HWNPM4187W The device does not support performance management for pool pool ID because it contains Space Efficient Volumes. Only incomplete performance data can be collected for array array ID.

Explanation

The specified pool contains space efficient volumes, 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 DS8000 devices whenever a pool consisting of multiple ranks contains space efficient volumes that are not yet fully allocated, the performance impact of those volumes on their associated ranks cannot be measured. As a result, to avoid presenting the user with potentially inaccurate or misleading performance data, the Performance Manager does not attempt to compute the performance metrics for the affected arrays and device adapters
