{product-title} is capable of provisioning persistent volumes (PVs) using the Container Storage Interface (CSI) driver for Microsoft Azure Disk Storage.
Familiarity with persistent storage and configuring CSI volumes is recommended when working with a CSI Operator and driver.
To create CSI-provisioned PVs that mount to Azure Disk storage assets, {product-title} installs the Azure Disk CSI Driver Operator and the Azure Disk CSI driver by default in the openshift-cluster-csi-drivers namespace.
-
The Azure Disk CSI Driver Operator provides a storage class named
managed-csithat you can use to create persistent volume claims (PVCs). The Azure Disk CSI Driver Operator supports dynamic volume provisioning by allowing storage volumes to be created on-demand, eliminating the need for cluster administrators to pre-provision storage. You can disable this default storage class if desired (see Managing the default storage class). -
The Azure Disk CSI driver enables you to create and mount Azure Disk PVs.

{product-title} provides automatic migration for the Azure Disk in-tree volume plugin to its equivalent CSI driver. For more information, see CSI automatic migration. |

Note
|
If the OS (root) disk is encrypted, and there is no encrypted key defined in the storage class, Azure Disk CSI driver uses the OS disk encryption key by default to encrypt provisioned storage volumes. |
