That's never how it works. multipath has no kernel module loading ability. Would make a nice feature though. I admit that discovering "which dh is the necessary one" is a bit arcane and not well documented anywhere.
The best practice here is to load the necessary device handler into your initrd so it's attached at the same time the SD devices are initially discovered. You still need to have this module loaded to provision additional luns at runtime and not have their performance plummet. Also, I discovered a typo in the multipath documentation. https://bugs.launchpad.net/serverguide/+bug/1057071 Had that worked to begin with, you would have never encountered this issue in the first place. Closing this issue as "Invalid" as it's not a bug.
