Why would you need to do this? Fairly short number of reasons, I expect. I 
had to do it because we were using *very* small disks (like 4 megs) for 
rootdg and the vxinstall was crapping out in the vxdisksetup. Fortunately, 
this is a requirement for vxvm ver 3.5 only, so chances of needing it much 
longer are remote

    vxconfigd -m disable
    vxdctl init
    vxdg init rootdg
    vxdctl enable
    xdisksetup -i ${pv} privlen=1024
    vxdg -g rootdg adddisk ${pv}=${pv}
    rm /etc/vx/reconfig.d/state.d/install-db # enables vxvm to come up on 
                                             # the next boot (line 61 of 
                                             # vxvm-start)
