 = Customizing the storage profile
 
-You can customize any storage profile. Use the `spec` section of the storage profile to provide specific attributes when creating an underlying persistent volume claim (PVC) for a data volume.
+You can specify default parameters by editing the `StorageProfile` object for the provisioner's storage class. These default parameters only apply to the persistent volume claim (PVC) if they are not configured in the `DataVolume` object.
+
+.Prerequisites
+* Ensure that your planned configuration is supported by the storage class and its provider. Specifying an incompatible configuration in a storage profile causes volume provisioning to fail.
