I should add that mdadm is not present in Ubuntu live images by default - one has to pull it in by issuing "sudo apt[-get] install mdadm". BTW, I don't know if mdadm would detect the RAID controller/disk immediately upon installation, or it would require a reboot. In the latter case you may wish to use a USB key with enough spare room to save the system status and reboot. I'd use UNetBootin to prepare such a USB key.
The main issue here is, a user who doesn't even see a disk, probably wouldn't know to go as far as installing mdadm. IMHO, given the broadening diffusion of NVMe and RAID devices, Debian, Canonical, REDHAT, Fedora etc. might wish to make mdadm part of their live images by default (and eventually strip it from the installed system if it's unnecessary).
