Smart Array 410i logical drive extended but size not updated in RedHat

I've added 2 disks to the Smart Array 410i and extended the logical drive, but I am unable to rescan the

cciss driver to update the drive size in the OS.  I've tried a reboot and that doesn't work either.


Please help!

The 1.23TB PV needs to show the new  2TB size.

It's been some time since I've done this, but if I recall you need to create a partition on the free space, then add it into LVM. A quick search I turned up this which oretty much echo's what I recall.
