For high-availability deployments, in which multiple appliances are deployed and configured behind a load balancer, ensure that the vco-server service is disabled on each vCloud Automation Center Appliance or vRealize Appliance in your current deployment before you begin the upgrade.
About this task
Do not perform these steps if you are upgrading a minimal deployment.
- Log in to the vCloud Automation Center Appliance or vRealize Appliance of your current deployment with SSH or log in to the virtual machine console.
- Verify that SSH is enabled.
- Log in to the management console by using its fully qualified domain name https://va-hostname.domain.name:5480/, the user name root, and the password you specified when you deployed the appliance.
- Click the Admin tab.
- Verify that SSH service enabled and select Administrator SSH login are selected.
Selecting the SSH service enabled checkbox enables SSH access for all but the root user. Selecting Administrator SSH login enabled allows SSH login by the root user.
- (Optional) If SSH is not enabled, select the checkboxes for SSH service enabled and Administrator SSH login on the Admin tab and click Save Settings.
- Disable the vco-server service.
service vco-server stop chkconfig vco-server off
Perform this step for each appliance in your current deployment and for your PostgreSQL virtual appliance if it was configured from a vCloud Automation Center Appliance or an earlier version of a vRealize Appliance.
- Verify that the service is stopped. The returned status should be NOT RUNNING.
service vco-server status
- Stop vcac-server, apache2, and rabbitmq-server services on each vCloud Automation Center Appliance or vRealize Appliance.
Do not perform this step for the first node you plan to update.
service vcac-server stop service apache2 stop service rabbitmq-server stop
- Verify that the services are stopped. The returned status for each service should be NOT RUNNING.
service vcac-server status service apache2 status service rabbitmq-server status
Do not reboot the appliance or start these services until after you have upgraded each vCloud Automation Center Appliance or vRealize Appliance. Do not stop the vcac, apache, and rabbitmq services on the first node you plan to update.
