摘要： A storage subsystem that has detected the necessity of the data relocation determines whether the data relocation is possible or not from one storage unit to another within the particular storage subsystem. A virtualization device is notified in the case where the data relocation in the particular subsystem is impossible. The manager of the virtualization device gives an inquiry to the storage subsystems as to whether any one of them can become a relocation destination or not. A storage subsystem determines, based on the related information, whether the data relocation requested is possible or not within the particular storage subsystem. In the case where such a relocation is possible, the copying process is carried out for data relocation from one storage subsystem to another in compliance with an instruction from the virtualization device.
摘要翻译：已经检测到数据重定位的必要性的存储子系统确定数据重新定位是否可能从特定存储子系统中的一个存储单元到另一存储单元。在特定子系统中的数据重定位不可能的情况下，通知虚拟化设备。虚拟化设备的管理者向存储子系统询问它们中的任何一个是否可以成为重定位目的地。存储子系统基于相关信息确定在特定存储子系统内是否可能请求的数据重定位。在可能进行这种重定位的情况下，根据来自虚拟化设备的指令，执行从一个存储子系统到另一个存储子系统的数据重定位的复制处理。

摘要： When a logical volume in a first storage box is transferred to a second storage box, information of an access object such as a network communication protocol possessed by a host which communicates with the first storage box is changed to change a network route for accessing the transferred logical volume. Logical volume transfer is notified from the first storage box to the host by using an ICMP Redirection Error message or the ARP protocol.
摘要翻译：当第一存储盒中的逻辑卷被传送到第二存储盒时，改变与第一存储盒通信的主机所拥有的诸如网络通信协议的访问对象的信息，以改变用于访问所转移的逻辑卷。通过使用ICMP重定向错误消息或ARP协议，将逻辑卷传输从第一个存储盒通知给主机。

摘要： The present invention provides a method for guaranteeing a data consistency among a plurality of storages and sites, when data transfer is performed by asynchronous remote copying from a site including a plurality of storages. When writing is made into a first storage system or a second storage system, the storage system that received the writing transfers the write data to the other storage system within the site by synchronous remote copying. At this timing the first storage system gives the write data information for order assurance. Furthermore, the first or the second storage system transfers the write data and thus given information for order assurance to the third or the fourth storage system by asynchronous remote copying. Furthermore, the third or the fourth storage system which has received the write data transfers to the other storage system within the same site the write data and information for order assurance by synchronous remote copy.

摘要： A remote copy system includes: a first storage system having a first logical volume accompanied with a first plurality of disk drives in the first storage system; a second storage system having a second logical volume, which is a virtual volume not accompanied with a second plurality of disk drives in the second storage system, the virtual volume configuring a first remote copy pair with the first logical volume; and a third storage system having a third logical volume accompanied with a third plurality of disk drives in the third storage system, the third logical volume configuring a second remote copy pair with the virtual volume and storing a copied data of data stored in the first logical volume. If the second storage system receives write data sent from the first storage system to the virtual volume, the second storage system transfers the write data to the third logical volume in the third storage system.
