Once SDN-C pod is up and running (might take up to 5~7 minutes), the akka.conf should be updated with IP addresses configured in values.yaml for ODL clustering.
- Log in to one of the SDN-C pods and check the akka.conf from /opt/opendaylight/current/configuration/initial/:Info title Example akka.conf odl-cluster-data {akka {remote {artery {enabled = offcanonical.hostname="10.147.114.5"canonical.port = 30251}netty.tcp {bind-hostname="10.36.0.3"bind-port = 2550hostname="10.147.114.5"port = 30251}# when under load we might trip a false positive on the failure detector# transport-failure-detector {# heartbeat-interval = 4 s# acceptable-heartbeat-pause = 16s# }}cluster {# Remove ".tcp" when using artery.seed-nodes = ["akka.tcp://opendaylight-cluster-data@10.147.114.5:30251","akka.tcp://opendaylight-cluster-data@10.147.114.5:30252","akka.tcp://opendaylight-cluster-data@10.147.114.5:30253","akka.tcp://opendaylight-cluster-data@10.147.114.140:30251","akka.tcp://opendaylight-cluster-data@10.147.114.140:30252","akka.tcp://opendaylight-cluster-data@10.147.114.140:30253"]roles = ["member-1"]}persistence {# By default the snapshots/journal directories live in KARAF_HOME.

To test ODL clustering:
Using Jolokia RestConf API
Run the Jolokia RestConf restConf read API to review ODL cluster details like "PeerAddresses", "PeerVotingStates", "Voting", "ShardName", "FollowerInfo" "Leader" for any shard. Use user: admin, password: admin to access.
To list shards, use below API:
