The /etc/snapmirror.conf file resides on the destination filer. It controls where data is
copied and how often a mirror is updated.
The filer is not shipped with a default /etc/snapmirror.conf file. You must use a text
editor to create the file if you want to use SnapMirror.

Each entry of the /etc/snapmirror.conf file is in the following format:
source_filer:source_vol destination_filer:destination_vol argument schedule

The following list describes the meaning of each field in a snapmirror.conf entry:
source_filer is the host name of the filer from which data is replicated.
source_vol is the source volume name. For example, for the vol1 volume, type
vol1. Do not type the full path name (/vol/vol1).
destination_filer is the host name of the filer to which data is replicated.
destination_vol is the destination volume (mirror) name. For example, for the vol1
volume, type vol1. Do not type the full path name (/vol/vol1).
argument is kbs (kilobytes per second), the maximum speed at which data is
transferred. Enter a value greater than or equal to 11. By default, the filer transfers
the data as fast as it can. Enter a dash (-) to indicate that you want to use the
default value for argument.
NOTE: The actual data transfer speed might be limited by factors such as network
bandwidth. For example, if you specify a large value such as 1,000,000, the filer might
still transfer the data at 2,000 kilobytes per second.
schedule is the schedule used by the destination filer for updating the mirror.
You must not leave any field in a snapmirror.conf entry blank. If you do not want to
specify the maximum speed for data transfer, specify a dash as the
argument.
