IT38743: STORAGE INSIGHTS DASHBOARD SHOWS PHYSICAL DATA RATE (MIB/S) VALUES THAT ARE INCORRECT (TOO HIGH)

APAR status

• Closed as program error.

Error description

• Data Rate graph is not accurate.
  It shows wrong value e.g. 15 billion MiB/s.
  Data Rate values for subsystem can show big values, billions
  MiB/s.
  This can be seen at the subsystem level and also at volume,
  disks or node level. Looking at the component level (volume,
  disk) the value just before the big value is missing.
  This is because that is not returned by the subsystem.
  The big value is a calculation error in SI caused by the fact
  that the previous value is missing.
  The other values for the same metrics are correct.
