You power off the second rack first. You first power off the rack's management domain's virtual machines in a specific sequence, and then the rack's ESXi hosts.

Before you begin

Verify you have met the prerequisites described in Power Off a Dual-Rack Cloud Foundation Environment and Power It Back On.

Procedure

  1. Launch the vSphere Web Client to the vCenter Server instance for the second rack's management domain.
    1. In the SDDC Manager client, open the domain details for the second rack's management domain.
    2. Click the launch link (Launch link icon that indicates a link in the EVO SDDC Manager UI launches another web UI) for the vCenter Server instance that is displayed in the domain details window for that management domain.

      A new browser tab opens and displays the vSphere Web Client.

  2. In the vSphere Web Client, locate the VMs for the second rack's management domain.
    1. Navigate to the Hosts and Clusters view.
    2. In the left hand navigation for the Hosts and Clusters view, expand the cluster that has the name beginning with rack-2-vc-1 until you see that cluster's VMs.
  3. Power off these VMs in that cluster whose name begins with rack-2-vc-1 in the following sequence, making sure that each VM's console is completely shut down before powering off the next VM.
    Note:

    For each VM, verify that it is the one in the second rack's management domain by looking at its Summary tab in the vSphere Web Client and verifying that its DNS name begins with rack-2-.

    • The three NSX controllers

    • The vRealize Operations Manager instance

    • The NSX Manager instance

    • The SDDC Manager instance for the second rack's management domain

  4. In the vSphere Web Client, use the vCenter Server instance's Summary tab to determine which ESXi host that VM is running on.

    This vCenter Server instance has the DNS name beginning with rack-2-vc-1.

  5. Use the vSphere Web Client to locate the IP address for that ESXi host.
  6. Using the ESXi host's IP address in the URL for the VMware Host Client, open the login screen for the VMware Host Client.

    The URL to open the VMware Host Client to that ESXi host has the form https://esxi-host-ip/ui/.

  7. Log in to the VMware Host Client using the ESXi host's root account credentials.
  8. In the VMware Host Client, navigate to see the vCenter Server instance whose name begins with rack-2-vc-1.
  9. Power off that vCenter Server instance.
  10. Log out of the VMware Host Client.
  11. Open the VMware Host Client to the second rack's N0 ESXi host, using that host's FQDN in the browser: https://rack-2-N0.subdomain.root-domain/ui/, where subdomain and root-domain are the ones for your Cloud Foundation environment.
  12. Log in to the VMware Host Client using the host's root account credentials.
  13. In the VMware Host Client, power off that ESXi host by right-clicking Host and clicking Shut down.
  14. In sequence, repeat steps 11 through 13 to shut down the remaining ESXi hosts in the second rack: N1, N2, N3, and so on.
