Cause

The issue happens when the cassandra service is in an inactive state which prevents the appliance node from fully starting up.

Resolution

To resolve the issue, follow the steps below:

1. Check the status of the Cassandra node(s):
sudo service cassandra status
2. Start the Cassandra services in order to allow the VCD appliance to start up:
sudo service cassandra start
3. Start the VCD Appliance after Cassandra is online:
service vmware-vcd start
