1065 One or more fibre channel ports are running at lower than the previously saved speed.

Explanation

The fibre channel ports will normally operate at the highest speed permitted by the fibre-channel switch, but this speed might be reduced if the signal quality on the fibre-channel connection is poor. The fibre-channel switch could have been set to operate at a lower speed by the user, or the quality of the fibre-channel signal has deteriorated.
