Patent ID: 8751762

Claim:
A system, comprising: a memory; and a processor coupled to the memory, wherein the processor performs operations, the operations comprising: configuring a primary storage controller to communicate with a secondary storage controller via a system data mover; in response to receiving a command to perform a point in time copy of a source volume of the primary storage controller to a target volume of the primary storage controller, determining whether the target volume of the primary storage controller is a source for an asynchronous data replication operation, initiated by the system data mover, between the primary storage controller and the secondary storage controller; and in response to determining that the target volume of the primary storage controller is the source for the asynchronous data replication operation, initiated by the system data mover, performing the point in time copy of the source volume of the primary storage controller to the target volume of the primary storage controller, wherein the command to perform the point in time copy has a parameter that is configurable to indicate that the target volume is to be offline to host systems prior to initiating the point in time copy of the source volume of the primary storage controller to the target volume of the primary storage controller, wherein in response to determining that the target volume of the primary storage controller is the source for the asynchronous data replication operation, initiated by the system data mover, and that the target volume of the primary storage controller is not in use by a host system that is not the system data mover, any configuration of the parameter is ignored.
