You may add the new server with the new subnet and default gateway and after that go to Settings  > More Configuration  > Routing configuration and add/change default/net routes as necessary.
Hello everybody.  I have here a VNXe 3100 and we are an ISP and needs NFS and iSCSI Storage Servers in different VLAN's and with different IP Subnets.  Example: NFS Server 1: 10.10.1.1/24 VLAN 10 Gateway 10.10.1.254 NFS Server 2: 10.20.1.1/24 VLAN 20 Gateway 10.20.1.254 iSCSI Server 1: 10.30.1.1/24 VLAN 30 Gateway 10.30.1.254  Is that not possible? I can create a Storage Server with a different VLAN and IP but if I would change anything the system says that the IP address is not in the same Subnet as the Default Gateway. And if I change the Default Gateway it would say this will change all Gateways on the Storage Processor.  Thank you very much.  Greetings Martin
