Transferring business tasks from Continuous Access XP secondary sites to primary sites (in 3DC
multi-target configurations)
If you remove failures from the primary site and other locations and the system changes to a 3DC
multi-target configuration (see” Recovering from primary site failures ” on page 70 and ” Changing to 3DC
multi-target configurations after recovering from primary site failures ” on page 71), you can transfer your
business tasks back to the primary site.
To transfer your business tasks back to the primary site:
1. Use RAID Manager XP to delete the current Continuous Access XP Journal pair, which extends
between the Continuous Access XP secondary site and Continuous Access XP Journal secondary site.
2. Stop your business tasks at the Continuous Access XP Synchronous secondary site.
3. Use RAID Manager XP to execute the
horctakeover
command on the Continuous Access XP
Synchronous pair.
4. Use the primary volume at the primary site to resume your business tasks.
5. Use RAID Manager XP to create a Continuous Access XP Journal pair. Ensure that the Continuous
Access XP Journal primary data volume is a volume at the primary site, and the Continuous Access XP
Journal secondary data volume is a volume at the Continuous Access XP Journal secondary site. The
system configuration returns to the original 3DC multi-target configuration.

Recovering from primary site and Continuous Access XP Synchronous secondary site failures
If a disaster or failure occurs in the primary site and Continuous Access XP Synchronous secondary site in
a 3DC multi-target configuration, you can resume your business tasks using the secondary volume in the
Continuous Access XP Journal secondary site. After transferring your business tasks to the Continuous
Access XP Journal secondary site, remove failures from the primary site and Continuous Access XP
Synchronous secondary site, and transfer your business tasks back to the primary site.
To transfer your business tasks to the Continuous Access XP Journal secondary site:
1. Use RAID Manager XP to execute the
horctakeover
command on the Continuous Access XP Journal
pair.
