Create FlashCopy relationship — Define relationship types

Use this page to define the type of FlashCopy^® relationship that you want to create.

Introduction

This page allows you to define the type of FlashCopy relationship that you want to create: either a 1:1 FlashCopy relationship (a single source volume and a single target volume) or a 1:n multiple FlashCopy relationship (a single source volume and multiple target volumes). The relationships must all be of the same type.

The type of FlashCopy relationships that you want to create for your source and target volumes. You must select one of the following options as a prerequisite for creating FlashCopy relationships. You cannot select both. If you select either option, the other option is automatically not selected.

A single source with a single target: A FlashCopy relationship that consists of a volume pair: a single source volume and a single target volume. This is the default selection.
A single source with multiple targets: A FlashCopy relationship that consists of a source volume with multiple target volumes (also known as multiple relationship FlashCopy). Choose this option if you want to create more than one point-in-time copy of the source volume. For example, you might want to use one target volume for testing and have another target volume that remains unchanged for comparison.
