Abstract:
Exemplary methods, apparatuses, and systems include receiving a command from a recovery manager running on a management server within a first or second datacenter. In response to the command, device identifiers for one or more logical storage devices within the first datacenter are requested. In response to the request, a first device identifier for a first logical storage device within the first datacenter and a peer device identifier for a second logical storage device within the second datacenter are received. Data is replicated from the first logical storage device to the second logical storage device. The first and second logical storage devices are in an active-passive configuration, the first logical storage device storing the replicated data being active and the second logical storage device storing the replicated data being passive. The command with the peer device identifier is sent to the underlying storage.
