    • Operation of an environment that supports both host-based replication and array-based replication is realized. According to the present invention, data in the first storage area is copied first to the second storage area using an array-based replication engine. In this case, the execution result of the replication is managed using a flag from which the copy timing can be known. In addition, data in the first storage area is copied to the third storage area using a host-based replication engine, and further, data in the third storage area is copied to the fourth storage area. Then, when data in the second storage area is restored to the first storage area, data in the fourth storage area is returned to the third storage area so that the third storage area has data of the same time as the second storage area (see FIG. 12).

    • The invention provides a technology applicable to technologies other than a main frame technology and monitors data recovery available time while suppressing a monitoring error within a certain range in a storage system that performs Asynchronous Remote Copy among storage devices. A management computer in the storage system stores latest or quasi-latest management data corresponding to data staying in a buffer of the first storage device with temporal information at certain monitoring intervals, calculates an estimated value of the data recovery available time which is time of data stored in the second storage device corresponding to data stored in the first storage device, based on the temporal information stored, and based on a certain management data among earliest or quasi-earliest management data or a number of the data staying in the buffer at the certain time and displays the estimated value on a display section.

    • A management computer collects a usage condition of a volume from a host computer and a storage apparatus at each site, consolidates management thereof, and prevents a volume from duplicating among applications as a copy source. This makes it possible to select a used volume in an application as a copy source without excess or deficiency and to create a copy pair configuration definition without duplication or incompatibility. If a replication environment is constructed in a large-scale storage system, the consolidated management of a usage condition of a volume collected from the host computer and the storage apparatus at each site makes it possible to create a copy pair configuration definition by a task constituted by a plurality of applications.

    • The management burden of a replication administrator is alleviated and the monitoring burden is reduced in a storage system. In a large-scale storage system configured across a plurality of sites, a management computer managing the storage system collects configuration information of a volume group such as the copy pair status information from a host computer of the respective sites including a primary site and a remote site, and analyzes the collected information. When a failure or a disaster occurs and the primary site and the remote site are switched and the management computer detects a change in the configuration of the volume group, and appropriate switches the monitoring configuration upon determining the configuration of the detected change.
    • 减轻了复制管理员的管理负担,降低了存储系统的监控负担。 在跨多个站点配置的大型存储系统中,管理存储系统的管理计算机从包括主站点和远程站点的各个站点的主机计算机收集卷组的配置信息,例如复制对状态信息 网站,并分析收集的信息。 发生故障或发生灾难并且主站点和远程站点被切换并且管理计算机检测到卷组的配置发生变化时,并且在确定检测到的更改的配置时适当地切换监视配置。
