Hello,   Sorry no.  When you rename a volume, you are only renaming the human friendly name.  That's per iSCSI spec, that prevents two duplicate volume names.  So the same applies to replicas.  They can't be renamed. 
Since there isn't a way I have found to modify the replica name on the DR side, I tried renaming the volume to see if it updates the replica set, it does not. Is anyone aware of a way to rename an inbound replica set? Thanks in advance!
