I am running OpManager build 11600 and monitor our VMWare virtual machines through the VCenter.  The problem i am having is that it doesn't seem to be picking up the fact that a cluster has been deleted and a new one created so i am missing ESX hosts and therefore not motioning all VMs.

Is there a way to resolve this without having to delete the virtual center and re-add, as I don't want to lose any monitoring data?

Thanks

Jon
