Mixed RAID configuration
If your system detects mixed RAID configurations with both Windows and Linux RAID disks, then the S140 UEFI configuration
utility displays the mixed configuration 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 configuration.
b. Select the physical disks with Linux RAID configuration 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 configurations from the system.
2. To convert the Windows RAID disks:
a. In the WARNING: MIXED CONFIGURATION screen, select Linux RAID configuration.
b. Select the physical disks with Windows RAID configuration 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 configurations from the
system.
NOTE:
The S140 controller does not support a mixed RAID configuration. If the mixed RAID configuration 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.
