ErrorAction for Get-VMHostNetworkAdapter broken

Another day, another bug… The Get-VMHostNetworkAdapter CMDlet does not handle the ErrorAction parameter correctly.

The ErrorAction parameter still throws an error even if the “SilentlyContinue” option is selected. This is a problem if you just want to check the existence of NICs on a ESX Host.

$ESXHost = Get-VMHost esx.fqdn -ErrorAction:Stop
$dvSwitch = Get-VDSwitch -Name dvSwitch1 -Location virtualDatacenter -VMHost $ESXHost -ErrorAction:Stop
$Portgroup = Get-VDPortgroup -Name “Management Network” -VDSwitch $dvSwitch -ErrorAction:Stop
Get-VMHostNetworkAdapter -VMHost $ESXHost -VMKernel:$true -VirtualSwitch $dvSwitch -PortGroup $Portgroup -ErrorAction:SilentlyContinue | out-null

If the Host has no vmk NIC configured on the “Management Network” portgroup of dvSwitch1 the CMDlet still throws a error message. My workaround is a empty try/catch function to suppress the error message.

try
{
Get-VMHostNetworkAdapter -VMHost $ESXHost -VMKernel:$true -VirtualSwitch $dvSwitch -PortGroup $Portgroup -ErrorAction:SilentlyContinue | out-null
}
catch
{
#silence
}

Also for this bug a VMware SR is open. Let’s see if this bug is fixed in the next PowerCLI version.
