    • 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.
    • 经由操作员界面从操作者接收规定类型的信息要素的输入。 第一存储系统输出构建远程复制环境所需的第一类型信息元素。 第二存储系统输入包括第一类型信息元素和规定类型信息元素的第二设置信息,使用第二设置信息来执行第二设置,并输出构成远程复制环境所需的第二类型信息元素。 第一存储系统输入包括第二类型信息元素的第一设置信息,并且使用第一设置信息来执行第一设置。 由于在存储系统之间交换构建远程复制环境所需的信息元素的类型,所以由操作者输入的信息元素的类型数量小于构建远程复制环境所需的信息元素的数量。
