HWNPM4066W count of null operational status null Port Operational Status value(s) for performance data collected from the device was/were substituted by default value(s).
Explanation
The switch device did not report the required SMI-S provider OperationalStatus property for the reported number of statistics instances reported. These were substituted by a default value of port operational status ('unknown'). This can be caused either because an assembled FCPort CIMInstance was used by Fabric Data collection code, or by an error in the provider for the device.
Action
If this warning occurred when collecting performance statistics for all the ports of a switch, contact your IBM support representative, and switch vendor.
