You power on all of the switches in the dual-rack installation first. Then you power on the first rack starting with its ESXi hosts, followed by its management domain's virtual machines in a specific sequence.

Prerequisites

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

Procedure

  1. Power on the switches in all racks in the specified sequence.
    1. Inter-rack switches
    2. ToR switches
    3. Management switches
  2. Use the switch consoles to verify that all switches are up.
  3. Boot up the ESXi hosts physically or through a remote console session to exit maintenance mode.
    1. On each host, connect and log in to the ESXi console.
    2. Use the following CLI command to exit maintenance mode.
      # esxcli system maintenanceMode set -e false
  4. Power on the VMs on the first rack in the following order.
    1. Both Platform Services Controllers

    2. vCenter Server for management domain

    3. SDDC Manager Controller VM

    4. SDDC Manager Utility VM

    5. vRealize Log Insight

    6. NSX Manager

    7. NSX Controller 1

    8. NSX Controller 2

    9. NSX Controller 3

    10. vCenter Server for the workload domains

  5. Log in to the SDDC Manager Dashboard to verify that it displays correctly.
  6. Power on the hosts in rack 2 starting from host 0, host 1, and so on.
  7. Take the hosts on rack 2 out of maintenance mode.
    1. On each host, connect and log in to the ESXi console.
    2. Use the following CLI command to exit maintenance mode.
      # esxcli system maintenanceMode set -e false
  8. Repeat steps 6 and 7 on each additional rack in the system.
  9. Power on the workload VMs.
  10. If you have VDI workload domains, log in to VDI Manager to verify it displays correctly.
  11. Confirm that SDDC Manager still displays correctly.
  12. Using the root account, SSH in to the SDDC Manager Controller VMand run the ./sos --health-check command to verify that everything works correctly.

Results

Note:

After the VMs for the first rack's management domain are up, but before the second rack is powered on, the web interfaces to the vCenter Server instance, and the vRealize Log Insight instance are partially accessible. They will be fully accessible after you power on the second rack.
