Since we had some trouble updating all our servers to 10.1.1 we reinstalled a few of them.

Because we didn't or can't uninstall the server correctly we now have same stale data in our datebase.

How can we get rid of them?

zman zsd does not work:

[root@ggvmzen:~]$ zman zsd "/Devices/Servers/vvmzen-defekt"

Error: The object selected must be a primary server to run this command.

zman sd also does not work:

[root@ggvmzen:~]$ zman sd "/Devices/Servers/vvmzen-defekt"

Error: "/Devices/Servers/vvmzen-defekt" cannot be deleted as it has associations or dependencies. Please remove the associations or dependencies to delete this object.
