To stop a volume copy operation, use the following command syntax:
vol copy abort [
operation_number
]
The
operation_number
parameter specifies the volume copy operation to be aborted.
You can obtain the operation number from the
vol copy status
output.

If data is being copied between two filers, you can execute this command on either
filer.
If you start the volume copying operation from the filer console, you can enter the
vol copy abort
command only through
rsh
because you do not have access to
the filer prompt on the console during the copying.

You can control the speed of a volume copy operation in two ways.
Before you enter the
vol copy start
command, use the following com-
mand syntax to set the default speed for all volume copy operations:
options vol.copy.throttle
value
The
value
variable specifies the speed, which ranges from 10 (full
speed) to 1 (one-tenth of full speed).
If a volume copy operation is in progress, use the following command syntax to
set the speed of a specific operation:
vol copy throttle [
operation_number
]
value
In this case, because a volume copy operation is in progress and you do not have
access to the filer prompt, you must enter the
vol copy throttle
com-
mand through
rsh
.
The
operation_number
parameter specifies the volume copy operation whose
speed you want to adjust. If you do not specify an operation number, the com-
mand applies to all volume copy operations that are in progress. The
value
variable specifies the speed, which ranges from 10 (full speed) to 1 (one-tenth of
full speed).
NOTE: The speed for reading data from the source volume and the speed for writing
data to the destination volume can be different. In this case, the smaller of the two
values determines the time required for the filer to finish copying the data.
