Defining DSE topologies

Define the topology for DSE at the cluster, datacenter, and node levels.

The Lifecycle Manager (LCM) topology consists of cluster, datacenter, and node models. LCM uses the topology for installing and configuring DataStax Enterprise (DSE) at these levels. When installing and configuring DSE clusters, the topology provides flexibility and powerful inheritance mechanisms.

The following table explains each topology status that can display in the LCM interface:

Table 1. Topology status legend
Status Icon Description
Not run (red flag) An install job has not been run on the topology. See running a job.
Import (unmanaged cluster) (red plus sign) An existing cluster is not being managed by Lifecycle Manager. Click Start Managing and follow instructions to automatically import the cluster.
Success The job ran successfully on a topology model (cluster, datacenter, or node).
Failure (red universal no access symbol) The job run on a topology model (cluster, datacenter, or node) failed. Investigate the issue by drilling into the job details. Try running the job again.
