firstly... it is really hard to help you, because you don't post the
actual output of the tools/commands that you've used, or of things
like cat /proc/scsi/scsi.
eg, it's still not clear whether linux sees megaraid devices as SCSI
disks or not. whether the extra space was added to an existing disk or
whether it has appeared as a new disk.

(unless you can unmount everything and the megaraid driver is a
module. what does lsmod say?)

you probably need the reboot to see the extra space.
however, why do you want to grow an LVM partition???? even if you
could, there is no way to tell LVM that PV has increased in size.
Instead... make a new LVM PV partition out of the extra space. (ie do
not repartition - just add a new one on the extra space). Then
pvcreate and vgextend to add this new PV to your VG.
