<# .SYNOPSIS This script sets a new Management Point for a SCOM Agent .PARAMETER ManagementPoint defines the Management Point or Gateway to use .PARAMETER ManagementGroup defines the Management Group to use .EXAMPLE Set-ScomManagementPoint.ps1 -ManagementPoint 'gateway.domain.net' -ManagementGroup 'MG001' #> Param ( [string]$ManagementPoint , [string]$ManagementGroup = 'MG001' ) try { $SCOMAgent = New-Object -ComObject AgentConfigManager.MgmtSvcCfg } catch { Write-Output "no SCOM Agent found" } if ( -not ( [string]::IsNullOrEmpty( $SCOMAgent ) ) ) { Stop-Service -Name HealthService $StateDirectory = Get-ItemPropertyValue -Path HKLM:\SYSTEM\CurrentControlSet\services\HealthService\Parameters -Name 'State Directory' $CurrentMGs = $SCOMAgent.GetManagementGroups() foreach ( $CurrentMG in $CurrentMGs ) { try { $SCOMAgent.RemoveManagementGroup( $CurrentMG.managementGroupName ) } catch { throw "couldn't remove current Management Group '$( $CurrentMG.managementGroupName )'" } } $ChildItems = Get-ChildItem -Path $StateDirectory foreach ( $ChildItem in $ChildItems ){ try { Remove-Item -Recurse -Force -Confirm:$false -Path $ChildItem.FullName } catch { throw "couldn't remove '$( $ChildItem.FullName )'" } } $SCOMAgent.AddManagementGroup($ManagementGroup, $ManagementPoint, 5723) $SCOMAgent.ReloadConfiguration() $MGs = $SCOMAgent.GetManagementGroups() foreach ( $MG in $MGs ) { Write-Output "$( $MG.managementGroupName ):$( $MG.ManagementServer )" } } |
please note, that this script will remove the old assignement and clean up the state directory. if you don’t cleanup the state directory, the agent will after a service restart be assigned again to the old gateway.
