Can you do pasu <node> show BootOrder You could, if you'd like, change the boot order to 'Hard disk 0' with asu/pasu and it should work (centos 7 will work that way, centos 6 will not).
I may also like to see asu show all if you can't find hard disk at all.

There is no special partitioning and only one "visible" hard drive (there are two physical drives setup in a hardware mirror). I'm relatively new to UEFI systems. Perhaps if I understand it better I can troubleshoot it better. Where can I learn more about the UEFI install procedure that you mentioned above?

For reference, on install UEFI compatible systems look at the partition id they write their boot loader to. They take the partition uuid and tell UEFI firmware 'hey, next time boot to this file on the partition with this UUID'. If it for some reason selected a storage device that is *not* visible from UEFI, this behavior would be seen (It's looking for a UUID that doesn't exist). Is there a custom partition plan? Are there multiple disks? Some versions of CentOS will struggle if '/boot' and '/boot/efi' get split up, for example.

Upon reboot, the machine fails to boot because it can't find a valid OS. Using rcons to get to machine console, we find a new boot option named 'CentOS' and it is first in the boot priority list. Does anyone know where this comes from? Why it's there? How to fix it or prevent it from getting set in the first place? Even a gentle shove in the right direction to troubleshoot this would be greatly appreciated. Cheers, --Andy
