Ultrix is BSD related, so to read the label you use 'disklabel -r', to edit
the label it's 'disklabel -er' which invokes ed to actually edit the label.
IIRC the default label was / on partition a, swap on b and /usr on g but
it's been a long time since I've used ultrix in anger, probably 8 years or
so. OSF/1 used the same defaults before it morphed into Tru64 V5 and moved
onto SystemV device naming.
