yAllows the allocation of additional physical extents on the physical volume. 

nProhibits the allocation of additional physical extents on the physical volume.  You can, however, access the logical volumes that reside on the physical volume. 

DESCRIPTION

The pvchange command changes the characteristics and state of a physical volume in a volume group by setting the allocation permission for additional physical extents on the physical volume to either allowed or prohibited. 

EXAMPLES

     1.To prohibit the allocation of additional physical extents to physical volume hdisk03, enter:

pvchange  -x n /dev/hdisk03
