Table 7-3. Warning Messages: Dell Inc. PERC S100 or PERC S300 Adapter BIOS

Warning Message	Corrective Action
WARNING: Found	This warning message appears when at least one virtual disk is
virtual disks	in a Degraded state and Pause if Degraded is set to ON at
that are	the PERC Virtual Disk Management utility.
Degraded	The following message appears after the warning is displayed:
	--- Press <Enter> to continue, or <CTRL><R>
	to enter setup ---
	Press <Enter> to allow the operating system to continue with
	the boot sequence, or press <Ctrl><R> to enter into the
	PERC Virtual Disk Management utility to investigate the cause
	of the Degraded virtual disk.
	To investigate the cause, check for the following:
	• Whether a physical disk in the virtual disk has failed or has
	gone offline. Check the status at the Physical Disks
	field. A Degraded status depends on the RAID level of the
	virtual disk and the number of physical disks that have failed:
	– For a virtual disk at RAID 1 or RAID 5, a single physical disk
	failure causes a Degraded status.
	– For a virtual disk at RAID 10, the failure of a physical disk in
	each of the mirror sets creates a Degraded status for the
	RAID 10. The failure of two physical disks in the same
	mirror set creates a Failed status for the RAID 10.
	• Whether the controller has failed, due to a firmware failure or
	a component failure. A failed controller causes a virtual disk
	not to boot.
	For the virtual disk to recover from Degraded status, the failed
	physical disk must be replaced and the virtual disk must be
	rebuilt, using Dell OpenManage Server Administrator Storage
	Management. When the rebuild operation is completed, the
	virtual disk status changes from Degraded to Ready. For a
	description of the rebuild function, see Storage Management,
	located on the Dell Support website at
	support.dell.com/manuals.
