Cluster add failed. Cluster already exists.



I see this message adding a cluster into OnCMD UM 6.4RC1, except that the cluster isn't in the dashboard or listed as a cluster in Health -> Storage -> Clusters.  It was previously added and removed, and I'm guessing something still "remembers" it.


Does anyone know how to purge an old cluster out of the databases, or have any ideas?




Re: Cluster add failed. Cluster already exists.



Did you have any integration configured with OPM in this scenario?  If so, was it partial (event publication to UM from OPM) or full integration? 

Were there any errors removing the datasource when that action was executed?

Correction of this problem will involve some deeper investigation -- Please open a case with the details of the clsuter add/remove/readd actions, error messages, and the intergration qeustion above.

Hi @MarkDoyle



Check this post for steps to remove the stale association entry:


If you had it integrated with UM (partial or full integration) and probably need to clean up that too needing more steps [that NetApp support could help you with].
