Offline or missing virtual drives with preserved cache error message

Error Message:	There are offline or missing virtual drives with preserved
	cache. Please check the cables and ensure that all drives are
	present. Press any key to enter the configuration utility.
Probable	The controller preserves the dirty cache from a virtual disk if the disk becomes
Cause:	offline or is deleted because of missing physical disks. This preserved dirty cache is
	called pinned cache, and is preserved until you import the virtual disk, or discard
	the cache.
Corrective	Use the <Ctrl> <R> utility to import the virtual disk or discard the preserved cache.
Action:	For the steps used to manage preserved cache, see Managing The Preserved
	Cache .

Virtual disks offline error message

Error Message:	x Virtual Disk(s) Degraded, where x is the number of virtual
	disks degraded.
Probable	This message is displayed when the BIOS detects virtual disks in a degraded state.
Cause:
Corrective	Take corrective action(s) to make the virtual disks optimal. The BIOS does not take
Action:	any action.

Virtual disks degraded error message

Error Message:	x Virtual Disk(s) Degraded, where x is the number of virtual
	disks degraded.
Probable	This message is displayed when the BIOS detects virtual disks in a degraded state.
Cause:
Corrective	To make the virtual disks optimal, take one the following corrective actions:
Action:	• Ensure all disks in the Virtual Disk are present and online.

	• Replace any failed disks that may be in the array.
	• Correct a hot spare disk, and rebuild the array.
	The BIOS does not take any action.

Virtual disks partially degraded error message

Error Message:	x Virtual Disk(s) Partially Degraded, where x is the number of
	virtual disks partially degraded.
Probable	This message is displayed when the BIOS detects a single disk failure in a RAID 6 or
Cause:	RAID 60 configuration.
Corrective	You must check why the member disk is not present to correct the problem. The
Action:	BIOS does not take any action.
