I just experienced that.

I had to reboot the machine to "see" the expanded LUN.
I used fdisk to make a partition out of the LUN expansion, but I had to reboot again before I could do anything further.
After the second reboot, I was able to make a PV out of the new partition, roll it into the existing VG and then expand the two test LV's I had previously created to utilize the new elbow room.

This is on a RHEL 5.7 system.

Is there a way to do this without the rebooting ?
