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

Displaying detailed information about

journal groups
