snapmirror.conf - configuration file specifying how filers replicate
volumes using SnapMirror
/etc/snapmirror.conf
The /etc/snapmirror.conf file exists on the filer containing the mirror
used for SnapMirror. Each entry of the file specifies the volume to be
replicated, an argument for the replication, and the schedule for updating
the mirror.
Each entry of the /etc/snapmirror.conf file is in this format:
source_filer:source_vol destination_filer:destination_vol argument schedule
The following list describes the fields in each entry:
- source_filer
- the name of the filer containing the source volume.
- source_vol
- the name of the source volume.
destination_filer the name of the filer containing the mirror.
destination_vol the name of the mirror.
- argument
- the maximum speed at which data is transferred, which is
specified in kbs (kilobytes per second). Enter a value
greater than or equal to 11. By default, the filer
transfers the data as fast as it can. To accept the
default, specify a dash.
- schedule
- the schedule used by the destination filer for updating
the mirror. The schedule contains four fields: minute,
hour, day of month, and day of week. The fields are
separated from each other by a space. If a field contains
more than one value, the values are separated from each
other by a comma. A field containing an asterisk means
that the field is irrelevant.
The following snapmirror.conf entry copies /vol/vol1 on filerA to /vol/vol2
on filerB at a maximum rate of 2,000 kilobytes per second. FilerB updates
the mirror at 10:45 a.m., 11:45 a.m., 12:45 p.m., 1:45 p.m., 2:45 p.m.,
3:45 p.m., and 4:45 p.m., Monday through Friday. The asterisk means that
the data replication schedule is not affected by the day of month.
