Setting a new advanced-setting

[larstr]

Hi,

Changing an existing advanced-setting is no problem, but setting a new one is a bit challenging.

PS C:\> get-vmhost esxihost.fqdn | Get-AdvancedSetting -Name "/Net/TcpipHeapSize"| Set-AdvancedSetting -Value 32 -Confirm:$false
Get-AdvancedSetting : 16.09.2021 07:38:35       Get-AdvancedSetting             "/Net/TcpipHeapSize" option doesn't exist.

Any ideas how this could be solved?

Shouldn't you be using New-AdvancedSetting for that?
I normally would use a Try-Catch

$esx = Get-VMHost -Name esxihost.fqdn

Try{
   Get-AdvancedSetting -Entity $esx -Name '/Net/TcpipHeapSize' -ErrorAction Stop |
   Set-AdvancedSetting ...
}
Catch{
   New-AdvancedSetting -Entity $esx ....
}

It says it's not supported.

PS C:\> get-vmhost esxihost.fqdn | new-AdvancedSetting -Name "/Net/TcpipHeapSize" -value 32

Strange, I didn't realise that.
On the other hand, Set-VMHostAdvancedConfiguration says it is deprecated and to use Set-AdvancedSetting.

That would mean the only valid alternatie is to use Get-EsxCli, and the $esxcli.system.settings.advanced.set.Invoke(@{....}) command

Thank you Luc!

I ended up with the following:

param (
    [string]$clustername = $( Read-Host "Enter clustername: " )
 )

function Advanced-vmhostset{
  $esxihost = get-vmhost $args[0]
  $options= $args[1]
  $value= $args[2]
  Try{
     Get-AdvancedSetting -Entity $esxihost -Name $options -ErrorAction Stop |
     Set-AdvancedSetting -Value $value -Confirm:$false
   }
   Catch {
     $vmhost=get-vmhost $esxihost
     $esxcli = Get-EsxCli -VMHost $vmhost -V2
     $opt= $esxcli.system.settings.advanced.set.CreateArgs()
     $opt.option = $options
     $opt.intvalue = $value
     $esxcli.system.settings.advanced.set.Invoke($opt)
    }
  }

$hosts=get-cluster $clustername|get-vmhost

foreach($esxihost in $hosts){
  Advanced-vmhostset $esxihost "/Net/TcpipHeapSize" 32
  }
