Limitations of DR rehearsal feature
Following are the limitations of the DR rehearsal feature:
1. The replication, preparation, and restoration for rehearsal and restoration for recovery is
manual. The operator must prepare and restore the replication environment for every recovery
group.
2. The cmdrprev preview command currently supports only verbose output.
3. Since the replication between the primary and recovery cluster is suspended during rehearsal,
the production changes to the primary mirror copy must not be replicated to the recovery
cluster. Hence, in the case of a disaster and subsequent recovery of primary cluster during
rehearsal, the production changes since the start of rehearsal is lost. Therefore, to minimize
the “potential” data loss, HP recommends that you adjust the DR rehearsal time window to
be less than the recovery point object.
