Verify the High Availability of the VMware Aria Automation Cluster for Private Cloud Automation for VMware Cloud Foundation

Verify that VMware Aria Automation can continue to operate when a member of the cluster becomes unavailable.

Validate that after a member of the cluster becomes unavailable, VMware Aria Automation is operational by logging in with a system account and provisioning cloud templates.

Expected Outcome
You can successfully log in with a system account and perform provisioning operations without any disruptions after a VMware Aria Automation node becomes unavailable.

Procedure

1. Shut down one member of the VMware Aria Automation cluster.

   1. Log in to the management domain vCenter Server at https://<management_vcenter_server_fqdn>/ui as [email protected].

   2. In the VMs and templates inventory, expand the management domain vCenter Server tree and expand the management domain data center.

   3. Expand the VMware Aria Automation virtual machine folder.

   4. Right-click one of the VMware Aria Automation cluster nodes and select Power > Shut down guest OS.

   5. In the Confirm guest shut down dialog box, click Yes.

2. Log in to the VMware Aria Automation cloud services console at https://<aria_automation_cluster_fqdn>/csp/gateway/portal with a user assigned the Service Broker administrator service role.

3. Request a testing deployment.

   1. Under My services, click Service Broker.

   2. In the left pane, select Catalog.

   3. In a cloud template card, click Request.

   4. On the New request page, configure the settings and click Submit.

4. Verify that the testing deployment completes successfully.

   1. In the left pane, select Deployments > Deployments and click the card for the testing deployment.

   2. Click the History tab and click the Request details tab.

   3. Verify that the table shows the applied cloud template constraint tags.

   4. When the testing deployment completes, verify that the deployment card has the Create Successful tag.

5. Power on the VMware Aria Automation cluster node that you powered off.

   1. Log back in to the management domain vCenter Server.

   2. In the VMs and templates inventory, expand the management domain vCenter Server tree and expand the management domain data center.

   3. Right-click the powered-off VMware Aria Automation cluster node and select Power > Power on.

6. Verify the status of the pods on the VMware Aria Automation cluster node that you powered on.

   1. Log in to the VMware Aria Automation cluster node that you powered on by using a Secure Shell (SSH) client as root.

   2. Verify that all pods are Running and Ready by running the command.

      # kubectl -n prelude get pods

7. Repeat this procedure for each of the remaining VMware Aria Automation cluster nodes.
