To limit tapes, set the maxscratch to the number of tapes you want to use,
make sure to reclaim tapes in the storage pool, and keep the percent
utilization under 30%.  It will work great.

        You need to do colocation. Colocation will place files from each
client on a
        tape by itself providing the client segregation you desire. You can
even
        break this down even further and colocate by filespace. The downside
is that
        you will significantly increase the amount of tapes you use. For
further
        information look in your TSM documentation for "UPDATE STGPOOL".

        -=>
        -=>I am setting up TSM in our shop and I am learning TSM
        -=>as I go. Right now, I have set up a 100GB Disk Pool
        -=>and one Tape Pool and one Tapecopy pool for making
        -=>offsite storage copies.  My questions are:
        -=>
        -=>If I am doing backups using this configuration, my
        -=>daily backups on NT, Netware, and Unix will all first
        -=>go to the disk pool and then migrate to the tape pool.
        -=> Data on the tapes will consist of information from
        -=>all platforms, mixing together, right?  I was
        -=>uncomfortable
        -=>with this data mixing idea.  I called TSM support and
        -=>they assured me everything would be alright.  However,
        -=>If I still want to have tapes consisting of only one
        -=>platform only, are there ways to configure the system
        -=>to do that?  My purpose of doing this is to have NT,
        -=>Novell, and Unix System Administrators to handle their
        -=>own tapes.
        -=>
        -=>Any ideas or suggestions would be greatly appreciated.
