Transferring Business Tasks from the XP Continuous Access Journal Secondary Site to the Primary
Site
If you follow the instructions in
“Recovering from Failures at the Primary Site and the XP Continuous
Access Synchronous Secondary Site” (page 98)
, and then remove failures from the primary site
and the XP Continuous Access Synchronous secondary site, you can transfer your business tasks
back to the primary site.
To transfer your business tasks back to the primary site, follow the described in this section. RAID
Manager is used in this procedure.
1.
Use RAID Manager to release the XP Continuous Access Synchronous pair.
2.
If the XP Continuous Access Journal pair has not been resynchronized to reverse the primary
volume and the secondary volume and is suspended, use RAID Manager to resynchronize the
pair to reverse the primary and secondary volumes.
The secondary data volume at the former XP Continuous Access Journal secondary site changes
to the primary data volume. The primary data volume at the former primary site changes to
the secondary data volume (see the upper-right picture in
).
3.
Stop the business tasks at the XP Continuous Access Journal secondary site.
4.
Use RAID Manager to execute the horctakeover command on the XP Continuous Access
Journal pair.
The XP Continuous Access Journal primary and secondary volumes are reversed.

Use the primary volume at the primary site to resume the business tasks.
6.
Use RAID Manager to resynchronize the XP Continuous Access pair.
The system configuration changes to the original 3DC multi-target configuration (see the
