Health Monitor process nchm: StorageFCAdapterFault_Alert - AutoSupport message

Applies to

• MetroCluster FC
• ONTAP 9
• StorageFCAdapterFault_Alert

Event Summary

StorageFCAdapterFault alerts are generated on MetroCluster Fibre Channel systems when ONTAP health monitor detects that an FC initiator port is down.

Validate

• Check the output of system health alert show to see the current reporting errors:

Cluster01::> system health alert show
               Node: NodeA-01
           Resource: 2b
           Severity: Major
    Indication Time: Thu Aug 05 00:06:31
           Suppress: false
        Acknowledge: false
     Probable Cause: FC initiator adapter 2b 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".

 

• Check the current status of the reporting adapter: system node run -node <node_name> -command storage show adapter <adapter>

Cluster01::> system node run -node NodeA-01 -command storage show adapter 2b
