4. Create pair groups and associate them with the previously added copy groups. When applying
the association, specify a consistency group ID or journal group ID.
If the storage system and volume selected for the second copy pair configuration are the same
as the storage system and volume selected for the initial copy pair configuration, specify a different
CTGID/JNLGID from the CTGID/JNLGID specified first.

Supported copy group and container combinations
In the following discussion, the term target group refers to the initial copy group or container in a
cascade configuration (cascade source group). The term following group refers to the subsequent
copy group or container cascaded with the initial copy group or container (cascade destination
group).
The following are supported combinations of copy groups and containers when defining cascade
configurations:
• If the target group is a local copy group, it can only be combined with a following group that is
a remote copy group.
• If the target group is a local copy group container, it can be combined with a following group
that is a remote copy group container.
• If the target group is a remote copy group, it can be combined with a following group that is a
local copy group or a remote copy group.
• If the target group is a remote copy group container, it can be combined with a following group
that is a local copy group container or a remote copy group container. In addition, the target remote
copy group container can also be combined with a following group that is a local copy group.

About multi target and cascade copy pair configurations
Using the Pair Configuration Wizard you can define multi-target or cascade configurations that consist
of multiple copy pairs and copy groups, in a single sequence of operations. The following are sample
multi-target and cascade configurations:
