17. Configuring NNMi in a High Availability Cluster

High availability (HA) refers to a hardware and software configuration that provides for uninterrupted service in the event some aspect of the running configuration fails. An HA cluster defines a grouping of hardware and software that works together to ensure continuity in functionality and data when failover occurs.

This chapter provides a template for configuring NNMi to run in an HA environment. This chapter does not provide end-to-end instructions for configuring your HA product. The HA configuration commands that NNMi provides are wrappers around the commands for the supported HA products. If you prefer, you can substitute commands specific to the HA product where these instructions specify NNMi-provided commands.
