HWNPM2124W Performance data continuity is broken. The device was possibly reset or rebooted. record count performance data records were discarded.
Explanation
The message indicates that invalid performance information was received from the device.
In general, performance information is represented as a set of ever-increasing counters, and actual statistics are computed by taking the difference between two consecutive sets of such counters.
However, if a counter appears to decrease rather than increase between consecutive sets, the information is unusable and is discarded.
Counters can be expected to decrease if they are reset to zeros, which might happen normally when a device is reset or rebooted. For example, when new firmware is loaded, or in some cases when a device agent (such as an SMI-S provider) is reset or rebooted. In those situations, this warning message can be safely ignored.
If this warning is displayed when no reset or restart happened, the device or device agent might be generating incorrect performance statistics. You might have to contact your device vendor for further instructions.
Action
Determine whether the device or device agent was reset or rebooted.
Those situations include loading of new firmware, or fail-over and fail-back scenarios for Enterprise Storage Server, DS6000, and DS8000 storage subsystems.
In any of these cases, the reset of performance counters is expected behavior, and this warning message can be safely ignored. If it is not one of these cases, the device might be generating incorrect performance data, which might or might not lead to inaccurate performance reports.
Contact your device vendor for further instructions in those cases.
