For PATA the requirements I'm aware of are - Interface for user to say "am about to swap" - Interface for user to say "have swapped" - Must quiesce both master and slave before swap (or one per cable) - Must reset to PIO_SLOW and then recompute modes for both devices becuse it is possible that changing one changes the other timings - The above is true for *unplug* too. A straight unplug may speed up the other drive! - Post hotswap need to reconfigure both drives as if from scratch - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
