Get LUN info from ESX host

[qwert1235]

Hello:

Is there a way to extract LUNs info from ESX host?  I need LUN(s) number/ID in order to match it with ID storage admin is seeing...

Thanks a lot!

You can use the Get-ScsiLun cmdlet to extract LUN info from ESX hosts.

I think Get-SCSI LUN is very close, but I still do not see the LUN ID.

I run

Get-VMHost -Name "hostname" | Get-ScsiLun

and got the result:

Id                   : HostSystem-host-65635/vmhba1:1:1

CanonicalName        : vmhba1:1:1

RuntimeName          :

Key                  : key-vim.host.ScsiDisk-vmhba1:1:1

LunType              : disk

HostId               : HostSystem-host-65635

VMHostId             : HostSystem-host-65635

VMHost               : ID = HostSystem-host-65635

Uid                  : /VIServer=email@hostname:443/VMHost=HostSystem-host-65635/ScsiLun=vmhba1:1:

                       1/

ExtensionData        : VMware.Vim.HostScsiDisk

But here is still no info regarding LUN ID that I can see (match) on storage side.

How can I get just LUN ID info for all datastores on my hosts?

Thanks!

Best bet in cases like this is to google for s.th. like get-scsilun canonicalname lucd

Mabye this helps:

What exactly do you mean with LUN ID ?

Do you see the value in the vSphere client ? Is it one of these ?

Lol :smileylaugh:

[qwert1235]

the issue is that this VC 2.5 with ESX 3.5...

refering to your picture, I am looking for Identifier (last 3 characters, like 09c, 279, 199, on your picture) and have to match it with Datastores names.

I run your script and for canonical name I have something like vmhba1:1:16, but not naa.60060160d2c82200f2addfa66c2cdf11 like I hoped to see.

Is it possible to get this info from 3.5 hosts?

Thanks a lot!

We can try, back to the old-fashioned way of doing this.

Try this

foreach($esx in Get-VMHost){
    foreach($hbaKey in ($esx.Extensiondata.Config.StorageDevice.ScsiTopology.Adapter | where {$_.Adapter -like "*FibreChannelHba*"})){
        if($hbaKey.Target){
            foreach($tgtKey in $hbaKey.Target){
                foreach($lunKey in $tgtKey.Lun){
                    $hba = $esx.Extensiondata.Config.StorageDevice.HostBusAdapter | where {$_.Key -eq $hbaKey.Adapter}
                    $lun = $esx.Extensiondata.Config.StorageDevice.ScsiLun | where {$_.Key -eq $lunKey.ScsiLun}
                    Select-Object -InputObject $lun -Property @{N="Host";E={$esx.Name}},
                        @{N="HBA";E={$hba.Device}},
                        CanonicalName,DisplayName,@{N="LUN";E={$lunKey.Lun}}
                }
            }
        }
    }
}

Does it return the information you're after ?

Wow this is cool LucD

thanks for sharing it here with us.

how to export it to CSV, where should I put the Export-CSV comamnd in ?

[LucD · Accepted solution]

Sure, simplest way is like this

$report = foreach($esx in Get-VMHost){
    foreach($hbaKey in ($esx.Extensiondata.Config.StorageDevice.ScsiTopology.Adapter | where {$_.Adapter -like "*FibreChannelHba*"})){
        if($hbaKey.Target){
            foreach($tgtKey in $hbaKey.Target){
                foreach($lunKey in $tgtKey.Lun){
                    $hba = $esx.Extensiondata.Config.StorageDevice.HostBusAdapter | where {$_.Key -eq $hbaKey.Adapter}
                    $lun = $esx.Extensiondata.Config.StorageDevice.ScsiLun | where {$_.Key -eq $lunKey.ScsiLun}
                    Select-Object -InputObject $lun -Property @{N="Host";E={$esx.Name}},
                        @{N="HBA";E={$hba.Device}},
                        CanonicalName,DisplayName,@{N="LUN";E={$lunKey.Lun}}
                }
            }
        }
    }
} 
$report | Export-Csv "C:\lun-report.csv" -NoTypeInformation -UseCulture

Cool, many thanks for the reply Luc.

With your presence here the Powershell is now well known in IT wirld.
