    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.

    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 R11, R12. The first host adaptor 21 receiving the reserved volume R11, R12 allocation request allocates reserved volume R11 to transfer group TG1, whereby a virtual transfer volume is formed by transfer volume T11 and the reserved volume R11 allocated thereto. As a result, capacity of the virtual transfer volume is increased by the equivalent of the reserved volume R11 capacity, so that additional transfer frames may be stored.

    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 the present invention, when there is a change in a group of volumes managed by a host computer, data duplication processing is immediately carried out against the changed volume. The host computer 10 comprises a volume-managing portion(unit) 12, a data duplication-controlling portion(unit) 11 which executes the data duplication of the data stored in the volume 32 in the main data center 3, and a data duplication storing portion(unit) 13 which stores data necessary for the data duplication. The data duplication-controlling portion 11 compares data held by the volume-managing portion 12 and the data in the data duplication storing portion 13, and updates the data in the data duplication storing portion 13 based on the data held by the volume-managing portion 12.

    摘要: A computer system in which an encryption-decryption process performed by one encryption-decryption module can be moved to another without stopping the process for a read/write request from a host computer. The computer system has a host computer, and a storage system for storing encrypted data. The storage system provides a storage area for accepting access from the host computer. In performing a process for changing the data encrypted and stored by the destination source, the move destination encrypts the data decrypted by the move source which further encrypts and stores the data encrypted by the move destination, and after all data is stored, the move source decrypts and stores the further encrypted data.

    摘要: When migrating data stored in a storage region assigned to a volume to another storage region, the connection status of the host computer and volume is confirmed. When the host computer and volume are connected, the maximum capacity of the volume requested by the host computer is reserved so that it is exclusively secured in another storage region to which data is to be migrated, and when the host computer and volume are not connected, the current capacity of the volume is reserved so that it is exclusively secured in another storage region.

    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.
