Controlling the NFS mount privilege

You can control the NFS mount privilege for the storage system's volumes by restricting the mount privilege to only the root user using privileged ports.

About this task

Some PC clients and some older implementations of NFS on UNIX workstations use nonprivileged ports to send requests. If you have these clients at your site, disable the mount_rootonly option or upgrade the client software.

Steps

  1. Access the storage system command line through the console or through a Telnet session.
  2. Do one of the following:
    If you want to... Enter the following command...
    Restrict the mount privilege to only the root user using privileged ports (ports 1 through 1,024)
    options nfs.mount_rootonly on
    Allow the mount privilege for all users on all ports
    options nfs.mount_rootonly off
