Discovering Microsoft SQL Server clusters Discovery identifies Microsoft SQL Server instances that are part of a cluster in the CMDB by the cluster name rather than as individual configuration items (CI). An SQL Server instance is not listed as a related item in the CI record for the server that hosts the instance if the instance is part of an SQL Server cluster. Only stand-alone SQL Server instances (instances not joined to a cluster) appear as related items in CI records with the Runs::Runs on relationship. Figure 1.
