Transferring Business Tasks from the XP Continuous Access Secondary Site to the Primary Site (in
a 3DC Multi-target Configuration)
If you remove failures from the primary site and other locations, and then the system is changed
to a 3DC multi-target configuration (see
“Recovering from Primary Site Disaster in a 3DC Multi-Target
and
“Changing to a 3DC Multi-Target Configuration After Recovering
from Primary Site Failures” (page 93)
), you can transfer your business tasks back to the primary
site.
To transfer your business tasks back to the primary site, follow the procedure described in this
section. RAID Manager is used in this procedure.
1.
Use RAID Manager to release the current XP Continuous Access Journal pair, which extends
between the XP Continuous Access secondary site and the XP Continuous Access Journal
secondary site.
2.
Stop the business tasks at the XP Continuous Access Synchronous secondary site.
3.
Use RAID Manager to execute the horctakeover command on the XP Continuous Access
Synchronous pair.
4.
Use the primary volume at the primary site to resume your business tasks.
5.
Use RAID Manager to create an XP Continuous Access Journal pair. Ensure that the XP
Continuous Access Journal primary data volume is a volume at the primary site, and that the
XP Continuous Access Journal secondary data volume is a volume at the XP Continuous Access
Journal secondary site.
The system configuration returns to the original 3DC multi-target configuration.
