Abstract:
A mechanism is provided for creating and managing multiple virtualized remote mirroring session consistency groups. The mechanism virtualizes a single physical session of a remote mirroring storage system so that a user is able to create and manage multiple virtual sessions as if they were storage volumes belonging to different physical sessions. With the mechanism of the illustrative embodiments, failover and failback operations may be performed with regard to a first set of virtual sessions while other virtual sessions continue uninterrupted. Thus, a user is provided with the flexibility to temporarily move, through a selective failover operation, selected application production workloads from production sites to recovery sites while other applications can run continuously at the production site. Later, those failed-over applications may failback to the production site and rejoin the physical session.
