4 Building a Metropolitan Cluster
Using MetroCluster/SRDF
This chapter describes the high availability toolkit template for
MetroCluster with EMC SRDF (hereafter known as
MetroCluster/SRDF), which allows you to install and configure an
MC/ServiceGuard metropolitan cluster using the EMC Symmetrix disk
array. It is assumed that readers are already familiar with
MC/ServiceGuard configuration tasks, MC/ServiceGuard metropolitan
cluster concepts and installation procedures, EMC Symmetrix disk
arrays and SRDF concepts, and Symmetrix Command Line Interface
configuration and use.
The topics discussed in this chapter are:
• Overview of MetroCluster/SRDF
• Designing a Disaster Tolerant Architecture for use with
MetroCluster/SRDF
• Preparing a Cluster for MetroCluster/SRDF
• Configuring MC/ServiceGuard Packages for Automatic Disaster
Recovery
• Setting up M by N Configurations
• Maintaining a Cluster that Uses MetroCluster/SRDF
• R1/R2 Swapping
