hi narsimha,
If u want to completely remove ur PV (i.e. if u want to lose ur data) then
there is a very simple way to get rid of this problem. Just do following....
dd of=/dev/hda3                  ......hda3 becuse ur PV resides on that
<enter approx 50 chars>
<press cntrl+d>

Of course it not the recommend solution, but it will solve ur problem :-)
Actually ur VGDA data on the disk may be corrupted, that's why u r getting
this error message.
When u create a PV/VG, some data is written on the disk (on some initial
disk blocks). So if u erase that by doing 'dd', then u can create fresh
PV/VG using that disk.
