Dell PowerStore Protecting Your Data

When you resume a preferred, paused metro resource, the preferred system starts synchronizing data with the nonpreferred system. After synchronization is complete, the metro resource status returns to an active/active state.

When you resume a promoted (previously nonpreferred), paused metro resource, the nonpreferred system starts synchronizing with the preferred system (Reprotecting state) to return to active/active state.

If the nonpreferred system was promoted, resuming the metro resource from the promoted nonpreferred system synchronizes data from the promoted nonpreferred system to the preferred.
