Cent OS and Raid Drives on 4600

[Trey Copeland]

Hello. This is my first post to the list.

I have a Dell Poweredge 4600 running Cent OS with 3 raid drives and 4 
power supplies in it. This is my first time to play with a machine like 
this. I managed to setup DNS/web/mail on it as well. It looks like it's 
only recognizing one of the drives though when booted up in linux. When 
the machine is rebooting, it looks as if it finds all three drives 
though. Any suggestions as I'm clueless and not sure what to do?
