摘要： For a storage system having plural control units to which plural disk devices are connected, in the method for creating replication in a volume of the disk devices connected to different control units, when receiving update I/O of a replication source during an initial copy for replication, the reflection of update to the replication destination is performed on an extension of the same I/O. When a pair is divided after the completion of copying, the update position is retained on the differential bitmap disposed in the individual control units, and the differential bitmap is merged to one of the control units at a time of resynchronization to perform copy processing.

摘要： The present invention maps an arbitrary number of a plurality of physical devices to each logical device provided for a host as a working unit, considering a priority given to each logical device, each physical device being made up of a plurality of disk devices. This arrangement allows dirty data to be quickly saved to the disk devices in the order of logical device priority in the event of a failure. Furthermore, the present invention preferentially processes a job(s) for an important task(s) in the event of a failure to reduce deterioration of the host processing performance.

摘要： In a storage system having a plurality of control units each connected with a plurality of disk units, it is provided that a replication is created in the volume of the disk units connected to different control units. The replication creation unit of a given control unit creates a replication in the volume of the disk unit connected to other control units in such a manner that the original volume information, the replication volume information in the control unit and information on the other control units are registered as volume pair information. Based on this volume pair information, a replication creation request is transmitted to the other control units.

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： In this invention a logical record represents a record accessed by a HOST computer. A physical record represents a record defined on disk units. Physical records consist of data records and parity records. A data record has a value of a logical record. m data records and n parity records form parity records. Parity records are utilized to recover the contents of the data records which belong to the same parity group. A reduction in the generation times of updated values of parity records is realized. A data value of parity records has an allocated status to a logical record and an unallocated status. When a parity-generation scheduling unit decides generation of updated values of a parity group, it recognizes data records which are unallocated to logical records in the parity groups. Then it searches the logical records which are allocated to data records included in the other parity group. Finally it reallocates the recognized data records to the searched logical records. By reallocating data records to logical records, it becomes possible to reduce the number of the parity groups having data records allocated to logical records with updated values.
摘要翻译： 在本发明中，逻辑记录表示由HOST计算机访问的记录。 物理记录表示在磁盘单元上定义的记录。 物理记录由数据记录和奇偶校验记录组成。 数据记录具有逻辑记录的值。 m个数据记录和n个奇偶校验记录形成奇偶校验记录。 奇偶校验记录用于恢复属于同一奇偶校验组的数据记录的内容。 实现奇偶校验记录更新值的生成时间的减少。 奇偶校验记录的数据值具有逻辑记录和未分配状态的分配状态。 当奇偶校验生成调度单元决定奇偶校验组的更新值的生成时，它识别未分配给奇偶校验组中的逻辑记录的数据记录。 然后，它搜索分配给包括在其他奇偶校验组中的数据记录的逻辑记录。 最后，将识别的数据记录重新分配到搜索到的逻辑记录。 通过将数据记录重新分配到逻辑记录，可以减少具有分配给具有更新值的逻辑记录的数据记录的奇偶校验组的数量。
