Hi, have you created an interface on the DM, on the same subnet, that your control station ip is on?
Similarly, have you got an interface from the same subnet on both DM's?
Can you share the output of the below command from both sides please:
server_ifconfig server_x -all
(obviously replace the x in server_x, with the data mover you are working on, ie server_2)
My control station and datamover are part of different subnet but as per network team all vlan have trust so they should communicate to each other.
Not sure if I have to make changes on Cisco nexus which is part of this converged vblock
