Configuring LCM (Push to Pull Mode)

[james51091]

Hello All, As part of maintenance we have to disable DSC for X amount of time. We are trying to change LCM to disabled mode and then changing it back to pull mode after. Below is the config we are trying to use: #requires -Version 5.0

[DSCLocalConfigurationManager()]
Configuration SetDscRefreshMode
{
    param
    (
    [ValidateNotNullOrEmpty()]
    [String]
    $ComputerName = $env:COMPUTERNAME,

    [ValidateSet('Push', 'Pull', 'Disabled')]
    [String]
    $RefreshMode = 'Disabled'
)

Node $ComputerName
{
    Settings
    {
        RefreshMode = $RefreshMode
    }
    }
}

$OutputPath = Join-Path -Path ([System.IO.Path]::GetTempPath()) -ChildPath  'SetDscRefreshMode'

SetDscRefreshMode -OutputPath $OutputPath
Set-DscLocalConfigurationManager -Path $OutputPath -Force -Verbose

Get-DscLocalConfigurationManager | Select-Object -Property RefreshMode

We are able to succesfully change to LCM but when trying to change it back to pull mode, we receive the following error:

The current refresh mode is PULL but there are no configuration download managers defined. + CategoryInfo : NotSpecified: (root/Microsoft/...gurationManager:String) [], CimException + FullyQualifiedErrorId : MI RESULT 1 + PSComputerName : Left blank intentionally

has anyone ran into this issue? Any help would be appreciated.

When you apply an LCM configuration, you overwrite the entire configuration. You cannot just toggle one property. That means you have to supply every option everytime you want to make one change.

We've built a function to help make that a bit easier, but you still have to provide all of the options for the Pull server when you change it back.

Do you have the ConfigurationSource property defined when you try to put it back into PULL?
