IT38509: FLASHSYSTEM WRITTEN CAPACITY METRICS INCORRECTLY SHOWN AS ZERO

APAR status

• Closed as program error.

Error description

• Storage Insights displays the following metrics, incorrectly, as
  zero:
  Written Capacity Limit (GiB),Used Written Capacity
  (GiB),Available Written Capacity (GiB),Used Written Capacity (%)
  
  
  They will be correct, non-zero values immediately after the
  daily full probe is run, but are observed to change to zero
  values after event-driven ?mini probes? are run against the
  device(s).
  The periodic mini probes do not process the received data
  correctly, and as a result the Storage Insights GUI updates
  these values to zero, and they will continue to display as zero
  until the next daily, scheduled full probe is run.
