Notes:
• Make sure that you do not access the external volume, which has
been mapped as a internal volume, from the host that is connected to
the external storage system. Also make sure that you do not access
the mapped external volume using the function (e.g., copy function)
of the external storage system. Once you have mapped an external
volume as an internal volume, you can access the mapped external
volume only from the local storage system side.
• From the host, you can access the external storage system volumes
that have not been mapped as the internal volumes. There is no
restriction.
