Configuring a High Availability Cluster
This chapter explains how to configure SN 5428-2 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, page 10-1
• Creating a Cluster, page 10-2
• Joining Stand-alone Storage Routers in a Cluster, page 10-6
• Changing Clusters, page 10-7
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’s management
interface IP address. After logging on, click the Help link to access online help for the GUI.
Note SN 5428-2 Storage Routers that are deployed for transparent SCSI routing or FCIP cannot participate in
a high availability cluster.
Prerequisite Tasks
All storage routers that will participate in a cluster must have connectivity to the same hosts and the same
storage systems, and must be connected to each other through their management and HA interfaces.
Note At least one of the interface connections must be live; you cannot connect storage routers in a cluster
using cross-over cables.
