Abstract
Systems and methods in accordance with embodiments are provided for the replication of data from virtual logical units to remote virtual logical units. Change logs can be provided at a primary storage switch including a primary VLU to indicate changes made to the primary VLU between replications. The change log can also be used to resynchronize a member split from the primary VLU during a replication operation. Members can be split from the primary VLU and used in a split virtual logical unit at the primary VLU for replication. The remaining member(s) of the primary VLU can be used to maintain the primary VLU online for host devices during the replication operation. A remote VLU at a remote storage switch can be exported as a physical logical unit to the primary storage switch where it is provisioned for a member of a replication VLU at the primary storage switch.
