Abstract
Embodiments relate to method and computer program products which prioritize the logical units in a subgroup. Thereafter, in case of abnormal operation of the process for copying the consistency group from primary storage to secondary storage, low priority logical units of the subgroups of the consistency group are not copied from primary storage to secondary storage.
