After powering off the secondary rack, you power down the primary rack's management domain's virtual machines in a specific sequence, and then the rack's ESXi hosts.

Prerequisites

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 primary rack's management domain.
    1. In the SDDC Manager client, open the domain details for the primary 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. Place the hosts for each workload domain in maintenance mode.

    You must use the CLI command that supports setting thevSAN mode when entering maintenance mode.

    1. On each host, connect and log in to the ESXi console.
    2. Place the host into maintenance mode using the following command, with the noAction option included.
      # esxcli system maintenanceMode set -e true -m noAction
    3. Shut down all the ESXi hosts in the workload domain.
  3. Shut down the VMs in the management domain in the following sequence.
    1. SDDC Manager Utility VM

    2. The three NSX Controllers

    3. vRealize Log Insight

    4. NSX Manager

    5. SDDC Manager Controller VM

    6. vCenter Server for management domain

    7. vCenter Server for the workload domains

    8. Both Platform Services Controllers

  4. Place the management domain hosts in maintenance mode.

    You must use the CLI command that supports setting thevSAN mode when entering maintenance mode.

    1. On each host, connect and log in to the ESXi console.
    2. Put the host into maintenance mode using the following command, with the noAction option included.
      # esxcli system maintenanceMode set -e true -m noAction
    3. Shut down all the ESXi hosts in the workload domain.
  5. Shut down the unmanaged hosts in the system, if any.
  6. Shut down the switches in the specified order. For a Cumulus switch, log in first and then shut it down.
    1. ToR switches in each rack

    2. Inter-rack switches in rack 2.

    3. Management switches in each rack.
