Modify Grid Network Settings
From OSNEXUS Online Documentation Site
System to System communication typically works itself out automatically but it is recommended that you specify the network to be used for system inter-node communication for management operations. This is done by selecting the 'Preferred Grid IP' in the Storage System Modify dialog by right-clicking on each system in the grid and selecting 'Modify Storage System...'.
Navigation: Storage Management --> Storage System --> Add System to Grid (right click)
