= Enabling dynamically-provisioned storage

Instead of statically-provisioned storage, you can use dynamically-provisioned storage.

.Procedure

. To enable dynamic storage for Prometheus and Alertmanager, set the following parameters to `true` in the Ansible inventory file:
+
* `openshift_cluster_monitoring_operator_prometheus_storage_enabled`   (Default: false)
* `openshift_cluster_monitoring_operator_alertmanager_storage_enabled` (Default: false)
+
. Optional: After you enable dynamic storage, you can also set the `storageclass` for the persistent volume claim for each component in the following parameters in the Ansible inventory file:
+
* `openshift_cluster_monitoring_operator_prometheus_storage_class_name`   (default: "")
* `openshift_cluster_monitoring_operator_alertmanager_storage_class_name` (default: "")
+
Each of these variables applies only if its corresponding `storage_enabled` variable is set to `true`.
