VMware View 6 Power CLI

DevilWAH

Hi,

I have a script to run to change CPU/Memory and so forth on guest desktops in vmware view, but one of the things I need to happen is to first place the desktops in to "maintenance mode" in vmware view. I know View has its own power cli on the connections servers but can any one tell me if there is a simple straight forward way in script to put a machine in maintenance mode and bring it back out?

Our view is set to always power on machines so unless it is disabled the desktops reboot before the script is complete. and I only want to run the script on a sub set of desktops and don't want to make configuration changed on the pool.

Function Enable-MemHotAdd($vm){    $vmview = Get-vm $vm | 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)
}


Function Enable-vCpuHotAdd($vm){
    $vmview = Get-vm $vm | Get-View 
    $vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec


    $extra = New-Object VMware.Vim.optionvalue
    $extra.Key="vcpu.hotadd"
    $extra.Value="true"
    $vmConfigSpec.extraconfig += $extra


    $vmview.ReconfigVM($vmConfigSpec)
}
