We had a big problem with reservations that turned out to be caused by
using different versions of Atape across our tsm servers and storage
agents.  As we were working with IBM, we would point out that there was
different versions of Atape across our systems.  They told us there was no
problem with having different versions of Atape  across our systems (all
AIX).  But, the solution that  finally worked was to get all systems to
the same (latest/greatest) Atape.

OK, so the storage agent gets a drive and doesn't appear to release it
when
completed?
TBH - I've only ever had reservation conflicts on windows clients.  You
are
100% sure the paths are correct i.e. drive serial numbers match up on
client
and in the path defs for it?
