If you ask for saveset information (like savetime), you'll get a report
on savesets, not volumes.  Sometimes that's what I want and I
post-process it with a script to find the oldest (or youngest or
whatever) item on the volume.

The only items you can get in a per-volume report are the items at the
top of the list of mminfo fields up until the first blank line.  None of
them appear to be useful as a "oldest saveset" measure.

In some environments the 'labeled' time would be good enough.  But in
others where tapes are pre-labled ahead of time, the gap would be
significant.

Otherwise something like this might be pretty close:

$ mminfo -av -r 'volume,nsavetime,location' | perl -lane 'if (!exists 
$time{$F[0]} or $time{$F[0]}>$F[1]) {$time{$F[0]}=$F[1]};$loc{$F[0]}=$F[2]; 
END{for(sort keys %time){print "$_ ",scalar localtime $time{$_}, " $loc{$_}"}}'
