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:
