摘要

Provided are a computer program product, system, and method for maintaining inactive copy relationships for secondary storages of active copy relationships having a common primary storage for use in case of a failure of the common primary storage. A plurality of active copy relationships are established, each having a common primary storage and one of a plurality of secondary storages. For each possible pair of secondary storages in the active copy relationships, an inactive copy relationship is established to copy data from a first of the secondary storages in the pair to a second of the secondary storages in the pair. In response to a failure of the common primary storage in the active copy relationship, a new active copy relationship is established having a primary and secondary storages from a selected one of the inactive copy relationships.
