Figure 33 Recovering from primary site disasters (when performing delta resync

operations)

Changing back to a 3DC multi-target conﬁgurations after recovering from primary site failures

If you follow the instructions in Recovering from primary site failures and the system does not change to a

3DC cascading conﬁguration due to primary site failures, you have the ability to change the system to

a3DCmulti-targetconﬁguration after removing failures from the primary site and other locations. In

the resulting 3DC multi-target conﬁguration, the former Continuous Access XP secondary volume is the

multi-target primary volume.

To change the system to a 3DC multi-target conﬁguration:

1. Use RAID Manager XP to delete the former (data center 1 to data center 3) Continuous Access

XP Journal pair.

2. If a pair resynchronization has not been performed to reverse the Continuous Access XP Synchronous

pair's primary/secondary relationship (that is, if the pair is suspended), use RAID Manager XP to

resynchronize the pair, so the primary/secondary relationship is reversed from its original direction

(the DC2 to DC3 Journal pair is still intact).
