LUN report – datastore, RDM and node visibility

When you are running multi-node vSphere clusters, you probably already had the experience that one or more of your LUNs were not visible on all nodes. Now you can try to find out which LUN is missing on which node the hard way through the vSphere client. Or you can use the force of PowerCLI and run a script that will report all this in a handy spreadsheet.

To make the script as flexible as possible it should be able to handle any n-node cluster. And as you some of you might know, the Export-CSV cmdlet has some problems with variable length rows. Luckily there is a handy solution I already used in my yadr – A vDisk reporter post.

The script

Annotations

Line 1: The definition of the parameters that can be used with the script. Note that the second parameter takes a default when is not present.

Line 3: If you would run the script multiple times from the same PowerCLI prompt you would get an error saying “Add-Type : Cannot add type. The type name ‘LunInfo’ already exists.“. To avoid this error the script generates on each run a random number between 1 and 99999, which it appends to the type name. This should, unless you have thousands of clusters avoid the error message.

Line 5-19: Since the number of nodes is unknown before the script is actually running, I create a new type, called LunInfon (where n is the random number generated before).

Line 14-16: The new type will contain a property for each node in the cluster. The name of this property is the first qualifier of the FQDN of the host.

Line 21: The script keeps all the information it will gather in a hash table called $scsiTab. The key into the hash table is composed from short hostname and the Canonical name of the LUN.

Line 26-33: From the information provided by the Get-ScsiLun cmdlet, the script will populate the hash table. In this loop the CanonicalName and the Capacity of the LUN are stored in the hash table.

Line 36-43: From the Datastore object the script finds out for all datastores in the cluster which LUN they use.

Line 45-55: The script runs through all the virtual machines on the cluster and checks all virtual disks if they are RDM backed. If the script encounters a RDM it stores the name of the virtual machine and the label of the hard disk in the hash table.

Line 57-68: All the information in the hash table is now grouped per Canonical name. For each Canonical name the script creates a LunInfon object and stores the information from the hash table in that object.

Line 69-70: The array with LunInfon objects is exported to a CSV file and the CSV file is opened.

Usage

You save the script as a .ps1 file. In the example screenshots below I used the name Cluster-LUN-list.ps1.

Start the PowerCLI prompt and make sure that you are connected to the vCenter.

From the PowerCLI prompt you can call the script with the name of a cluster as a parameter.

In this case the script will create the CSV file as C:\Temp\MyCluster17-LUN.csv.

Or you pass the name of the CSV file as a second parameter to the script.

In this case the script will store the report in LunRpt.csv on the root of the D-partition.

Note that some local disks seem to have the same Canonical name on all nodes in a cluster. I experienced that with some IBM RAID Controllers. In that case the entries for those disks will not be correct in the report. In itself this is not really a problem since those disks are local and no LUNs from the SAN.

The report

The following screenshot shows a report made for a 4-node cluster.

You can clearly see which LUNs are:

only visible on 1 of the nodes
used as RDM disks
used for datastores
still available

This report will surely make it easier to talk with your Storage Administrator 😉

I like the script and I want to use it but is not working because hosts name contains dots.

Our hosts are named with dot inside, basically IP of the host is also set as name, and script failes for this reason.

I tried to change the script but I can’t make it run, maybe you can give a hint.

I tried like this:

param($clusName,$csvName=(“C:\Temp\” + $clusName + “-LUN.csv”))
$rndNum = Get-Random -Maximum 99999
$LunInfoDef = @”
public string ClusterName;
public string CanonicalName;
public string UsedBy;
public string SizeMB;
“@
$LunInfoDef = “public struct LunInfo” + $rndNum + “{n" + $LunInfoDef $esxServers = Get-Cluster $clusName | Get-VMHost | Sort-Object -Property Name $esxServers | %{ #$LunInfoDef += ("ntpublic string " + ($_.Name.Split(".")[0]) + ";") #$LunInfoDef += ("ntpublic string " + ($_.Name) + ";") #$LunInfoDef += ("ntpublic string " + [Regex]::Escape(($_.Name)) + ";") #$LunInfoDef += ("ntpublic string " + """($_.Name)) + "";") $LunInfoDef += ("ntpublic string " + "“” + ($_) + “";") } $LunInfoDef += "n}”
Add-Type -Language CsharpVersion3 -TypeDefinition $LunInfoDef

#$key = $esxImpl.Name.Split(“.”)[0] + “-” + $_.CanonicalName.Split(“.”)[1]
$key = $esxImpl.Name + “-” + $_.CanonicalName.Split(“.”)[1]
if(!$scsiTab.ContainsKey($key)){
$scsiTab[$key] = $_.CanonicalName,””,$_.CapacityMB
}
}

$key = $esxImpl.Name + “-” + $_.DiskName.Split(“.”)[1]
$scsiTab[$key] = $scsiTab[$key][0], $dsName, $scsiTab[$key][2]
}

}

but I get this errors:

Hello Lucd!

I tested the script in the powershell version, and it worked:

NameValue
—- —–
PSVersion 5.1.14409.1027
PSEdition Desktop

but in versions other than 5.1 and variations or version 7 of powershell, I can’t generate the information.

NameValue
—- —–
PSVersion 7.3.3
PSEdition Core
GitCommitId 7.3.3
OS Microsoft Windows 10.0.19044

Some of the errors I get:

Line |
15 | Add-Type -Language CsharpVersion3 -TypeDefinition $LunInfoDef
| ~~~~~~~~~~~~~~
| Cannot bind parameter ‘Language’. Cannot convert value “CsharpVersion3” to type “Microsoft.PowerShell.Commands.Language”. Error: “Unable to match the identifier name CsharpVersion3

My question is this: Are there requirements to use your script? I installed framework 3.5 and still, I can’t successfully run your script in the mentioned versions of powershell.

Thank you Lucd!

Hi LucD,

How to fetch the details for all the clusters in a vcenter into one file.

Thanks,

You remove the Export-Csv and Invoke-Item in the script.

Then create a foreach loop, and in there call the updated script for each cluster.
Get-Cluster | Foreach-Object -Process { .\Cluster-LUN-list-updated.ps1 $_.Name } | Export-Csv -Path .\report.csv -NoTypeInformation -UseCulture

Hi LucD
Nice Script thank you very much

I would like to add the Lun Number for each NAA.* found in the report with this command
$esxcli.storage.core.path.list($_.DeviceName) | %{new-object PSObject -Property @{LunId =”L”+$_.Lun}}
if you have an idea

LucD, I’m trying to run your script against a VCSA 5.5 envrionment, using PowerCLI 5.5 R1 from a Win2012 box…I am very much a novice with regards PowerCLI, but can normally modify someone else’s code to meet my needs…that said, I’m having issues running this script in my environment…it is a mixed environment of hosts named with IP and others with hostname (something that was implemented prior to me coming here) and that may be part of my problem…below are the errors I see when running the command against a cluster named “Development”…

Hi LucD,

I have a cluster with 10 ESXi hosts and about 50 RDM LUN’s. Do you have a script that I can run to detach all these RDM’s on all the hosts in the cluster. The VMware method of detaching RDM’s from vSphere client is fine, but for a couple of RDM’s only.

Thanks in advance

Joe

June 1, 2015 at 22:00

Just to clarify, you mean detach the RDMs from the VMs, in that cluster, to which they are attached ?
Or do you mean something else ?

Script works great and generates the report Im looking for, minus the VMName which is blank. I do get an error (see below) but it doesnt seem to be talking about the VMName. Is there a reason why the VMName isnt populating in the excel spreadsheet?

Here’s the error Im getting, but the CanonicalName is populating.

Get-ScsiLun : Cannot validate argument on parameter ‘CanonicalName’. The argument is null or empty. Provide an

LucD, first, wanted to say thanks, I learn so very much from your posts and scripts. Second, I work in a shop with a large VM environmet, including clusters with in excess of 20 hosts and hundreds of LUNs presented to each. We had a need to determine the LUN # of disks on a host by host basis. So I did some HallMark scripting, when you care to copy the very best. When I added a get-ScsiLun to the loops, it took over 12 hours to process a single host in a large cluster. to resolve this, Using your code as the base, and adding a second hash table to store scsi LUN RTN values in, while that takes 10 minutes or so to build, the largest clusters now process in 20 minutes or so. also added logic to process a single cluster or all clusters and messaging. Thought some of your followers might find it helpful.

I ran this against one of my test Clusters that have hit the limit of LUN’s per host (Mostly Oracle RDM’s).

Under each host in a cluster it gives me different letters? h, v, a, m, and b. Not sure what they mean? The ClusterName, CanonicalName, and UsedBy give me data that makes sense, its just the data under the hosts.

Hi Ryan,
Which PowerShell version are you running ?
Do a $psversiontable.

It could also be something went wrong in the copy/paste of the code.
Double click inside the code window, that should select all code, and then you can do a copy, followed by a paste into your editor.

@LucD ~ Excellent script! Thank you so much for posting this! I have found this VERY useful! I have two feature request – if possible? When you get a chance, can you edit your script and add the following?

– Add the VM that is using the RDM in the UsedBy column, so the cell is not left empty
– Find NFS mount points and add them to the list too?

Once again, thank you for posting your script!

David

Hi Luc

Any chance you have a version of this script that can query the entire Virtual Centre. Need to find a way to list all SCSI devices from a specific array to assist with a cleanup or de-comm process.

Thanks

Johan

LucD

January 20, 2014 at 19:27

Hi Johan, do you have several clusters in your vCenter ? If yes, you could call the script for each cluster. Something like
Get-Cluster | %{./Cluster-LUN-List.ps1 $_.Name}
This would produce a CSV file per cluster.

If you also have stand-alone ESXi servers in your vCenter, the script would need some changes.
Btw, do you have shared datastores between the stand-alone ESXi servers ?

Hi Lucd,

This is excellent script, been handy for all FC datastore inconsistent mappings..
But, we have lot many “NFS datastores” on large number of Clusters..

Can you provide separate script, which can check whether “NFS datastores” are uniformly mapped to all ESX Hosts in cluster or not?? If any misses highlight same (like your above script)??

Thank you in adv..

This looks like a great script. But I am unable to run it because I have hyphens in the ESX host names.

Is there a workaround to that issue? Your help would be appreciated.

Joe

November 30, 2012 at 10:13

Seems I’ve run into a problem. Been using the script for some time now with no issues. Then suddenly starte getting errors. What seems to be occurring is we now have a few Esx hosts that do not have names, rather their .name is an up address like 10.10.10.10. The current split using a “.” ends up with duplicate since each key/ public struct will be 10. I attempted doing a replace of the “.” with nothing so the name would end up 10101010 but that gives an invalid token.

Any thoughts? Also note the same cluster has both named hosts and hosts with ip addresses only. The only way I have gotten it to semi work was to first replace all “.” with ‘ ‘ and then add a letter both infront an behind the result. So it would look like a10101010a and aESXSRV1a.

Any idea’s?

Thanks
Joe

What if the disk is presented to two ESXs, one ESX (lets call it esx1) is in this cluster, and one not (lets call it esx2). In that case we will get that RDM is available, even if some vm on esx2 is using tha RDM disk?

Hi LucD.
I’m using a script to create a .csv file to monitor the latency of my datastores.
In this report I put the information I need in this way:

Entity = $oEntry.Entity

EntityId = $oEntry.EntityId

Instance = $oEntry.Instance

MetricId = $oEntry.MetricId

Timestamp = ($oentry.Timestamp).toString(‘dd/MM/yyyy HH:mm’)

Value = $oEntry.Value

Unit = $oEntry.Unit

}

Now, I would like to know if there is a way to change the , that return something like that: 4d4b3f85-db8f3f4c-3fc4-984be1xxxxxx,
with the name of the datastore.
Thank you

Hi Sal,
It looks as if the Add-Type in line 19 didn’t work.
Do you get any message before the ones you include in your comment ?
Are you running the script from a PowerCLI prompt ?
Luc

LucD

May 15, 2012 at 13:39

@Sal, it looks like you might have copied the line numbers as well.
In the script box, at the top right, there will be some icons that appear when you hover over them.
Click the 2nd icon from the left (“copy to clipboard”).
In an editor you can now do Ctrl-V to paste the script.

Sumanth :Hi,
This script doesnt work against ESX5 environment. Any changes are required ?

LucD

May 9, 2012 at 17:48

@Sumanth, it should work against ESX5.
Are you using PowerPath ?
Or do you have hyphens in the names of your ESX5 servers or datastores ?
Any error messages ?

I am receiving the errors that have been noted. My VM’s and ESXi Hosts have “-” in the names. Not my idea.

I have tried to add the line
$LunInfoDef += (“ntpublic string ” + ($_.Name.Split(“.”)[0].Replace(‘-‘,”)) + “;”)

And attempted to modify all lines with “-“.

Example:
Hostname: okc-clu-esx01
VM: okc-clu-vm01

Hi Brian, I replied in the thread you created on the VMTN PowerCLI Community.
In short, my earlier reply to Phil, shows how to replace the hyphen in 5 lines with another character to solve the problem.
I hope that helps.

after replacing the luninfo code this what i get

@Devanshu, that line should be
$LunInfoDef += (“ntpublic string ” + ($_.Name.Split(“.”)[0].Replace('-','')) + ";")

But see my answer to Phil, there is no need to eliminate the hyphen in the host names, just pick another character.

Phil

April 6, 2012 at 16:35

@Phil
should it be:
$LunInfoDef += (“ntpublic string ” + ($_.Name.Split(“.”)[0] -Replace(‘-‘,”)) + “;”)

LucD

April 6, 2012 at 19:09

Hi Phil, the hyphen I used to join the hostname and the canonicalname in the hash tab key, is probably not the best choice 🙁 Since the hyphen is an accepted value in a ESX(i) server name.
The easiest solution would be to replace the hyphen by another character (that is not used in your ESX(i) host names.
Replace the “-” in lines 28, 39, 51, 57 and 61 by any other character that doesn’t appear in your host names.

Phil

April 6, 2012 at 16:12

Wonderful script. I am having one problem though

I also have some servers with hyphens in their names. When I try:
$LunInfoDef += (“ntpublic string ” + ($_.Name.Split(“.”)[0]Replace(‘-‘,”)) + “;”)

it doesn’t like Replace. PowerGUI shows “unexpected ‘Replace’ in expression or statement”

March 9, 2012 at 20:29

@Alan, I think I know what happened.
The script dynamically defines a struct in C#. One of the members of that struct is given the name of the ESX(i) servers in the cluster.
It seems you have hyphens (-) in the names of your ESX(i) servers, and unfortunately C# doesn’t accept that character in a struct declaration it seems.
If you replace line 15
$LunInfoDef += ("ntpublic string " + ($_.Name.Split(".")[0]) + ";")

by this
$LunInfoDef += ("ntpublic string " + ($_.Name.Split(".")[0]Replace('-','')) + ";")

it might work.
The disadvantage is that the names of your ESX(i) will be missing the hyphens in their names

the one with csv output works fine. Thanks!

December 30, 2011 at 08:37

Thanks for the great script LucD.

Is there a way we can get a HTML report for all the clusters in the VC and then add this report to a mail, something like a daily check. This will help to keep a track of the paths and generate some kind of availability report or so.

Thanks again!

LucD

December 30, 2011 at 13:52

@Amit, that is not that difficult with PowerShell.
The adapted script will get a LUN report for all the clusters.
Make sure to update the parameters in the Send-MailMessage cmdlet !
You can download the script here.

@Andreas, that could be related to the .Net version you have installed on the PC where you run the script. What .Net version(s) do you have installed ?
For PowerCLI you have to have “NET 2.0, 3.0, or 3.5 with Service Pack 1” (as per the Release Notes)

@LucD
Hi Luc,

Yes and no. I’ve had a look at the SDK reference and see what you mean, but if the Device Type is listed just as Virtual Disk, how can I then get a listing of the Properties for a particular disk including the sub properties in the Backing information?

As far as I can tell, you need to poll the backing info in order to establish the kind of Virtual Disk it is (RDM, PM, VM or regular Disk), or am I making my life more difficult than it needs to be?

Again, as far as I can tell, I need to be able to list all the properties available to me in order to find a property that matches in both the backing or device info and the properties from either get-scsilun or Config.StorageDevice.Scsilun in order to be able to list the VM, the RDM filename and location, and the LUN number that the RDM is pointing at.

LucD

June 17, 2011 at 01:08

You can use the typename of the object that sits behind the ‘backing’ property to take the correct branch in your code.
For example:
switch($dev.backing.GetType().Name){ 'VirtualDiskFlatVer2BackingInfo' { # A regular VHD } 'VirtualDiskRawDiskVer2BackingInfo'{ # A RDM } }
Does that make it any clearer ?

Alasdair Carnie

June 16, 2011 at 18:29

Hi Luc,

I’ve been playing around with the script you wrote on extracting RDM info per VM and I’ve run into a problem. I cannot seem to get a list of all properties for a specific device.

I ran the script below, but I need to see what other properties are available under the main backing property, and also list the LUN number as part of the report.

$report = @()
$vms = Get-VM | Get-View
foreach($vm in $vms){
foreach($dev in $vm.Config.Hardware.Device){
if(($dev.gettype()).Name -eq “VirtualDisk”){
if(($dev.Backing.CompatibilityMode -eq “physicalMode”) -or
($dev.Backing.CompatibilityMode -eq “virtualMode”)){
$row = “” | select VMName, VMHost, HDDeviceName, HDFileName, HDMode, HDsize, HDDisplayName
$row.VMName = $vm.Name
$esx = Get-View $vm.Runtime.Host
$row.VMHost = ($esx).Name
$row.HDDeviceName = $dev.Backing.DeviceName
$row.HDFileName = $dev.Backing.FileName
$row.HDMode = $dev.Backing.CompatibilityMode
$row.HDSize = $dev.CapacityInKB
$row.HDDisplayName = ($esx.Config.StorageDevice.ScsiLun | where {$_.Uuid -eq $dev.Backing.LunUuid}).DisplayName
$report += $row
}
}
}
}

I have tried different permutations of get-member, but get nothing returned. Is there a simple way to get a listing of all properties for backing?

LucD

June 16, 2011 at 19:00

The backing property comes in many flavors, depending on the type of device.
All these are documented in the SDK Reference.
For example, for a regular virtual disk you can look at the VirtualDiskFlatVer2BackingInfo object.
From the base backing object, see VirtualDeviceBackingInfo, you can find all the types in the Extended by section.
Does that help you ?

Stew

June 8, 2011 at 03:51

Do you have a script that will return the storage path count for each ESX host/vmhba? great script by the way.

LucD

June 8, 2011 at 08:11

@Stew, thanks.
Do you mean something like this ?
Get-VMHost | Get-ScsiLun -LunType Disk | ` Select @{N="Host";E={$_.VMHost.Name}}, @{N="HBA";E={$_.RuntimeName.Split(':')[0]}}, @{N="LUN";E={$_.CanonicalName}}, @{N="#Paths";E={(Get-ScsiLunPath -ScsiLun $_).Count}} | ft -AutoSize

Rod Repp

February 23, 2011 at 21:48

One suggestion, break out not only the LUNs per host, but the luns per host HBA. Trying to find how many hosts amongst hundreds don’t have redundant links to their storage . . . .

LucD

February 23, 2011 at 22:46

@Rodd, that’s a good suggestion. I’ll have a look.

Hi Todd, I have the impression your copy of the script went wrong somewhere. Hover your mouse of the script window and you should see in the top-right corner of the window 4 icons. Use the 2nd icon from the left, it will copy the script to your clipboard.
And yes, the script should also work against a cluster of ESXi hosts.

Hi lucD,

The script failed to run at $esxImpl | get-scsiLun | where {$_.Luntype -eq “Disk”} ….

the error message:
Get-ScsiLun : Value cannot be null.

I tried to run this command with the script… just “get-vmhost | get-scsilun”
and it failed again with the same error message…

any idea way?

Thanks!

James

August 13, 2010 at 21:19

Can you run this against all the clusters in vCenter or do you have to specify a specific cluster?

LucD

August 13, 2010 at 22:10

Hi James, the script, as it is, only runs against a specific cluster specified in the first parameter.
But it’s quite easy to run against all your clusters. Something like this for example

Get-Cluster | %{.\Cluster-Lun-List.ps1 $_.Name}

This will produce a separate CSV file for each cluster.

Pcli

June 24, 2010 at 14:59

Can we use Export-Xls rather than usage of | Export-Csv $csvName -NoTypeInformation -UseCulture

LucD

June 25, 2010 at 02:58

Sure you can.
Make sure the function Export-Xls is available, define a new param (for example $xlsName instead of $csvName) and then make the last line something like this:
| Export-Xls -Path $xlsName -WorksheetName "LUN report" -AppendWorksheet:$false
You can have a worksheet for each of your clusters in one spreadsheet. Great idea.

LucD

April 19, 2010 at 11:46

Ossie,
Line 22 is the start of a loop over all ESX servers that are in the cluster.
Line 23 stores the loop variable ($_) in another variable, called $esxImpl.

Unfortunately I don’t have a cluster of ESXi hosts handy for testing right now.
Can you check if
Get-VMHost "one-of-the-ESXi-hosts" | Get-ScsiLun
returns anything ?

Ossie

April 19, 2010 at 10:34

Hi Luc

Thanks for the reply. I did think that might be the issue so as you suggested had tried just the Get-Cluster “cluster name with spaces” | Get-VMHost and it returns the single host in this cluster, with power status and other stats.
Obviously others have the script working OK so I’m not sure what could be wrong here. BTW -What is the purpose of lines 22 and 23?
Thanks again

Hi Ossie,
It looks as if there is no ESX server found for the clustername you passed to the script. Could you check if this returns one or more ESX servers ?
Get-Cluster "clustername" | Get-VMHost
Where “clustername” is the first parameter you passed in the script call. That would be MyCluster17 in the Usage section sample calls.
Luc.

Why are you putting *screenshots* of a *console session* ? Wouldn’t copying the text be easier (go through a graphics program, crop the image, save then import the image in your blogging software VS copying two lines from the console)? Not to mention consume less bandwidth?

Other than those details, looks neat.

works great.. when the cluster names don’t have spaces in the names! 😉

(okay I didn’t get it to work 100% but the yadr works perfect – just no cluster names. I ran it against the entire vcenter. Sorted the CSV file for RDM=True and viewed the path name to infer the LUN connection/Host / cluster relationship.

Very handy! Thanks! lots to (more) to learn!
