Creating a DNS load balancing zone

You can create a DNS load balancing zone to facilitate the dynamic selection of a LIF based on the load, that is, the number of clients mounted on a LIF. You can create a load balancing zone while creating a data LIF.

Before you begin

The DNS forwarder on the site-wide DNS server must be configured to forward all requests for the load balancing zone to the configured LIFs.

The Knowledgebase article How to set up DNS load balancing in Cluster-Mode on the NetApp Support Site contains more information about configuring DNS load balancing using conditional forwarding.

About this task

Procedure

Use the network interface create command with the dns-zone option to create a DNS load balancing zone.
If the load balancing zone already exists, the LIF is added to it. For more information about the command, see the man pages.
The following example demonstrates how to create a DNS load balancing zone named storage.company.com while creating the LIF lif1:
network interface create -vserver vs0 -lif lif1 -role data -home-node node1 
-home-port e0c -address 192.0.2.129 -netmask 255.255.255.128 -dns-zone storage.company.com
