Add a pNic to a Standard vSwitch

[avarcher]

I hope there is an easy answer here. I have created the vSwitch, "vSwitch1", and all I need to do now is add vmnic1 to it. I cant find any existing workflows or actions so I resort to Onyx;

// ------- UpdateVirtualSwitch -------

var spec = new VcHostVirtualSwitchSpec();

spec.numPorts = 128;

spec.bridge = new VcHostVirtualSwitchBondBridge();

spec.bridge.nicDevice = System.getModule("com.vmware.onyx").array(String, 1);

spec.bridge.nicDevice[0] = "vmnic1";

spec.policy = new VcHostNetworkPolicy();

spec.policy.security = new VcHostNetworkSecurityPolicy();

spec.policy.security.allowPromiscuous = false;

spec.policy.security.macChanges = true;

spec.policy.security.forgedTransmits = true;

spec.policy.nicTeaming = new VcHostNicTeamingPolicy();

spec.policy.nicTeaming.policy = "loadbalance_srcid";

spec.policy.nicTeaming.reversePolicy = true;

spec.policy.nicTeaming.notifySwitches = true;

spec.policy.nicTeaming.rollingOrder = false;

spec.policy.nicTeaming.failureCriteria = new VcHostNicFailureCriteria();

spec.policy.nicTeaming.failureCriteria.checkSpeed = "minimum";

spec.policy.nicTeaming.failureCriteria.speed = 10;

spec.policy.nicTeaming.failureCriteria.checkDuplex = false;

spec.policy.nicTeaming.failureCriteria.fullDuplex = false;

spec.policy.nicTeaming.failureCriteria.checkErrorPercent = false;

spec.policy.nicTeaming.failureCriteria.percentage = 0;

spec.policy.nicTeaming.failureCriteria.checkBeacon = false;

spec.policy.nicTeaming.nicOrder = new VcHostNicOrderPolicy();

spec.policy.nicTeaming.nicOrder.activeNic = System.getModule("com.vmware.onyx").array(String, 1);

spec.policy.nicTeaming.nicOrder.activeNic[0] = "vmnic1";

spec.policy.offloadPolicy = new VcHostNetOffloadCapabilities();

spec.policy.offloadPolicy.csumOffload = true;

spec.policy.offloadPolicy.tcpSegmentation = true;

spec.policy.offloadPolicy.zeroCopyXmit = true;

spec.policy.shapingPolicy = new VcHostNetworkTrafficShapingPolicy();

spec.policy.shapingPolicy.enabled = false;

managedObject.updateVirtualSwitch("vSwitch1", spec); // HostNetworkSystem

I change the last line to ;

currentHost.configManager.networkSystem.updateVirtualSwitch(nameOfSwitchForProduction, spec);

Where currentHost is the host object and nameOfSwitchForProduction is the valid string name for the created switch.

Everytime I get 'The object or item referred to could not be found' yet the switch vSwitch1 is there and vmnic1 exists.

Where am I going wrong?

Thanks, Andy.

Hi Andy,

that could be an easy one, and your last line already shows the answer in the comment:

The ManagedObject in the last line may not be the Host itself, but its NetworkHostSystem-object:

var theHostsHostNetworkSystem = currentHost.configManager.networkSystem;
theHostsHostNetworkSystem.updateVirtualSwitch("vSwitch1", spec); // HostNetworkSystem

So, back to school, and repeat what I tought you about the API Explorer, API Reference and Managed Object Browser :smileysilly:.

edit: Forget about this answer, I just did not read properly your code. So, note to myself: back to school, and repeat what you learned about readCarefullyBeforeOpenYourMouth :smileyblush::smileyblush::smileyblush:.

Cheers,

Joerg

ok, maybe this one is not that easy: You have to create the arrays manually, and can not use the Onyx-method (might be related to a bug in vCO => see release notes somewhere under misc.. known issues):

// ------- UpdateVirtualSwitch -------
var spec = new VcHostVirtualSwitchSpec();
spec.numPorts = 128;
spec.bridge = new VcHostVirtualSwitchBondBridge();
//spec.bridge.nicDevice = System.getModule("com.vmware.onyx").array(String, 1);
//spec.bridge.nicDevice[0] = "vmnic1";
var nicArray = new Array();
var nic = new String("vmnic1");
nicArray.push(nic);
spec.bridge.nicDevice = nicArray;
System.debug("spec: " + spec);
System.debug("nicdevice: " + spec.bridge.nicDevice);
var confMgr = currentHost.configManager;
var theHostsHostNetworkSystem = confMgr.networkSystem;
theHostsHostNetworkSystem.updateVirtualSwitch("vSwitch1", spec); // HostNetworkSystem

So: Never blindly trust Onyx' output, only let it guide you to the proper path in the API Reference! (, my young Padavan )

Cheers,

Hi Joerg

I'm glad to have presented you with a challenge :smileydevil: and I'm happy to report 100% success :smileylaugh:.

You are correct on all levels with this, I think you did tell me that the network api organisation was probably one of the more complex and that is how I am experienceing it so maybe not the best one to make a start with.

So, use Onyx as a guide and use the API documentation.

Where I am struggling a bit is taking what I'm reading in the API and applying it to workflows. However, I think I'll take your working answer and study it beside the API till I get it.

Thanks again oh master

Cheers, Andy

Hi everybody

it tried the code snippet and it failed

After some testing I replaces this region:

var nicArray = new Array();

var nic = new String("vmnic1");

nicArray.push(nic);

spec.bridge.nicDevice = nicArray;

with this one:

var nicArray = new Array();

nicArray.push("vmnic1");

spec.bridge.nicDevice = nicArray;

after that it worked fine for me. But I don´t have a clue where the difference in these code snippets is.

I hope it helps anyone out there. And if it´s me who can´t remember why it didn´t work and finding this post.
