UDP ports
2162/2163 - Array Initialization Utility. Used to discover and initialize new storage systems on the network.
Ports 6390, 6391, and 6392 are typically the destination ports that the array calls back to. Unless an NDU operation was being performed from the command line using EMCRemote, no process would be listening on these ports so they would not show up in a scan. They could also be used and open if a Navisphere 6.x-enabled array was being used as a portal to perform an NDU of a legacy pre-Navisphere 6.x-enabled array.
