parted and formatting partitions

[WarNinja]

Hey guys,
I am running Redhta 5.4 Ent with 32GB of Mem and 6TB of hard drive space.
running on a Dell 2950

I had to break up the har drive into less then 2TB partitions.
I used the Dell raid utility to create the paritions

I created 1 parititon to be 800GB Redhat is installed on that parititon.
I plan to Run Oracle on this server.

So my question is how do I get the OS to recognize the other 2 x 2TB partitions?
if I do a df -h all I see is the parititon where RedHat has been installed.

I am having a heck of a time just formatting it Ext3 on /dev/sdb

Any help would be greatly appreciated.

My partition layout is below

parted) print all
