ADSM 3.1.2 on aix 4.1.5

Which table holds mount information? I have looked and looked but I just can't
see it. I see drive information, but it doesn't say whether the drive has a
tape mounted. I guess I could query procedures and sessions and extract the
info from them, but that is ugly.... It would probably be better to 'query
mount' and parse the data.... But I really would like a table I could select
from.
