Dell PowerProtect DD Management Center (DDMC) 7.9 Installation and Administration Guide

Managing measurement schedules for physical capacity

You can management measurement schedules for physical capacity using the Manage Measurement Schedules dialog.

About this task

NOTE You cannot directly add up Physical Capacity Measurements because a certain amount of sharing occurs between MTrees, so any totals generated can often be misleading. In the following picture, the Tenant Unit's information is stored on three MTrees, but there is sharing among those MTrees, so the actual total would be less than simply adding up the space used by the Tenant Unit.

Schedules may be consolidated on multiple Data Domain and PowerProtect systems, as follows:

• If two or more schedules have the same name, type, and schedule (for example, "every Monday at 7 AM"), DDMC displays one schedule that is configured on different systems.
• If two schedules have the same name, but different types or different scheduled times, DDMC displays two schedules.
• If a schedule is Disabled on one system, but Enabled on another, DDMC displays one schedule.

NOTE Refresh can take up to one hour if these changes are made through the command-line interface (CLI).

1. Select Capacity > MTrees > Physical Capacity Measurement menu > Schedules
   In Classic view, select Capacity > Utilization > MTree tab > Physical Capacity Measurement menu > Schedules.
2. In the Manage Measurement Schedules dialog, you can add a new schedule, edit an existing schedule, or delete a schedule.
3. For existing schedules, expand the arrow at the left to display the entities that belong to the selected schedule:
   • Schedule shows the current schedule, such as Daily at 12:00.
   • Type can be MTree, Tenant Unit, or Tenant.
   • Status indicates whether the schedule is Enabled or Disabled. If disabled, it will not run at the scheduled time.
     NOTE If the schedule was enabled on some systems and disabled on others, selecting Enable will enable it on all systems. Likewise, selecting Disable will disable it on all systems.
   • In Use displays Yes if any entities are assigned to this schedule.
4. Select Close when you are finished.
