 First, create a storage pool, which is a logical grouping of storage for your Kubernetes cluster, by defining it in a YAML manifest file.
 
+If you enabled Azure Container Storage using `az aks create` or `az aks update` commands, you might already have a storage pool. Use `kubectl get sp -n acstor` to get the list of storage pools. If you have a storage pool already available that you want to use, you can skip this section and proceed to [Display the available storage classes](#display-the-available-storage-classes).

 > [!IMPORTANT]
 > If you want to use your own keys to encrypt your volumes instead of using Microsoft-managed keys, don't create your storage pool using the steps in this section. Instead, go to [Enable server-side encryption with customer-managed keys](#enable-server-side-encryption-with-customer-managed-keys) and follow the steps there.
