Sun Cluster Data Service for NFS Guide for Solaris OS

Enabling Secure NFS

Use the -o sec=option option of the share(1M) command in the dfstab.resource-name entry to share your file systems securely. See nfssec(5) man pages for details of specific option settings. If the Sun Cluster HA for NFS resource is already configured and running, see How to Change Share Options on an NFS File System for information about updating the entries in the dfstab.resource-name file. Note that the sec=dh option is not supported on Sun Cluster configurations.
