Delete clusters using the job manager
We can submit the Delete cluster job to remove a cluster from the flexible management environment.
Start the job manager, the dmgr, and the targets on which the cluster resides.
Each cluster that you want to delete must be a managed resource of the job manager.
We can use the admin console of the job manager or the dmgr to delete a cluster from one or more managed targets. From the console, choose the Delete cluster job, specify job options, review the summary, and submit the job.
The job stops the cluster, if it is running, and removes the cluster from the flexible management environment and from the dmgr node.
Instead of using a console, you can run the deleteCluster job script in the AdministrativeJobs command group. See the Administrative job types topic.
