It works here :(
Try to extract the live blacklist with :

# multipathd/multipathd -k"show conf"
...
blacklist {
        devnode ^(sda)[0-9]*
        devnode ^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*
        devnode ^hd[a-z]
        devnode ^cciss!c[0-9]d[0-9]*
        wwid 26353900f02796769
        device {
                vendor IET
                product A.*A
        }
        device {
                vendor DGC
                product LUNZ
        }
}
...
