How do you attach an image? I have some iLO screenshots that show the issue. I haven't had any issues with sd or usb showing up on disk enumeration.
Basically, sda is correctly pointing to 1:1:0:0 during anaconda. Which is the first logicaldrive. sdb-j all point to their repsective arrays. Then anaconda runs ssascripting to load the raid config, and sda points to the logicaldrive 3 typically when the raid config is complete.
Thanks
