[linux-lvm] how to remove physical volume

[Sambit Nanda]

 pvscan
pvscan -- reading all physical volumes (this may take
a while...)
pvscan -- inactive PV "/dev/cciss/c0d1" is in no VG 
[67.83 GB]
pvscan -- total: 1 [67.83 GB] / in use: 0 [0] / in no
VG: 1 [67.83 GB]

my pvsacn give this output. 
  now i need to remove "/dev/cciss/c0d1" from my
pvscan so i will able to create the partion once again
using fdisk 

what command should i use to remove this ?
or can i use fdisk without remove this, is it going to
make any impact ??

Thanks,
