I had a question asked about how to determine whether or not a connected volume to a Windows Server host is thin provisioned or not. I put together the below PowerShell script to Check Provisioning Type:
- Retrieve the locally connected volumes. Since this is using Get-WMIObject this is usable across all versions of Windows Server supported by Pure Storage.
- Connect to the FlashArray and retrieve volumes.
- Compare the UniqueId of the locally connected volumes to the FlashArray volume serial numbers.
- Return the volume name which has the correlated serial number.
PowerShell:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
# Get connected volumes to host $UniqueIds = Get-WMIObject -Class MSFT_Disk -Namespace ‘ROOTMicrosoftWindowsStorage’ | Select-Object ProvisioningType,UniqueId,Number # Connect to FlashArray $FlashArray = New-PfaArray -EndPoint 10.21.201.57 -Credentials (Get-Credential) -IgnoreCertificateError # Retrieved Volumes $Volumes = Get-PfaVolumes -Array $FlashArray | Select-Object Name,Serial # Inspect Volumes and compare to UniqueId ForEach ($UniqueId in $UniqueIds) { ForEach ($Volume in $Volumes) { If (($UniqueId.UniqueId).Substring($UniqueId.UniqueId.Length-24) -eq $Volume.Serial) { Write-Host “Volume: $($Volume.Name)” Write-Host “Serial: $($Volume.serial)” Switch ($UniqueId.ProvisioningType) { 0 { Write-Host “Type: Unknown” } 1 { Write-Host “Type: Thin” } 2 { Write-Host “Type: Fixed” } } } } } |
Example Output:
|
1 2 3 4 5 6 7 8 9 |
PS C:UsersAdministrator.MSLABDesktop> .Get–PfaVolumeType.ps1 cmdlet Get–Credential at command pipeline position 1 Supply values for the following parameters: Credential Volume: Server02–Data01 Serial: 45084F3508BF461400011CF9 Type: Thin |
I will be adding this as a cmdlet to the PowerShell Toolkit.
