摘要： During the normal operation state of a computer system 1000, the data stored in a primary storage system 200P is copied to an intermediate storage system 200I via synchronous copying and the data stored in the intermediate storage system 200I is copied to a secondary storage system 200R via asynchronous copying. During the reverse operation state, however, the data stored in the secondary storage system 200R is copied to the intermediate storage system 200I via asynchronous copying and the data stored in the intermediate storage system 200I is copied to the primary storage system 200P via synchronous copying. In this way, practical remote copying can be carried out in a computer system in which three or more storage devices are installed at different locations and connected serially.

摘要： A remote copy system includes a plurality of storage systems. Each first storage system assigns a sequential number to write data received from the host and sends the write data with the sequential number to the second storage system. One of the first storage systems defers the processing of the write request received from the host and instructs each of the first storage systems to create a marker that includes a sequential number that is a marker number. The second storage systems receive the marker from the first storage system and store the marker number included in the marker.

摘要： During an asynchronous remote copy process for a plurality of asynchronous remote copy pairs, a copy of data in a migration source primary storage area is stored in a migration destination primary storage area, and the copy of data in the migration source primary storage area is also stored in a migration destination secondary storage area through a migration destination primary storage area or a migration source secondary storage area. Then, for an asynchronous remote copy pair established between the migration destination primary storage area and the migration destination secondary storage area together with the above-described asynchronous remote copy pairs, the asynchronous remote copy process is executed in such a method that a copy of writing data is stored in a plurality of secondary storage areas in accordance with the write request sequence issued by a computer. As such, an asynchronous remote copy pair between any two specific storage systems is migrated to be an asynchronous remote copy pair among any other two storage systems.

摘要： A storage system comprises a primary storage device having a primary storage area, a first secondary storage device having a first secondary storage area, and a second secondary storage device having a second secondary storage area. Responsive to host request from a host computer, the primary storage device writes requested host data to the primary storage area. Furthermore the primary storage device sends a first and second copy request to the first and second secondary storage devices, respectively, to store copy data in the first and second secondary storage areas, the first and second copy request containing the copy data which is a copy of the host data. Here the second secondary storage area is identified by a virtual identifier used to identify the second secondary storage area as the virtual storage area within the primary storage device.

摘要： When an event occurs in a storage system that is not recognized by a host, it is not possible to recover data at the point before and after this event. Provided is a storage system including a first storage area storing data to be used by a computer, and a second storage area for storing updated data and its update log information when there is an update request from the computer to the first storage area. This storage system monitors its own storage system and detects an event, and creates a recovery point and its update log information based on the event. When the storage system receives a recovery command at a certain recovery point, it recovers data of the first storage area at the time of recovery point by writing, in a replication storage area at a certain point of the first storage area, update data up to the recovery point among the update data stored in the second storage area.

摘要： A remote copy system includes a plurality of first storage systems and a plurality of second storage systems. Each first storage system assigns a sequential number to write data received from the host and sends the write data with the sequential number to the second storage system. One of the first storage systems defers the processing of the write request received from the host and instructs each of the first storage systems to create a marker, whereupon each of the first storage systems defers the processing of the write request, creates a marker including a sequential number and having a marker number, and sends the marker to the second storage system. Each of the second storage systems, when receiving a marker from the first storage system, stores the marker number included in the marker. One of the second storage systems reads the marker number stored by each of the second storage systems and reports to each of the second storage systems the marker number of smallest value of the marker numbers which were thus read. Each of the second storage systems writes to a logical volume in sequential number order write data, of the write data received from the first storage system, that includes a sequential number of a value smaller than the sequential number of the marker including the marker number reported from one of the second storage systems.

摘要： A storage system includes a plurality of storage apparatuses respectively connected to a host apparatus via a network. A disk controller of each storage apparatus has DKC identifying information for recognizing itself, a logical device identifier created based thereon, and a virtual/logical device identifier set containing a real/logical device identifier and a virtual/logical device identifier. The storage apparatus defined with a pair relationship creates a virtual/logical device identifier set of a mirrored image relationship by replacing its own real/logical device identifier and using it as its own virtual/logical device identifier.
