Access XP Journal terminology is now reversed: the original primary data volumes are now secondary
data volumes, and the original secondary data volumes are now primary data volumes.
1.
At the primary and secondary sites, ensure that all Continuous Access XP Journal components
are fully operational and are free from failures.
2.
Ensure that pair status of primary and secondary data volumes in all Continuous Access XP Journal
pairs is PAIR. This indicates that the Continuous Access XP 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 RAID Manager XP 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
