That's definitely not the "old school tradition" where we were told to
avoid volser based on real device address. You'd name the volume after
the data or purpose, not on where it is sitting. Today it's probably
less common to find a volume restored on another HDA when you get back
in the office. Since your approach probably will have exceptions too,
you'll have to use the right info anyway (rather than code  'DETACH'
substr(volser,2) for example - the "lookup" stage is your friend for
that...)
