Manual Switch Over

If the onedb-server-1 server is the HDR primary and onedb-server-0 server is the HDR secondary you can switch these two roles when automatic failover is disabled by doing the following. Login to the onedb-server-0 server (current HDR Secondary) and perform the failover operation by running the following command:
onmode –d make primary onedb0
If TLS is enabled for the OneDB HA cluster use the following command:
onmode –d make primary onedb0_ssl
