+= Specifying multiple host groups for your cluster on vSphere
+
+You can configure the `infrastructures.config.openshift.io` configuration resource to specify multiple host groups for your {product-title} cluster that runs on a {vmw-first} instance. This is necessary if your {vmw-short} instance is in a stretched cluster configuration, with your ESXi hosts and storage distributed across multiple physical data centers. Use this procedure if you did not already configure host groups for your {product-title} cluster at installation, or if you need to update your {product-title} cluster with additional host groups. 
+
+:FeatureName: OpenShift zones support for vSphere host groups
+include::snippets/technology-preview.adoc[]
+
+.Prerequisites
+
+* ESXi hosts are grouped into host groups, which are linked via VM-host affinity rules to corresponding virtual machine (VM) groups. See the following example `govc` commands for details:
++
+[source,terminal]
+----
+# This example shows the correct configuration for a cluster with two host groups:
+
+# Create host groups:
+govc cluster.group.create -name <host_group_1> -host
+govc cluster.group.create -name <host_group_2> -host
+
+# Create VM groups:
+govc cluster.group.create -name <vm_group_1> -vm
+govc cluster.group.create -name <vm_group_2> -vm
+
+# Create VM-host affinity rules:
+govc cluster.rule.create -name <rule_1> -enable -vm-host -vm-group <vm_group_1> -host-affine-group <host_group_1> 
+govc cluster.rule.create -name <rule_2> -enable -vm-host -vm-group <vm_group_2> -host-affine-group <host_group_2> 
+
+# Add ESXi hosts to host groups:
+govc cluster.group.change -name <host_group_1> <esxi_host_1_ip> 
+govc cluster.group.change -name <host_group_2> <esxi_host_2_ip> 
+----
+* `openshift-region` and `openshift-zone` tag categories are created on the vCenter server.
+* Compute clusters have tags from the `openshift-region` tag category.
+* ESXi hosts within host groups have tags from the `openshift-zone` tag category. 
+* `Host.Inventory.EditCluster` privilege is granted on the {vmw-short} vCenter cluster object.
+* `TechPreviewNoUpgrade` feature set is enabled. For more information, "see Enabling features using feature gates". 
+
+.Procedure
+
+. Edit the infrastructure settings of your {product-title} cluster.
+
+.. To copy your existing infrastructure settings to a file, run the following command:
++
+[source,terminal]
+----
+$ oc get infrastructures.config.openshift.io cluster -o yaml > <name_of_infrastructure_file>.yaml
+----
++
+.. Edit your infrastructure file to include a failure domain for each host group in your {vmw-short} cluster.  Refer to the following YAML file for an example of this configuration. Ensure you replace any values wrapped in angle brackets (`< >`) with your values:

+[source,yaml]

++
+.. To update your cluster with these changes, run the following command:
++
+[source,terminal]
+----
+$ oc replace -f <name_of_infrastructure_file>.yaml
+----
+
+. Update your `ControlPlaneMachineSet` custom resource (CR) with the new failure domains by completing the following steps:
++
+.. Edit the `ControlPlaneMachineSet` CR by running the following command:
++
+[source,terminal]
+----
+$ oc edit controlplanemachinesets.machine.openshift.io -n openshift-machine-api cluster
+----
++
+.. Edit the `failureDomains` parameter as shown in the following example:

++
+[source,terminal]
+----
+$ oc get controlplanemachinesets.machine.openshift.io -n openshift-machine-api
+----
+
+. Create new `MachineSet` CRs for your failure domains.

+----
+$ oc get machinesets.machine.openshift.io -n openshift-machine-api <existing_machine_set> -o yaml > machineset-<failure_domain_name>.yaml
+----
++
