment. The first storage system inputs first setting information, which comprises the second type information element, and uses the first setting information to execute a first setting. Since the types of information elements required to construct a remote copy environment are exchanged between the storage systems, the number of types of information elements inputted by the operator are less than the number of types of information elements required to construct the remote copy environment.
