I got an issue after upgrading from VSC 4 to VSC 6.1.
After upgrade I don't see any controllers, backup jobs or hostory in VSphere.
Looking in the logs it looks like VSC finds filers and volumes etc. But they are not shown in Vsphere.
Even adding a controller is successfull but remains unvisable in the Vsphere web client.
VSC installed as stand alone registered to one V-center server. (We do run Vsphere in linked mode)
