[Users] Lun snapshots by a san

Hello everybody, I have a question, or more precisely information or best practice. I use oVirt 3.1 with an attachment on fiber channel on my SAN. Makes it even the San snapshots that are replicated on a remote site. it's a procedure for adding a new "Storage" Domain to another Data Centers (oVirt) in order to recover the state of a VM snapshoted by the SAN? I've read the documentation on Disaster Recovery but it's for the site-to-site failover (i don't have dual architecture of ovirt) while my demand here is for the state recovered a current domain. And only to export the VM(snapshoted by a san) for restore in the current storage (production). thank you Pierre
