When I hot-remove a SATA HD in AHCI mode and then hot-plug the drive back in again, the /dev/sdX number changes to the next available number. Is this going to be a problem when using a RAID array that includes that drive?
Well, it's certainly something you have to deal with. You have to tell the RAID driver you added a component to the system. Ideally mdadm or udev should take care of that, but I'm not sure it's all there yet.
In any case, it's a new device so, while inconvenient for some scenarios, I think it is best to represent a new device with a new device node. Various entities are still probably holding references to the old device, and you don't want the system to think that you plugged in the _same_ device again.
