How to determine storage type (SAN/NAS/local disk) remotely, using PowerShell? - powershell

Question

I have to collect the attached storage types of each server in our environment: Several hundreds of W2K3/W2K8 servers.
A script would be very useful to determine if the attached storage is SAN / SAN mirrored / NAS / local or combination of these. The problem is that I haven't really found any good solution.
I was thinking about a script, and the best I could figure out would do something like the following:
If the server uses SAN, Veritas Storage Foundation is always installed, so I would search for it with gwmi win32_product. This is really slow, and this doesn't provide the information if the storage is SAN, or SAN mirrored.
If the attached storage is NAS, there must be an ISCSI target ip, and I would search for that somehow.
I really don't think these methods are acceptable though. Could you please help me find a better way to determine the attached storage types somehow?
Thank you very much

I found an article about accessing the VDS service in powershell. Getting More Information About You Cluster LUN’s
Massaged the code a bit to get type. Works even on 2003.
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Storage.Vds") | Out-Null
$oVdsServiceLoader = New-Object Microsoft.Storage.Vds.ServiceLoader
$oVdsService = $oVdsServiceLoader.LoadService($null)
$oVdsService.WaitForServiceReady()
$oVdsService.Reenumerate()
$cDisks = ($oVdsService.Providers |% {$_.Packs}) |% {$_.Disks}
$cPacks = $oVdsService.Providers |% {$_.Packs}
foreach($oPack in $cPacks)
{
If($oPack.Status -eq "Online")
{
foreach($oDisk in $oPack.Disks)
{
Write-Host "$($oDisk.FriendlyName) ( $($oDisk.BusType) )"
}
foreach($oVolume in $oPack.Volumes)
{
Write-Host "`t$($oVolume.AccessPaths) ( $($oVolume.Label) )"
}
}
}

You could probably find the info in one of the following WMI classes:
Win32_LogicalDisk
http://msdn.microsoft.com/en-us/library/windows/desktop/aa394173(v=vs.85).aspx
Win32_Volume
http://msdn.microsoft.com/en-us/library/windows/desktop/aa394515(v=vs.85).aspx
Win32_DiskDrive
http://msdn.microsoft.com/en-us/library/windows/desktop/aa394132(v=vs.85).aspx
Then... do something like:
Get-AdComputer Server* | Foreach-Object { Get-WmiObject -Class Win32_DiskDrive -ComputerName $_.Name }
