Continuous Access XP Journal user guide 45
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.
