Well, there seems to be a larger issue here. I can disable the 3 controller cards so the System Board controller is forced to be "Controller #0" (/dev/sda), and then install RHEL successfully.
The problem is when I re-enable the cards, the System Board controller reverts to Controller #2 instead of Controller #0. This also changes the original /dev/sda where Linux is installed... it changes to /dev/sdr. Okay fine. But the operating system cannot be found even though the correct logical drive is set as "Primary Boot" in the Storage Manager. It's like the BIOS is only searching for the OS on /dev/sda. There is no way that I can see to "force" it to boot from /dev/sdr.
Any time you add or remove controllers/drives the enumeration order can and most likely will change, that's just how Linux works. Are you using UEFI or legacy emulation mode?
Something like what I have osted below in the kickstart file should resolve the problem. This is just an example, modify to fit your needs, or use something like the 'list-harddrives' tool in Anaconda to create your own pre script. UEFI is easier to work with in this situation as you don't need to specify the boot drive in RBSU. This example is modified from an example I found on the Internet some time ago.

%include /tmp/part-includeWith Gen10 the embedded µSD controller will take a device name also. Hopefully it enumerates as the last device but that is not always the case. If you are missing a drive letter and can't find an attached device using it, this is likely the cause.
