Physical Data Replication for ContinentalClusters Using Continuous Access XP
Chapter 6 285
6 Physical Data Replication for
ContinentalClusters Using
Continuous Access XP
This chapter shows how to use the MetroCluster/CA package
environment file template to set up data replication between the primary
and secondary packages in a continental cluster that uses the HP
StorageWorks E Disk Array XP Series with Continuous Access XP.
These packages run on different clusters within the continental cluster.
This chapter has the following sections:
• Overview
• Preparing the Continental Cluster for Data Replication
• Creating and Exporting LVM Volume Groups
• Setting up a Primary Package on the Primary Cluster
• Setting up a Recovery Package on the Recovery Cluster
• Setting up the Continental Cluster Configuration
• Switching to the Recovery Cluster in Case of Disaster
• Failback Scenarios
• Maintaining the Continuous Access XP Data Replication
Environment
It is assumed that readers are already familiar with MC/ServiceGuard
configuration tasks, continental cluster concepts and installation
procedures, HP StorageWorks E Disk Array XP Series and Continuous
Access XP concepts and Raid Manager configuration and use.
NOTE This chapter is for ContinentalClusters users only. Users of
MetroCluster with Continuous Access XP should not use the procedures
in this chapter. Refer instead to Chapter 3, “Building a Metropolitan
Cluster Using MetroCluster/CA.”
