Configuring a High

Availability Cluster

This chapter explains how to configure SR2122-2 Storage Routers in a cluster to
allow the storage routers to back each other up in case of failure. The following
tasks are covered:

■

Prerequisite Tasks

■

Adding the Storage Router to a Cluster

■

Changing Clusters

High availability clusters can be configured using CLI commands, as described in
this chapter, or via the web-based GUI. To access the web-based GUI, point your
browser to the storage router management interface IP address. After logging on,
click the Help link to access online help for the GUI.
