"Createvvcopy" would allow you to use a physical copy (clone), you would want to use the -s option and keep an intermediate snapshot for later resync.
However I'd look at just using snapshots with "createsv" and a regular "updatevv" to provide the resync, it's much lighter weight, simpler and more efficient than cloning and updatevv will maintain the same WWN between snaps, which will be important for the remount.
