The recommendations I've seen are to avoid using /dev/sdx for exactly this reason. Instead you can use either file system labels or otherwise persistent names generated by udev based on parameters that won't change.

It seems that the device name (/dev/sd?) that is assigned to each virtual drive is somewhat arbitrary. It was in order of creation, but after a reboot, it changed to order of enclosure/drive. This, as you can imangine, is not a good thing. What is the best way of locking a device name to a virtual disk? udev? Thanks!
