Creating a SnapMirror policy to maximize transfer efficiency

You can create a SnapMirror policy to specify the SnapMirror transfer priority for protection relationships. SnapMirror policies enable you to maximize transfer efficiency from the source to the destination by assigning priorities so that lower-priority transfers are scheduled to run after normal-priority transfers.

1. From the SnapMirror tab of the Configure Protection dialog box, click the Create Policy link in the Relationship Settings area.
   The Create SnapMirror Policy dialog box is displayed.
2. In the Policy Name field, type a name you want to give the policy.
3. In the Transfer Priority field, select the transfer priority you want to assign to the policy.
4. In the Comment field, enter an optional comment for the policy.
5. Click Create.
   The new policy is displayed in the SnapMirror Policy drop-down list.
