About SnapMirror configuration

The SnapMirror Configuration page enables you to configure the SnapMirror for the license code and to enable IP checking.

Prerequisites

The following prerequisites must be met before you can replicate a volume or qtree:

• You must purchase the SnapMirror license. If the source and the mirror are on different filers, you must purchase a license and enter the SnapMirror license code for each filer using the license command on the command line.

• You must create an offline volume to be used as the mirror. SnapMirror does not automatically create a volume.

• The source volume and the mirror volume must be of the same volume type. For example, if the source is a traditional volume, the volume you create to be its mirror must be another traditional volume.

• The source volume must be online.

• If the source is a qtree, it must not be a mirror.

• The capacity of the mirror must be greater than or equal to the capacity of the source volume. The configuration of the volumes, however, can be different.

• The mirror must not be the root volume.
