[rhn-users] opposite command of pvcreate ???

[Sambit Nanda]

Is there any command exactly oppose to pvcreate ?

when i ran thoi command 
pvcreate /dev/cciss/c0d1p[5-13]

i got this error  :  pvcreate -- can't open physical
volume "/dev/cciss/c0d1p3" to get its size

though i have not mentioed the device c0d1p3

then i noticed from pvscan 

pvscan -- inactive PV "/dev/cciss/c0d1p1"  is in no VG
 [1 KB]
pvscan -- inactive PV "/dev/cciss/c0d1p5"  is in no VG
 [9.32 GB]
pvscan -- inactive PV "/dev/cciss/c0d1p6"  is in no VG
 [9.32 GB]
pvscan -- inactive PV "/dev/cciss/c0d1p7"  is in no VG
 [4.66 GB]
.....
....
..


the c0d1p1 is acctually my   Extended  partion

but my pvscan also show the same device
pvscan -- inactive PV "/dev/cciss/c0d1p1"  is in no VG
 [1 KB]

i do not what is wrong here, so i like to remove this
enrty from my pvscan 

i tried with pvmove and got error 
ERROR: can't move physical extents: volume 

please guide me how i will able to move the enrty ? 

or what is the exact command to remove or delete all
physical volume. 
If i want to remove all physical volume i created 

Thansk
