Ensure that you have the necessary privileges on the catalog, schema, and volume, to access a volume, you must have the USE CATALOG privilege on the Volume’s parent catalog and the USE SCHEMA privilege on its parent schema.

If you're trying to create a volume, you need the CREATE VOLUME privilege on the schema where you want to create the Volume, the USE SCHEMA privilege on the schema, and the USE CATALOG privilege on the parent catalog.

If you're dealing with an External Volume, you must also have the CREATE EXTERNAL VOLUME privilege on an External Location where you want to create the Volume.
