In my article for the Provisioning Services (PVS) 4.12 script, I stated “There are two items I have yet to find in the PVS PowerShell Programmers Guide: Boot production devices from version and which version is the current booting version (the one with the green checkmark)”.  Thankfully a member of the Citrix Provisioning Services team reached out to offer help.  This article explains how the missing items were implemented.

It turns out the property used for the Access column is also used to determine the Boot production devices from version and is part of the puzzle for the current booting version.

The logic goes like this:

Any vDisk that has access property value of “Override” (access=3) is what is used for both Boot production devices from version and is the current booting version since it was manually selected.

Otherwise, the vDisk with the highest version number is the current booting version IF the IsPending property is False (IsPending=0).

I asked programming super genius Remko Weijnen for help and he told me to use Where-Object and Measure-Object but neither of those worked with the vomit inducing PVS “PowerShell” implementation.

Here is the code I created to see if the booting version was manually selected and what the highest version number with IsPending of False.

#get the current booting version
#by default, the $DiskVersions object is in version number order lowest to highest
#the initial or base version is 0 and always exists
[string]$BootingVersion = "0"
[bool]$BootOverride = $False
ForEach($DiskVersion in $DiskVersions)
{
	If($DiskVersion.access -eq "3")
	{
		#override i.e. manually selected boot version
		$BootingVersion = $DiskVersion.version
		$BootOverride = $True
		Break
	}
	ElseIf($DiskVersion.access -eq "0" -and $DiskVersion.IsPending -eq "0" )
	{
		$BootingVersion = $DiskVersion.version
		$BootOverride = $False
	}
}

I then added a few lines to show the Boot production devices from version and also which vDisk version id the current booting version).

WriteWordLine 0 2 "Boot production devices from version`t: " -NoNewLine
If($BootOverride)
{
	WriteWordLine 0 0 $BootingVersion
}
Else
{
	WriteWordLine 0 0 "Newest released"
}
WriteWordLine 0 0 ""

<snip>

WriteWordLine 0 2 "Version`t`t`t`t`t: " -NoNewLine
If($DiskVersion.version -eq $BootingVersion)
{
	WriteWordLine 0 0 "$($DiskVersion.version) (Current booting version)"
}
Else
{
	WriteWordLine 0 0 $DiskVersion.version
}

To test I first used the defaults.

Here is the output from my report.

Then I manually selected a version for booting.

Here is the output from my report.

Script version is now 4.13. And Shane Kleinert should now have all his vDisk Versions information he asked for.

NOTE: This script is continually updated. You can always find the most current version by going to https://carlwebster.com/where-to-get-copies-of-the-documentation-scripts/
