In older versions sdb would become sda, but I don't have enough time on the 6 series to know for sure... Maybe I will fire up a virtual machine with a couple emulated sata drives and see....
Sda/sdb are the kernel's conventions. What matters is what bios sees. And that may be different depending not only on the hardware but also the failure mode - sometimes a drive will fail but not really disappear from detection and it is hard to emulate that. Also, back in ATA days it was pretty common for a failed drive to lock both channels on the controller.
As long as you have physical access to the box you can fix it fairly quickly by booting a rescue iso and re-installing grub, even if you have to try a couple of times to get it right.
