Follow these steps to disable data replication for one volume. These steps disable vol-
ume replication until you reenable it.
1. Comment out the entry in the
/etc/snapmirror.conf
file by preceding the entry
with a pound sign (#).
2. Enter the
vol snapmirror on
command to make the filer reread the
/etc/
snapmirror.conf
file.
Result: If the filer is currently transferring data from that volume, the transfer
stops immediately.

Follow these steps to disable data replication while data transfer is in progress. These
steps stop the replication temporarily; at the time of the next scheduled update, data
replication starts up again.
1. Enter the
vol copy status
command to display the operation numbers of the
volume copy.
Result: Because SnapMirror uses the
vol copy
command to transfer data, the
vol copy status
command displays all volume copy operations, including the
one for replicating a volume.
2. Enter the
vol copy abort
command to terminate the volume copy operation.
Result: The filer stops copying data and displays messages similar to these:

If you want to know how much data has been copied to the mirror or whether a filer is
using resources for replicating data, you can use the
vol snapmirror status
command at any time to check the status of data replication.

SnapMirror must be enabled before you can check the status of data replication.
Otherwise, the following error message is displayed:
Snapmirror is turned off.
