You restore OpenStack by using the Integrated OpenStack Manager web interface.

Prerequisites

  • Ensure that you have your networks, and vCenter Server environment ready. For more information, see section Preparing Your Environment.
  • Ensure that you have installed Install the VMware Integrated OpenStack Virtual Appliance.
  • In vSphere, take a snapshot of the Integrated OpenStack Manager virtual machine. You need this snapshot to for deleting and recreating your deployment.
  • Verify that all required clusters and datastores are available. If you add any resources to your vSphere environment after starting the deployment wizard, for you to see the changes, you must close and reopen the wizard.
  • Verify that you have set the DNS server correctly and that the network gateway or the firewall forwards DNS requests on private networks.
  • For NSX-T Data Center deployments, obtain the values of the following parameters:
    • FQDN or the IP address of the NSX Manager.
    • User name and password to access the NSX Manager.
    • Overlay transport zone.
    • VLAN transport zone.
    • Tier-0 router.
    • DHCP profile.
    • Metadata Proxy Server and secret.
  • For NSX Data Center for vSphere deployments, obtain the values for the following parameters:
    • FQDN or the IP address of the NSX Manager.
    • User name and password to access the NSX Manager.
    • Transport zone.
    • Edge cluster.
    • Resource pool and datastore for the edge cluster.
    • Distributed switch for NSX Data Center for vSphere.
    • Port group for the external network.
    • Port group for the metadata service network (if independent from the management network).

Procedure

  1. Log in to the Integrated OpenStack Manager web interface as the admin user.

    You can access the web interface by opening the IP address of the Integrated OpenStack Manager in a web browser. To find the IP address, select the Integrated OpenStack Manager virtual machine in the vSphere Client and view the Summary tab.

  2. Select OpenStack Deployment, and click Restore.
  3. Specify the deployment name, deployment mode, number of controllers, and controller size. For non-HA mode, you can deploy with one medium or large controller. For HA mode, you can deploy with three or five controllers of any size.

    After deployment, you can scale out your control plane and convert non-HA deployments to HA mode. However, you cannot scale in your control plane or convert HA deployments to non-HA mode.

  4. Click Next.
  5. Enter the FQDN or IP address of your management vCenter Server instance specify its administrator credentials.
    Note: If you want to deploy VMware Integrated OpenStack with NSX Data Center for vSphere networking, you must enter the location of the vCenter Server instance in the format in which it was registered with NSX Manager. To find the correct format, log in to NSX Manager, click Manage vCenter Registration, and view the vCenter Server section. Ensure that the value entered in VMware Integrated OpenStack is the same as the value displayed in the vCenter Server section in NSX Manager.
  6. If the Integrated OpenStack Manager connects to the vCenter Server instance over a private, secure network and you have to disable certificate validation, select the Ignore vCenter Server certificate validation option.
  7. Click Next.
  8. Under Management network, select the management network from the drop-down menu, select whether to enable DHCP, and specify an IP address for the private OpenStack endpoint.
    Note: If you disable DHCP, you must enter the details for the following options:
    • One, or more IP address ranges for the network .
    • Subnet mask for the range.
    • The gateway address.
    • One or more DNS servers .
    • You cannot include the IP address of the private OpenStack endpoint in any of the IP address range specified for the management network.
  9. Under API network, select the API access network from the drop-down menu, select whether to enable DHCP, specify an IP address for the public OpenStack endpoint and optionally specify a public hostname.
    Note: If you disable DHCP, you must enter the details for the following options:
    • One, or more IP address ranges for the network .
    • Subnet mask for the range.
    • The gateway address.
    • One or more DNS servers .
    • You cannot include the IP address of the private OpenStack endpoint in any of the IP address range specified for the API access network.
    • After the initial deployment, you cannot change the public hostname for the public OpenStack endpoint.
  10. Under Control plane resources, select the vSphere data center, resource pool, and datastore that you want to use for the OpenStack control plane.
    Note: You cannot change the datastore after you deploy the control plane.
  11. Under Persistent storage, select a datastore and click Next.
  12. Specify the Content Library Item name, description, Content Library Name and click Next.

Results

The Integrated OpenStack Manager begins to restore your OpenStack cloud, and the status of the deployment is displayed as Provisioning. When the status changes to Running, you can see the finished deployment.
