[Veritas-vx] Extended vxdisks after growing underlaying physical disks

I am running Solaris 8 with VxVM 3.2 or 3.5. I have a HW RAID box
(HDS, EMC, or IBM) where I have the simple Vx disks (slice s3 with
private region and slice s4 with data).
If I extend the physical disks in the HW raid box (growing it via
concatenation or extending the strip, it is not relevant for this
dicsussion), it is possible to "grow"the Vx disks? It looks
technically feasible, since the size (len) is saved in the private
region and the public region is the "last"part on the disks...
Of course, we need to relabel the disks with the new size, but that it
is easy with "format -x"and äuto".
I have looked through the man pages for the VxVM 3.5 but found no way
on how to signal to VxVM to ëxtend"the VxVM disks to the new size. I
could always try to set the "new"size in the private region, but it
feels like a real hack.
Notice that it is possible under W2K to grows the VxVM disk when
the underlaying physical disk have been extended.
thanks in advance,
PS1. For the moment I am missing a testing environment to verify if this
is at all possible.
PS2. Normally, I would just make another LUN available from the HW RAID
box, then do a devfsadm assuming sd.conf is already populated.
