IBM TSM 7.1 reclamation not working on primary pool - backup

Question

I'm having a problem on IBM TSM 7.1 my test enviroment with primary pool space reclamation.
while there are multiple volumes with reclaimable space i allways get this error:
tsm: SERVER1>reclaim stg stgnasdisk thr=60 dura=60 wait=yes
ANR2111W RECLAIM STGPOOL: There is no data to process for STGNASDISK.
ANS8001I Return code 11.

The reclaim threshold on 100% is normal, this is to prevent reclamation during backup. Reclamation is started daily in the maintanence scipt.
Any help on this is very welcome. I have searched the net but did not really find anything that fixed the issue.

Answer 1

Asked IBM about this issue. TSM needs at least 1 pool without deduplication otherwise it will never reclaim the primary dedup pool even when the data is expired.
On the test envirement i had both the primary and copy pool on deduplication.
I created a non dedup copy pool and reclaims now work normal.
