Access XP Journal pair's secondary data volume must be the secondary data volume at the
Continuous Access XP Journal secondary site.
b. If the Continuous Access XP Synchronous pair's primary/secondary relationship is reversed
(that is, the copy direction is reversed as illustrated in the lower-right portion of Figure 32 (
because the primary site is no longer operational), re-create the Continuous Access XP Journal
pair deleted in step 1 via full copy. When you finish re-creating the Continuous Access XP
Journal pair, the system configuration changes from a 3DC multi-target configuration to a 3DC
cascading configuration, and the former Continuous Access XP Synchronous secondary volume
changes to the primary volume.
NOTE:
•
If you followed step 4a, transfer your business tasks back to the primary site by removing failures
in the primary site and other locations, changing the system to a 3DC multi-target configuration
(see Changing to 3DC multi-target configurations after recovering from primary site failures ), and
following the instructions in Transferring business tasks from Continuous Access XP secondary sites to
primary sites (in 3DC multi-target configurations) .
• If you followed Step 4b, transfer your business tasks back to the primary site by removing failures in
the primary site and other locations, and following the instructions in Transferring business tasks from
Continuous Access XP secondary sites to primary sites (in 3DC cascading configurations) .
