A disaster causes a FlexGroup volume to be unrecoverable, but it was protected by a SnapMirror relationship. You solve the issue, and the source is operational.
Now, you want to return to serving the data from the original source.
In this scenario, what do you do next?
When you want to return to serving data from the original source after a disaster, you need to remove the existing SnapMirror relationship to ensure that the source is no longer dependent on the backup destination. Therefore, the correct step would be to delete the SnapMirror relationship.

This is down to wording , trys to trip you up with whether its an "Initialization" or a "Deletion" of the SnapMirror relationship, AS above comment, you are deleting the SnapMirror relationship betweeen src & dst , then resynching .Not Inializng,
