OnTap 9.5 4 node cluster SVM NFS lifs

We have a cluster and recently added 2 nodes to cluster (4 nodes total).  We have an svm that supports nfs (vmware) with data lifs for the original 2 nodes.  We'd like to expand the svm across all 4 nodes but want to understand how lifs function on an svm that has access to aggregates on 2 HA pairs.  Do we need an nfs lif per node on the svm?  If we connecting to a datastore on nodes1/2 do we connect to the same lifs when accessing a datastore on nodes3/4?

Here's a good starting point for you.  https://library.netapp.com/ecm/ecm_download_file/ECMLP2496234 . 

 

But yes.  generally you want at minimum 1 lif per node to allow direct access to the volume and not go through the cluster network.

"If we connecting to a datastore on nodes1/2 do we connect to the same lifs when accessing a datastore on nodes3/4? "

 

You can, but you should not. As previously said, 1 LIF per node per SVM.

Kind Regards,

Re: OnTap 9.5 4 node cluster SVM NFS lifs

I suspect in your case, I would do this:

  1. Create a NEW NFS LIF on the two new nodes.
  2. Create a NEW datastore on each of the two new nodes (use VSC and it should mount also)
  3. Mount the new datastores to all ESXi nodes
  4. Use VMware and perform a storage vMotion to the datastores. Here is where you can distribute the VMs across all the nodes.

This is of course a high level overview. There are number of finer details that can/should be interpreted.
