    A tad late but here is my promised summary about the problem i had...

    Thanks to the following guys who tried to help me:

    Jeff Woolsey
    Murdock, Matt
    Bhaskara, Srikalyan

    Marble, Jeff R
    Darren Dunham
    Bernd Schemmer

    After Veritas takes Controll about the harddisk my unassigned Slice 7 (about
    35 GB) was not longer visible for later configurations.

    Here is what i have done:

    With
    # vxprint -ht
    i could discover that my Slice7 now named rootdisk7vol
    (That was the Info I had overread ;-))

    The next Steps were:

    Stop the Veritas Volume:
    # vxvol stop rootdisk7vol

    Erase it:
    # vxassist remove volume rootdisk7vol

    After erasing it i could configure my two new volumes:
    # vxassist -b -g rootdg make test1 15g layout=mirror-concat
    # vxassist -b -g rootdg make test2 15g layout=mirror-concat

    At first i thougt i had to create the volumes without the mirror-layout
    because my rootdg was already mirrored. But then it creates only an
    unmirrored volume...

    this showed me the (mirrored) results:
    # vxprint -ht:
        v test1 - ENABLED SYNC 31457280 SELECT -
        fsgen
        pl test1-01 test1 ENABLED ACTIVE 31464192 CONCAT -
        RW
        sd rootdisk-03 test1-01 rootdisk 69644544 31464192 0
        c1t0d0 ENA
        pl test1-02 test1 ENABLED ACTIVE 31464192 CONCAT -
        RW
        sd rootmirr-01 test1-02 rootmirr 0 31464192 0
        c1t1d0 ENA

        v test2 - ENABLED SYNC 31457280 SELECT -
        fsgen
        pl test2-01 ENABLED ACTIVE 31464192 CONCAT -
        RW
        sd rootdisk-05 test2-01 rootdisk 101108736 31464192 0
        c1t0d0 ENA
        pl test2-02 test2 ENABLED ACTIVE 31464192 CONCAT -
        RW
        sd rootmirr-05 test2-02 rootmirr 31464192 31464192 0
        c1t1d0 ENA

    Creating the directories:
    # mkdir /test1
    # mkdir /test2

    Adding the following entries to /etc/vfstab:
    /dev/vx/dsk/test1 /dev/vx/rdsk/test1 /test1 ufs 1 yes
    -
    /dev/vx/dsk/test2 /dev/vx/rdsk/test2 /test2 ufs 1 yes
    -

    Creating new filesystem:
    # newfs /dev/vx/dsk/test1
    # newfs /dev/vx/dsk/test2

    Mouting all:
    # mountall
    /dev/vx/rdsk/test1: is logging.
    /dev/vx/rdsk/test2: is logging.

    Many Thanks to this nice "Sunmanagers-institution"
