Hi All,

I am trying to place multiple servers in Maintenance Mode in SCOM 2012 but i could not find any PoSh script or any other solution to do it.

Could someone help me please?

Regards, Srini

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")
                                }
                                }
                }

This could be done from SCOM console. from under Monitoring --> windows computer.

Right click , maintenance mode and start Maintenance mode.

Hi Sridhar,

It does not work.

I opened a PS session and connected to the management group using

New-SCOMManagementgroupconnection -computername abc.com

and tried to run the script but it failed with errors.

new-object : Retrieving the COM class factory for component with CLSID {00000000-0000-0000-0000-000000000000} failed
due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

Any Suggestion??

Thanks.

Hi,

I use this tool from Tim Mcfadden:

SCOM 2012 Maintenance Mode Scheduler

Hi Agarwal,

I need to place hundreds of servers in MM so doing it from console is not the easiest option.

Thanks

Hi,

Thanks for sharing the link. I hope it addresses my requirement.

Will go through it.

Thanks Xin.

It addressed my requirements just perfect.

I have added few cluster servers in that group as well so I believe it would also be put in to maintenance mode and don't throw any alerts, right?
