I am just starting with mainframe tape management using SMS and CA-1. We
are running two production servers with Tivoli Storage Manager Version 5,
Release 2, Level 3.0 on the same z/OS 1.4 LPAR.

Our problem is with the Sequential Access Storage Pools on TSM, are not
giving back reclaimable space on our tape pools.
Most of our volumes are reporting volume status full even with reclaimable
space on the volume.
Some of the full volumes are reporting as little as 15% utilization.
We are running reclamation on the Storage Pools but, it is bringing back
one or two volumes available out of over 300 tapes with at least 10%
space.
Does anyone have any experience with a similar problem?

Thank you for your help.
