HWNPM4183W number of ranks of the rank statistics from the device agent were unrecognized and were not included in this sample interval.

Explanation

The rank statistics data received from the device agent included data for a number of unknown ranks. This could be due to one of the following conditions:

  • The probe of the subsystem did not complete successfully, and failed to record information for all storage extents of the subsystem.
  • The subsystem configuration was recently changed to add more ranks. These new storage extents have not yet been discovered by IBM Spectrum Control.

Action

Rerun a probe for the subsystem to ensure that any unrecognized ranks are discovered and properly recorded in the IBM Spectrum Control database. If this message persists for subsequent performance data collection intervals, even after successful completion of a probe, contact your IBM service prepresentative.
