Unable to change IP Address on VMs

[ganapa2000]

Hi,

I am unable to change the IP address. Subnet, Gateway and DNS on multiple VMs using below as I am getting error

$WPassword = "Password@123"
$pass = ConvertTo-SecureString -AsPlainText $WPassword -Force
$GC = New-Object System.Management.Automation.PSCredential (".\Admin", $pass)

# Defines Variables
$VMName = "App02"
$IP = "192.168.2.52"
$SNM = "255.255.254.0"
$GW = "192.168.2.1"
$DNS1 = "192.168.2.5"
$DNS2 = "192.168.2.6"

$code = @'
$wmi={Get-WmiObject win32_networkadapterconfiguration -filter "ipenabled = 'true'"}
New-NetIPAddress -InterfaceIndex $wmi.Index - IPAddress $IP -PrefixLength $SNM -DefaultGateway $GW
'@

# Starts the setup of the IP, Subnetmask, Gateway and DNS
$vm = Get-VM -Name $vmName

$sInvoke = @{
VM = $vm
GuestCredential = $GC
ScriptText = $ExecutionContext.InvokeCommand.ExpandString($code)
ScriptType = 'powershell'
}
Write-Host "Setting IP address for $VMname" -ForegroundColor Yellow
Invoke-VMScript @sInvoke
Write-Host "Setting IP address completed." -ForegroundColor Green
Get-VM $VMname | Get-NetworkAdapter | Set-NetworkAdapter -NetworkName pg3568 -Confirm:$false

 

Output error

In the $code you have to "escape" the $wmi variable with a back-tick, otherwise it will be substituted by the  ExpandString method.

 

$code = @'
`$wmi={Get-WmiObject win32_networkadapterconfiguration -filter "ipenabled = 'true'"}
New-NetIPAddress -InterfaceIndex `$wmi.Index - IPAddress $IP -PrefixLength $SNM -DefaultGateway $GW
'@@

LucD,

now getting the below error

You have to use the back tick on all variables that you don't want to be substituted.
Also the 2nd occurrence of the $wmi variable (I updated the code above)

LucD,

I tried, still getting errors, so I have modified as below and it is working now. Currently all the variables for IP, Subnet, Gateway and DNS are inside the code. now I would like to know, how can I define those variables from outside of the code ?

$code = @'
# Defines Variables
$VMName = "App02"
$IP = "192.168.2.52"
$SNM = "255.255.254.0"
$GW = "192.168.2.1"
$DNS1 = "192.168.2.5"
$DNS2 = "192.168.2.6"
# Retrieve the network adapter that you want to configure
$adapter = Get-NetAdapter | ? {$_.Status -eq "up"}
# Remove any existing IP, gateway from our ipv4 adapter
If (($adapter | Get-NetIPConfiguration).IPv4Address.IPAddress) {
$adapter | Remove-NetIPAddress -AddressFamily $IPType -Confirm:$false
}
If (($adapter | Get-NetIPConfiguration).Ipv4DefaultGateway) {
$adapter | Remove-NetRoute -AddressFamily $IPType -Confirm:$false
}
# Configure the IP address and default gateway
$adapter | New-NetIPAddress `
-AddressFamily $IPType `
-IPAddress $IP `
-PrefixLength $SNM `
-DefaultGateway $GW
# Configure the DNS client server IP addresses
$adapter | Set-DnsClientServerAddress -ServerAddresses ($DNS1,$DNS2)
'@

$vm = Get-VM -Name $vmName

$sInvoke = @{
VM = $vm
GuestCredential = $GC
ScriptText = $code
ScriptType = 'powershell'
}

Invoke-VMScript @sInvoke

What error do you mean by "I tried, still getting errors"?
The method to declare those variables outside the code block is the method in your original script.
You just have to escape the variables in the code block that you don't want to be substituted.

LucD,

for the first script, After making the suggested changes,  I am getting the below error

ScriptOutput
-----------------------------------------------------------------------------------------------------------------------------

[LucD]

But that is not caused by the variable substitution.
Why do you place the Get-WmiObject inside curly braces?
You are in fact assigning a code block to the $wmi variable

 

 

 

$code = @'
`$wmi=Get-WmiObject win32_networkadapterconfiguration -filter "ipenabled = 'true'"
New-NetIPAddress -InterfaceIndex `$wmi.Index -IPAddress $IP -PrefixLength $SNM -DefaultGateway $GW
'@

LucD,

After making the change, I am getting another error now

$code = @'
`$wmi=Get-WmiObject win32_networkadapterconfiguration -filter "ipenabled = 'true'"
New-NetIPAddress -InterfaceIndex `$wmi.Index -IPAddress $IP -PrefixLength $SNM -DefaultGateway $GW
'@

That is because the Index property of the Win32_NetworkAdapterConfiguration class is not the InterfaceIndex.
With the Win32_NetworkAdapter class, you can find the InterfaceIndex.

I'm wondering where you get this kind of code.

$code = @'
`$netConfig = Get-WmiObject win32_networkadapterconfiguration -Filter "ipenabled = 'true'"
`$netAdapter = Get-WmiObject win32_networkadapter -Filter "index = `$(`$netConfig.Index)"
New-NetIPAddress -InterfaceIndex `$netAdapter.InterfaceIndex - IPAddress $IP -PrefixLength $SNM -DefaultGateway $GW
'@

Perfect...Thank you very much LucD. That worked now without any errors
