TSM data is not an "ideal" application for a VTS because TSM writes tapes
util they are full, which means anything that gets recalled to the VTS (say
to restore a file) has to bring back the whole "virtual tape", not just the
file you want.

Whether or not you can make it work for you depends on the capacity of your
VTS and your TSM load.

Go to www.adsm.org, search 2001 data for this string: 3494+VTS+TSM
Look for my post from Oct. 31.
