How to allow OPM to add a cluster that was previously managed by a different OPM instance

Last Updated:

Applies to

  • OnCommand Performance Manager (OPM) 1.1, 2.0, 2.1, 7.0, 7.1.
  • Clustered Data ONTAP: Review the Interoperability Matrix Tool (IMT) to view which versions of Clustered Data ONTAP are compatible with OnCommand Performance Manager 1.1, 2.0, 2.1, 7.0, 7.1.
  • OnCommand Unified Manager (OCUM) 7.3+


OPM registers as an application with clustered Data ONTAP when the cluster is added as a datasource. Changes in clustered Data ONTAP behavior for policy groups between releases 8.2 and 8.3 forced a change in OPM 1.1 to prevent detrimental behavior. A restriction in OPM 1.1 was added to prevent the addition of a single cluster as a datasource to more than one OPM 1.1 instance to prevent detrimental behavior.

In very specific scenarios, it might be essential to remove an OPM application record manually from a cluster, to allow the cluster to be moved to a new or different OPM instance. One or more of the following messages might be reported:

  • You must remove cluster from the instance of OnCommand Performance Manager above before adding it to this instance of OnCommand Performance Manager.
  • Cluster is currently managed by the following instance of OnCommand Performance Manager. Managing a cluster with multiple instances of the same application will impact the performance of the cluster.
  • Cluster settings are modified successfully in Unified Manager. But cluster add failed for Performance Manager. Cluster <<CLUSTER_NAME>> is already managed by OnCommand Performance Manager with system id <<UNIQUE_UUID>> at https://<<IP_ADDRESS>>:443.
