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.

For more information about using XP RAID Manager, see the HP StorageWorks XP RAID Manager

user guide.

For more information about status of data volumes, see XP Continuous Access Journal data volume

pair status.
