I agree with what John said about their command line interface MegaCli.
One thing I have noticed about LSI MegaRaids is: if you hot replace bad
drive with good one of the same size or larger (which doesn't have on it
traces of being configured in any raid, not necessarily LSI), then the
drive is accepted as replacement member into the same volume group, and
array gets rebuilt in background automagically. You may want to check
first if it is on its way rebuilding already.
