If data is being copied between two storage systems, you can stop copying by executing the vol copy abort command on either storage system. If you start the volume copying operation from the system console, you can enter the vol copy abort command only through the rsh command. This is because you do not have access to the system prompt on the console during the copying.
To stop a specific volume copy operation, you need to specify the operation number. You can obtain the operation number from the vol copy status output.
