HWNPM4191W number of modules out of total number of modules module statistics could not be retrieved from the device agent due to errors, and were not included in this data collection interval.
Explanation
Each interface module in an XIV device is responsible for tracking performance statistics of the I/O flowing through it. In this case, one or more of the interface modules did not return its statistics data to IBM Spectrum Control. This is usually caused by the particular modules being inoperative.
Action
Check the health status of your XIV interface modules, and correct any errors. If this message persists for subsequent performance data collection intervals, even if all XIV interface modules are fully operational, contact your IBM service representative.
