Powershell script to stop system maintenance mode

In the event you want to pull the computer out of maintenance mode for some reason, here is the script for ending the maintenance mode. The command line prompts could be hard coded as variables or you could add a $params statement to the front of the script to feed in a variable.

$RMSFQDN = Read-Host "Enter the FQDN of your management server"

$Name = "Microsoft.EnterpriseManagement.OperationsManager.Client"

$ModuleLoaded = Get-Pssnapin $Name -ErrorAction SilentlyContinue

If (-not $ModuleLoaded)
{
add-pssnapin "Microsoft.EnterpriseManagement.OperationsManager.Client";
}

New-ManagementGroupConnection -ConnectionString $RMSFQDN
Set-Location "OperationsManagerMonitoring::";

$computerClass = get-monitoringclass -name:Microsoft.SystemCenter.ManagedComputer
$computerPrincipalName = Read-Host "Enter the FQDN computer name for ending maintenance:"
$computerCriteria = "PrincipalName='" + $computerPrincipalName + "'"
$computer = get-monitoringobject -monitoringclass:$computerClass -criteria:$computerCriteria


if($computer -eq $null)
{
$unixClass = get-monitoringclass -name "Microsoft.Unix.Computer"
$monObject = Get-MonitoringObject -monitoringclass:$unixClass
$computer = $monObject | where {$_.displayname -eq $computerPrincipalName}
}
ELSE
{
$computerClass = get-monitoringclass -name:Microsoft.Windows.Computer
$computer = get-monitoringobject -monitoringclass:$computerClass -criteria:$computerCriteria
}


if($computer.InMaintenanceMode -eq $true)
{
"Stopping maintenance mode for: " + $computerPrincipalName
$computer.StopMaintenanceMode([DateTime]::Now.ToUniversalTime(),[Microsoft.EnterpriseManagement.Common.TraversalDepth]::Recursive);
}
ELSE
{
"The computer " + $computerPrincipalName + " is not in maintenance mode."
}

Comprehensive Powershell Script for System Maintenance Mode

The script I posted yesterday was a quick and dirty script to put a windows host into maintenance mode. Problem is, that script doesn't work on agentless systems or Linux/Unix, so I took care of that. The following script will work for windows hosts, agentless hosts and linux/unix. The caveat is you have to enter the fully qualified domain name of the host. Alternatively, you could alter the script to append your DNS suffix to the host name to save some key strokes. Enjoy!

$RMSFQDN = Read-Host "Enter the FQDN of your Management Server"
$Name = "Microsoft.EnterpriseManagement.OperationsManager.Client"

$ModuleLoaded = Get-Pssnapin $Name -ErrorAction SilentlyContinue

If (-not $ModuleLoaded)
{
add-pssnapin "Microsoft.EnterpriseManagement.OperationsManager.Client";
}

New-ManagementGroupConnection -ConnectionString $RMSFQDN
Set-Location "OperationsManagerMonitoring::";

$startTime = [System.DateTime]::Now
$Hours = Read-Host "Enter the number of hours to put into maintenance:"
$endTime = $startTime.AddHours($Hours)
$comment = "Computer Maintenance"



$computerClass = get-monitoringclass -name:Microsoft.SystemCenter.ManagedComputer
$computerPrincipalName = Read-Host "Enter the FQDN computer name"
$computerCriteria = "PrincipalName='" + $computerPrincipalName + "'"
$computer = get-monitoringobject -monitoringclass:$computerClass -criteria:$computerCriteria


if($computer -eq $null)
{
$unixClass = get-monitoringclass -name "Microsoft.Unix.Computer"
$monObject = Get-MonitoringObject -monitoringclass:$unixClass
$computer = $monObject | where {$_.displayname -eq $computerPrincipalName}
}
ELSE
{
$computerClass = get-monitoringclass -name:Microsoft.Windows.Computer
$computer = get-monitoringobject -monitoringclass:$computerClass -criteria:$computerCriteria
}

if($computer.InMaintenanceMode -eq $false)
{
"Putting " + $computerPrincipalName + " into maintenance mode"
New-MaintenanceWindow -startTime:$startTime -endTime:$endTime -comment:$comment -monitoringObject:$computer
}

Scripting the Maintenance Window for a System through Powershell

Enclosed is a powershell script I put together from a number of examples out there. I ran into some overly complex scripts or ones that didn't quite work right when trying to find something quick and easy to use.

Ultimately, in our environment, I hard coded many of the variables to make the process quick and easy (Basically everything but the computer name). For the purposes of this script, it prompts for everything but the time window. I have removed the comments for the time being until I can get it to show up nicely in the blog.

$RMSFQDN = Read-Host "Please enter the FQDN of your management server:"
add-pssnapin "Microsoft.EnterpriseManagement.OperationsManager.Client";
New-ManagementGroupConnection -ConnectionString $RMSFQDN
Set-Location "OperationsManagerMonitoring::";

$startTime = [System.DateTime]::Now

$Hours = 1

$endTime = $startTime.AddHours($Hours)

$strComputerName = Read-Host "Enter the computer name to be put into maintenance mode:"

$objComputer = Get-Agent | Where-Object {$_.Name -match $strComputerName}

$comment = Read-host "Please provide a comment for putting the system in maintenance mode:"

$objComputer.HostComputer | New-MaintenanceWindow -StartTime:$startTime -EndTime:$endTime -Comment:$Comment
