<div id="body8662426"><div class="section" id="evs_04_2054__en-us_topic_0079692914_section58179688"><h4 class="sectiontitle">Function</h4><p id="evs_04_2054__p54922514105836">This API is used to perform a failover for a replication consistency group. When an exception occurs in the primary AZ, a failover can be performed to change the primary site of a replication consistency group from the primary AZ to the secondary AZ and enable DR ECSs and DR disks in the secondary AZ to provide services.</p>
|
|
<p id="evs_04_2054__p23524008162736">After the failover, the <strong id="evs_04_2054__b84235270619392">replication_status</strong> value of the replication consistency group is <strong id="evs_04_2054__b842352706193859">active-stopped</strong>. In this case, EVS replication is available only after the primary AZ is restored and the replication consistency group is synchronized.</p>
