Summary

The network adapter is reporting a critical failure. This could cause a cluster failover event.

Causes

This occurs when the network adapter is in one of the following states:

  • Offline (vendor status: 8)

  • Powered off (vendor status: 7)

  • Off duty (vendor status: 9)

For more details, view the component's adapter_device_status property in the PDW Admin Console or query the sys.dm_pdw_component_health_status DMV.

Resolutions

To diagnose this issue:

1) Use the sys.dm_pdw_errors and sys.dm_pdw_os_event_logs DMVs to check for relevant failures.

2) Verify if this caused a port failure. To do this, use a Windows administrator account to login to the Management node. Open a command window and ping the IP address for the affected network adapter.

3) If you cannot ping the network adapter, the port may have failed. Access the physical appliance to check the cable connections. Check the network switch logs for this port to determine if the switch has issues.

To resolve this issue, contact Microsoft support and provide them with the information you have gathered. Microsoft Support will help you to understand the failure and help you to bring the network adapter back online or into a healthy state.
