So I read John McDonough's blog post Launch UCS KVM from a script and naturally set out to create a powershell script to do so because it sounded like a cool script. Lately I have been trying to make all my UCS scripts use 100% Cisco provided cmdlets rather than some of my custom ones so I have to use a lot of Invoke-XmlCommand. The final part was to get the authentication token from the UCS. Sending the command over UCS returns null. No errors or anything written to console but taking the exact same XML string and sending it to the UCS over a custom function to send http posts to the UCS returns values. I have tried this with the two cookie attributes added in to the Invoke cmdlet and without them and with any combo of one or the othere. Any idea why the Invoke-XmlCommand doesn't do anything? Is there something different about the method that doesn't work with Invoke-XmlCommand?
 
 
 
$Token = Invoke-XmlCommand "<aaaGetNComputeAuthTokenByDn cookie=""$($CurrentUCSMInstance.cookie)"" inCookie=""$($CurrentUCSMInstance.cookie)"" inDn=""$($SP.pnDn)"" inNumberOf=""2""></aaaGetNComputeAuthTokenByDn>"

Thanks,
Kevin
