Switch disks to persistent mode via vmware sdk api calls

Question

Update: The preferred solution would be something that uses the VmWare toolkit for .NET and achieves the following

One of the tasks that we now need to perform (if possible) is to toggle the virtual hard disks from non-persistent to persistent mode and vice versa.

I have tried looking for the correct API calls but haven't found any yet. Does anyone know if this can be done via the API calls?

Although I haven't done this exact operation, I have done similar operations through the ReconfigVm task: http://www.vmware.com/support/developer/vc-sdk/visdk41pubs/ApiReference/vim.VirtualMachine.html#reconfigure

You will need to set up a VirtualMachineConfigSpec with an upodated VirtualDevice whose VirtualDeviceBackingInfo has the desired persistence type in its diskMode attribute. The data objects are documented here:

According to the VMware vSphere PowerCLI Cmdlets Reference, this should do the job:

Get-HardDisk -VM $myVM | Set-HardDisk -Persistence "Independent(Non)Persistent"
