That makes sense.  Thanks for the confirmation.

Both, I guess.  I'm following the Red Hat how-to and I'm getting that
error instead of getting a successful output.  If there's an answer for
why I'm getting the error, or an answer for how to fix my multipathd,
I'm open to either one at this point.  :)

I attempted to put sda in my blacklist (per the Red Hat instructions)
but still received the same error message about sda (the local disk).

Thanks,
