Start SSH on ESXi host

Hi Guys,

I'm trying to get a scriptable task to start SSH on an ESXi host and its not quite happening. I'll try to explain briefly what I've done so far.

So I've created an attribute / array of ESXi hosts and created an input to use the array as predefined objects. Next I have a scriptable task as follows where its going wrong.

// Start SSH service on ESXi host
var myVcHostServiceSystem = new VcHostServiceSystem() ;
myVcHostServiceSystem.startService("TSM-SSH")

System.log ("Starting SSH service on: " + host.name);

This keeps on failing saying

Unable to create object : VcHostServiceSystem : com.vmware.vmo.plugin.vi4.model.VimHostServiceSystem

Can anybody shed some light?

Thanks

Mr G
