and you use the CL1-A port as an RCU target port in the Continuous Access XP Journal primary site, you
must not use the CL1-A or CL5-A port as an RCU target port in the Continuous Access XP secondary
site. As these examples indicate, you must avoid using illegal combinations of an RCU target port in the
Continuous Access XP Journal primary site and a target port in the Continuous Access XP Journal primary
site. Also, when configuring a system in a 3DC cascading configuration, you must avoid using illegal
combinations of an RCU target port in the Continuous Access XP Journal primary site and an RCU target
port in the Continuous Access XP secondary site.
If you use illegal port combinations, Continuous Access XP Journal remote copy operations are likely to
be suspended due to failures. If a Continuous Access XP Journal remote copy operation is suspended due
to a failure, the following problems occur and the remote copy operation cannot be performed:
•
The primary array cannot read data from the primary data volume.
•
In a system with a 3DC cascading configuration, the intermediate site cannot read data from a
volume used as both a Continuous Access XP Synchronous secondary volume and a Continuous
Access XP Journal primary data volume.
