Re: EVA CA DR Group & Tunnel Question

To the best of my understanding, each EVA system selects a controller for replication -this should not have a correlation to the controller selection on the target array (e.g. controller A on EVA_01 -> controller A on EVA_02)

What you would see is all the members of a DR group would change their controller ownership status such that they are all owned by the controller designated for replication. Makes sense?
