Solution

Procedure

  1. Navigate to /opt/Avaya/DeviceServices/<version>/CAS/<version>/config and check the install.properties file.

    The files at both the nodes should have the same value for SEED_NODE.

  2. If the values are different, uninstall Avaya Aura® Device Services from all nodes.
  3. Run the Avaya Aura® Device Services binary installer as described in Deploying Avaya Aura® Device Services.
