In the bios from my machines (Supermicro, Dell) I can select only one drive to boot. Wenn the drive fails, no other disk is tried. I can go into the bios and change the drive when it fails, or I can exchange the disks. But I would like it, when the machine would simple boot even when the first disk is corrupt.
