Spotlight on SQL Server Enterprise 11.7 - Management Pack for SCOM User Guide

Clusters - Node Unavailable Alarm

The Clusters - Node Unavailable Alarm alarm is raised when Spotlight detects that at least one cluster node (computer system) is not currently running as part of the cluster.

This alarm can only be raised when you are connected to a SQL Server that is running as part of a Microsoft Cluster Server (MSCS).

When a cluster node (i.e. a computer system that participates in a cluster) is unavailable, the workload that it normally processes will fail over to other computer systems in the cluster, resulting in lower performance.
