Do you have collocation "yes" or "file" ? ? ?
if yes you will have as many filling tapes as clients
if file you will have as many filling tapes as total client file space count
here is an example from one of my tsm servers...
CHIDSM01 Tue Oct 10 06:05:43 CDT 2000 You have 281 SCRATCH and 518 PRIVATE
volumes of which 34 are filling, the rest are full.

Subject: TSM Using Scratch instead of Filling Tapes
AIX 4.3.1, TSM 3.7.3.0, IBM3494, (2) IBM3590B1A
Right now I have 50 tapes in my onsite tape pool and 22 of them are in a
'Filling' state. It seems that TSM is more often selecting a scratch tape
instead of a 'Filling' tape. These 'Filling' tapes aren't reclaimed, and I
was trying to consolidate by doing MOVE DATA commands. I would do a MOVE
DATA for a tape that was only <1% used, when that was completed, I issued
another MOVE DATA command for a different tape. The first MOVE DATA called
for a scratch, and the second one did also. Right now I have a limited
number of 3590 tapes and the turn around to get more is a couple weeks. So,
I'm trying to limp along with what I have. Right now my library has 22
'Filling' and 28 'Full' tapes. I can't do my copypool'n or DB backups. If I
do a MOVE DATA on a 'Filling' tape right now, it calls for an existing tape
as output and when done the input tape goes scratch. If I were to issue
anothe r MOVE DATA, it calls for the scratch tape I just freed up wiht the
first MOVE DATA. So, I have to MOVE DATA to get a scratch tape, and then do
a BA STG for my copypool to grab the scratch. Then I can do another MOVE
DATA to free up another scratch tape.
Has anyone seen this type of behavior out of TSM before? Last night before
my nightly backups I had 2 scratch, 20 'Filling' and 28 'Full' tapes in the
library. This morning I have 22 'Filling' and 28 'Full'. Why isn't TSM
calling for 'Filling' tapes instead of scratch?!?!?!?!?!?!
