Chapter 8 Cascading Failover in a Continental Cluster

This chapter shows how to create a configuration that allows cascading failover between two sites that are connected via ContinentalClusters. Cascading failover is the ability of an application to fail from a primary to a secondary location, and then to fail to a recovery location on a different site. The primary location contains a metropolitan cluster built with MetroCluster EMC SRDF, and the recovery location has a standard MC/ServiceGuard cluster. The solution will support up to 16 nodes in the primary cluster and 16 nodes in the recovery cluster.

This chapter has the following sections:

It is assumed that readers are already familiar with MC/ServiceGuard configuration tasks, continental cluster installation and configuration procedures, EMC Symmetrix, BCV, SRDF, Symmetrix multi-hop concepts, and Symmetrix Command Line Interface (SymCLI) configuration and use.

	NOTE: This chapter is only for users of ContinentalClusters with the EMC Symmetrix disk array.
