Intel® RAID Controller Critical Error: "All of the disks from your previous configuration are gone"

The following critical message appears on every system power on:

Received error message: All of the disks from your previous configuration are gone. If this is an unexpected message, then please power off your system and check your cables to ensure all disks are present. Press any key to continue, or 'C' to load the configuration utility.

This message is to inform the user that the physical or virtual drive configurations have changed from its previous known state (shutdown).
