When the router is operational and the hard disk is removed from the boot list, a minor
yellow alarm is generated. When the router is rebooted and the hard disk is still removed
from the boot list, a red major alarm is generated.
The command output displays a major alarm indicating what media is missing from the
boot list and the time and date when the event occurred.
