change SCOM agent assignement to other SCOM gateway

22. June 2020 by Burkard Josh

if you need to change the assignement of a SCOM gateway to another SCOM gateway, you can do this by this script:

<#
    .SYNOPSIS
        This script sets a new Management Point for a SCOM Agent

    .PARAMETER ManagementPoint
        defines the Management Point or Gateway to use

    .PARAMETER ManagementGroup
        defines the Management Group to use

    .EXAMPLE
        Set-ScomManagementPoint.ps1 -ManagementPoint 'gateway.domain.net' -ManagementGroup 'MG001'
#>
Param (
    [string]$ManagementPoint
    ,
    [string]$ManagementGroup = 'MG001'
)
try {
    $SCOMAgent = New-Object -ComObject AgentConfigManager.MgmtSvcCfg
}
catch {
    Write-Output "no SCOM Agent found"
}
if ( -not ( [string]::IsNullOrEmpty( $SCOMAgent ) ) ) {
    Stop-Service -Name HealthService

    $StateDirectory = Get-ItemPropertyValue -Path HKLM:\SYSTEM\CurrentControlSet\services\HealthService\Parameters -Name 'State Directory'

    $CurrentMGs = $SCOMAgent.GetManagementGroups()
    foreach ( $CurrentMG in $CurrentMGs ) {
        try {
            $SCOMAgent.RemoveManagementGroup( $CurrentMG.managementGroupName )
        }
        catch {
            throw "couldn't remove current Management Group '$( $CurrentMG.managementGroupName )'"
        }
    }

    $ChildItems = Get-ChildItem -Path $StateDirectory
    foreach ( $ChildItem in $ChildItems ){
        try {
            Remove-Item -Recurse -Force -Confirm:$false -Path $ChildItem.FullName
        }
        catch {
            throw "couldn't remove '$( $ChildItem.FullName )'"
        }
    }

    $SCOMAgent.AddManagementGroup($ManagementGroup, $ManagementPoint, 5723)

    $SCOMAgent.ReloadConfiguration()

    $MGs = $SCOMAgent.GetManagementGroups()
    foreach ( $MG in $MGs ) {
        Write-Output "$( $MG.managementGroupName ):$( $MG.ManagementServer )"
    }
}

foreach ( $MG in $MGs ) {

Write-Output "$( $MG.managementGroupName ):$( $MG.ManagementServer )"

}

please note, that this script will remove the old assignement and clean up the state directory. if you don’t cleanup the state directory, the agent will after a service restart be assigned again to the old gateway.

remove sensitive files from GIT

7. May 2020 by Burkard Josh

sometimes you need to remove a file from GIT. when it contains sensitive datas like passwords, it needs to be removed from the GIT history to:

this commands helped me to do this:

git filter-branch --force --index-filter "git rm --cached -f -r --ignore-unmatch Source/accounts.csv" --tag-name-filter cat -- --all
git push --force

1 2	git filter-branch --force --index-filter "git rm --cached -f -r --ignore-unmatch Source/accounts.csv" --tag-name-filter cat -- --all git push --force

Windows Azure Pack doesn’t show Automation dashboard after updating SMA

21. February 202020. February 2020 by Burkard Josh

this days, I updated Service Management Automation (SMA) in our production environment from version 2016 UR7 to version 2019.

after the update, I had an issue with Windows Azure Pack, which couldn’t display the dashboard for the Automation provider.

after some research, i found out, that the root cause was some months earlier. we have a lot of concurrent jobs running and some times the SMA workers was overloaded and all new jobs where hanging in the queue. the solution I found on some other websites, was to mark this queued jobs as failed inside the database and then restart the worker service:

USE SMA

-- New Jobs
UPDATE [Core].[Jobs] SET StatusID=5 WHERE StatusID=1

-- Running Jobs
UPDATE [Core].[Jobs] SET StatusID=5 WHERE StatusID=3

-- Suspended Jobs
UPDATE [Core].[Jobs] SET StatusID=5 WHERE StatusID=8

USE SMA

-- New Jobs

UPDATE [Core].[Jobs] SET StatusID=5 WHERE StatusID=1

-- Running Jobs

UPDATE [Core].[Jobs] SET StatusID=5 WHERE StatusID=3

-- Suspended Jobs

UPDATE [Core].[Jobs] SET StatusID=5 WHERE StatusID=8

after setting this jobs to failed state, I had to configure the Runbook worker to start only one Runbook per Sandbox process in the file C:\Program Files\Microsoft System Center\Service Management Automation\Orchestrator.Settings.config:

<add key="MaxRunningJobs" value="1"/>
<add key="TotalAllowedJobs" value="1"/>

1 2	<add key="MaxRunningJobs" value="1"/> <add key="TotalAllowedJobs" value="1"/>

the Runbook worker could now be restarted and was working properly again. Stability was much better, than before. read more

getting Security Scopes of SCCM folder

7. February 2020 by Burkard Josh

since version 1906 SCCM supports role-based access control (RBAC) for folders. This can be configured trough the SCCM console or (recommended) PowerShell.

unfortunattely the current version of the commandlet Get-CMObjectSecurityScope doesn’t support any folder as InputObject. so, if you want to know, which Security Scope is allowed to see a folder, you have to use this:

$PathName = 'LAB:\DeviceCollection\FolderName\SubFolder' 
$Folder = Get-Item $PathName 
Get-WmiObject -ComputerName $SiteServer -Namespace "root\sms\site_$( $SiteCode )" -Query "SELECT * FROM SMS_SecuredCategoryMembership WHERE ObjectKey = '$( $Folder.ContainerNodeID )'" | ForEach-Object { Get-CMSecurityScope -Id $_.CategoryID }

$PathName = 'LAB:\DeviceCollection\FolderName\SubFolder'

$Folder = Get-Item $PathName

Get-WmiObject -ComputerName $SiteServer -Namespace "root\sms\site_$( $SiteCode )" -Query "SELECT * FROM SMS_SecuredCategoryMembership WHERE ObjectKey = '$( $Folder.ContainerNodeID )'" | ForEach-Object { Get-CMSecurityScope -Id $_.CategoryID }

to add or remove any SecurityScopes to a Folder, you can use this build-in commandlets:

Add-CMObjectSecurityScope -InputObject $Folder -Name $SecurityScopeName
Remove-CMObjectSecurityScope -InputObject $Folder -Name $SecurityScopeName

1 2	Add-CMObjectSecurityScope -InputObject $Folder -Name $SecurityScopeName Remove-CMObjectSecurityScope -InputObject $Folder -Name $SecurityScopeName

Pester tests for PowerShell modules

21. August 201919. August 2019 by Burkard Josh

if you write regularly PowerShell modules, you have to test the functions in it.

i wrote some Pester tests, which are doing this tests for all functions in a PowerShell module:

the function has SYNOPSIS, DESCRIPTION and EXAMPLES

the function has cmdletbinding

the function has an OutputType defined

the function name starts with an approved verb

the function name has an common prefix

all parameters have a help text

all parameters have a type declaration

all variables inside the function has the same upper/lower case

pass parameter values to Invoke-CMScript

22. June 202030. July 2019 by Burkard Josh

The Invoke-CMScript cmdlet invokes a PowerShell script in Microsoft System Center Configuration Manager. System Center Configuration Manager has an integrated ability to run Powershell scripts. The scripts simplify building custom tools to administer software and let you accomplish mundane tasks quickly, allowing you to get large jobs done more easily and more consistently. For more information, see Create and run PowerShell scripts from the Configuration Manager console.

unfortunately the Invoke-CMScript doesn’t allow to pass values to defined script params. if you want to do this, you have to invoke the script through the Configuration Manager console. read more

PowerShell and PSHTML in Azure Function App

10. June 201910. June 2019 by Burkard Josh

PowerShell is now available in Azure Function App (still in preview).

you can create a Powershell Function App like this:

using PowerShell modules

currently, you can’t install a powershell module inside Azure Function App, but you can upload your module to the script directory and access it from there. to do this, use Kudu:

browse to site / wwwroot:

then you can drag and drop your module ZIP-file to the right part of the explorer

the file will be uploaded and unpacked automatically

now you can reference this module directly from your function script read more

getting info about users password expiration

14. November 201814. November 2018 by Burkard Josh

i work in a multi domain environment. each domain has different password expiration rules. unfortunattely there is no notification system for the password expiration, so i have to check manually how long my passwords are valid.

for this, i wrote this PowerShell function, which does work without the use of any additional module:

reclaime diskspace on zero detection storage when deletening vmware vm

22. October 2018 by Burkard Josh

some time ago, i had the problem that my 3Par storage was getting full. in this time i removed a lot of test vm’s from this storage, but nothing happens. the storage was still full. the reason was the mechanisme how vmware deletes files from a DataStore and the activated zero-detection feature on the storage. if you delete a virtual disk file on the vmware datastore, it will only marked as deleted, but the datas are still there in the same format. to get the storage’s zero detection work, we have to zero out the deleted part of the datastore manually.

you can do this with this script:

$vCenterName   = "vcenter.domain.fqdn"
$vCenterCreds  = New-Object System.Management.Automation.PSCredential ( "username", ( ConvertTo-SecureString "PlainTextPassword" -AsPlainText -Force ) )

& 'C:\Program Files (x86)\VMware\Infrastructure\vSphere PowerCLI\Scripts\Initialize-PowerCLIEnvironment.ps1'

Connect-VIServer -Server $vCenterName -Credential $vCenterCreds -WarningAction SilentlyContinue
Set-PowerCLIConfiguration -Scope Session -WebOperationTimeoutSeconds -1  -Confirm:$false

$VMHost = ( Get-VMHost )[0]
$EsxCli = Get-EsxCli -VMHost $VMHost.Name

$Datastores = $VMHost | Get-Datastore

foreach ( $Datastore in ( $Datastores | Sort-Object Name ) )
{
    Write-Output $Datastore.Name
    $res = $EsxCli.storage.vmfs.unmap(200, $Datastore.Name, $null)
    Write-Output "   $( $res )"
}

Disconnect-VIServer -confirm:$false

Get-Module | Remove-Module -Force

$vCenterName = "vcenter.domain.fqdn"

$vCenterCreds = New-Object System.Management.Automation.PSCredential ( "username", ( ConvertTo-SecureString "PlainTextPassword" -AsPlainText -Force ) )

& 'C:\Program Files (x86)\VMware\Infrastructure\vSphere PowerCLI\Scripts\Initialize-PowerCLIEnvironment.ps1'

Connect-VIServer -Server $vCenterName -Credential $vCenterCreds -WarningAction SilentlyContinue

Set-PowerCLIConfiguration -Scope Session -WebOperationTimeoutSeconds -1 -Confirm:$false

$VMHost = ( Get-VMHost )[0]

$EsxCli = Get-EsxCli -VMHost $VMHost.Name

$Datastores = $VMHost | Get-Datastore

foreach ( $Datastore in ( $Datastores | Sort-Object Name ) )

{

Write-Output $Datastore.Name

$res = $EsxCli.storage.vmfs.unmap(200, $Datastore.Name, $null)

Write-Output " $( $res )"

}

how to get the correct Virtual Disk for a VMware vm

8. March 20188. March 2017 by Burkard Josh

Some times I have the problem, I need to resize or delete a VMware virtual disk, but I only know the guest’s drive letter. In vm’s where there are only one virtual disk, or where each virtual disk has a different size, this isn’t a problem. but if you have a vm with multiple virtual disk with exactly the same size, you can’t compare it between the guest Disk Manager and the virtual disk sizes. if your vm has more than one SCSI controller, the problem will increase.

Windows Disk Manager	VMware VM settings

I searched long time to solve this problem, but I couldn’t find an easy solution for this. so I wrote this PowerShell script:

<#
.SYNOPSIS
    This script will return informations about virtual disks and windows disk allocation

.DESCRIPTION
    This script will return informations about virtual disks and windows disk allocation

.PARAMETER vCenterName
    defines the fqdn of the vCenter

.PARAMETER vmName
    defines the name of the vm (like naming in vCenter, not the fqdn / dns name)

.PARAMETER vmCred
    enter credentials to connect to the guest vm

.EXAMPLE
    $vmCred = New-Object System.Management.Automation.PSCredential ('domain\username', ( ConvertTo-SecureString 'YourSecretPassword' -AsPlainText -Force ) )
    .\ALL-OPR-get-VMDiskInfos.ps1 -vCenterName 'vcenter.domain.local' -vmName 'VMName' -vmcred $vmCred
