Perform this procedure to switch Presence Server elements to the secondary server.
Procedure
Create a backup of the Presence Server data after the failover to be invoked manually by an operator after the failover of System Manager.
Run the changeSMGRFQDN.sh script on the Presence Server element to change the Presence Server System Manager configuration from the primary System Manager to the secondary System Manager.
The script changes all configurations on the Presence Server element but does not affect Presence Server entries or configuration on System Manager. Presence Server calls InitTM to establish trust with the secondary System Manager. The element is re-registered on the secondary System Manager. The element is registered in DRS and Services > Inventory. As part of the registration, the Presence Server element is added in /etc/hosts of the secondary System Manager. DRS marks the element for repair and sends the initial load of data to the element. Data on System Manager overwrites data on Presence Server element.
Log out or log in to the endpoints on failover.
Create a backup of the Presence Server element after System Manager failover to ensure that the new configuration data is backed up.
To ensure continued serviceability support during primary nonoperational scenarios, configure Presence Server elements with primary and secondary System Manager servers as trap destinations.
For instructions to configure trap destinations on Presence Server element, see Administering Avaya Aura®Presence Services.
