— Address ID errors—Received frames had unavailable or invalid Fibre

Channel destination addresses, or invalid Fibre Channel source addresses.

This typically indicates the destination device is unavailable.

— Frames too short—Received frames were less than the Fibre Channel

minimum size, indicating the frame arrived at the director port corrupted.

Frame corruption may be caused by device disconnection, an optical

transceiver failure at the device, a bad fiber-optic cable, or a poor cable

connection.
