Powershell: Update Distribution Priority for all Task Sequence Packages

Last week we had a most unfortunate incident. One of our domains we managed had 4 of the 5 drives fail in the SCCM Primary’s Disk Array. This domain fed off of our Packages from our SCCM 2007 environment. While most of the OSD media was created at the Central Site, the Task Sequence and Boot media were created and managed on this domain and on this SCCM Primary Server–Pretty much a total loss.

After the hardware was fixed, we updated the site to SCCM 2012 R2 and began rebuilding the OSD process. Since this new SCCM 2012 site needed to replicate content again, the multitude of packages began distributing. During the outage PC Deployments got behind so we needed a quick way to set the priority of all (50 or so) packages to “high” priority so they would distribute first. Rather than going through each package 1-by-1, I knew Powershell could do this quicker than I could 2 packages manually!

A few Cmdlets to familiarize ourselves with:

  • Get-CMTaskSequence – Gets a Config Manager Task Sequence
  • Get-CMPackage – Gets a Config Manager “Classic” Package
  • Get-CMDriverPackage – Gets a Config Manager Driver Package
  • Get-CMOperatingSystemImage – Gets a Config Manager Operating System Image (Not source media)
  • Get-CMBootImage – Gets a Config Manager Boot Image
  • Get-CMOperatingSystemInstaller – Gets a Config Manager Operating System Source Media Package

First thing is to get the Referenced Task Sequence Packages. This can be done with a quick one liner:

(Get-CMTaskSequence -TaskSequencePackageId AAA######).References.Package

From here we have packages to feed into other cmdlets and modify the priority. But there’s one catch…Depending on the type of package (OSImage, Package, Boot Media, Driver Package, etc…) a different cmdlet is required. To work around this, I went to SQL; while i realize this isn’t a *great* workaround, it does the job.

The following SQL Query can be used to easily get the appropriate Package Type:

[System.Data.SqlClient.SqlConnection]$sms = New-Object System.Data.SqlClient.SqlConnection("Data Source=$SqlServerName;Integrated Security=SSPI;Initial Catalog=$SqlTableName")
        [System.Data.SqlClient.SqlCommand]$qry = New-Object System.Data.SqlClient.SqlCommand("SELECT PackageID, Name, PackageType FROM v_package WHERE PackageID = '$packageId'", $sms)
        [System.Data.SqlClient.SqlDataReader]$res = $qry.ExecuteReader()

        while ($res.Read() -eq $true)
            $tmp = @{}
            for ($i=0;$i -lt $res.FieldCount; $i++) {
                $tmp[$res.GetName($i)] = $res.GetValue($i)
            $output += $tmp
            Write-Host "SQL Connection / Query Failed:`n$_"

This will return the results into a very nice object to work with: “$output” in this case. Grabbing a column is easy as well: $output.<columnName> ($output.PackageType).

From here we do a switch statement on the “PackageType” value and update the priority. Free Samples:

Standard Package:

$pkg = Get-CMPackage -Id  -ErrorAction SilentlyContinue
$pkg.Priority = 1 #Set to High Priority
Set-CMPackage -InputObject $pkg -ErrorAction SilentlyContinue

Driver Package

$dp = Get-CMDriverPackage -ID $p -ErrorAction SilentlyContinue
$dp.Priority = 1  #Set to High Priority
Set-CMDriverPackage -InputObject $dp -ErrorAction SilentlyContinue

OS Image Package

$osp = Get-CMOperatingSystemImage -Id $p -ErrorAction SilentlyContinue
$osp.Priority = 1  #Set to High Priority
Set-CMOperatingSystemImage -InputObject $osp -ErrorAction SilentlyContinue

Boot Image Package

$bi = Get-CMBootImage -Id $p -ErrorAction SilentlyContinue
$bi.Priority = 1  #Set to High Priority
Set-CMBootImage -InputObject $bi -ErrorAction SilentlyContinue

Operating System Install Package

$osi = Get-CMOperatingSystemInstaller -Id $p -ErrorAction SilentlyContinue
$osi.Priority = 1  #Set to High Priority
Set-CMOperatingSystemInstaller -InputObject $osi -ErrorAction SilentlyContinue

…And that’s just about the basics of it. After using this script to set all of this up, I expanded to allow either a Task Sequence Package ID or an array of Package ID’s. There are some required items including Read Access to your Config Manager Sql Database, and the 2012R2 console has to be installed on the computer (to use the cmdlets).
