I have add sda and sdb for our linux and multipath them(because they are
point to same LUN).
Then I logoff this linux guest and re-logon, everything is fine and we can
access new LUN disk space.
Then I use same method to add sdc and sdd for this linux and multipath them
(they are same LUN).
However, linux was booted abnormally, the whole startup message is
following. Any one know what cause it?
