Are you doing this in the correct order?  Shouldn't you _de_activate the 
VG _before_ removing the disks?  And besides, shouldn't you remove the 
offending disks from the VG _before_ deactivating and then removing the 
disks physically?  Or at least something equivalent.

1.  vgreduce vg00 <offending disks>
2.  vgchange -a n vg00
3.  disconnect the disks
4.  vgchange -a y vg00
