 **Tip:** If `VolumeSnapshots` are needed, follow the guidance in HPE CSI Driver documentation on how to [enable CSI snapshots](https://scod.hpedev.io/csi_driver/using.html#enabling_csi_snapshots) and [how to use them](https://scod.hpedev.io/csi_driver/using.html#using_csi_snapshots).

 ## CHAP support
 
 From v2.5.1 onwards iSCSI CHAP is supported. Follow the [guidance provided by HPE](https://scod.hpedev.io/csi_driver/index.html#iscsi_chap_considerations). Retrofitting CHAP into an existing cluster is not recommended. Bi-directional CHAP is not supported by the HPE CSI Driver and will not work with the TrueNAS CSP.
