I think we can make a statement that if the system supports DR, then
what we describe about DR procedures with link names apply. The
information that was provided by the hardware writer covers hardware
that Sun manufactures. For non-Sun machines, including laptops, user
should check to make sure that DR is supported in those systems.
This leads me to a related question. Does swapping hardware and then
renaming links limited only to systems that support DR? Do the
procedures apply when you remove and replace NICs, e.g., by turning the
system off? This might be the sense of the procedure in Section 4 ("How
to replace a network card while using link names"), which, in turn, was
based on the current docs.
