Removing Unwanted Plugins from vCenter

Some of the plugins for vCenter don’t offer an uninstaller.

To unregister a plugin from vCenter follow this method provided by a VMware KB:

Open a web browser and go to http://vcenterserver/mob

Click on Content

Click on ExtensionManager

Copy the name of the plugin you want to unregister

extensionList[“com.emc.EMCStoragePlugin”]

Click on UnregisterExtension

In the text field paste the text into the box and delete all but the part in quotes(e.g.com.emc.EMCStoragePlugin)

click InvokeMethod

 

Refresh the browser and the plugin should be gone from the list

Reconnect to vCenter using the client and the plugin should be gone from Plug-ins-> Manage Plugins list.
