Modify SnapMirror workflow

Goal

The Modify SnapMirror workflow changes the current attributes in a SnapMirror or SnapVault relationship, including the maximum transfer rate, SnapMirror policy, and SnapMirror schedule, so that you can increase or decrease bandwidth used for transfers, or change when and how often updates occur depending on how frequently data is updated.

Prerequisite

         You must be running Clustered Data ONTAP 8.2 or later.

About this workflow

The Modify SnapMirror workflow changes one or more parameters of a SnapMirror or SnapVault relationship. The SnapMirror or SnapVault relationship is identified by its destination cluster, Storage Virtual Machines, and volumes and these must be specified as the command input parameters.

Keep the following considerations in mind when using the Modify SnapMirror workflow:

         Changes made by the Modify SnapMirror workflow do not take effect until the next manual or scheduled update of the relationship.

         Changes do not affect updates that have started and have not yet finished.

         The Modify SnapMirror workflow is not supported on Infinite Volume constituents.
