Abstract:
1. A computer program product comprising a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising: computer readable program code configured to provide copy services between a first storage system and a third storage system; computer readable program code configured to detect failure and/or unusability of the third storage system; computer readable program code configured to set configuration information of volumes on a second storage system to match volumes on the first storage system; computer readable program code configured to validate a replication of copy services between the first storage system and a second storage system, wherein copy services do not exist between the second storage system and the first storage system prior to detecting the failure and/or unusability of the third storage system; computer readable program code configured to remove a plurality of existing copy relationships between the first storage system and the third storage system; computer readable program code configured to create a plurality of copy relationships between the first storage system and the second storage system that mirror copy relationships previously existing between the first and third storage systems, wherein copy relationships do not exist between the second storage system and the first storage system prior to detecting the failure and/or unusability of the third storage system; and computer readable program code configured to synchronize a plurality of data between the first storage system and the second storage system.
