Volume History Report
The Volume History Report displays summary information for volume performance data when one of the three summary report option keywords, DAY, WEEK, or MONTH, is used. If none of the three summary report option keywords is used, the Volume History Report displays snapshot data for the volume that is specified by the VOLSER report option keyword.
Note
The PERF_VOL report name verb can create two different reports: Volume History Report and Volume History Snapshot Report. The Volume History Report is generated when the VOLSER report option keyword is used with a complete volume serial number, while the Volume History Snapshot Report is generated when the SNAPSHOT report option keyword is used.
