Hi Gregor
Do you have any TSM DB Backups from time before you run expiration on
that particular files?  Then, by restoring TSM with that DB backup you
can get access to lost files and their entries in TSM if they not have
been already overwritten on tapes (but as you said there was no
reclamation on that tape yet so it should be still possible).
Good luck!
Krzysztof
