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.
