Continentalclusters Version A.08.00 Release Notes, March 2013

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)
• Metrocluster with Continuous Access for P9000 and XP A.11.00 April 2011 patches
(PHSS_41663 on 11i v2 and PHSS_41664 on 11i v3)
• Metrocluster Data Replication Enabler Toolkit A.10.00 April 2011 patches (PHSS_41655 on
11i v2 and PHSS_41656 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.

Support for Disaster Recovery Rehearsal Operations in a 3DC DR Solution
With the introduction of the following patches, the DR rehearsal feature of Continentalclusters 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)
• Metrocluster with Continuous Access for P9000 and XP A.11.00 April 2011 patches
(PHSS_41663 on 11i v2 and PHSS_41664 on 11i v3)
• Metrocluster Data Replication Enabler Toolkit A.10.00 April 2011 patches (PHSS_41655 on
11i v2 and PHSS_41656 on 11i v3)
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 Designing Disaster
Recovery HA Clusters Using Metrocluster and Continentalclusters, April 2011 (5900-1484) available
at http://www.hp.com/go/hpux-serviceguard-docs —> HP Serviceguard.
NOTE: The DR rehearsal feature is not supported in a 3DC environment when the complex
workloads are configured using Site Aware Disaster Tolerant Architecture (SADTA).
