Replication Manager - VNXe3100 iSCSI replication session job not working

I'm trying to setup iSCSI remote replication on two VNXe 3100 boxes, running the latest codes.

I've setup everything as described in the admin/product guide of Replication Manager, but i'm not able to start create a Replication Manager Job.

Replication Mnager is at version 5.4.1.0

VNXe3100 is at 2.1.3.16008

Solution enabler is at se7322-WINDOWS-x6

steps taken:

1.) setup a VNXe Replication connection between the two VNXe3100 boxes

2.) created source iSCSI LUN

3.) created a generic iSCSI destination LUN

4.) granted access to the source LUN for my Replication Manager Server/Client virtual machine

5.) setup iSCSI initiator to connect to the target

6.) format and assinged a drive letter to the source LUN (F:\ drive)

7.) fired up RM console and added the virtual machine itself as a RM client (which had the agent installed)

8.) discovered storage on the client (non were discovered, this is how it's supposed to be)

9.) created a application set with the F:\ drive in it

10.) started the "create job" wizzard, using the appliation set

on clicking next on step 10, i get :

Mapping the application set...

and then a dialog box displaying:

The application does not reside on supported storage. Unable to create a job for it.

i'm clueless about a possible cause.
