Abstract:
1. A method, in a data processing system, for adding point-in-time copy relationships to the data processing system, the method comprising: receiving, by a copy services manager, a request to establish a first point-in-time copy relationship; determining, by the copy services manager, whether a first point-in-time target volume is a candidate for a non-continuous synchronous copy volume swap relationship; adding, by the copy services manager, a volume swap relationship between the first point-in-time target volume and a second point-in-time target volume to a volume swap configuration in response to determining that the first point-in-time target volume is the candidate for the non-continuous synchronous copy volume swap relationship; establishing, by the copy services manager, the first point-in-time copy relationship for the first point-in-time target volume in the data processing system; establishing, by the copy services manager, a second point-in-time copy relationship for the second point-in-time target volume in the data processing system; and disabling, by the copy service manager, any continuous synchronous copy requirements of the volume swap relationship between the first point-in-time target volume and the second point-in-time target volume.
