finding boot partition on "this" boot drive using fibre channel

I'm researching a boot sequence for a cluster and either the answer is so 
obvious that I'm reading right past it or I can't find the answer.

I have a blade-system cluster of CPUs that share a SAN of fibre channel 
disks.  Once I can get booted to a kernel and load my initrd, I can 
discover everything I need to know to mount the SAN storage for "this" 

The mental roadblock I have is that the BIOS device numbers in the SAN are 
dynamic and can change from boot to boot.  I'd like to install and 
maintain the boot loader and boot partition on only two disks, rather than 
all of them.

I read in an earlier message[1] that GRUB will "guess" the drive number if 
the stage2 loader is on the same drive it boots from.  Will this get me to 
the kernel and initrd that are on the same drive as well?
