Hi [NAME]-REJIS  In the OME appliance, you can Navigate to "Devices", scroll down to "Plugin Groups" --> "Physical Hierarchy".  Expand the hierarchy and use the more options against the Rack group to delete it.  [IMAGE]  
Is there any way to delete a rack in the Power Manager plugin? I was trying to get the rack names consistent, but now racks for both the old name and new name are listed. So far I haven't found a way to delete the old rack.
