摘要： Arrangements for transfer and replication of data. A host computer retains a transfer volume management information including HDD identifiers corresponding to a plurality of primary volumes and identifiers of at least one of transfer volumes, wherein, from a plurality of volumes in a first storage device, the host computer extracts a reserve volume as an additional transfer volume, if a capacity usage of the at least one of the transfer volumes reaches or goes above a predetermined level, wherein the host computer transmits an allocation request about the additional transfer volume, wherein, after receiving the allocation request, the first storage device implements the reserve volume as the additional transfer volume corresponding to the at least one of transfer volumes for transfer of write data to the second storage device.

摘要： To provide a computer system capable of detecting a failure at an early stage while keeping down an increase in I/O load due to failure monitoring. The computer system includes plural storage systems connected in stages between a first computer and a second computer. The first computer sends control I/O to the storage systems. The second computer monitors control I/O transferred through the storage systems; and when there is control I/O that has not been transferred successfully, requests state information of the storage systems to transfer the control I/O.

摘要： The computer system comprises a first and second computer, at least one first storage system connected to the first computer, and a plurality of second storage systems connected to the second computer as well as being connected to the at least one first storage system. The first computer issues to the first storage system a normal write request and control-use write request stamped with issue time. A control-use write request is issued at periodic intervals. The first storage system receives a write request and transmits the write request as update-data to second storage system in such a way that the issue order is ascertainable. The second storage system receives the update-data and, responsive to a reflect instruction from the second computer, reflects the update-data in storage areas. The second computer acquires the issued times stamped on update-data received by the second storage systems, establishes a standard time on the basis of issue times, and instructs the plurality of second storage systems to reflect the update-data whose issue time is at or prior to the standard time in storage areas.

摘要： Transfer of data and replication of data among several storage devices are executed without imposing a load on the computer connected to the storage system. For example, a first host computer monitors usage rates of transfer groups TG11, TG12 and physical path usage rate on a storage device interconnect physical path 50, and when either a usage rate or physical path usage rate goes above a predetermined value, issues to the first storage device 20 an instruction to allocate a reserved volume Ri 1, R12. The first host adaptor 21 receiving the reserved volume Rh, R12 allocation request allocates reserved volume Ru to transfer group TGI, whereby a virtual transfer volume is formed by transfer volume Til and the reserved volume Ru allocated thereto. As a result, capacity of the virtual transfer volume is increased by the equivalent of the reserved volume Ru capacity, so that additional transfer frames may be stored.

摘要翻译： 执行数据传输和数据在多个存储设备之间的复制，而不会在连接到存储系统的计算机上施加负载。 例如，第一主计算机监视存储设备互连物理路径50上的传输组TG 11，TG 12和物理路径使用率的使用率，并且当使用率或物理路径使用率超过预定值时，问题 向第一存储装置20提供分配保留卷Ri 1，R 12的指令。 接收保留卷Rh，R12分配请求的第一主机适配器21分配保留卷Ru以传送组TGI，由此通过传送卷Til和分配给它的保留卷Ru形成虚拟传送卷。 结果，虚拟传送量的容量相当于预留量Ru容量的增加，从而可以存储额外的传送帧。
