HWNPM2061W The device does not support performance management for segment pool pool ID. Only incomplete performance data can be collected for device adapter DA ID.

Explanation

The specified segment pool contains multiple ranks, which makes it impossible to accurately manage the performance for those ranks, the arrays associated with those ranks, and the device adapters associated with those arrays.

For DS6000 and DS8000 devices whenever a segment pool contains multiple ranks, any volumes allocated in that segment pool might be spread across those ranks in an unpredictable manner. This makes it impossible to determine the performance impact of the volumes on the individual ranks. To avoid presenting the user with inaccurate or misleading performance data, the Performance Manager does not attempt to compute the performance metrics for the affected arrays and device adapters.
