Use array values in a foreach loop

Question

Hello guys,

i'm trying to automate some VMware ESXi configurations via PowerShell using the VMware.PowerCLI module.

In my script define an array of ip addresses look like this:

$vMotionIps = @("192.168.0.1","192.168.0.2","192.168.0.3")

For the foreach i use this code:

$vmHosts = Get-VMHost
$vMotionIps = @("192.168.0.1","192.168.0.2","192.168.0.3")

foreach ($vmhost in $vmHosts)
{
$vss= Get-VirtualSwitch -VMHost $vmHost -Name vSwitch0
New-VMHostNetworkAdapter -VMHost $vmHost -PortGroup vMotion -VirtualSwitch $vss -VMotionEnabled:$true -IP $vMotionIps -Subnetmask 255.255.255.0
}

The goal is to set one IP from the array for the parameter "-IP", but i got an error message saying "The specified method is not supported"

May i ask you for what's wrong?

Greetings
Chris

Hi @chrisslicious-os ,

based on this website -IP accepts a string. But you are tyring to insert an array. This might be the isssue.
https://vdc-repo.vmware.com/vmwb-repository/dcr-public/6fb85470-f6ca-4341-858d-12ffd94d975e/4bee17f3-579b-474e-b51c-898e38cc0abb/doc/New-VMHostNetworkAdapter.html

Could please try to use only one IP for $vMotionIps to see if the script is working.

If you would like to add all three vMotionIps it might be required to use a foreach loop.

Not tested!

$vmHosts = Get-VMHost
$vMotionIps = @("192.168.0.1","192.168.0.2","192.168.0.3")

foreach ($vmhost in $vmHosts)
    {
    $vss= Get-VirtualSwitch -VMHost $vmHost -Name vSwitch0
        foreach ($vMotionIp in $vMotionIps) {
            New-VMHostNetworkAdapter -VMHost $vmHost -PortGroup vMotion -VirtualSwitch $vss -VMotionEnabled:$true -IP $vMotionIp -Subnetmask 255.255.255.0
            }
    }
