What’s In this Version
Continentalclusters employs semi-automatic failover of Serviceguard
packages from one cluster to another following a cluster event that
indicates serious disruption of service on one of the clusters. The product
consists of a set of configuration, management commands, and a set of
daemons that monitors and sends notification of cluster events.
The A.06.00 version includes the following enhancement:
• Recovery of application packages configured with Veritas Cluster
File System (CFS) or Veritas Cluster Volume Manager (CVM)
version 4.1.
Continentalclusters Product Features
The Continentalclusters product has the following basic features:
• Continentalclusters works with any type of data replication. A set of
guidelines for integrating your data replication technology can be
found in Chapter 4 of the Designing Disaster Tolerant HA Clusters
Using Metrocluster and Continentalclusters user’s guide on:
www.docs.hp.com -> High Availability -> Continentalclusters
Continentalcluster provides a pre-integrated data replication
solution using HP StorageWorks Continuous Access XP, Continuous
Access EVA or EMC SRDF with the separately purchased products
Metrocluster Continuous Access XP, Metrocluster Continuous Access
EVA, and Metrocluster with EMC SRDF. An alternative to using the
pre-integrated data replication solution a customer-selected data
replication solution can be chosen by following the integration
guidelines.
• A recovery pair in a Continentalclusters consists of one primary
cluster and one recovery cluster. One or more recovery pairs can be
configured in a continental cluster with a common recovery cluster.
Failover of a specific package occurs in one direction from the
primary cluster to the recovery cluster. Each data center can serve as
both primary and recovery cluster for different packages. In the
cascading failover configuration, the primary cluster can be a
metropolitan cluster using EMC SRDF or Continuous Access XP.
