By using the appliance management interface, change its IP address, then by using the Replicator Service management interface, update the traffic control settings then restart the appliance services. By returning to the appliance management interface, repair the local Replicator Service and update the Service Endpoint address. Finally, repair from the remote site by using the updated Service Endpoint address.

Note: Applying any network changes can lead to temporary network outages. For example, the browser connectivity to the management interface is interrupted when being accessed through the network adapter that is being reconfigured.
This procedure applies to the following appliance roles:
  • VMware Cloud Director Availability On-Premises Appliance roles:
    • On-Premises to Cloud Director Replication Appliance
    • On-Premises to Cloud vCenter Replication Appliance
and for
  • vCenter Replication Management Appliance

For information about changing the appliance address in a cloud site backed by VMware Cloud Director, see Network Settings Configuration.

Prerequisites

Verify that VMware Cloud Director Availability 4.4 is deployed in the vCenter Server site.

Procedure

  1. Log in to the management interface of the VMware Cloud Director Availability 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.
  2. Change the appliance network adapter IP address.
    1. In the left pane, click Settings.
    2. Under Appliance settings, expand the Network section.
      You can see all the network adapters that are added to the appliance.
    3. Next to the adapter name which needs changing the IP address, click Edit.
    4. In the Settings window for the selected adapter, configure its network settings and click Apply.
      Option Description
      IP Mode Select IPv4, IPv6, or Unconfigured

      By selecting Unconfigured, you turn off this adapter and delete all its settings, including static routes. Use this cleanup procedure, in case there are configuration leftovers that are causing unexpected network behavior.

      Type:

      DHCP
      If you select DHCP to provide the network configuration, all manually configured network settings, such as DNS servers, search domains, static routes, and MTU size are removed.
      Type: Static Enter the static configuration.
      1. In the Address/Prefix text box, enter a CIDR address - IP address, followed by a forward slash and a network mask or a prefix length. For example, enter 10.20.30.41/21.
      2. In the Gateway text box, enter a gateway that is in the same network as the provided IP address. For each IP mode, you can use only one default gateway. If you are configuring a second adapter in the same IP mode, you must not enter a default gateway.
      3. In the MTU (bytes) text box, enter the maximum transmission unit size in bytes. The default is 1500 bytes.
      The updated IP address applies, showing a continuously spinning progress indicator until you go to the management interface by using the new IP address.
  3. Log in to the management interface of the local Replicator Service by using the new IP address of the appliance.
    1. In a Web browser, go to https://Appliance-New-IP-Address:8043/ui/admin.
      Cancel selecting certificates for login displayed by your browser.
    2. Select Appliance login or SSO login and enter the root or the single sign-on user credentials.
    3. Click Login.
  4. Update the Traffic Control addresses then restart the services of the appliance.
    1. In the left pane, click Settings.
    2. Under Appliance settings, next to the Traffic Control section, click Edit.
    3. In the Traffic Control window, select the new IP address of the network adapter.
      Option Description

      Management Address

      Select the new IP address for the network adapter.

      NFC Address

      Select the new IP address for the network adapter.

      LWD Address

      Select the new IP address for the network adapter.
    4. In the left pane, click System Health.
    5. On the System health page, to restart all the appliance services, click Restart service.
      The web interface logs out your browser session. After the services restart in a few minutes, the page reloads.
      Note: This step completes changing the IP address of:
      • On-Premises to Cloud Director Replication Appliance is now configured with the new IP address.
      Complete the remaining steps only when configuring new IP address for one of the following appliance roles:
      • On-Premises to Cloud vCenter Replication Appliance
      • vCenter Replication Management Appliance
  5. Log in back to the management interface of the VMware Cloud Director Availability appliance.
    1. In a Web browser, go to https://Appliance-New-IP-Address/ui/admin.
    2. Select Appliance login or SSO login and enter the root or the single sign-on user credentials.
    1. Click Login.
  6. Repair the local auto-paired Replicator Service on the appliance by updating the Service Endpoint address then restart the appliance services.
    1. In the left pane, click Replicator Services.
    2. Select the local Replicator Service of the appliance and click Repair.
    3. In the Details for the Replicator Service window, update the Service Endpoint address with the new IP address and click Apply.
      Option Description

      Endpoint Address

      Enter the new IP address for the Service Endpoint of this appliance.

      Appliance Password

      Enter the password for the appliance root user.

      SSO Admin Username

      Enter the vSphere administrator user name for the vCenter Server Lookup service that belongs to the ADMINISTRATORS group.

      SSO Password

      Enter the vSphere administrator password for the vCenter Server Lookup service.

      Verify the thumbprint and accept the SSL certificate. The updated endpoint address applies, showing a continuously spinning progress indicator. If you missed restarting the appliance services in the previous step, you must retry this step after restarting them or you see: Generic network error occurred at the client side.
    4. In the left pane, click System Health.
    5. On the System health page, verify that all connectivity statuses show green OK.
  7. Update the Service Endpoint of the appliance with the new IP address.
    1. In the left pane, click Settings.
    2. Under Service endpoints, next to Service Endpoint Address click Edit.
    3. In the Service Endpoint address window, enter the new IP address and click Apply.
  8. Update the new Service Endpoint address in the paired remote site.
    If the Service Endpoint address changed before any initial pairing with a remote site, skip this step.
    1. From the remote site, in the left pane click Peer Sites.
    2. Select the site with updated Service Endpoint address and click Repair.
    3. In the Update Pairing window, click Update.
    4. Verify the thumbprint and accept the SSL certificate of the site.
    The remote paired site uses the new Service Endpoint address.

Results

The VMware Cloud Director Availability appliance now uses the new IP address.
