TSM 5.5 introduced at a later service level the RELABEL option for SCSI 
libraries that is meant exactly for VTLs; when a tape is returned to scratch 
status from being in a storage pool or used as a DB backup tape, the tape is 
relabeled by TSM in a background process automatically if you have that option 
enabled for your SCSI library.

TSM 6.3 introduced a new kind of library, "VTL," which is just like SCSI, 
except that TSM expects things to happen even faster than with physical drives. 
TSM will also define paths and devices automagically with type=VTL, as I 
recall, although that's not a common event for us. You can UPDATE LIBR from 
type=SCSI to type=VTL. 

So, don't define your VTL volumes in your storage pool; let them go out of 
scratch status but have your TSM library defined to relabel them, and get to 
TSM 6.3 if you're not already there.
