ABSTRACT:
A mechanism is provided for detecting new devices added to a Fiber Channel adapter. When a device is added to a connector, the mechanism generates a device detect signal for that port. The Fiber controller receives device detect signals for the existing ports and generates port select signals to configure the port bypass. The controller may then simply poll the device detect signals in an internal register to automatically detect a new device being added or a device being removed without breaking the loop and without a high software overhead.
