Explanation: SUMMARY is an optional parameter
requesting that DFSMShsm print a summary of statistics for the days
you specified with the FROMDATE and TODATE parameters.
Defaults: None.
Note: - You specify REPORT DAILY FUNCTION SUMMARY to get the summary totals
for the daily statistics for all functions. You specify REPORT VOLUME
FUNCTION SUMMARY to get the summary totals for the volume statistics
for all volumes and for all functions. You specify the VOLUMES parameter
with a volume serial number to get summary statistics for only one
volume. If you request a summary of specified functions, the summary
contains the statistics totals for only the specified functions.
- When you specify SUMMARY, you get only the summary report. If
you do not specify SUMMARY, you get the statistics report you requested,
and a summary at the end of the report if DFSMShsm reported the statistics
for more than one day.
