Not likely, but it depends on your hardware setup -- it depends on what
exactly is on those disks.
If you're using fakeraid, then I'd reject sd.* and accept .* (which
would include the /dev/mapper/XXXX fakeraid DM device).
If you're using multipath, then I don't know -- follow the multipath docs.
If you're using LVM on md-raid, then it should be working properly by
default without this change (though md_component_detection must be set
to 1, so you may want to double-check that setting if your system is set
up like this).
