Acknowledge: false
Probable Cause: FC initiator adapter 2d is at fault.
Possible Effect: Resiliency of backend storage is compromised.
Corrective Actions: 1. Ensure that the FC initiator link has not been tampered with.
2. Verify the operational status of the FC initiator
adapter by using the command "system node run -node
local -command storage show adapter".

Probable Cause: The port "FC_PORT_2" on the bridge
"ATTO_X.X.X.X" is offline.
Possible Effect: Failure of the port "FC_PORT_2" in the bridge
"ATTO_X.X.X.X" might cause loss of redundancy.
Corrective Actions: 1) Check the operational status of the ports on the bridge by using the command "storage bridge show -ports".
2) Verify logical and physical connectivity to the port.
