Abstract: PROBLEM TO BE SOLVED: To provide a method, a system and a program for managing the relationship between one target volume and one source volume.
SOLUTION: By at least one element representing a range of a sequential data unit in a volume, at least one relation item representing one relation, and at least one element pointer associating one element with one relation item, information related to an existing relationship between at least one source volume and one target volume is maintained in a memory. Further, when a new relationship between at least one target volume and at least one source volume is added, a new relation item representing the new relationship is added in the memory. Also, one new element pointer for each element is added so as to associate the new relation item with each element including a data unit included in the new relationship.

Abstract: PROBLEM TO BE SOLVED: To provide a point in time copy of data between a source data storage system and target data storage system. SOLUTION: Information which correlates logical identification of a point in time copy data with the point in time copy data stored in a target and source is established in a target, and the information refers to the data storage system which has the required point in time copy data. A controller of the target accesses the point in time copy data required by the target when a table indicates the required point in time copy data is available at the target, if not, obtains the required point in time copy data from the source via a peer to peer communication link interface.

Abstract: Provided are a method, system, and program for managing a relationship between one target volume and one source volume. Information is maintained in memory on an existing relationship between at least one source volume and at least one target volume, comprising: (i) at least one element, wherein each element represents a range of sequential data units in the volume; (ii) at least one relationship entry, wherein each relationship entry represents one relationship; and (iii) at least one element pointer associating one element with one relationship entry, wherein the data units represented by the element are part of the relationship represented by the relationship entry that the pointer associates with the element. A new relationship between at least one target volume and at least one source volume is added. Further, added is a new relationship entry in the memory representing the new relationship and one new element pointer is added in the memory for each element including data units included in the new relationship to associate the element with the new relationship entry, wherein the data units represented by the element are part of the new relationship.
