Abstract
A method for enabling point-in-time-copy target volumes to be primary volumes in PPRC relationships is disclosed. In one embodiment, such a method includes reserving, on a first storage device, first resources needed to establish a first point-in-time-copy relationship between a first source volume and a first target volume. The method further sends a reservation request to a second storage device to reserve second resources needed to establish, on the second storage device, a second point-in-time-copy relationship between a second source volume and a second target volume. In the event the reservation request is successfully executed, the method establishes the first point-in-time-copy relationship on the first storage device using the first resources, and sends a check-in request to the second storage device to establish the second point-in-time-copy relationship on the second storage device using the second resources. A corresponding system and computer program product are also disclosed.
