Hi,
This is perfectly possible with LVM. First add the HD (aka the HW RAID volume) to the OS. Then do a pvcreate on that disk so that LVM can use it. Then do a vgextend, this adds the disk to the volume group. A vgdisplay should then show that you have again free space in the volume group. Then you can do a lvextend and resize2fs as normal.
