So just to confirm that you are able to use the FC Target from the DSS V6 with only 1 FalconStor Nodes? I just want to make sure that the 4TB can be seen and used without the Host Multi access from the pool. So if you have 1 WWN entered (not all 4) can the FalconStor use this LUN?

We have not tested with this setup so this is where the investigation begins and typically a when accessing with multiple host you would need some SAN filesystem or a VMware HA setup or MS Cluster. But lets define first if you are able to successfully use the LUN with 1 Node.
