The network adapter connection is in a non-critical state. The port is probably operational, but can cause performance to degrade.

This can be caused because of one of the following reasons:

• The network is in a connecting state (vendor status: 1).

• The network is in a disconnecting state (vendor status: 3).

• Network authentication is in process (vendor status: 8).

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

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 Host 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.
