           Severity: Major
    Indication Time: Tue Dec 26 01:25:29 2023
           Suppress: false
        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".

               Node: Cluster_01
           Resource: FC_PORT_2
           Severity: Major
    Indication Time: Tue Dec 26 01:22:30 2023
           Suppress: false
        Acknowledge: false
     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.

 

  • storage bridge show -ports command shows bridge port as offline.
