Modify the roles of the clusters in a replication group.
Prerequisites
- The replication group can be modified only for the default cluster.
- During service provisioning, you are advised not to change the role of a site. Otherwise, service failure may occur.
Procedure
- Choose Data Protection > Configuration > Cross-Site DR > Replication Group.
- In the function pane, select a desired replication group from the list on the left and choose Operation > Modify in the upper right corner.
The Modify XXX page is displayed on the right.
- Change the type of the cluster in the replication group and the passive cluster (auto takeover).
- There must be at least one active cluster.
- If only one active cluster is selected, you can specify a passive cluster among all selected passive clusters to automatically take over services in case of a fault of the active cluster.
- Click OK.
- If the passive cluster (auto takeover) is modified, a high-risk message will be displayed. Confirm your operation as prompted.
