Subject Re: unable to delete shared network
Date Wed, 08 Jan 2014 02:31:58 GMT
John, 

I think the problem here is that the VR has a IP allocated on the Shared
network, and that has to be removed before the shared network can be
deleted. Everything has to be off the network before you can remove a
network. 

You can delete the VR and make sure there are no other NICs allocated to
that network. Once that is done you should be able to delete via the GUI
without DB intervention.

Thanks
Matt
