  1. Once the Unity processes have started, check the states of the Sequencers: /opt/teradata/unity/bin/unityadmin -u admin -P admin -e "sequencer status"
  2. Ensure that the HA Status is Peer. If HA Status is not Peer, go to the next step.
  3. Check the Individual Sequencer States. If one of the Sequencer processes is not in the Active state and the other in the Standby state, go to the next step.
  4. Ensure the following:
    • Both Sequencer processes have started and are running.
    • Each Unity server can access the other Unity server.
    • At least one of the Watchdog processes is running.
