Setting Up the Systems for Bidirectional Remote Copy

In bidirectional Remote Copy, the backup system (for example, System2) also contains primary

volume groups and therefore is also considered a primary system for the purposes of the primary

volume groups it contains.

Verify that unidirectional 1-to-1 Remote Copy is already set up.

• If a unidirectional 1-to-1 configuration is already set up, proceed to “Creating Volume Groups

for Bidirectional Remote Copy” (page 78).

If unidirectional 1-to-1 Remote Copy is set up, the required links between the Remote Copy

systems already exist. To create a bidirectional configuration, you only need to create primary
