Increase size of LUN

SAN: Calriion CX3-10C

How can I increase size of LUN (50GB) attached to Linux Red Hat host (RHEL 5.2) 64bit by adding new created LUN (200GB)?

What steps do we need to take to get the Linux host to see the new space? I am going to present a new LUN from EMC array to the Linux system.

The existing system partion it looks:

# fdisk -l
