Putting Server in Maintenance Mode via Power Shell

[Scopus69]

I am trying to use the following script to put one of my servers in
Maintenance Mode:

param
($rootMS,$computerPrincipalName,$numberOfHoursInMaintenanceMode,$comment)

Add-PSSnapin "Microsoft.EnterpriseManagement.OperationsManager.Client"
-ErrorVariable errSnapin;
Set-Location "OperationsManagerMonitoring::" -ErrorVariable errSnapin;
new-managementGroupConnection -ConnectionString:$rootMS -ErrorVariable
errSnapin;
set-location $rootMS -ErrorVariable errSnapin;

$computerClass = get-monitoringclass -name:Microsoft.Windows.Computer
$healthServiceClass = get-monitoringclass
-name:Microsoft.SystemCenter.HealthService
$healthServiceWatcherClass = get-monitoringclass
-name:Microsoft.SystemCenter.HealthServiceWatcher
$computerCriteria = "PrincipalName='" + $computerPrincipalName + "'"
$computer = get-monitoringobject -monitoringclass:$computerClass
-criteria:$computerCriteria
$healthServices = $computer.GetRelatedMonitoringObjects($healthServiceClass)
$healthService = $healthServices[0]
$healthServiceCriteria = "HealthServiceName='" + $computerPrincipalName + "'"
$healthServiceWatcher = get-monitoringobject
-monitoringclass:$healthServiceWatcherClass -criteria:$healthServiceCriteria
$startTime = [System.DateTime]::Now
$endTime = $startTime.AddHours($numberOfHoursInMaintenanceMode)

"Putting " + $computerPrincipalName + " into maintenance mode"
New-MaintenanceWindow -startTime:$startTime -endTime:$endTime
-monitoringObject:$computer -comment:$comment

"Putting the associated health service into maintenance mode"
New-MaintenanceWindow -startTime:$startTime -endTime:$endTime
-monitoringObject:$healthService -comment:$comment

"Putting the associated health service watcher into maintenance mode"
New-MaintenanceWindow -startTime:$startTime -endTime:$endTime
-monitoringObject:$healthServiceWatcher -comment:$comment

I can seem to get it to work. I run the following:

PS C:\> .\AgentMaintenanceMode.ps1 -rootMS: `scomsrv01.acme.com'
-computerPrincipalName: 'websrv02.acme.com' -numberOfHo
ursInMaintenanceMode:1 -comment:'Server is now in MaintenanceMode'

Hi Scopus69,

It seems that you are running power shell, not operations manager command
shell, which is a snap-in to the normal power shell. Install both power shell
and ops mgr command shell. Then make sure you start ops mgr command shell
when you want to run the script.

Anders,

Thanks for the quick response. I have a few follow up questions.

> Is Operations Manager Command Shell installed by default on the SCOM 2007 Server?

> Should this script be running on the local Server that I am monitoring or on the SCOM 2007 server?

> How do you access this Operations Manager Command Shell?

Hi Scopus69,

The ops Mgr command shell is not installed by default, you have to select
it during the setup wizard. The script should be run on the managemnet server.
