Support for Data Replication Storage Failover Preview in a 3DC DR Solution
With the introduction of the following patches, the cmdrprev command is supported in
a 3DC DR Solution:
• Continentalclusters A.08.00 April 2011 patches (PHSS_41657 on 11i v2 and
PHSS_41658 on 11i v3)

The cmdrprev command enables you to preview the preparation process for data
replication in a Three Data Center environment. This command also enables you to
identify potential problems in the data replication environment that, if left undetected,
can result in an unsuccessful Metrocluster failover or Continentalclusters recovery scenario.
This feature is supported on Serviceguard versions A.11.19 and A.11.20. This feature
does not require Serviceguard A.11.20 April 2011 patch PHSS_41628.

The DR rehearsal feature allows you to rehearse recovery for a recovery group without
impacting the availability of the primary package. The DR Rehearsal feature helps detect
configuration discrepancies at the recovery cluster and ensures that the recovery cluster
is prepared to handle a disaster recovery scenario.
To configure and perform disaster recovery rehearsal in a 3DC environment, see
