Enabling Zerto Plugin in vSphere Web Client 6.5

Enabling Zerto Plugin in vSphere Web Client 6.5

If you are a Zerto Replication user and have upgraded your VMware environment to 6.5, you may find yourself missing the Zerto plugin that was available in the vSphere C# client. To get the Zerto plugin to display within the vSphere Web Client, we will need to edit the webclient.properties file within vCenter to enable script plug-in support.

I think it goes without saying, but when you are editing any vCenter files, ensure you have a current backup. In this process, we will snapshot our vCenter appliance and create a copy of our webclient.properties file. Let’s begin.

To start, snapshot vCenter.

Next, SSH to vCenter and access the BASH shell with the shell command.

vSphere BASH

Navigate to the vsphere-client folder.

  • cd /etc/vmware/vsphere-client/

Take a backup of webclient.properties file with the cp command.

  • cp webclient.properties webclient.properties.bak

Access the webclient.properties file through the visual editor.

  • vi webclient.properties

Insert new text into the file with the o command.

  • o to edit

Add a row to enable script plug-in support.

  • scriptPlugin.enabled = true

Script Plugin Enable

Save the changes and quit the visual editor by pressing escape and the write (save) quit command.

  • [ESC] + :wq

Now that we have enabled script plug-in support, restart the vSphere client to activate the changes.

  • service-control –stop vsphere-client
  • service-control –start vsphere-client

Once your vSphere Client has restarted, navigate to the Classic Solutions tab.

More than likely, your browser with throw an error the first time viewing the Classic Solutions tab. To remediate, there are a few steps to complete in order to be able to view the web client plug-in through your preferred web browser. These steps should only need to be performed once; on very first load.

More than likely, when you navigate to the Classic Solutions Tab in the vSphere Client, you will still see Content was blocked error. To fix this, open a new tab and browse to the IP address of your ZVM and login to the ZVM.

Navigate back the vSphere Client and Classic Solutions tab. Zerto should now load correctly.

Note: If you are looking to enable to Zerto plug-in in vSphere 6.0, there are two minor changes. First, the location of the webclient.properties file is /var/lib/vmware/vsphere-client. Second, you can use the service vsphere-client restart command to restart your client.
