Resumes quota enforcement on a disk volume in the current
    management environment; this applies to each node that has the
    disk mounted.

                                 CAUTION

       To use the DISKQUOTA ENABLE command on a disk that has
       been mounted on multiple nodes in a cluster, you must first
       specify the nodes in the SET ENVIRONMENT command.

    Requires SYSPRV privilege, a system UIC, or ownership of the
    volume.
