Check multipath.conf.annotated in the source. This will retry n times
before failing.
no_path_retry {n}
I have repeatable issues with setting this higher than about 3-5
however, where IO queues (more like blocks) forever, even after failing
the path back... requiring a reboot, and resulting in data corruption. YMMV.
