Viewing storage volume details for your DB instance

You can view your storage volume configuration from the Amazon Management Console or Amazon CLI. This includes details about both your primary storage volume and any additional storage volumes attached to your DB instance.

The StorageVolumeStatus field indicates whether the volume is currently in use by your database. A status of Not-in-use means the volume is attached but it's not in use by the database engine or an RDS feature.
