7.2. RAID or Other Nonstandard Configurations

Certain RAID systems or other nonstandard configurations may be unreadable to the installation program and the aforementioned prompt may appear. The installation program responds to the physical disk structures it is able to detect.

If you have a nonstandard disk configuration that can be detached during installation and detected and configured afterward, power off the system, detach it, and restart the installation.
