I have a Dell 1500 sc that I am using for a file server. It came configured with a Dell Perc 3/sc raid controller and 2 18 gig hard drives set as raid 1. I needed more space so I installed 2 more 16 gig scsi hard drives. My question is can I set these drives up as another pair raid 1 drives. The raid controller sees them but I'm not sure exactly what to do in the raid setup. They are formatted but Server 2000 doesn't see them. Are there 2 channels on the controller for this purpose?
