Mixed RAID configuration
If your system detects mixed RAID configurations with both Windows and Linux RAID disks, then the S150 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 S150 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.
Manage virtual disk properties
The Manage Virtual Disk Properties screen allows you to modify the physical disk write cache policy and view the associated
physical disk and its properties and policies.
In the System Setup Main Menu, click Device Settings > Dell PERC S150 Configuration Utility > Virtual Disk
Management > Manage Virtual Disk Properties
The table explains the Manage Virtual Disk Properties screen details:
Table 11. Virtual Disk Properties
Menu Item Description
Select Virtual Disk Allows you to select the virtual disk from the drop-down menu
Virtual Disk Properties Displays the ID, RAID Level, Status, Capacity, and the Sector Size of the virtual disk
Virtual Disk ID Displays the ID for the virtual disk
RAID Level Displays the RAID level of the virtual disk
Virtual Disk Status Displays the virtual disk status
Virtual Disk Capacity Displays the capacity of the virtual disk
Sector Size Displays the sector size enabled for the virtual disk
Virtual Disk Policies Displays the read and write cache policies of the virtual disk and the write cache policy of
the associated physical disk
Read Cache Policy Displays the read cache policies associated with the virtual disk
Write Cache Policy Displays the write cache policies associated with the virtual disk
Physical Disk Write Cache Displays the status of the physical disk write cache policy
Modify the Physical Disk Write
Cache
Allows you to modify the physical disk write cache policy settings
NOTE: If you have Linux RAID configured on the system, then you cannot modify any settings in this field.
Physical Disk Write Cache Allows you to change the physical disk write cache policy settings. The options are
Default, Enable, and Disable.
NOTE: If you have Linux RAID configured on the system, then you can only view the physical disk write cache setting
Apply Disk Write Cache Settings Allows you to apply the new write cache policy for the Physical disk.
