Helllooooo,

The volume replication is for iSCSI and the data replication is for NAS volumes.

Here what I use for the NAS repl.:

Set the Destination Server first.
path : /lv0000/www
share name : /www
Enable the Data replication agent:
CONFIGURATION -> NAS settings -> Function: Data replication agent.
Then enable the Data replication agent for the share:
SETUP -> NAS resources -> Shares -> [share_name] -> Function: Data replication agent settings.


nas1: (Source Server)
path : /lv0000/www
share name : /www

Assign Snapshot to lv0000 (located in Volume Manager)
Go to Maintenance / Backup / Data Replication
Select Snapshot (lv0000)
Set Data Replication schedule (Now, Interval or scheduled)
