Caution on transferring business tasks back to the primary site when using delta resync:
•
If both pair status in primary and secondary site is Hold, the pair is in normal condition. So,
you can transfer business tasks to the primary site as described earlier in this section.
•
After you remove failures from the primary site and other locations, if the system is changed
to 3DC multi-target configuration, the status of a pair between the primary site and the Universal
Replicator for Mainframe 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, follow the next steps:
◦ In following table, check the pair status.
◦ Perform a problem-solving operation and change the pair status to normal status.
◦ Transfer business tasks back to the primary site.
