NOTE: The vol snapmirror on command does not persist across filer
reboots. Put the command in the /etc/rc file if you want the command to remain
in effect after the filer is rebooted. If the /etc/rc file does not contain a vol
snapmirror command, data replication is disabled.
4. If the source volume and the mirror reside on different filers, and if the source
volume has quotas enabled, copy the /etc/quotas file from the source filer to a
file on the destination filer. Whenever you make a change to the /etc/quotas file
on the source filer, make the same change to the copy on the destination filer so
that the destination filer always contains a record of all the quota entries used by
the source filer.

You can disable data replication for the entire filer if you decide that data replication is
no longer necessary. You can disable the feature at any time, even when replication is
underway. The mirror remains unchanged after you disable replication.

Follow these steps to disable volume replication for the entire filer:
1. Enter the vol snapmirror off command on the destination filer to disable
SnapMirror.
Result: If the filer is currently transferring data from one volume to another, the
transfer stops immediately. The destination volume remains the same as before
the transfer. The snapshot taken in the source volume for the data transfer
remains, but is deleted and replaced by a new snapshot the next time the mirror
is updated.
The filer stops reading the /etc/snapmirror.conf file every minute.
Entering the vol snapmirror off command on the destination filer does not
affect SnapMirror on the source filer. Other filers can continue to replicate data
from the source filer.
2. If the vol snapmirror on command is in the /etc/rc file, remove the
command.
NOTE: There is no need to enter the vol snapmirror off command in the
/etc/rc file. By default, data replication is disabled.
