Many questions on: Consistency Groups, Group Sets and SRM.

I am looking at an vSphere environment that utilises RecoverPoint and SRM for D.R failover. (not Recoverpoint for VMs)

The current implementation only uses Consistency Groups. We have one CG per VMWare cluster, each contains Replication Sets for every vSphere datastore in the cluster. Looking to split these CGs down so we have 1 datastore per CG and then group the CGs into Group Sets. The Group Sets will be allocated so that we have one GS per vSphere cluster.

I am struggling to find an answer in any EMC documentation, so I have a few questions:

1. Once we create a Group Set and added CGs to it, can we later remove CGs without affecting the Group Set or replication?
2. Can we failover individual CGs within a Group Set? (the only documentation I can find on this query is answered within the RecoverPoint for VMs admin guide: we do not use this)
   1. If so, what happens to the CG? I assume it is removed from the Group Set (CGs in a Group Set have to all point the same way).
   2. Also if so, once a single CG is failed over, do we have to add it manually back into a Group Set?
3. If one of the CG in a Group Set is in an initialise state, are we still able to fail over the other CGs within the Group Set?
4. Finally – Once configured, will the SRM SRA continue to only see the CGs (same as before) or will it see the Groups Sets too? (I assume same as before)

Any input on these queries would be greatly appreciated.
