Yes, only Active side will have the path records. But port may fail on 
the Passive side too.
When a port is failed on the Passive node, active node also need to 
change the QP state to migrated.
Only Active node can reload the alternate path. So if the path comes 
back on the Passive node, it has to send event notification to the 
active to reload the alternate path. With my ib_sa_serv_notice_hdlr() 
and your CM changes I have tested all possible combinations. It was 
working fine.
