These are the steps to disable VM

These are the steps you need to follow, so that Volume Manager does not
start. Please do the 3 steps for the mirror boot disk as well 
that is, both vx-rootdisk and vx-cxtxdx

1)  boot cdrom -s
   mount the root filesystem

2) touch /a/etc/vx/reconfig.d/state.d/install-db

3) copy /a/etc/system /etc/system.old
   Using * to comment out these 2 drivers.
      rootdev:/pseudo/vxio@0:0
	set vxio:vol_rootdev_is_volume=1

Ensure the vfstab reference the solaris partition, you can do the
following:  (see the /etc/vfstab.prevm for what they used to be - maybe)
	copy /a/etc/vfstab /etc/vfstab.old
	copy /a/etc/vfstab.prevm to /etc/vfstab

	*** NOTE IF you do the edit by hand -get the raw and block devices ***
	*** two disk devices per slice/partition ***

-------------------------------------------------------------------------

To re-encapsulate the system disk

	Format Tags 14 & 15 (usually slices 4 & 5) (seen by prtvtoc) so that 
	they are 0 blocks in size (14 should be the entire disk, 15 about 100MB).
	These are the veritas slices (which may be any set of slices).
	Use either format-partition-'letter'=>label, or setup an output
	from prtvtoc and then use fmthard -s filename device.

	Then go into vxinstall and encapsulate root disk, leave all other
	disks alone, then it will reboot machine twice, then you must
	go into vxdiskadm and setup a mirror for the system disk.

	NOTE: the system disk (primary) is the one the devalias vx-rootdisk
	points to.  Do all actions to this physical drive and then mirror
	to the other vx-ctd.
