Upgrade key not present?

Solution 1:

This is potentially a little weird; but consider powering off and removing/reseating the hardware key for the RAID. I don't specifically know for your model; but many Dell's have a tiny little daughter card for this purpose.

Solution 2:

Dell PERC daughtercards have a tendency to wiggle their way slightly out of their socket, usually as a result of careful handling by the shipping company. ;-)

Many on-boot RAID controller problems on Dells can be resolved by simply removing the daughtercard and then reseating it. Note the blue circles on the card, those are the places where you should push down.

You should also unplug and replug in the SAS/SATA cables as well. Same issue, delicate handling by a shipping company can cause them to be loose.
