Start a Virtual Infrastructure Workload Domain

You start the management components for a VI workload domain in a specific order to provide the necessary infrastructure, networking, and management services.
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

After you start up the VI workload domain, verify that the main functionality of the management components is working according to the requirements. See Operational Verification of VMware Cloud Foundation. If your environment runs vSphere Replication and Site Recovery Manager, see also Site Protection and Disaster Recovery for VMware Cloud Foundation.

Start vCenter Server for a Virtual Infrastructure Workload Domain

Use the vSphere Client to power on the vCenter Server appliance in the management domain. If the VI workload domain contains a vSAN cluster, check its health status too.
  1. Log in to the management domain vCenter Server at
    https://<vcenter_server_fqdn>/ui
    as
    administrator@vsphere.local
    .
  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.

Start the ESXi Hosts in a Virtual Infrastructure Workload Domain

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.
  1. Power on the first ESXi host in the 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.

Restart the vSAN Clusters in a Virtual Infrastructure Workload Domain

You start vSAN in a VI workload domain by restarting the vSAN cluster.
Verify that all ESXi hosts in the cluster are connected to the workload domain vCenter Server.
You perform this operation on all vSAN clusters in all VI workload domains.
  1. Log in to vCenter Server for the management or VI workload domain at
    https://<vcenter_server_fqdn>/ui
    as
    administrator@vsphere.local
    .
  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. Restart the vSAN cluster.
    1. Right-click the vSAN cluster and select
      vSAN
      Restart cluster
      .
    2. In the
      Restart Cluster
      dialog box, click
      Restart
      .
      The
      vSAN Services
      page on the
      Configure
      tab changes to display information about the restart process.
  4. After the cluster has restarted, check the vSAN health service and resynchronization status, and resolve any outstanding issues.
    1. Select the cluster 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, under
      vSAN
      Resyncing objects
      , verify that all synchronization tasks are complete.
  5. If you have added the
    root
    user of the ESXi hosts to the Exception Users list for lockdown mode during shutdown, remove the user from the list on each host.
    1. Select the host in the inventory and click the
      Configure
      tab.
    2. In the left pane, select
      System
      Security Profile
      .
    3. In the
      Lockdown Mode
      pane, click the
      Edit
      button.
    4. On the
      Exception Users
      page, from the vertical ellipsis menu in front of the
      root
      user, select
      Remove User
      and click
      OK
      .
  6. If your VI workload domain has multiple vSAN clusters that you shut down, for each cluster, activate the restart option and perform the restart operation.
    1. To be able to restart the next vSAN cluster in the domain, follow
      Scenario 3
      in VMware knowledge base article 87350.
      After the first cluster is started by using the vSAN shutdown cluster wizard, all the other vSAN clusters are labelled as
      Started
      . As a result, the vSAN shutdown cluster wizard is not available for them.

Start the vSphere Cluster Services

You start the vSphere Cluster Services (vCLS) virtual machines in a VI workload domain to provide the availability of vSphere DRS and vSphere HA to the workloads running on the clusters in the workload domain.
  1. Log in to vCenter Server for the management or VI workload domain at
    https://<vcenter_server_fqdn>/ui
    as
    administrator@vsphere.local
    .
  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-c
    8
    :eef257af-fa50-455a-af7a-6899324fabe6/summary
    You copy only
    domain-c8
    .
  5. In the
    Host and Clusters
    inventory, select the vCenter Server instance for 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 start-the-virtual-infrastructure-workload-domain-operations.html#GUID-7319EFCB-7C4D-40CA-A597-42B7F795BC6B_STEP_bdc8d04e-140c-4ee7-a6b4-536577523e7f-en and set it to
    true
    .
  8. Click
    Save
  9. Repeat the procedure on all clusters in the other workload domains.

Start the NSX Manager Virtual Machines

You begin powering on the NSX infrastructure in the management domain or in a VI workload domain by starting the three-node NSX Manager cluster by using the vSphere Client.
  1. Log in to the management domain vCenter Server at
    https://<vcenter_server_fqdn>/ui
    as
    administrator@vsphere.local
    .
  2. In the
    VMs and templates
    inventory, expand the management domain vCenter Server tree and expand the management domain data center.
  3. Power on the NSX Manager nodes for the management domain or the VI workload domain.
    1. Right-click the primary NSX Manager node and select
      Power
      Power on
      .
    2. Repeat the steps to power on the remaining NSX Manager nodes.
    This operation takes several minutes to complete until the NSX Manager cluster becomes fully operational again and its user interface - accessible.
  4. Log in to NSX Manager for the management domain or VI workload domain at
    https://<nsxt_manager_cluster_fqdn>
    as
    admin
    .
  5. Verify the system status of NSX Manager cluster.
    1. On the main navigation bar, click
      System
      .
    2. In the left pane, navigate to
      Configuration
      Appliances
      .
    3. On the
      Appliances
      page, verify that the NSX Manager cluster has a
      Stable
      status and all NSX Manager nodes are available.

Start the NSX Edge Nodes

You continue powering on the NSX infrastructure in the management domain or in a VI workload domain by starting the NSX Edge nodes by using the vSphere Client.
  1. Log in to vCenter Server for the management or VI workload domain at
    https://<vcenter_server_fqdn>/ui
    as
    administrator@vsphere.local
    .
  2. In the
    VMs and templates
    inventory, expand the tree of workload domain vCenter Server and expand data center for the workload domain.
  3. Right-click an NSX Edge virtual machine from the edge cluster and select
    Power
    Power on
    .
    This operations takes several minutes to complete.
  4. Repeat these steps to power on the remaining NSX Edge nodes.
