To maintain uninterrupted service with the System Manager, the FQDN must be updated. Use this procedure to update the System Manager FQDN for a media server cluster, only if the System Manager FQDN has been changed and not the IP address or any other related configuration.
Access the Element Manager (EM) that is configured to manage the Primary node of the Avaya Aura® MS cluster by using the following emergency login URL:
Navigate to SecuritySystem ManagerAdvanced Settings and update Fully qualified domain name (FQDN) of System Manager server with the new System Manager FQDN.
Click Save.
To apply the change on each node of the cluster, access a Linux shell for each media server in the cluster and restart the EM using the command:
ADDITIONAL INFORMATION: service avaya.em restart
Important:
Restart the EM service on every media server in the cluster.
