So, let's imagine following situation:

We get SCSI BUS with removable da device.
device detected as da0 and not mounted.
Device disconnected from SCSI bus.
And finally, another device with different geometry connected with same
SCIS ID.

Please describe how to suppose detect geometry change in this case ?
