You will first have to add the new disk into the volume group before you can extend the volume.
vgextend is what your looking for

Try this : http://tldp.org/HOWTO/LVM-HOWTO/

If your disk have free space, first create a partition of that free space and after that include that partition into volume group. After creating partition using fdisk use vgextend command to include that partition into Volume Group. Now try lvextend.

Thanks
