+= Configuring {lvms} using PolicyGenTemplate CRs
+
+You can configure {lvms-first} for managed clusters that you deploy with {ztp-first}.
+
+[NOTE]
+====
+You use {lvms} to persist event subscriptions when you use PTP events or bare-metal hardware events with HTTP transport.
+====
+
+.Prerequisites
+
+* Install the OpenShift CLI (`oc`).
+
+* Log in as a user with `cluster-admin` privileges.
+
+* Create a Git repository where you manage your custom site configuration data.
+
+.Procedure
+
+. To configure {lvms} for new managed clusters, add the following YAML to `spec.sourceFiles` in the `common-ranGen.yaml` file:
++
+[source,yaml,subs="attributes+"]
+----
+- fileName: StorageLVMOSubscriptionNS.yaml
+  policyName: subscription-policies
+- fileName: StorageLVMOSubscriptionOperGroup.yaml
+  policyName: subscription-policies
+- fileName: StorageLVMOSubscription.yaml
+  spec:
+    name: lvms-operator
+    channel: stable-{product-version}
+  policyName: subscription-policies
+----
+
+. Add the `LVMCluster` CR to `spec.sourceFiles` in your specific group or individual site configuration file. For example, in the `group-du-sno-ranGen.yaml` file, add the following:
++
+[source,yaml]
+----
+- fileName: StorageLVMCluster.yaml
+  policyName: "lvmo-config" <1>
+  spec:
+    storage:
+      deviceClasses:
+      - name: vg1
+        thinPoolConfig:
+          name: thin-pool-1
+          sizePercent: 90
+          overprovisionRatio: 10
+----
+<1> This example configuration creates a volume group (`vg1`) with all the available devices, except the disk where {product-title} is installed.
+A thin-pool logical volume is also created.
+
+. Merge any other required changes and files with your custom site repository.
+
+. Commit the `PolicyGenTemplate` changes in Git, and then push the changes to your site configuration repository to deploy {lvms} to new sites using {ztp}.
