The default export policy of the SVM root volume must include a rule to allow all clients access through NFS. Without such a rule, all NFS clients are denied access to the SVM and its volumes.
When a new SVM is created, a default export policy (called default) is created automatically for the root volume of the SVM. You must create one or more rules for the default export policy before clients can access data on the SVM.
You should verify that all NFS access is open in the default export policy, and later restrict access to individual volumes by creating custom export policies for individual volumes or qtrees.
