We have one report, that changing the setup from a chain setup (netapp01 → netapp02 → netapp03) to a star setup (netapp01 → netapp02 ➕ netapp01 → netapp03) makes stoping some collectors (e.g. get_netapp_cm.pl) with an error of “Instance ‘NETAPP01-SVM01:NETAPP01_SVM01_xxxx01_vol’ already exists – can not continue!

If you see this error in your setup please get in contact with us.
