+As a preview feature, you can configure Azure Container Storage to use Azure Elastic SAN. This article covers how to make that configuration. At the end of this article, you'll have a pod that's using Elastic SAN as its storage.
 
 ## Prerequisites
 
 [!INCLUDE [container-storage-prerequisites](../../../includes/container-storage-prerequisites.md)]
 
-- Ensure you have either an [Azure Container Storage Owner](../../role-based-access-control/built-in-roles/containers.md#azure-container-storage-owner) role or [Azure Container Storage Contributor](../../role-based-access-control/built-in-roles/containers.md#azure-container-storage-contributor) role on your subscription. Either of these roles will grant permissions that allow Azure Container Storage to communicate with the Elastic SAN resource. To make this change, go to your subscription page on the Azure portal. Select **Access control (IAM) > Add role assignment** and search for either "Azure Container Storage Owner" or "Azure Container Storage Contributor" in the **Job function roles** tab. Select **View > Assignments > Add assignment** and add your account.

 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](#2-display-the-available-storage-classes).
