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： A copy source storage controller received write data added with a time and issued from a host computer transfers the write data with the time to a copy destination storage controller. If there are a plurality of copy destination storage controllers, a representative copy destination storage controller compares times of write data copied to the plurality of copy destination storage controllers, and writes the write data in copy destination logical volumes in the sequential order of time. The representative copy destination storage controller judges that integrity of the write data is established, if a communication procedure is established with the copy destination storage controller and if the statuses of the copy source/destination logical volumes are coincident. In remote copy which guarantees integrity of write data and traverses a plurality of storage controllers, it is possible to judge at an optional time point whether integrity of write data can be guaranteed.

摘要： There is disclosed a data storage system used in a computer environment where there are plural host computers and plural storage array controllers. When a remote copy is made while assuring the order of writing across plural storage array controllers, one of the host computers gains copy information about all the storage array controllers associated with the remote copy as a representative. The representative one of the storage array controllers collects and stores copy statuses which are individually managed by the storage array controllers for which a remote copy is made. The host computer gains the copy statuses from the representative controller using an instruction to gain the copy statuses.

摘要： A computer system having a plurality of host computers and a storage system is provided which allows any one host computer to perform a global copy operation on any arbitrary or all storage areas in the storage system. To this end, storage areas provided by the disk devices are grouped into groups by allocating group numbers to a plurality of specified storage areas. The copy operation can be performed by specifying desired groups. Each of the groups is made up of sub-groups and the sub-groups are defined for each computer to assure a consistency of copy order of the sub-groups.

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： In a computer system, to enable a second computer to take over control of copying of data within the computer system, from a first computer that normally controls copying of data.The second computer selects from a plurality of storage systems a storage system to be accessed in order to acquire sub system pair information, and acquires sub system pair information from the selected storage system. Based on the acquired sub system pair information, the second computer generates system pair information that includes copy pair information relating to a plurality of storage areas belonging to the plurality of storage systems. The second computer initially selects a storage system directly linked to the second computer, and subsequently sequentially selects a storage system based on the acquired sub system pair information.
