Some users familier with
|
||||||
|
.Xr umass 4
|
||||||
|
might wander why the device is not detached at the CAM layer when the device
|
||||||
|
is unplugged. It's detached only if the device has not been plugged again
|
||||||
|
during several bus resets. This is for preventing to detach an active filesystem
|
||||||
|
even when the device cannot be probe correctly for some reason after a bus reset
|
||||||
|
or when the device is temporary disconnected because the user changes the bus
|
||||||
|
topology. If you want to force to detach the device, run 'fwcontrol -r'
|
||||||
|
several times.
