multiple default gateway on NET APP 2520


Hi everybody,

I am new to NET APP so bear with me.

Let's say we have two LIF:

LIG-MGMT gateway  e0c

LIF-CIF  gateway  e0d

DNS server is 

Which gateway will NET APP use to reach  is it gateway associated with MGMT-LIF or gateway associated with LIF-CIF?






You haven't mentioned ontap version here, b'cos the DNS reachability requirement has changed since 8.3.


Beginning with Data ONTAP 8.3, each Data SVM must be configured with its assigned DNS servers. This includes ensuring that DNS servers configured on the Data SVM are accessible from LIFs hosted by that SVM.


In case the filer is running 8.3 or later, Data SVM can use any available gateway that can reach the DNS server IP?  However, the recommended practice is to use one separate mgmt LIF (data protocol=none) per data SVM to talk to DNS (or other external mgmt services) server.

You can verify the DNS reachability via these commands, try both LIFs.

::> network ping -vserver <vserver> -lif <lif> -destination (DNS IP)
::> dns check -vserver <vsever>
