I have a need to shut down a scom Gateway from old vCenter to new vCenter Environment.
To do this I need to put all Agents behind this Gateway in Maintenance Mode.

Have been trying with this Pshell but didn't work:

Import-Module OperationsManager

$Time = ((Get-Date).AddMinutes(10))
Get-SCOMAgent | where {$_.PrimaryManagementServerName -eq 'GatewayServerName'}|Select DisplayName | Get-SCOMClassInstance | Start-SCOMMaintenanceMode -passthru -EndTime $Time -Comment "Server Migration."

Can someone help in identifying what is a best way to put all Agents behind a Gateway/Management Server in to MM mode.

    Hi,

    I've created a script below that should be what you're looking for:

    Import-Module OperationsManager

$Time = ((Get-Date).AddMinutes(10))
$ErrorActionPreference = 'SilentlyContinue'
$InstanceClass = Get-SCOMClass -Name "Microsoft.Windows.Computer"
$Agents = Get-SCOMAgent | where {$_.PrimaryManagementServerName -eq 'Gateway server name'} | Select DisplayName

Foreach($Agent in $Agents){
    $Instance = Get-SCOMClassInstance -Class $InstanceClass | Where-Object {$_.DisplayName -match $Agent.DisplayName}
    Start-SCOMMaintenanceMode -Instance $Instance -EndTime $Time -Comment "Server Migration." -Reason "PlannedOther"

        #Checking Maintenance Mode
        $Agent
        Get-SCOMMaintenanceMode -Instance $Instance | select ManagementGroup,User,StartTime,ScheduledEndTime,Reason,Comments | fl

    }

    Hi Leon,
    That worked perfectly.

    Need your help in modifying this if I want to let the user choose which Gateway/Mgmt Server to target.

    If i put my values in a variable like this:

    $NthGateway="Server1"
    $SthGateway="Server2"
    $PrimaryMgtServer="Server2"
    $SecondaryMgtServer="Server4"

    Have the script ask:

    "Select SCOM Mgmt/Gateway" 

     Press '1'  for Server1"
 Press '2'  for Server2"
 Press '3'  for Server3"
 Press '4'  for Server4"

    Would you be able to help me out with a proper script to do this?
