Dell Storage Manager 2020 R1 Administrator's Guide

Step 3: An Administrator Activates Disaster Recovery

An administrator activates DR to make the data in the destination volume accessible. When DR is activated, Dell Storage Manager brings the destination volume on line and maps it to a server at the DR site. The server sends IO to the activated DR volume for the duration of the source site outage.
