Breaking a SnapMirror relationship from the Volume Relationships page
You can break a protection relationship to stop data transfers between a source volume and a destination volume in a SnapMirror relationship. You might break a relationship when you want to migrate data, for disaster recovery, or for application testing. The destination volume is changed to a read/write volume. You cannot break a SnapVault relationship.
What you’ll need
You must have the Application Administrator or Storage Administrator role.
You must have set up Workflow Automation.
From the Volume Relationships page, select one or more volumes with protection relationships for which you want to stop data transfers and, on the toolbar, click Break.
The Break Relationship dialog box is displayed.
Click Continue to break the relationship.
In the Volume Relationships page, verify in the Relationship State column that the relationship is broken.
