Unable to configure Linux RAID using UEFI

Configuration Utility

Likely Cause:

Option to select Linux RAID in

Configuring Linux RAID

page will be disabled if RAID is already configured.

Corrective Action:

To resolve this issue:

If applicable, delete the virtual disk created in Windows RAID.

Convert physical disk to Non-RAID disk. See

Converting physical disk to Non-RAID disk.

Convert physical disk to RAID. See

Converting physical disk to RAID capable disk

Configure Linux RAID. See

Configuring Linux RAID

Unable to configure Linux RAID on systems with more

than 10 NVMe PCIe SSDs

Corrective Action:

Ensure that the number of physical disks in a Linux RAID does not exceed 10 NVMe PCIe SSDs.
