One thing to look at is whether the filling tapes are getting used.
We have had a problem for years with what we call "stuck filling tapes".
These are filling tapes that appear to never, ever get reused. We went
around and
around with support on this issue with no resolution. We finally
decided to just live with it. We wrote a script that looks for filling
tapes that have not been used in the past 7 days, and issue a
movedata on them.
This is the sql we run to identify them.
dsmadmc -se=$tsm \
-id=$adminid \
-password=$adminpwd \
-dataonly=yes \
-tab \
"select volume_name, \
stgpool_name, \
(current_timestamp - last_write_date)days, \
status, \
DEVCLASS_NAME, \
access, \
last_write_date \
from volumes \
where status = 'FILLING' \
and access != 'UNAVAILABLE' \
and cast((current_timestamp - last_write_date)days as
decimal(6,0)) \> 7 \
order by volume_name" \
> $tmpfile3

Why so many filling tapes?

Our TSM system is eating tapes.
We have a very large number of "filling" tapes. I have sorted them by
collocation group, and some collocation groups have as many as 6 tapes
in "filling" status. We only have 4 tape drives, and we never migrate
with more than 2 drives per storage pool, so I cannot understand how we
wound up with more than 2 filling tapes per collocation group.
They are all in readwrite status. There have been no I/O errors that
could explain this.
I could accept 3, and call it one of those things, but 6?
