134 Performing Continuous Access XP Journal pair operations
Creating a Point-in-Time copy of data volumes
Use Continuous Access XP Journal to make Point-in-Time (PiT) duplicates of groups of volumes. The term
Point-in-Time (PiT) refers to the process of copying data immediately when you want to obtain it. Use
Continuous Access XP Journal to create a PiT copy of data volumes belonging to a journal group.
1. Stop all write I/Os from hosts to primary data volumes in the journal group. Stop all host updates to all
Continuous Access XP Journal primary data volumes in the group.
2. After all write I/Os to primary data volumes are stopped, split the mirror (that is, a pair of the master
and restore journal groups, see ” Splitting mirrors (Pairsplit-r: suspending copy operations) ” on
page 111). When splitting the mirrors, use the Pairsplit-r pane, specify Group for Range, and specify
Flush for Suspend Mode.
3. When the status of all data volume pairs in the journal group changes to PSUS, the duplicate set of
volumes is complete. If desired, restart your business application at the primary site to resume business
activities.
