Hi,
Please find the script.
need to have access and you can provide list of servers in text file.
 param([int32]$TimeMin, [string]$Reason, [string]$Comment)
                $api = new-object -comObject 'MOM.ScriptAPI'
                Import-Module operationsmanager
                New-SCOMManagementGroupConnection
                $Servers = Get-Content "ServerList.txt"
                $Time = (Get-Date).Addminutes($TimeMin)
                Foreach ($Server in $Servers)
                                #Get Computer instance
                                $ComputerClass = Get-SCOMClass -Name Microsoft.Windows.Computer
                                $ComputerClassInstance = Get-SCOMClassInstance  -Class $ComputerClass | Where {$_.DisplayName -eq $Server}
                                If ($ComputerClassInstance.InMaintenanceMode -eq $true)
                                #Write-Host $Server " is in maintenance mode"
                                Write-Host $Server" already under Maintenance Mode or not accessible by SCOM, skipped from script execution" -foregroundcolor "red"
                                $api.LogScriptEvent('MaintenanceModeScript.ps1', 201, 1, "$Server already found under MM, skipped from script execution")
                                Else
                                #Write-Host $Server " is NOT in maintenance mode, attempting to put in MM......."
                                If ($ComputerClassInstance -ne $Null)
                                                $HealthServiceWatcherClass = Get-SCOMClass -name:Microsoft.SystemCenter.HealthServiceWatcher
                                                #Get Health Service Watcher Class instance of the server
                                                $HSWClass = Get-SCOMClass -Name Microsoft.SystemCenter.HealthServiceWatcher
                                                $HSWClassIns = Get-SCOMClassInstance  -Class $HSWClass | Where {$_.DisplayName -eq $Server}
                                                #Starting the maintenance mode
                                                Start-SCOMMaintenanceMode -Instance $HSWClassIns -EndTime $Time -Reason $Reason -Comment
$Comment
                                                Start-SCOMMaintenanceMode -Instance $ComputerClassInstance -EndTime $Time  -Reason $Reason
-Comment $Comment
                                                Write-Host "Health Service Watcher and Agent server "$Server " kept in maintenance
mode for $TimeMin minutes"  -foregroundcolor "green"
                                                $api.LogScriptEvent('MaintenanceModeScript.ps1', 200, 0, "$Server kept in maintenance
mode for $TimeMin minutes")
                                Else
                                                Write-Host $Server" not found in Domain" -foregroundcolor "red"
                                                $api.LogScriptEvent('MaintenanceModeScript.ps1', 202, 1, "$Server not found in domain")
