2. Ensure that pair status of primary and secondary data volumes in all XP Continuous Access
Journal pairs is PAIR. This indicates that the XP Continuous Access Journal initial copy operations
are complete and consistency is maintained.
3. Stop the applications at the secondary site.
4. Issue a request for splitting pairs to master journal groups (which were originally restore journal
groups); use the Flush option when splitting pairs. If an error occurs when splitting pairs,
remove the error cause and go back to step 1 after resuming your business task at the
secondary site.
5. If no error occurs in step 4, wait until suspension finishes. After suspension finishes, check
whether there is a secondary data volume (which was originally a primary data volume) whose
pair status is other than PSUS. If such a pair exists, remove the error cause and go back to
step 1 after resuming your business task at the secondary site.
6. If there is no secondary data volume (which was originally a primary data volume) whose
pair status is other than PSUS, data in primary data volumes is the same as data in secondary
data volumes, and the secondary data volume (which was originally primary data volume) is
usable. Resume applications at the primary site.
7. Execute the pairresync -swaps command ( pairresync is the XP RAID Manager command
for resynchronizing pair and -swaps is a swap option). This reverses primary and secondary
data volumes to resynchronize pairs.
CAUTION: When executing the pairresync -swaps command, use the -d option to
specify a data volume. However, if the restore journal group where the data volume belongs
is in Active, Halting, or Stopping status, the
pairresync -swaps command is rejected. For
more information about journal group status, see Displaying detailed information about journal
groups .

user guide.
