If you really want to wipe things clean:

    (1) vgexport /dev/vgname; # avoids collisions w/ stale config info.
    (2) for disk in your disks here; do pvcreate -ff $disk; done;

The export isn't strictly necessar:  rm -rf and a vgscan should do the
same basic thing with a few nastygrams added in.  Personally, I get
enough nastygrams to prefer avoiding a few more :-)
