摘要： There are a loose coupling and a tight coupling as the coupling configurations for a first module and a second module. The loose coupling is a coupling configuration in which the first and second modules are coupled together by way of a front-end path, and the first module is not able to access a second storage resource. The tight coupling is a coupling configuration in which the first and second modules are coupled together by way of a back-end path, and the first module is able to access the second storage resource. A switch from the loose coupling to the tight coupling is performed using the following processing flow without the first and second modules being partitioned into respectively independent storage modules. Specifically, first, the first and second modules are coupled together by way of the back-end path, and next, the first module merges information denoted by second management information from the second storage resource with first management information via the back-end path.
摘要翻译： 作为第一模块和第二模块的耦合配置，存在松耦合和紧耦合。 松耦合是其中第一和第二模块通过前端路径耦合在一起的耦合配置，并且第一模块不能访问第二存储资源。 紧耦合是其中第一和第二模块通过后端路径耦合在一起的耦合配置，并且第一模块能够访问第二存储资源。 使用以下处理流程，从松耦合到紧耦合的切换，而不将第一和第二模块分成独立的存储模块。 具体地说，首先，第一模块和第二模块通过后端路径耦合在一起，接下来，第一模块通过后端路径将来自第二存储资源的第二管理信息所表示的信息与第一管理信息进行合并。

摘要： Both of continuation of a job and response to a system failure caused by a disaster are realized simultaneously at low costs. When a failure in remote copy is reported from storage 103A, host 102A starts the host-based remote copy. At this time, first the remote copy is performed starting from the copy to an unfinished I/O. when it becomes possible to restart the storage-based remote copy, the host 102A first stops issuing an I/O and waits for completion of an outstanding I/O in accordance with a command from management server 104A. Thereafter, the host 102A switches over a remote copy method and restarts the I/O.
