When the copy pair configuration is complex
For a complex configuration, such as one in which a copy group has two primary volumes, copy
group configuration information cannot be displayed when copy groups are displayed in list format,
as they are in the pair configurations view.
The following are specific examples:
When two configuration definition files defining an opposite relationship of primary and secondary
volumes are used for one copy group
To view an illustration, see Example of complex cascade configuration 1 on page 444.
In a cascade configuration consisting of a primary volume, primary-secondary volume, and sec-
ondary volume, the primary volume and secondary volume are paired in the same copy group
(the two pair relationships are defined in the same copy group).
To view an illustration, see Example of complex cascade configuration 2 on page 445.
Example of complex cascade configuration 1
The following figure shows an example of this configuration. Configuration definition file A defines
copy group A as the primary volume and copy group B as the secondary volume. On the other hand,
configuration definition file B defines copy group B as the primary volume and copy group A as the
secondary volume.
Example when two configuration files define an opposite relationship of primary and secondary volumes for the
same copy group
