can't you just use raidtools or mdadm?

You can use hdparm to quiesce the bus. Your version of hdparm support
hotswap, but no guarentees if your kernel does.

Even if it does work for your kernel, I have to advise against your
approach, because hotswap != removable storage. If you have wiggle
room in the colo space, give firewire a fair chance.

I believe this only tickles the md driver and not the bus.
