But I question you're use of a VTS for TSM? There was just a long discussion on this a couple weeks back. Applications that use the entire media (DISP=MOD) like TSM and DFSMShsm are not really good candidates for a VTS. Check out the archives to review the thread. (http://www.adsm.org) When TSM wants to add on to an existing storage pool volume, the existing data must be transferred back into cache in the VTS before it can be appended. Then the 'new' volume has to be staged back to real 3590 tape. The original location on real 3590 is now unavailable and needs to be reclaimed. By doing this a lot, you are forcing the VTS to do a lot of reclamation tasks. Plus the mount wait time to stage the data is holding you up. Unles you write to a volume and mark it as read-only so TSM won't try to append to it again.

Last Week i saw in the Mainvew Monitor an usage off 50 logical drives by TSM ! Is it possible to user more mountpoints, as they are defined by teh mountlimit?
