High availability failback for the Conductor
After a failover has occurred, once the original Conductor becomes available again, or once a replacement is in place, you need to perform a failback to re-establish the high availability pairing.
If a replacement Conductor is required, follow the steps in Set up Conductor high availability to set up the replacement unit as the new standby Conductor.
Note: If the new Conductor
will use different IP addresses than what the failed unit used, you need to re-configure the
current master Conductor
before proceeding with the failback.
If the original master Conductor can be brought back
online without replacing, it can be easily switched to become the new standby. To do this,
- Log in to the master Conductor,
- In Settings, under Conductor High Availability, click Edit Settings.
- In Conductor HA Configuration, click Demote to standby to transition the Conductor to become the standby.
This Conductor now connects to the master Conductor and initializes the data replication. The replication may take several minutes, depending on the number of HIPservices in the master database and the network bandwidth available.
Once you complete the setup, the standby Conductor reboots and you are directed to the Settings page.
Note: You may have to re-authenticate on the new standby Conductor once the setup is
complete. If the configuration was successful, the Conductor displays standby-mode
in the top menu bar.
