Hi Richard!
Thank you very much for you reply!
I have created a PMR for this behavior and I'm very curious how IBM will
convince me that this is a feature, rather than a bug!
Kindest regards,

Hi, Eric -
For better or worse, this is "historically normal" behavior for the
product - I see it a lot.
A tape will be busy as output for a client session, or be in the
process of dismounting,
and the server will revert to a scratch tape for the second session
which might
otherwise have used that tape. Future sessions may all be singular, and
the second
tape will simply languish. I have an advisory in ADSM QuickFacts for
administrators
to periodically query for such orphans, as a cause of "tape leak". It
would be nice if
the product better dealt with such tapes, but...
