Abstract:
In one embodiment, a method for switching a storage subsystem in a disaster recovery configuration includes receiving instruction to change from an original target storage subsystem in a disaster recovery configuration including: a source storage subsystem including one or more source volumes from which data is copied in first copy services relationships, the one or more source volumes being accessible to an application, and the original target storage subsystem including one or more original target volumes to which data is copied in the first copy services relationships; selecting a new target storage subsystem to replace the original target storage subsystem, creating second copy services relationships between one or more new target volumes on the new target storage subsystem and the one or more source volumes on the source storage subsystem using multi-target functionality, and terminating the first copy services relationships after all the second copy services relationships are full duplex.
