Believe it or not, this is okay and "normal" for a Exx00 disk board. See,
the only thing that the disk board gets from the midplane is electrical
power. Thus the rest of the machine knows something is in that slot, but
cant determine any info on the board, so it's reflected in the prtdiag
output just like you see.
