clustermode dns loadbalancing

Setup DNS loadbalancing clustermode.
The lifs belonging to the same dns-zone should be in the same vserver.
The vserver is in fact the dns-zone.

1. Create vserver
vserver create nfs -rootvolume rootvol -aggregate aggr1_n2 -ns-switch file -nm-switch file -rootvolume-security-style unix

2. net int create -vserver nfs -lif lif1 -role data -data-protocol nfs -home-node cluster1-01 -home-port e0c -address
192.168.0.108 -netmask 255.255.255.0 -status-admin up -dns-zone nfs.learn.netapp.local -listen-for-dns-query true

net int create -vserver nfs -lif lif2 -role data -data-protocol nfs -home-node cluster1-01 -home-port e0c -address
192.168.0.109 -netmask 255.255.255.0 -status-admin up -dns-zone nfs.learn.netapp.local -listen-for-dns-query true

3. In Windows DNS.
DNS -> learn.netapp.local -> new delegation -> nfs -> ip 192.168.0.109 (resolve) -> next -> finish

4. Open cmd tool in Windows.
nslookup nfs

Done.
