Not an issue. All our machines are set up like so.
alias lilo="lilo -C lilo-a.conf; lilo -C lilo-b.conf"
where
lilo-a.conf:
boot=/dev/hda
root=/dev/md3
lilo-b.conf:
boot=/dev/hdc
root=/dev/md3
That way if disk 0 dies you just pull it out (We use IDE drive caddies)
and boot away. Or if you have a decent enough BIOS just tell it to boot
off the other drive.

Nope comes up fine with a broken mirror and after you give it a new
drive will rebuild in the background.
