My problem today is that one of my nodes in my HA cluster (ontap 9.4) owns all SMB-sessions. I do not know why the SVM-server forward all SMB traffic to one of the node. I have two SMB LIF´s, one to each node in the cluster. The DNS (external) is setup an both LIF´s have its own IP address registered in the DNS. When ping from my hyper-V hosts the DNS roundrobin works fine. But it does not matter, when the SVM-server keeps sending all traffic to the same node. If I do a simple filecopy from my hyper-v server to the CIFS-share by using IP-address, then the traffic goes to the correct node.
That is why I want to use Automatic node referrals, to split the load equal over my nodes in the cluster.
Best regards, Pelle Dahlkild
