Changing the seed node of a cluster

Last Updated : Jun 05, 2026 |

About this task

Use this procedure to change the seed node only if you need to decommission the seed node. If you are not installing a new node but assigning the seed node function to an existing node, follow the procedure starting with Step 2.

Note:

Before running the setSeedNode script, disable the virtual IP on the node so that the new seed node can be set as the virtual IP master afterwards.

Procedure

  1. Install the new node as an additional cluster node.
  2. Log on to the new node and run the setSeedNode.sh script.
    For example: 
    sudo /opt/Avaya/DeviceServices/<version>/CAS/<version>/misc/setSeedNode.sh
  3. Log on to each of the other cluster nodes and run the setSeedNode.sh script with the IP address of the new seed node as a parameter.
  4. Restart the Avaya Aura® Device Services service on the new seed node. 
    svc aads restart
  5. Restart the Avaya Aura® Device Services service on the other cluster nodes. 
    svc aads restart

Next Steps

  • Disable the virtual IP on the old seed node.

  • Configure the new node to be the virtual IP Master node. The initial node of the cluster is usually designated as the virtual IP master node.
