This is another way of putting SCOM Agents in maintenance mode.
I faced a problem with the earlier management pack wherein there was a rule running against the management servers. You can take a look at this approach in my earlier posts.
Whenever the rule failed to load, the agents failed to get in maintenance mode. This approach also takes into consideration the SCOM servers not being put in maintenance mode.
In the current approach I use the command notification channel together with the management pack rule for alerting on sccm reboot events and putting the agents in maintenance mode.
- Create an alert in SCOM when a computer is rebooted by SCCM
- Run a powershell script using command notifications channel to put the computer in maintenance mode.
Create a new Command notification channel in SCOM
The text in the screenshot is below.
Path for command file:
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
Command line parameters:
"c:\ScomScripts\StartMaintenanceMode.ps1" "-computer" "$Data/Context/DataItem/ManagedEntityDisplayName$"
Startup folder:
C:\Windows\System32\WindowsPowerShell\v1.0
Script:
Create a folder in your SCOM server and name it SCOMScripts.
Add the following script in that folder. Be sure to add your SCOM server names in the script.
param([string] $Computer)
Function Out($data)
{
Out-File -FilePath C:\SCOMScripts\MaintenanceModeOutput.txt -InputObject $data -Append
}
$data = "Starting maintenance mode Script" + "`t" + $(get-date).ToString()
Out $data
$data = $Computer + " was rebooted"
Out $data
## Start Maintenance mode on Computers which are rebooted by ConfigMgr
Function WriteEvent ($Messages,$ID) { $Messages = $Messages + "`t" + $(get-date).ToString()
Write-EventLog -LogName Application -Source PatchingSuppress -EventId $ID -Message $Messages }
if($Computer -notmatch "yourscomservername")
{
try {
WriteEvent "Starting MaintenanceMode script for $Computer" "1237"
Import-Module OperationsManager
$Instance = Get-SCOMClassInstance -Name $Computer
$Time = ((Get-Date).AddMinutes(15))
Start-SCOMMaintenanceMode -Instance $Instance -EndTime $Time -Reason "PlannedApplicationMaintenance" -Comment "Applying software update."
WriteEvent "Ending MaintenanceMode script" "1238"
}
catch
{
$_.exception
Out $_.exception.message
}
}
else
{
Out "This was a management server $computer"
}
The management pack for creating the event is below.
