Problem with VM NIC Config on DVS

[vMarkusK1985]

Hallo,

I created a Workflow to switch all NICs of a VM to a temporary DV Portgroup and back to the original one.

All Logs look Fine, but nothing happens (Reconfigure Task in vCenter is running but nothing is changed):

You can see that something is wrong in the marked Log entries, this must be different DVPs…

I have attached the Documentation and the workflow itself.

Maybe I am totally blind…

I added some more debug check after first switch:

System.log ("Switching to Temp Network Completed."); 
System.debug ("actionResult_ActualNetworkAfterTempSwitch: " + actionResult_ActualNetworkAfterTempSwitch.Name);
if ( actionResult_ActualNetworkAfterTempSwitch != temp_dvPortgroup){
  System.error ("Switching to Temp Network failed."); 
  System.debug ("actionResult_ActualNetworkAfterTempSwitch: " + actionResult_ActualNetworkAfterTempSwitch);
  System.debug ("temp_dvPortgroup: " + temp_dvPortgroup);
  }
else {
  System.log ("Switching to Temp Network Completed."); 
  }
System.log ("...Switching Back."); 

And the resultis as expected:

What is wrong with this action?

[dvatov]

var active_dvPortgroup = actionResult_ActualNetwork;

At the same time active_dvPortgroup is output parameter of the scripting block. Isn't this declaration hiding the output parameter?

[vMarkusK1985]

Hi,

I did that because the Action "getNetworkForGivenNic" has a wrong type of output... I'm not shure if this works (it looks like), but the Problem is earlier than the usage of this var in the workflow:  Also the "Real" Input of "temp_dvPortgroup" has no effect in NIC-Change...

[vMarkusK1985 · Accepted solution]

Hi,

i found the Problem:

- The Action "getNetworkForGivenNic" uses ID 1 for first Nic

- but the Workflow "Connect virtual machine NIC number to distributed virtual port group" uses ID 0 for the Same NIC

So:

// modify the NIC ID for Change Workflow
var NicNumer = loopCounter - 1;
