Continentalclusters Version A.07.00 Release Notes
What’s In This Version
Chapter 18
NOTE The maintenance mode is an optional feature. To enable the
maintenance mode, configure a shared disk (non-replicated) with a file
system on all recovery clusters and the Continentalclusters
configuration file must be specified using the
CONTINENTAL_CLUSTER_STATE_DIR parameter.
For more information on using this command in your environment, see
the Designing Disaster Tolerant HA Clusters using Metrocluster and
Continentalclusters document.
Support for Disaster Recovery Rehearsal Operations
The DR rehearsal feature of Continentalclusters rehearses 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.
For DR Rehearsal, Continentalclusters is enhanced to allow recovery
groups to be configured with a special rehearsal package which is
specified as part of the recovery group definition. The DR Rehearsal
process starts the rehearsal package which has a package configuration
that is similar to that of the recovery package and thereby verifies the
recovery environment and the recovery procedure. The cmrecovercl
command is enhanced to provide option {-r -g <recovery group>}to
rehearse recovery for a specified recovery group on the recovery cluster.
IMPORTANT For disaster recovery rehearsal, the recovery group must be in the
maintenance mode.
For more information on how to set up and run DR rehearsal in your
environment, see the Designing Disaster Tolerant HA Clusters using
Metrocluster and Continentalclusters document.
