You start the management components for a VI workload domain with vSphere with Tanzu in a specific order to provide the necessary infrastructure, networking, and management services before powering on the components for containerized workload management.

You start the management components for the management domain first. Then, you start the management components for the VI workload domains and the customer workloads.

If the NSX Manager cluster and NSX Edge cluster are shared with other VI workload domains, follow this general order:

  1. Start the other VI workload domains.
  2. Start the VI workload domain that runs the shared NSX Edge nodes.
  3. Start the customer workloads that rely on NSX-T Data Center services.

Verify the Operational State of the VI Workload Domain with vSphere with Tanzu

After you start up the management domain, verify that the main functionality of the management components is working according to the requirements. See Operational Verification of VMware Cloud Foundation and Developer Ready Infrastructure for VMware Cloud Foundation.

Start vSAN and ESXi Hosts in a Virtual Infrastructure Workload Domain with vSphere with Tanzu

You start the ESXi hosts using an out-of-band management interface, such as, ILO or iDRAC to connect to the hosts and power them on. You then exit maintenance mode for the ESXi hosts and prepare the vSAN cluster for startup.

Procedure

  1. Power on the first ESXi host in the VI workload domain.
    1. Log in to the first ESXi host in the workload domain by using the out-of-band management interface.
    2. Power on the ESXi host according to the hardware vendor guide.
  2. Repeat the previous step to start all the remaining ESXi hosts in the workload domain.

    This operation takes several minutes to complete.

  3. If your VMware Cloud Foundation environment has several VI workload domains with vSphere with Tanzu, start all ESXi hosts in all these workload domains to save time because the vSAN scan operation which takes place at ESXi startup requires some time to complete.
  4. Turn on SSH on all hosts in the domain by using the SoS utility of the SDDC Manager appliance.
    1. Log in to the SDDC Manager appliance by using a Secure Shell (SSH) client as vcf.
    2. Switch to the root user by running the su command and entering the root password.
    3. Run this command. 
      /opt/vmware/sddc-support/sos --enable-ssh-esxi --domain domain-name
  5. Log in to the first ESXi host in the domain as root by using a Secure Shell (SSH) client.
  6. Take the ESXi host out of maintenance mode by running the command. 
    esxcli system maintenanceMode set -e false
  7. Repeat 5 and 6 on all the remaining ESXi hosts in the domain.
  8. On the first ESXi host in each vSAN cluster, run the command to prepare the vSAN cluster for starting. 
    python /usr/lib/vmware/vsan/bin/reboot_helper.py recover

    The command returns Cluster reboot/poweron is completed successfully!

  9. Verify that all hosts in the vSAN cluster are available by running the command. 
    esxcli vsan cluster get

    Look for the following strings in the output:

    • Local Node Type: NORMAL

    • Local Node Health State: HEALTHY

  10. Turn on vSAN cluster member updates by running the command. 
    esxcfg-advcfg -s 0 /VSAN/IgnoreClusterMemberListUpdates

    The command returns Value of IgnoreClusterMemberListUpdates is 0.

  11. Repeat Step 9 and Step 10 for the remaining ESXi hosts in the workload domain.
  12. Deactivate SSH on the ESXi hosts in the domain from the SDDC Manager appliance.
    1. Log in to the SDDC Manager appliance by using a Secure Shell (SSH) client as vcf.
    2. Switch to the root user by running the su command and entering the root password.
    3. Run this command. 
      /opt/vmware/sddc-support/sos --disable-ssh-esxi --domain domain-name

Start vCenter Server for a Virtual Infrastructure Workload Domain with vSphere with Tanzu

Use the vSphere Client to power on the vCenter Server appliance in the VI workload domain. If the workload domain contains a vSAN cluster, check its health status too.

Procedure

  1. Log in to the management domain vCenter Server at https://<vcenter_server_fqdn>/ui as [email protected].
  2. In the VMs and templates inventory, expand the management domain vCenter Server tree and expand the management domain data center.
  3. Start vCenter Server.
    1. Locate the vCenter Server virtual machine for the VI workload domain.
    2. Right-click the virtual machine and select Power > Power on.

    The startup of the virtual machine and the vSphere services takes some time to complete.

  4. Log in to the VI workload domain vCenter Server at https://<vcenter_server_fqdn>/ui as [email protected].
  5. In the Hosts and clusters inventory, expand the tree of the VI workload domain vCenter Server and expand the data center for the VI workload domain.
  6. Verify the vSAN health and resynchronization status.
    1. Select the vSAN cluster in the VI workload domain and click the Monitor tab.
    2. In the left pane, navigate to vSAN > Skyline health and verify the status of each vSAN health check category.
    3. In the left pane, navigate to vSAN > Resyncing objects and verify that all synchronization tasks are complete.
  7. If a vSAN cluster has vSphere HA turned on by design, start vSphere HA.
    1. Select the vSAN cluster and click the Configuretab.
    2. In the left pane, select Services > vSphere Availability and click the Edit button.
    3. In the Edit Cluster Settings dialog box, turn on vSphere HA and click OK.
  8. Verify that the Kubernetes services are started.
    1. Log in to the VI workload domain vCenter Server by using a Secure Shell (SSH) client as root.
    2. To switch to the Bash shell, run the shell command.
    3. Run the command. 
      vmon-cli -s wcp

      The command returns RunState: STARTED

Start the vSphere Cluster Services for a Virtual Infrastructure Workload Domain with vSphere with Tanzu

You start the vSphere Cluster Services (vCLS) virtual machines in a VI workload domain with vSphere with Tanzu to provide the availability of vSphere DRS and vSphere HA to the workloads running on the clusters in the workload domain.

Perform this operation on all vSAN clusters in the other workload domains with vSphere with Tanzu.

Procedure

  1. Log in to vCenter Server for the management or VI workload domain at https://<vcenter_server_fqdn>/ui as [email protected].
  2. In the Hosts and clusters inventory, expand the tree of the VI workload domain vCenter Server and expand the data center for the VI workload domain.
  3. Select the cluster on which vCLS must be started.
  4. Copy the cluster domain ID domain-c(cluster_domain_id) from the URL of the browser.

    When you navigate to a cluster in the vSphere Client, the URL is similar to this one:

    https://<fqdn-of-vCenter-server>/ui/app/cluster;nav=h/urn:vmomi:ClusterComputeResource:domain-c8:eef257af-fa50-455a-af7a-6899324fabe6/summary

    You copy only domain-c8.

  5. In the Host and Clustersinventory, select the vCenter Server instance for the management domain or the VI workload domain and click the Configure tab.
  6. Under Advanced Settings, click the Edit Settings button.
  7. Locate the config.vcls.clusters.domain-c(number).enabled property for the domain cluster ID from 4and set it to true.
  8. Click Save
