    >>>>>> POSTPROCESSOR SCM ACTIVITY REPORT <<<<<<
    
    The Postprocessor Storage Class Memory Activity report is
    enhanced to report IBM Virtual Flash Memory activity.
    
    Enhanced report fields for IBM Virtual Flash Memory:
    
    Card ID  The identifier of the flash adapter card. VFM is
             reported if the hardware has configured Virtual
             Flash Memory.
    
    Util(%)  The average utilization of the flash card during the
             interval as reported by the SCM measurement facility.
    
             The average utilization of Virtual Flash Memory is
             reported as the percentage of the time spent on
             System Assist Processors (SAP) for SCM processing
             compared to the total available SAP time in this
             reporting interval.
