DMI creation using CLI

I am creating DMI using CLI as shown below, Am I following the correct syntax?

On the Source Celerra with the hostname EMC-Prod:

nas_cel -interconnect -create Source-To-DR-DMI
-source_server server_2 -destination_system EMC-DR -destination_server
server_2 -source_interfaces ip=x.y.80.25

On the Destination Celerra with the hostname EMC-DR:

nas_cel -interconnect -create DR-To-Source-DMI
-source_server server_2 -destination_system EMC-Prod -destination_server
server_2 -source_interfaces ip=x.y.120.25
