Restarting HDR or RS clusters after a network failure

After a network failure, the HDR or RS cluster might need to be restarted. After a network failure, the primary database server is in online mode, and the secondary database server is in read-only mode. Replication is turned off on both database servers (state = off).

Restarting the cluster might not be necessary because the primary database server attempts to reconnect every 10 seconds and displays a message regarding the inability to connect every 2 minutes.

If the cluster does not restart automatically, when the connection is reestablished, you can restart the cluster by running the following commands on the secondary server:
onmode -d secondary primary_name
