Peter - What stands out in the above message is the very large number
        for total clusters (4248).  I typically see a number like 23
when I perform reclamations.  This is probably at the root of it.

I have yet to see a good definition, though, as to what a "cluster" is in
the TSM server context: the only manual that mentions it is the Messages
manual, and that explains it only as "data objects".  I'm wondering if
you have ended up with a large number of tiny files on the tape due to
a small TSM transaction size in client-server sessions (TXNBytelimit,
TXNGroupmax).  If your database size is modest, you can probably do a
Select on the Contents table and check the reported FILE_SIZE to check
what Aggregate size you are getting.  Regardless, no tape reclamation
should take 4 days.  You may want to check with Tivoli Support as to
what is going on.  If you do, and get some insights from them, please
share with the List.
