On a previous post I showed off a little PowerShell script that I've written to build my SolarWinds Orion Servers.  That post left us with a freshly imaged Windows Server.  Like I said before, you can install the O/S however you like.  I used Windows Deployment Services because I'm comfortable with it.


I used Windows Server 2016 because this is my lab and...



Now I've got a list of things that I want to do to this machine.

  1. Bring the Disks Online & Initialize
  2. Format Disks & Disable Indexing
  3. Configure the Page File
  4. Import the Certificate for SSL (Optional)


Because I'm me, I do this with PowerShell.  I'm going to go through each of stage one by one.

Stage 0: Declare Variables

I don't list this because this is something that I have in every script.  Before I even get into this, I need to define my variables.  For this it's disk names and drive letters.

#region Build Disk List
$DiskInfo  = @()
$DiskInfo += New-Object -TypeName PSObject -Property ( [ordered]@{ DiskNumber = [int]1; DriveLetter = "D"; Label = "Page File" } )
$DiskInfo += New-Object -TypeName PSObject -Property ( [ordered]@{ DiskNumber = [int]2; DriveLetter = "E"; Label = "Programs" } )
$DiskInfo += New-Object -TypeName PSObject -Property ( [ordered]@{ DiskNumber = [int]3; DriveLetter = "F"; Label = "Web" } )
$DiskInfo += New-Object -TypeName PSObject -Property ( [ordered]@{ DiskNumber = [int]4; DriveLetter = "G"; Label = "Logs" } )


This looks simple, because it is.  It's simply a list of the disk numbers, the drive letter, and the labels that I want to use for the additional drives.

Stage 1: Bring the Disks Online & Initialize

Since I need to bring all offline disks online and choose a partition type (GPT), I can do this all at once.

#region Online & Enable RAW disks
Get-Disk | Where-Object { $_.OperationalStatus -eq "Offline" } | Set-Disk -IsOffline:$false
Get-Disk | Where-Object { $_.PartitionStyle -eq "RAW" } | ForEach-Object { Initialize-Disk -Number $_.Number -PartitionStyle GPT }


Stage 2: Format Disks & Disable Indexing

This is where I really use the variables that are declared in Stage 0.  I do this with a ForEach Loop.

#region Create Partitions & Format
$FullFormat = $false # indicates a "quick" format
ForEach ( $Disk in $DiskInfo )
    # Create Partition and then Format it
    New-Partition -DiskNumber $Disk.DiskNumber -UseMaximumSize -DriveLetter $Disk.DriveLetter | Out-Null
    Format-Volume -DriveLetter $Disk.DriveLetter -FileSystem NTFS -AllocationUnitSize 64KB -Force -Confirm:$false -Full:$FullFormat -NewFileSystemLabel $Disk.Label
    # Disable Indexing via WMI
    $WmiVolume = Get-WmiObject -Query "SELECT * FROM Win32_Volume WHERE DriveLetter = '$( $Disk.DriveLetter ):'"
    $WmiVolume.IndexingEnabled = $false


We're getting closer!  Now we've got this:



Stage 3: Configure the Page File

Getting the "best practices" for page files are crazy and all over the board.  Are you using flash storage?  Do you keep it on the O/S disk?  Do you declare a fixed size?  I decided to fall back on settings that I've used for years.

Page file does not live on the O/S disk.

Page file is statically set

Page file is RAM size + 257MB

In script form, this looks something like this:

#region Set Page Files
$CompSys = Get-WmiObject -Class Win32_ComputerSystem -EnableAllPrivileges
# is the system set to use system managed page files
if ( $CompSys.AutomaticManagedPagefile )
    # if so, turn it off
    $CompSys.AutomaticManagedPagefile = $false
# Set the size to 16GB + 257MB (per Microsoft Recommendations) and move it to the D:\ Drive
# as a safety-net I also keep 8GB on the C:\ Drive.
$PageFileSettings = @()
$PageFileSettings += "c:\pagefile.sys 8192 8192"
$PageFileSettings += "d:\pagefile.sys 16641 16641"
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\" -Name "pagingfiles" -Type multistring -Value $PageFileSettings


Stage 4: Import the Certificate for SSL (Optional)

Since this is my lab, I get to do what I want.  (See above)  I include using SSL for Orion.  I have a wildcard certificate that I can use within my lab, so if I import it, then I can enable SSL when the configuration wizard runs.  This certificate is saved on a DFS share in my lab.  This is the script to import it.

#region Import Certificate
# Lastly, import my internal PKI Certificate for use with HTTPS
$CertName = "WildcardCert_demo.lab"
$CertPath = "\\Demo.Lab\Files\Data\Certificates\"
$PfxFile = Get-ChildItem -Path $CertPath -Filter "$CertName.pfx"
$PfxPass = ConvertTo-SecureString -String ( Get-ChildItem -Path $CertPath -Filter "$CertName.password.txt" | Get-Content -Raw ) -AsPlainText -Force
Import-PfxCertificate -FilePath $PfxFile.FullName -Password $PfxPass


That's it.  Now the disks are setup, the page file is set, and the certificate is installed.  Next, I rename the computer, reboot, run Windows Updates, reboot, run Windows Updates, reboot, run Windows Updates... (you see where this is going, right?)


Execution Time: 16 seconds

Time saved: at least 15 minutes.


There's still some prep work I can do via scripting and I'll provide that next.
