.DESCRIPTION Modify Hotadd settings for a single or all VM's .PARAMETER DisableMem Specify disabling Memory Hotadd .PARAMETER DisableCPU Specify disabling CPU Hotadd .PARAMETER EnableMem Specify enabling Memory Hotadd .PARAMETER EnableCPU Specify enabling CPU Hotadd .PARAMETER VMName Specify a specific VM to change HotAdd settings for .EXAMPLE Invoke-HotAdd -DisableMem Disable Memory HotAdd on all VM's .EXAMPLE Invoke-HotAdd -DisableMem -VMName ExchangeServer Disable Memory HotAdd on a single vm .NOTES Requires the VMware.PowerCLI Module .Link https://github.com/TheTaylorLee/AdminToolbox #> Function Invoke-HotAdd { [CmdletBinding()] param ( [Parameter(Mandatory = $true, ParameterSetName = 'Disable Mem Hotadd')][switch]$DisableMem, [Parameter(Mandatory = $true, ParameterSetName = 'Disable CPU Hotadd')][switch]$DisableCPU, [Parameter(Mandatory = $true, ParameterSetName = 'Enable Mem Hotadd')][switch]$EnableMem, [Parameter(Mandatory = $true, ParameterSetName = 'Enable CPU Hotadd')][switch]$EnableCpu, [Parameter(Mandatory = $false, ParameterSetName = 'Disable Mem Hotadd')] [Parameter(Mandatory = $false, ParameterSetName = 'Disable CPU Hotadd')] [Parameter(Mandatory = $false, ParameterSetName = 'Enable Mem Hotadd')] [Parameter(Mandatory = $false, ParameterSetName = 'Enable CPU Hotadd')] $VMName ) if ($DisableMem) { if ($VMName) { Write-Host "Configuring $VMName" -ForegroundColor Yellow $vmview = Get-VM $VMName | Get-View $vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec $extra = New-Object VMware.Vim.optionvalue $extra.Key = "mem.hotadd" $extra.Value = "false" $vmConfigSpec.extraconfig += $extra $vmview.ReconfigVM($vmConfigSpec) } else { $vms = Get-VM | Get-View foreach ($vm in $vms) { Write-Host "Configuring hotadd on: " -ForegroundColor Yellow -NoNewline Write-Host $vm.name -ForegroundColor Cyan $vmview = Get-VM $vm.name | Get-View $vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec $extra = New-Object VMware.Vim.optionvalue $extra.Key = "mem.hotadd" $extra.Value = "false" $vmConfigSpec.extraconfig += $extra $vmview.ReconfigVM($vmConfigSpec) } } } if ($DisableCPU) { if ($VMName) { Write-Host "Configuring $VMName" -ForegroundColor Yellow $vmview = Get-VM $VMName | Get-View $vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec $extra = New-Object VMware.Vim.optionvalue $extra.Key = "vcpu.hotadd" $extra.Value = "false" $vmConfigSpec.extraconfig += $extra $vmview.ReconfigVM($vmConfigSpec) } else { $vms = Get-VM | Get-View foreach ($vm in $vms) { Write-Host "Configuring hotadd on: " -ForegroundColor Yellow -NoNewline Write-Host $vm.name -ForegroundColor Cyan $vmview = Get-VM $vm.name | Get-View $vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec $extra = New-Object VMware.Vim.optionvalue $extra.Key = "vcpu.hotadd" $extra.Value = "false" $vmConfigSpec.extraconfig += $extra $vmview.ReconfigVM($vmConfigSpec) } } } if ($EnableMem) { if ($VMName) { Write-Host "Configuring $VMName" -ForegroundColor Yellow $vmview = Get-VM $VMName | Get-View $vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec $extra = New-Object VMware.Vim.optionvalue $extra.Key = "mem.hotadd" $extra.Value = "true" $vmConfigSpec.extraconfig += $extra $vmview.ReconfigVM($vmConfigSpec) } else { $vms = Get-VM | Get-View foreach ($vm in $vms) { Write-Host "Configuring hotadd on: " -ForegroundColor Yellow -NoNewline Write-Host $vm.name -ForegroundColor Cyan $vmview = Get-VM $vm.name | Get-View $vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec $extra = New-Object VMware.Vim.optionvalue $extra.Key = "mem.hotadd" $extra.Value = "true" $vmConfigSpec.extraconfig += $extra $vmview.ReconfigVM($vmConfigSpec) } } } if ($EnableCpu) { Write-Host "Enabling CPU Hotadd will disable vNUMA and effect VM Performance" -ForegroundColor Yellow $prompt = Read-Host "Do you wish to continue?
