Volume Space menu
The Volume Space menu options provide historical information about how the volumes in your enterprise are being used and who is using them.
You can use this information to make decisions about adding additional volumes or reallocating volumes. Using the TIME command, you can view trends in volume usage over specified time periods.
With all Volume Space views, you can use the TIME command to set date and time ranges for the reporting period.
MainView SRM retrieves start and end dates and times from the parameters in the MainView TIME command. If you have not set the TIME command, the default time range is 7 days (168 hours) before the current date and time to the current date and time.
The following table summarizes each volume space option and its corresponding SETSRM keywords, action line commands, and EZCmd menus.
