VMS Help SET, DEVICE, Qualifiers, /PATH  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /PATH=path-description-string

    Specifies a particular route to the device. The path description
    string identifies a path from the host to the device (for
    example, PKA0.2343-A855-BC99-876F or PKC0.5). Wildcard characters
    have no special meaning. The path description may be abbreviated
    to the minimum unique string.

    This qualifier applies only to multipath devices.
