Changes the characteristics of one or more mounted Files-11
    volumes. The SET VOLUME command affects only the node on which
    the command is issued, and will not affect any other nodes, even
    when a volume is mounted on multiple nodes in an OpenVMS Cluster
    configuration.
    If you are not the owner of the volume, requires control access
    to the volume.
