CAUTION:
After you remove failures from the primary site and other locations and then the system
is changed to 3DC multi-target configuration (see Requirements for creating Continuous
Access XP Journal pairs for delta resync operations ), the status of a pair between the
primary site and the Continuous Access XP Journal secondary site may be abnormal. If
the status of the pair remains abnormal, you will be unable to transfer your business tasks
back to the primary site. To solve this problem, check the pair status and then perform a
problem-solving operation before transferring business tasks back to the primary site.
