here is our multipath.conf
cat /etc/multipath.conf

---------------------------------------------------------
i've seen inside multipath dry run that local, single path devices are listed as mpatha and mpathb,
i think modifying the second row into blacklist section as follows may solve this discrepancy
devnode "^(td|hd|sd)[a-z]"
waiting your ideas about our config!!
