- Hope you have upgraded the Data Protector in all the clients and now all the Clients in the CellManager(CM) are of same version.
- Make sure Vepa(Virtual Environment Integration) also installed along with VMWare GRE agent in all the mount proxies.
- You should able to remove any mount proxy from the CM. Incase any errors from DP, you can manually remove from the client-> Control Panel. Just reconnect the GUI to refresh the changes.
- Same mount proxy can be used for VC5.1 as well as VC5.5. (Only Linux Guest VM needs a Linux mount proxy)
- Is VC5.1 GRE working?
