Using VMware seriously requires a lot of (shared) storage. This kind of storage (on a SAN for instance) is quite expensive. So you might want to check if you are wasting a lot of this space. When you look at the storage in VMware, it consists of multiple abstraction layers. A virtual machine has one or more Logical Disks, which are indicated by driveletters. You can use WMI to determine the amount of used and free space (Win32_LogicalDisk). One or more logical disks are contained in a partition. One or more partitions reside on a physical disk. That physical disk is really a virtual disk, a vmdk file to be precise. One or more vmdk files reside in a Datastore, which can be found on a LUN on your SAN.
The following script enumerates most of these layers (from logical disk to datastore) and calculates the used and free space. The final line exports the results to a csv file for use in Excel. And the script also helps you to calculate the average free space by showing the totals without the duplicates (don’t try to average the averages in excel, that’s not accurate because datastores contain duplicates and averages should be weighed).
UPDATE: I have modified the script, so no more matching of disks is done based on disk size. The match is made based on SCSI IDs and WMI relations. Thanks to adavidm on the VI Toolkit Community

Hi Hugo,
I got an error on this one, something to do with the “-f” any ideas?
Error formatting a string: Input string was not in a correct format..

Dear Hugo!
Very nice script! I have the following problem:
I would like to have a script which sents my an alarm by email if a LUN has for example only 15% of free space.
Could you write anything like that?
That would be very nice and I think a lot of VI3 admins need that.
Greetings
Simon
@JoeL
I think you might have a datastore with special characters in it. You can try to avoid the problem by using:
$DatastoreName = $Datastore.Name
Write-Progress “Gathering Info” “Processing $DatastoreName” -Id 0
Clear-Variable $DatastoreName -ErrorAction SilentlyContinue
Let me know if that helps.
Hugo
@Simon
Try this:
$VCServerName = “MYVCSERVER”
$Decimals = 0
$Limit = 15
$From = “no@spam.mow”
$To = “SomeOne@Foo.com”
$Title = “Datastore nearly full!”
$VC = Connect-VIServer $VCServerName
$Datastores = Get-Datastore
ForEach ($Datastore in $Datastores)
{
$PercentFree = [math]::Round(((100*($Datastore.FreeSpaceMB / $Datastore.CapacityMB )),$Decimals)
If ($PercentFree -lt $Limit)
{
$Body = “Datastore {0} has {1} percent free space.” -f $Datastore.Name, $PercentFree

$SmtpClient.host = $SmtpServer
}
}
When I run this script, I got the following error, can you check that?

@Jack
That’s a Windows / Networking issue. You cannot reach that server through RPC (Remote Procedure Call). Check network connectivity and possibly DCOM permissions. Lots of info on Google.
Hope that helps you out.
Hugo
Nice script, and just a couple of comments.
To get around the non-connectivity errors – this script could be modified to do this via sql, since VirtualCenter stores all the VM free/used/capacity, as well as Datastore free/used/capacity in a simple table structure for any client with VMtools installed.
Alternatively, we could trim the ‘dns’ name off the VMname and do a lookup to determine credentials to connect to the remote machine with a default local account. I think I will probably head down this path myself
Sometimes disks are on local VMFS volumes and you don’t want this as it will throw the stats out. It would nice to have an opt-out to exclude VMs with disks on ‘local’ storage. But this is pretty trivial.
Cheers.
Simon, Thanks so much for your comments. I’ll see what I can do to improve the script. If you want a quick improvement, check out VCPlus here: http://www.run-virtual.com/?page_id=184. It runs as a service and dumps the results in custom fields, so they are visible within the VI Client.
error :
Error formatting a string: Input string was not in a correct format..
At :line:46 char:70
+ Write-Progress “Gathering Information” (”Processing Datastore {0}” -f <<<< $Datastore.Name) -Id 0
the datastore name is quite long: “GL-dldn0534nsd-rg9-034-templates” will the script cater for that ?.
Regards
sorry – looks like i have same problem as Joel. Your extra code fixed that but now get :
Error formatting a string: Input string was not in a correct format..
At :line:65 char:65
+ Write-Progress “Gathering Information” (”Processing VMDK {0}” -f <<<< $vmdk.Path) -Id 1
$vmdk.path has a couple of “-” in it, could this be the problem ?.
What about a section to exclude certain datastores?
@Ryan
You could modify this part:
# List Datastores (Datastore Name)
Write-Progress “Gathering Information” “Listing Datastores” -Id 0
$Datastores = Get-Datastore | Sort Name
Into something like this:
# List Datastores (Datastore Name)
Write-Progress “Gathering Information” “Listing Datastores” -Id 0
$exclusions = “Datastore1″, “Datastore2″
$Datastores = Get-Datastore | Where {$exclusions -notcontains $_.Name} | Sort Name
@Simon

I stumbled across this website after a google search. I’m interested in running this script. What do I need to have installed for it to run? Can I just copy and paste into a file, what file extension does it need etc. to execute. Thanks!
@Rhodan
Hi Rhodan. You need Windows Powershell and the VI Toolkit which adds the Vmware powershell components used in the script.
Save the file as a ps1 extension, and have a search for “how to run powershell scripts” on google you should find a microsoft page by the scripting guy which will tell you what to do.
Hope this helps
Hi Hugo
Great Script
Trying to understand though why some of my VM’s would show up as “NO MATCHES!” when doing the SCSI matching. Can you explain a little about this part of the script so I can work out where it’s going wrong. I’m wondering if there are problems with my VM’s
Regards
C Stewart

I am getting the expected results for only a few VMs but most are getting this error messsage while running the script:

Eric,
The error indicates you have insufficient permissions to do a WMI query to the machines. Make sure the account running the script is local admin on all target vm’s.
I am looking to use PowerShell to run against my environment, asks me which cluster I want to investigate, and then enumerate each lun, the used space, total capacity, and free space, then dump that to a csv or xls file. Can you please advise?
Do you mean LUNs or datastores? (Subtle difference)

I have blogged about several bits and pieces you could use. There’s a Create-Listbox function I wrote, which makes selecting the cluster really nifty. Enumerating LUNs should be a breeze with the VI Toolkit 1.5 Get-SCSILun cmdlet. Capacity and free space are properties of those luns, so easily extracted.
I’ll write a script when I have some spare time. Check back soon.
OK, local admin account, not domain account. Thanks will give that a shot.
Cool Script.. How do I get the script to continue after failures because of “access denied” or “RPC errors”? and in report leave entries blank..
denied@admin
@Ainz
Try setting $errorActionPreference = SilentlyContinue
Hugo
I did try setting it.. but I get the term ‘SilentlyContinue” is not recognized as a cmdlet
Sorry, that should be:
$ErrorActionPreference = “SilentlyContinue”
(with quotes)
Hugo,
I was able to get the script to continue after failures and pipe failed VMs into a error log..
“trap {
Write-Host “error connecting to $VMRef.HosteName” -Foregroundcolor Red
“$VMRef.VM” | Out-File d:\Reports\errors.txt -append
continue
}”
Thanks..
Hi Hugo,
i tryed to run your great script against our Virtual Center.
Starting fine…. but when the script reaches a VM running Linux an exception occured and the script stopped. I know running WMI – Commands against a Linux Host doesnt work – but – i am an absulute Powershell Beginner and therefore i have no idea to “help” the script continue after the exception.
Do you have a idea to solve this?
Thanks in advance and excuse my horrible english,
Frank
Hi all,
I’ve recently had to do some work on some disk space reporting which may be of use. In terms of excluding ‘local’ datastore, the datastore view (get-datastore | get-view) contains summary.MultipleHostAccess. You can use this field, to exclude datastores that are local by ‘assuming’ that any VMFS or NFS volume that has MultipleHostAccess true, will be shared storage, and anything set to false will be local.
Working well, so far.

@admin
Hi All,
I know it’s been a bit since the last post but I have a quick question. The above script works great in my environment – really gives great info in the CSV. Is it possible to capture in that CSV what VMDK’s that the script finds that are powered off? I am very new to PowerShell – I did see that the script does know here:

That a VM is off and points to the VMDK althougth it doesn’t know who the owner of the VMDK is…can this data be stored and also added to the CSV? This is to flag to me so I know what the LUN and Datastore picture is with all VM’s on but to also know what VM’s are currently off to ensure there is enough space on the LUN/Datastore when it is turned back on…
Thanks for the great script

Okay, no problem. I do my best to keep supporting all scripts. Also plder ones.
Try replacing the Write-Host “VM powered off” bit with this:
# Create Output Object
$myObj = “” | Select Datastore, DSSizeGB, DSFreeGB, DSPercentFree, DiskFile, VM, HardDisk, DriveLetter, DiskSizeGB, DiskFreeGB, PercFree
# List datastore name
$myObj.Datastore = $Datastore.Name
# Determine datastore size in GB
$myObj.DSSizeGB = [Math]::Round(($Datastore.CapacityMB * 1MB / 1GB),$Decimals)
$myObj.DSFreeGB = [Math]::Round(($Datastore.FreeSpaceMB * 1MB / 1GB),$Decimals)
# Determine datastore free space (DS%Free)
$myObj.DSPercentFree = [Math]::Round((100*($Datastore.FreeSpaceMB/$Datastore.CapacityMB)),$Decimals)
# List disk file name
$myObj.DiskFile = $vmdk.Path
# List VM Name
$myObj.VM = $VMRef.VM
# Determine virtual hard disk / logical drive
$myObj.HardDisk = $VMRef.DiskName
# Report driveletter
$myObj.DriveLetter = “UNKNOWN: VM OFF”
# Report Size
$myObj.DiskSizeGB = “UNKNOWN: VM OFF”
# Report Free Space
$myObj.DiskFreeGB = “UNKNOWN: VM OFF”
# Calculate Percentage free space
$myObj.PercFree = “UNKNOWN: VM OFF”
Write-Host “RESULT:” -ForegroundColor “yellow”
$myObj
# Add output object to output collection
$myCol += $myObj

Thank you very much it seems to have worked as I expected. I did get a lot of errors though at the end of the script:(this is a sample there was over a page of them in the toolkit screen….)

Hi Hugo,
I’m trying to run this script in our vSphere 4 evironment but i’m getting the error:
Exception calling “SearchDatastoreSubFolders” with “2″ argument(s): “Not initialized: boolean fileOwner”
There is 1 esx 3.5 host available, connected to this host the script will run better, also with the same error, the file is present after running the script but no data inside it..
Do you have any suggestion??
Fabian
I too have tried running this on my vSphere environment and get the same error…
I am getting the following error when I ran the code above
Exception calling “SearchDataStoreSubFolders” with 2 arguments : “Permission to perform this operation was denied”
Hi,
Can you tell me how can I find out the poweroff Vm and also when it is poweroff and by whom with powershell script.
I know how to get the poweroff vm, but not able to get the other details.
If possible can you put your comments on this.
Regards
Gurjit Dhillon
Hi,
Is it possible to get all or most of the details returned by Get-WMIObject by using Get-VMguest instead? I’m trying to figure out how I can get the logical disk information without network access to the VM’s, such as in a DMZ.
Cheers
Hi Stephen,
I’m afraid that won’t work. The only disk-related information Get-VMGuest returns is a list of logical volumes and sizes. For this script, you need the relationship between the vDisks and the logical volumes.

[...] be scripted!. After a quick search in my administrators manual (google), I found a blog post from Hugo Peeters. His script uses the same WMI properties to match the Windows disk to its corresponding virtual [...]
This script is excellent and works great for my windows VM. Do you have suggestions for doing something similar to gain visibility into the disk usage by my Linux VMs?They all use LVM to manage the disk space.
Try searching the internet for linux vm invoke-psscript. That might yield some results. Good luck!
I have one for you. Im looking for a script that will list all the guests and their storage. Something that would be useful to a planning group.
I am getting an exception when running the script:
Exception calling “SearchDatastoreSubFolders” with “2″ argument(s): “Cannot contact the specified host (xxxxxxxxxxxxx). The host may not be available on the network, a network configuration problem may exist, or the management services on this host may not be responding.”
I know why I am getting the exception: the host is in Standby mode. I have a few hosts like that, ready to kick in some extra capacity if needed during heavy delevelopment cycles. The question is: is there a way to bypass the hosts that are in Standby mode (or unavailable for any reason) so that the script continues? I already added the following line $ErrorActionPreference = “SilentlyContinue”, but that does not seem to help… Any idea?
This algorithm works with vmx-04 but with the addition of the newer controllers in vmx-07 (LSI Logic SAS and Paravirtual) the offset to SCSIPort is no longer fixed at one, but can be anywhere from 0 to 3 from what I have seen. Has anyone encountered this, and if so, found a solution?
I am seeing the following error when running the scrip

Derek,
Looks like copy/paste error. I have updated the post so the formatting is better. Please try copying the script again.
Hugo
@Admin
I still get the same error. I have a small test cluster running one VM currently (I know it sound sick
). I have the rights to do get-wmiobject queries. I don’t why it is saying attempted to divide by zero. That doesn’t make any sense to me.
Do you have any other ideas?

Odd. You’re SCSI bus:target numbers appear to be off. Try replacing this line of code in the script and see whether you get a match:

Wait, my bad (again). Show me the output of the following commands:

Aha! It is only the SCSI bus ID that is off. Make this adjustment to the original script and you should get results:
Hugo
Cool it works! Thank you very much! Could you give me a short explanation what’s the difference between $_.SCSIPort – 1 and $_.SCSIPort – 2?
A disk in Windows (and probably in Linux) gets a SCSI ID in the form of x:y, where x is a number indicating the SCSI Bus i.e. controller and y is the port i.e. disk. Take a look at Edit Settings for your VM and find each disk’s SCSI ID. In your case 0:0, 0:1 and 0:2.
The script uses this ID to match the disks of your vm’s to the disk info found via WMI.
In your case, WMI lists the IDs as 2:0, 2:1 and 2:2. In my testlab it reports 1:0,1:1 and 1:2 for the same vm disks. So instead of subtracting 1 from the SCSI Bus ID in my case, you need to subtract two.
Hugo
Dear Hugo,
I did a test on our big cluster now. I see for some VMs WMI lists the IDs as 2:0, 2:1 and 2:2 but for others it lists the IDs as 1:0, 1:1 and 1:2. The strange thing is these VMs (w2k8R2) were installed with the same image. What could I do to get results from all VMs no matter if their IDs are 1 or 2? Thanks a lot for your help!
One possible in one scenario: if you are certain you never use more than one SCSI Controller in a vm. Then you can remove the checking of the SCSI Bus ID:
Hugo
I do not get results.
this is the only output i receive.

Is this because I tried to add the DiskFileSizeGB object you mentioned in the comments in the Script Repository post? Your script is what I’m looking for, however, without the DiskFileSizeGB object, it doesn’t give what I need.. Thanks in advance!
can someone please post the full script, i cant get it to work
Is there a way to exclude some servers? Because Linux servers will get an error.
Hi,
Looks like win32_diskdrive’s scsiport -1 or scsiport- 2 doesnt always work for all environments.
For example in my environment for scsi controllers 0, 1, 2, 3 bus numbers are 0, 1, 2, 3 respectively.
I have attached vmdks to these sci controllers but the windows assigned random port numbers.
it assigned 2, 5, 4, 3 for the disks that are attached 0, 1, 2, 3 scsi controllers.
So am i missing something? is there any other way to map a vmdk to a windows physical disk.
Regards,
Dreamer
this sript is excactly that what i need.
but when i tried it, i just get a “VM is powered off” but im sure our filesevers are powered on…
how comes that?
