A server has lost communication to its drives located on a fiber channel SAN. An administrator notices that the indicator lights on both the HBA and the SAN switch are not lit. Which of the following

If the Host Bus Adapter (HBA) itself has failed, it cannot communicate with the SAN, and its indicator lights would typically be off, preventing any link activity with the SAN switch.

A failed port on the SAN switch would prevent communication over that specific port, resulting in no link light activity on both the switch port and the connected HBA.

A faulty or disconnected fiber cable between the HBA and the SAN switch would break the physical link, causing indicator lights on both ends (HBA and switch port) to be unlit.

A faulty driver might prevent the operating system from recognizing or utilizing the HBA, but the physical link lights on the HBA and SAN switch would still typically be lit if the underlying hardware and cabling were functional.

Failed hard drives in the SAN storage would affect data access from the storage array but would not typically cause the HBA and SAN switch link lights to be unlit, as the SAN fabric itself would still be operational.

A faulty configuration would generally still allow the physical link to establish and lights to illuminate, but prevent logical communication or data access, rather than causing physical link lights to be off.
