To replace or restore a failing Cloud Tunnel Appliance, power it off, deploy a new instance of the appliance and enable tunneling to the new appliance.

If VMware Cloud Director Availability 4.1 or later is deployed and a backup of the Cloud Tunnel Appliance exists, follow the procedure in Restore the Cloud Appliances instead of the procedure below. To generate a backup in VMware Cloud Director Availability 4.1 or later, see Back Up the Cloud Appliances.

Prerequisites

  • Verify that VMware Cloud Director Availability is deployed in the cloud site.
  • Verify that the existing Cloud Tunnel Appliance is powered off or that it is disconnected from the port group.

Procedure

  1. Deploy a new Cloud Tunnel Appliance.
    1. Use the same host name, IP address, and the remaining settings as the original Cloud Tunnel Appliance.
    2. Power on the new Cloud Tunnel Appliance.
  2. Log in to the Tunnel Service management interface.
    1. In a Web browser, go to https://Tunnel-IP-or-FQDN:8442.
    2. Select Appliance login and enter the root user password that you set during the OVA deployment.
    3. Click Login.
  3. If you log in to the appliance for the first time, you must change the initial root user password.
    1. Enter the initial root user password that you set during the OVA deployment.
    2. Enter and confirm a new password.
      The password that you enter must be a secured password with a minimum of eight characters and it must consist of:
      • At least one lowercase letter.
      • At least one uppercase letter.
      • At least one number.
      • At least one special character, such as & # %.
    3. Click Apply.
      The Getting Started tab opens.
  4. (Optional) To log in to the Tunnel Service by using vCenter Single Sign-On credentials, you can register the new Cloud Tunnel Appliance with the vCenter Server Lookup service.
    1. In the Configuration page, under Service endpoints, next to Lookup Service Address, click Edit.
    2. In the Lookup Service Details window, enter the Lookup Service Address.
      Pressing Tab autocompletes the vCenter Server Lookup service address to https://Lookup-Service-IP-Address:443/lookupservice/sdk.
    3. Click Apply.
    4. Verify the thumbprint and accept the certificate of the vCenter Server Lookup service.
  5. Log in to the management interface of the Cloud Replication Management Appliance.
    1. In a Web browser, go to https://Appliance-IP-Address/ui/admin.
    2. Select Appliance login or SSO login and enter the root or the single sign-on user credentials.
    3. Click Login.
  6. Enable tunneling to the new Cloud Tunnel Appliance.
    1. In the left pane under Configuration, click Settings.
    2. Under Service endpoints, next to Tunnel Service address click Edit.
    3. In the Tunnel Service Settings window, enter the root user password.
      The Tunnel Service Endpoint address is already populated and the Appliance user is set to root.
    4. Click Apply.
    5. Verify the thumbprint and accept the certificate of the Tunnel Service.

Results

The new Cloud Tunnel Appliance starts tunneling for the VMware Cloud Director Availability services communication.

  • For the paired cloud sites, you do not need to perform additional operations. In a few minutes, the pairing reports a green status and the replications proceed according to their RPO.
  • For the paired on-premises sites, the Cloud Service reports a red status for all the pairings incoming from on-premises and outgoing to on-premises. The paired VMware Cloud Director Availability On-Premises Appliance instances continue to report a green status for pairing to cloud and the replications from on-premises to cloud proceed according to their RPO. To restore the replications from cloud to on-premises, you can restart the VMware Cloud Director Availability On-Premises Appliance instances or you can repair all on-premises sites with the cloud site.

What to do next

You can verify that all services are running correctly. For more information, see VMware Cloud Director Availability Operational Verification.
