Event Summary

This message occurs when an error is detected during the periodic health monitoring.

  • System health monitors create alerts for potential problems detected while monitoring the subsystem.
  • The alerts contain information about probable cause along with recommended actions to rectify the problem.
  • The percentage of inbound packet errors of switch interface "Switch Name/Slot: 0 Port: 4 10G - Level" is above the warning threshold.
  • Degradations in the cluster interconnect can result in cluster instability or potentially outages.

HA Group Notification from Node Name (Health Monitor process cshm: SwitchIfInErrorsWarn_Alert[Node Name/Slot: 0 Port: 4 10G - Level]) ERROR

Event Log

[Node Name Name: mgwd: callhome.hm.alert.major:alert]: Call home for Health Monitor process cshm: SwitchIfInErrorsWarn_Alert[Node Name/Slot: 0 Port: 4 10G - Level].

Command Line

system health alert show -node <node name> -monitor cluster-switch -alert-id SwitchIfInErrorsWarn_Alert

                      Node: Netapp-a
                   Monitor: cluster-switch
            Class of Alert: SwitchIfInErrorsWarn_Alert
         Severity of Alert: Major
            Probable Cause: Threshold_crossed
Probable Cause Description: The percentage of inbound packet errors of switch interface "$(cluster_switch_analytics.unique-name)" is above the warning threshold.
           Possible Effect: Communication between nodes in the cluster might be degraded.
        Corrective Actions: 1) Migrate any cluster LIF that uses this connection to another port connected to a cluster switch.
For example, if cluster LIF "clus1" is on port e0a and the other LIF is on e0b,
run the following command to move "clus1" to e0b:
"network interface migrate -vserver vs1 -lif clus1 -sourcenode node1 -destnode node1 -dest-port e0b"
2) Replace the network cable with a known-good cable.
If errors are corrected, stop. No further action is required.
Otherwise, continue to Step 3.
3) Move the network cable to another port on the node (if available).
Migrate the cluster LIF to the new port.
If errors are corrected, contact technical support to troubleshoot the original node port.
Otherwise, continue to Step 4.
4) Move the network cable to another available cluster switch port.
Migrate the cluster LIF back to the original port.
If errors are corrected, contact technical support to troubleshoot the original switch port.
If errors persist, contact technical support for further assistance.

Resolution

  1. Perform link troubleshooting on the port reporting SwitchIfInErrorsWarn_Alert:
  2. Attempt Reseat of cable and/or SFPs.
  3. Confirm cable and/or SFP is a supported part.
  4. Check for any patch panel between controller and switch that could be present, bypass it if possible.
    1. If the issue persists, replace SFPs and/or cable.
    2. If the issue persists, swap the connection with a good known port on the switch end and check if the alerts are reported.
