You can check the status of Advanced Copy in "Copy Control", the "Status" field of each copy type or the "Phase" field.
Note
If "???" or "Unknown" is displayed in the "Status" or "Phase" field, it is possible that an access path is wrong. Check the access path with "D.1.4 acarray detail (Command for displaying detailed information about ETERNUS Disk storage systems)".
If the access path is wrong, see the "6.4.1.1 Access Path Settings" to set a proper access path.
