181The
182.Nm
183driver depends on the underlying hardware drivers to do the right thing in case
184of a path failure.
185If for example a hardware driver continues to retry forever,
186.Nm
187is not able to re-initiate the I/O to an alternative physical path.
188.Pp
189You have to be very sure to provide a unique label for each of the
190.Nm
191devices.
192Safety belts are not provided.
193For FibreChannel devices it is suggested to use the Port WWN of the device.
194The World Wide Name is guaranteed to be worldwide unique per the
195FibreChannel standard.
