So just to clarify, you are actually entering the proper RAID interface for accessing your drives, right? 

A new dell with an add on raid card will, in some cases, have two raid interfaces during boot up. One for stock internal RAID, and one for the LSI RAID. If you have the upgraded raid card, you maybe be entering the wrong interface for accessing the raid. Also, if this is new, you could easily get a chat going with Dell to help break the RAID like the previous answer suggested. 

Either way the RAID card driver is not supported with the Linux distro you've chosen and would need to be added. It's not hard, just takes some googling and use of centos.org howtos

So, question is, when in the RAID interface that you actually see, you cannot destroy what is there? If that's the case I believe the raid interface is reading "RAID" or member from the beginning of the hard drives and they will be unusable until you break the raid in the actual interface.
