Discs not showing for install

Ok so I am ready to take the leap of faith here and come over to RHEL but.. Now I am getting to the setup screen 2nd page where it is telling me It can only see 1 drive and that drive is the USB with the ISO on it. The other 6 drives do not appear at all in the list of drives.

Here is what I have

Dell power edge server
Raid Perc 6/i
6 2TB drives in the system
2 NICs 1 to the internet and 1 LOCAL ONLY for SPEED direct to computer
for transferring

Raid is set up as RAID-0 Currently in HARDWARE RAID on PERC 6/i

But not seeing ANY of the drives to install to...
They are all NEWLY initialized drives with NO partitions on them at all.

Forgive me but I am SUPER new to this and will require step by step directions on how to fix this and get the software installed.. Thank you
