How to setup VxVM without encapsulating rootdisk

originally by Kristian Ejvind and subsequently modified by Doug Hughes

[Caution: You shouldn't do this unless you know what you are doing. You will not get any support from Sun or Veritas if you do this and something goes wrong.]

And this from Veritas people:
Do not do this!
This is not a supported feature and I would highly advise than you not attempt this on a production system. Rootdg was designed for just that, to encapsulate root. If you really do not wish to encapsulate root then I would advise finding an unused disk - not your boot- disk and creating a rootdg disk group there. May I ask why do you not want to encapsulate root?

However, if you still insist. Here is the procedure:

1. deport all disk groups from both systems
2. install OS, making sure that you have a tiny partition (e.g. a couple of MB on c0t0d0s7) at the end of the disk.
3. install SEVM /VxVM
4. apply VM patches
5. reboot
6. create rootdg by
   #vxconfigd -m disable
#vxdctl init
#vxdg init rootdg
#vxdctl add disk c0t0d0s7 type=simple
#vxdisk -f init c0t0d0s7 type=simple
#vxdg adddisk c0t0d0s7
#vxdctl enable
#rm /etc/vx/reconfig.d/state/install-db

7. reboot
8. Add mirror of rootdg on at least one other disk!
9. import/setup other disk groups
