In certain cases, for example, during hardware or power maintenance of the data center, you must shut down the virtual machines deployed by vSphere with Tanzu in a VMware Cloud Foundation environment in a way that prevents data loss and appliance malfunction, and start it up restoring component integration after the maintenance operation is over.

Shut Down the Virtual Machines of vSphere with Tanzu for Private AI Ready Infrastructure for VMware Cloud Foundation

Shut down the Supervisor control plane virtual machines, Tanzu Kubernetes Cluster control plane and worker virtual machines, and the Harbor virtual machine in the vSphere with Tanzu workload domain.

For the full-stack shutdown order of VMware Cloud Foundation and of a VI workload domain with vSphere with Tanzu, see Shutting Down VMware Cloud Foundation.

Procedure

  1. Shut down the Supervisor control plane virtual machines.
    1. Log in to the ESXi host that runs the first Supervisor control plane virtual machine at https://<esxi_host_fqdn> as root.
    2. In the navigation pane, click Virtual Machines.
    3. Right-click the supervisor control plane virtual machine, and select Guest OS > Shut down.
    4. In the confirmation dialog box, click Yes.
    5. Repeat the steps to shut down the remaining Supervisor control plane virtual machines on the workload domain ESXi hosts which run them.
  2. To shut down the Tanzu Kubernetes Cluster control plane and worker virtual machines, repeat the previous step on the ESXi hosts that are running these machines.

    Start with the first Tanzu Kubernetes Cluster control plane virtual machine.

  3. Shut down the Harbor virtual machines.
    1. Log in to the ESXi host that runs the first Tanzu Kubernetes Cluster control plane virtual machine at https://<esxi_host_fqdn> as root.
    2. In the navigation pane, click Virtual machines.
    3. Right-click the Harbor virtual machine and select Power > Power off.
    4. In the Warning dialog box, click Yes.
    5. Repeat the procedure to power off the remaining Harbor virtual machines on the ESXi hosts that run them.

Start the vSphere with Tanzu Virtual Machines for Private AI Ready Infrastructure for VMware Cloud Foundation

The virtual machines that are deployed by vSphere with Tanzu for running containerized workloads over Kubernetes are automatically started by vCenter Server after vCenter Server and NSX for the VI workload domain are back online.
