The vendor is reporting a non-critical warning because the cooling device temperature is outside of normal operating range.

The cooling device is not operating within the range of lower and upper thresholds which are set by the server vendor.

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

Contact Microsoft Support and provide them with the alert name and details.

To diagnose this issue,

1) Look for other alerts related to cooling devices. A possible cause is a data center air conditioning or other cooling device failure.

2) Microsoft Support will require Windows administrator access to the affected PDW Host node in order to access the vendor’s diagnostic tool to verify the server’s cooling devices and temperature sensors.

To resolve this issue, Microsoft Support will contact the vendor’s hardware support team. Depending on the problem, the vendor might require physical access to the appliance to replace a cooling device.
