Hi,

try to initialize the disk first with pvcreate.

If you are sure that it isn't used, try to force initialization with -f flag.

Hai,

First u can create PV
#pvcreate -F /dev/rdsk/pvname
#vgextend vgname /dev/dsk/pvname

You can try with this.

Chandra - the parameter is -f not -F.

SKR - did you pvcreate your new LUN?
double check that you did it in new LUN.
