/VOLATILE=level
    /NONVOLATILE (default)

    Specifies whether or not the new key is volatile. If you are
    running the OpenVMS Registry on a standalone OpenVMS system,
    volatile keys are lost when the system reboots. If you are
    running the OpenVMS Registry in an OpenVMS cluster, volatile
    keys are lost when all nodes in the cluster are rebooted.

    The values for level are as follows:

    o  NONE (same as /NONVOLATILE)

    o  CLUSTER
