ESXi 6 and NetApp Volume Mount Issue

In oue Dev Environment which has 3 ESXi 6 servers that use older NetApp running ontop version 8.x. I created a new volume, granted each host read / write and root access and ensured Unix permission are selected. No matter what I do I get the same error message in VMware "Cannot open file....." I have checked the IP in the export a number of times any they are correct. The vmkernel logs says it was denied by the NFS server but I do not know how. Also the hosts have other Lun mounted from this NetApp alraedy that are working.

You are discussing two different technologies NFS file and iSCSI block!

LUN Access is different to NFS Access!

Do you not have the NetApp Appliance which creates and Maps NFS mounts automatically???

Do you have your NFS config from the filer?

The correct IP address has been specified for the mount eg correct VMKERNEL IP address

Sorry for the confusion, yes I am referring to NFS file access and no we do not have the NetApp plugin installed in vCenter. The version we had previously was not compatibly with the vCenter 6.5 upgrade.

I can dump our export file but cannot post it. I did mirror the same permissions setup as another volume on the NetApp and no go. I know in Ontap 9.x you have a main export for all volumes and also SVM's but do not see any SVM's on this NetApp.

We don't have any issues here! (on ESXi 5.1, 5.5, 6.0, 6.5 or 6.7!)  and we run exclusively NFS on our Filers, because NFS is native to NetApp, not an iSCSI stack ontop of Ontap! (which causes overhead on the Filer CPUs!)
