    • A storage system 1 includes a first storage apparatus 100 and a second storage apparatus 100 communicatively coupled to an external apparatus 300. The first and second storage apparatuses respectively have first and second storage areas VDEVs selectively accessible from the external apparatus, first and second temporary storage areas 113, and remote copy controllers 1122 configured to control data copy process. The storage system includes a data I/O process authority information storage unit LDK storing data I/O process authority information. Either of the remote copy controllers reads the data I/O process authority information and copies according to the data I/O process authority information, to the other storage apparatus, data stored either in the first storage area and the first temporary storage area, or in the second storage area and the second temporary storage area that are included in the storage apparatus to which the remote copy controller belongs.

    • Proposed are a computer system and a storage migration method capable of simplifying the migration process of a storage apparatus while avoiding the performance degradation of the overall system. A management apparatus for managing data migration from a first storage apparatus to a second storage apparatus is provided. The management apparatus acquires apparatus-specific information of the first storage apparatus from the first storage apparatus and notifies the acquired apparatus-specific information to the second storage apparatus, and the second storage apparatus sets, as virtualization information, the corresponding apparatus-specific information of the first storage apparatus notified from the management apparatus to a path connecting a second storage area and a second port associated with the second storage area in the second storage apparatus, and notifies the virtualization information as its own apparatus-specific information to the host computer in response to the configuration information acquisition request from the host computer.
    • 提出了一种能够简化存储设备的迁移过程同时避免整个系统的性能下降的计算机系统和存储迁移方法。 提供一种用于管理从第一存储装置向第二存储装置迁移的管理装置。 管理装置从第一存储装置获取第一存储装置的装置专用信息,并将取得的装置专用信息通知给第二存储装置,第二存储装置将虚拟化信息作为虚拟化信息, 所述第一存储装置从所述管理装置通知连接到所述第二存储装置中的与所述第二存储区域相关联的第二存储区域和第二端口的路径,并且将所述虚拟化信息作为其自身的设备特定信息通知给所述主机, 响应来自主机的配置信息获取请求。
