Zusammenfassung:Provided are a computer program product, system, and method for using inactive copy relationships to resynchronize data between storages. A first and second groups of active copy relationships are established to serially copy data among the storages in the first and second groups, respectively. At least one of the storages in both the first group and the second group comprise overlapping storages that are members of both the first and second groups and at least one of the storages in both the first and second groups comprise non-overlapping storages that are a member of only one of the first and second groups. At least one inactive copy relationship is established having as a source storage one of the non-overlapping storages in the first group and as a target storage one of the non-overlapping storages in the second group.
