Suppose, we unplug and then re-plug a disk, will VDSM expect the disk be in the same device path as before? More generic, will the unplugging and plugging keep the PCI device path as the same as before?
No guarantee for that. For example, suppose you unplug a disk, plug another disk then re-plug the first one. Unplug is just like removing a physical disk from your machine, the disk does not have any property stating what PCI address it had.
It would be nice though if the address were kept and when plugging, if the address is not taken then use the same one and if taken then remove address and let the system choose where to place it...
ack. Basically when you unplug the disk the management clears the device address and the device is left with no address. next time you plug the device and run the VM the management will learn the new address and persist it. Livnat

The feature is simple and design is short
