When you initially go into Business view and you click on the different tabs (Workspace, Cluster, Host, Storage, VM) there is a column labed "Group" in which you can add it to. By default it comes with "Mission Critical" and "Other"
Well, to start we just assinged our Production cluster to "Missioin Critical" but realized this was a good definition. But, it wont let me change it. At least not the same way i was able to assign it. It was just a drop down box before, now there is nothing
