How are you setting up the md device? My issues is how to reclaim a failed path on the md device? So I set mine up like this: mdadm --create -f -l mp -n 1 x 1 /dev/md0 /dev/sdx /dev/sdy (assuming x and y are the two paths into the one lun). On testing fail over, it takes about 12s to fail over. Checking the md device shows this, however, how does one re-enable the failed lun?
