    Hello,
    i have a TSM Server 6.2.1.0 on o.s. Windows 2008 x64 and i have 6 disk storage pools, all configured in the same way with Next Storage Pool to 6 different tape pools.

    There's a strange thing that happens only in one disk storage pool: when i write into the option file of any client node the INCLUDE statement indicating the management class that goes to disk, they always ask for the tape mount...

    I use the disk mgmt class for little client nodes with little amount of data to back up, while the bigger ones are sent directly to tape using the tape mgmt class. Even if i run a test back up of two or three Gb with no other sessions opened, it writes something on disk and something on a tape.

    All the other disk storage pool don't give this problem.

    Thank you very much for your help.

    Here is the detailed storage pool:

    This looks like to be your problem:

    The copy storage pool is SPTDOM.

    Well...i think you're referring to the second copygroup, that with mgmt class to tape: mgmt class is MC_DOM and tape storage pool is SPTDOM.
    But the mgmt i put in option files is that in the first copygroup, that is MC_DOM_FILES and disk storage pool is SPDDOM.
    It seems like the migration percentage threshold was set at 0, but it's not so... I'm missing something and i don't know what.
    Thanks a lot for helping
