Creating a new volume group using two hard disks:
Code:
mkdir /dev/newvg
mknod /dev/newvg/group c 64 0xXX0000
vgcreate newvg /dev/dsk/cXtXdX /dev/dsk/cYtYdY

The XX in the mknod are hex numbers and the combination has to be unique for the system.

lvextend -L new_size_in_MB /dev/newvg/lvolname

This will add a new disk in the volume group and extend an existing volume named lvolname. You must then unmount the filesystem and then extend it using extendfs. If you have the license, you can use the fsadm command to extend the filesystem online.
Is this what you wanted?

vxdestroy_lvmroot

vxdestroy_lvmroot(1M)													     vxdestroy_lvmroot(1M)

NAME

       vxdestroy_lvmroot - remove LVM root disk and associated LVM volume group

SYNOPSIS

       vxdestroy_lvmroot [-v] [-b] lvm_root_disk

DESCRIPTION

       The  vxdestroy_lvmroot  command	tears  down  and removes the LVM volume group associated with the specified physical disk. This is done by
       removing the volumes in the volume group and then removing the volume group.

OPTIONS

       -b	 Invokes the setboot command to change the primary boot disk to the VxVM root disk from which the system was booted (if  the  pri-
		 mary  boot  disk is not already set to this disk).  The alternate boot device remains unchanged.  If the -v option is also speci-
		 fied, the settings of the primary and alternate boot devices are displayed.

       -v	 Outputs verbose messages including a timestamp that indicates major operations being performed.

ARGUMENTS

       lvm_root_disk
	    Specifies the device name of the LVM root disk that is to be destroyed, along with its entire volume group.

EXAMPLES

       This example shows the vxdestroy_lvmroot command invoked in its simpliest form:

       /etc/vx/bin/vxdestroy_lvmroot c5t1d0

       # /etc/vx/bin/vxdestroy_lvmroot -v -b c3t0d0
