Dell PowerStore Protecting Your Data

When performing DRT, it is not recommended to simulate a network failure between the local and remote systems, and then perform an unplanned failover to the destination system to enable access to the DR NAS server. Since there is no communication between the systems, PowerStore cannot ensure that both NAS servers are in a compatible state. After connection is restored, both NAS servers are in production mode (split brain). As a result, both systems switch to maintenance mode to prevent data from being written to both locations.

To resolve this state, Technical Support intervention is required.
