They should be created in /dev/mpath.  This is done by udev.  Is udev
otherwise working properly.  If you partition the underlying device, do
dm devices get created for the partitions by kpartx?

Also, since the /dev/mapper device nodes exist as soon as the
device is created, and the /dev/mpath symlinks don't get created until
udev gets around to it, you are usually better off simply using the
/dev/mapper names anyways.
