A 2 GB limit seems a bit restrictive, I wonder if that is a file system
limit on the VTL. My VTL has no such restriction. When I installed my
VTL I did not notice any change in TSM DB size due to an increase in the
number of volumes. The amt of data per volume seems minimal.

Subject: Virtual tape libraries
I have been experimenting with a virtual tape library connected to TSM
(Windows 2k3 5.1.6.3 server)
All seems to work perfectly and TSM is none the wiser. However, The
maximum cartridge size in this virtual library is 2GB. I am currently
using LTO1 and getting upto 100 times this amount of data on one tape.
My database is 56GB and I currently have approx 600 volumes
My question is.. if I were to move to a virtual library and had to
increase the number of my volumes by up to 10 times
What impact would this have on my database ?
Thanks in advance
