We are implementing 2 VNX5100 (FC Block) storage system and when configuring Replication Manager 5.3.2 & also 5.4 we are getting the following error during the Job Wizard: "Error... The application does not reside on supported storage. Unable to create a job for it"

The environment looks like this:

2x VNX5100

2x DS-300B FC switches

5 ESX hosts dual FC HBA's connected

1 VMware vCenter virtualized on one of the ESX hosts.

RM Server, Client & Gui has been installed on the vCenter (so no direct FC connection).

See screenshot below... any ideas ?
