Dell PowerEdge - Mixed RAID Configuration Handling; Managing Virtual Disk Properties

Mixed RAID conguration
If your system detects mixed RAID congurations with both Windows and Linux RAID disks, then the S140 UEFI conguration utility
displays the mixed conguration screen where you are encouraged to perform the following tasks:
1 To convert the Linux RAID disks:
a In the WARNING: MIXED CONFIGURATION screen, select Windows RAID conguration.
b Select the physical disks with Linux RAID conguration listed, and click the link CONVERT TO NON-RAID. If you do not want to
convert the disks to non-RAID, remove the physical disks with Linux RAID congurations from the system.
2 To convert the Windows RAID disks:
a In the WARNING: MIXED CONFIGURATION screen, select Linux RAID conguration.
b Select the physical disks with Windows RAID conguration listed, and click the link CONVERT TO NON-RAID. If you do not
want to convert the disks to non-RAID, remove the physical disks with Windows RAID congurations from the system.
NOTE: The S140 controller does not support a mixed RAID conguration. If the mixed RAID conguration with both Windows and
Linux RAID disks is detected, then you cannot perform any further tasks until you clear the physical disks or convert the physical
disks.
