OnCommand Unified Manager 9.5
Unable to delete cluster from OnCommand Unified Manager. Cluster removal process stuck displaying "Deletion in progress" in the "Description" field on the "Configuration/Cluster Data Sources" page.
Collecting a support bundle, or directly looking at collected log "ocumserver.log", will have the following entry:
