Okay, I will try and do this.

Okay, do you mean to mount one of the RAID1 members to /boot directly 
and run grub2-install, correct?

Or copy the contents of /boot, format an individual partition, mount it 
on /boot, copy the data back, and run grub2-install?

The BIOS does show all four disks in the "Boot" menu as being an option. 
If I remove the two new disks, it does then boot properly without doing 
anything else.

No, I don't see any reference to EDD in /sys or in the boot logs.

Thanks,
