Physical Data Replication for ContinentalClusters Using EMC SRDF
Chapter 7 325
7 Physical Data Replication for
ContinentalClusters Using EMC
SRDF
This chapter shows how to use the MetroCluster/SRDF environment file
template to set up data replication between the primary and secondary
packages in a Continental Cluster that uses the EMC Symmetrix Disk
Array with the Symmetrix Remote Data Facility (SRDF). These
packages run on different clusters within the Continental cluster
configuration. It is assumed that readers are already familiar with
MC/ServiceGuard configuration tasks, MC/ServiceGuard Continental
Cluster concepts and installation procedures, EMC Symmetrix and
SRDF concepts and SymCLI configuration and use.
This chapter has the following sections:
• Overview
• Preparing a Continental Cluster for Data Replication
• Creating and Exporting 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 EMC SRDF Data Replication Environment
• R1/R2 Swapping
NOTE This chapter is for ContinentalClusters users only. Users of
MetroCluster with EMC SRDF should not use the procedures in this
chapter. Refer instead to Chapter 4, “Building a Metropolitan Cluster
Using MetroCluster/SRDF.”
