Code to delete vNIC on VM during VM provisioning in Orchestrator

[Tom Lee]

Hi,

Does anyone have code to delete a vNIC on a VM during VM provisioning in Orchestrator. Our templates contain multiple vNICs to accommodate various builds. Some builds do not require the additional vNICs and would like them removed during the provisioning process in Orchestrator. 

Thanks!

Hi,

I think I have something similar. If it's not urgent, give me some time. I will try to find it.

So,

this is a minimum working code:

var spec = new VcVirtualMachineConfigSpec();
var deviceChange = new Array();
deviceChange[0] = new VcVirtualDeviceConfigSpec();
deviceChange[0].device = new VcVirtualVmxnet3();
deviceChange[0].device.key = 4000;
deviceChange[0].operation = VcVirtualDeviceConfigSpecOperation.remove;
spec.deviceChange = deviceChange;
spec.virtualNuma = new VcVirtualMachineVirtualNuma();
vm.reconfigVM_Task(spec);

A few comments:

1. `vm` - is a VcVirtualMachine object.
2. This code will work only if type of the NIC is VMXNET3.
3. This code will work only if there is only one NIC.

To make this code more generic, it is worth to cover:

1. Convert this code into a function/s.
2. All NIC types.
3. Check if there are multiple NICs. If so, remove the required one by getting first proper deviceController ID and setting it into `deviceChange[0].device.controllerKey = XXX`. The same for `deviceChange[0].device.key`.

If there is only one NIC:

1. default `deviceChange[0].device.key` is 4000.
2. default `device.controllerKey` is 100.

PS. If `device.controllerKey` is not provided, it will always remove the first NIC.

Please let me know if you need more details.

Thanks for the code and explanation. The NIC we need to delete is always 'Network adapter 2'.

How do you go  about getting the `deviceChange[0].device.controllerKey' and  `deviceChange[0].device.key` for the Network adapter 2?

Hi, Tom.

You can take this example from my repo. It will loop over network devices and return them as an object. Therefore, you can check each NIC (by labels or any other property) and find one you want to remove.

Thanks for the additional code. It worked perfectly once the correct device.key was inputted. 

Much appreciated!
