Set-NetworkAdapter - Object reference not set to an instance of an object.

[WallaceTechUK]

Guys.

I have moved a whole bunch of VM's from one cluster that had a Standard vSwitch to a cluster than has a Distributed vSwitch. Now I am banging my head againt the wall with this one. I thought the code below would work but i get a message

Set-NetworkAdapter

Object reference not set to an instance of an object.

What am i doing wrong here?

--------------

Connect-VIServer SERVER1

$OldNetwork = "EU VDI ILIO Storage Network"

$NewNetwork = "EU UCS VDI Port Group(VDI Desktops - VLAN148)"

Get-VM |Get-NetworkAdapter |Where {$_.NetworkName -eq $OldNetwork } |Set-NetworkAdapter -NetworkName $NewNetwork -Confirm:$false

--------------  Example 4 --------------

C:\PS>$myNetworkAdapters = Get-VM | Get-NetworkAdapter -Name "Network adapter 1"

$myVDPortGroup = Get-VDPortgroup -Name MyVDPortGroup

Set-NetworkAdapter -NetworkAdapter $myNetworkAdapters -Portgroup $myVDPortGroup

Retrieves all network adapters named "Network adapter 1" from all virtual machines and connects them to the specified distributed port group.

Which PowerCLI version are you using ?

Do a Get-PowerCLIVersion

What does

Get-VM |Get-NetworkAdapter

show after the move to the other cluster, more specifically on the NetworkName property ?

Hello. Thanks for the replay.

Get-VM Test | Get-NetworkAdapter -Name "Network adapter 1"  - Returns correct info

Get-VDPortgroup -Name "EU VDI Workstations PortGroup" - Returns the correct Port Group info

When I run all the script together i get the message below.

Set-NetworkAdapter : 09/09/2015 08:55:25

Set-NetworkAdapter

The specified DV portgroup 'EU VDI Workstations

PortGroup' can not be used for vnic connection: Invalid portgroup type

--------------

$myNetworkAdapters = Get-VM Test | Get-NetworkAdapter -Name "Network adapter 1"

#

$myVDPortGroup = Get-VDPortgroup -Name "EU VDI Workstations PortGroup"

#

Set-NetworkAdapter -NetworkAdapter $myNetworkAdapters -Portgroup $myVDPortGroup

Blind gues: maybe you receive this error, because one of the portgroup is vmkernel only?

[WallaceTechUK]

Hello.

My VMKernel is not on any of the distributed switches.

[LucD]

Can you try placing the portgroup names between single quotes ?

It might be that the parenthesis are interpreted as meta characters

[WallaceTechUK]

Thank you.

Still the same issue and error message

Set-NetworkAdapter : 09/09/2015 15:51:14

Set-NetworkAdapter

The specified DV portgroup 'EU VDI Workstations

PortGroup' can not be used for vnic connection: Invalid portgroup type.   

Changed Script

-----------------------------------

$myNetworkAdapters = Get-VM Test | Get-NetworkAdapter -Name 'Network adapter 1'

$myVDPortGroup = Get-VDPortgroup -Name 'EU VDI Workstations PortGroup'

Set-NetworkAdapter -NetworkAdapter $myNetworkAdapters -Portgroup $myVDPortGroup

[WallaceTechUK]

OK.

I have been a bit of a dick. I was connecting directley to the host and not to vCenter. I was trying to be safe and only deal with my test host. Thinking about it now i should have been connecting the the vCenter.  However the issue i have now is this,

Code

-----

$myNetworkAdapters = Get-VM Test | Get-NetworkAdapter -Name 'Network adapter 1'

$myVDPortGroup = Get-VDPortgroup -Name 'EU VDI Workstations PortGroup'

Set-NetworkAdapter -NetworkAdapter $myNetworkAdapters -Portgroup $myVDPortGroup

Error message

-----

Get-NetworkAdapter : The input object cannot be bound to any parameters for the command either because the command does not take pipeline

input or the input and its properties do not match any of the parameters that take pipeline input.

Strange.. it works for me, however I used double quotes and I don't have spaces in dVportgroup names:

$myNetworkAdapters = Get-VM wintest1 | Get-NetworkAdapter -Name "Network adapter 1"
myVDPortGroup = Get-VDPortgroup -Name "v4094--BLACK_HOLE"
Set-NetworkAdapter -NetworkAdapter $myNetworkAdapters -Portgroup $myVDPortGroup

try with oneliner (sorta, you'll still need myVDportGroup variable):

$myVDPortGroup = Get-VDPortgroup -Name "EU VDI Workstations PortGroup"
Get-VM Test| Get-NetworkAdapter -Name "Network adapter 1" |Set-NetworkAdapter -Portgroup $myVDPortGroup

If still unsuccessful, please provide output of "get-member" command against your variables (gm is an alias):

$myNetworkAdapters|gm
$myVDPortGroup|gm

[LucD]

Did you check that 'Get-VM Test' actually returns something ?

[WallaceTechUK]

Odd.

Using your code below works for me. I am trying to see what is different about it all. Want to see where i went wrong or what i missed.

$myNetworkAdapters = Get-VM wintest1 | Get-NetworkAdapter -Name "Network adapter 1" 

myVDPortGroup = Get-VDPortgroup -Name "v4094--BLACK_HOLE" 

Set-NetworkAdapter -NetworkAdapter $myNetworkAdapters -Portgroup $myVDPortGroup 

Thank you for taking the time to help me on this issue. its very very much appriciated.
