How to get NAA for lun or volume

[HASMIK_HAYRAPETYAN]

Hi,

I am looking for ways to get NAA identifier for NetApp volumes and luns using DFM Server API. Does DFM's API provide such functionality?

Thanks in advance for any help.

Ok, folks, same story, but for c-mode?

There is no Get-NcLunSerialNumbercommand.

Just to remind you, simple script for 7-mode

$LUNs = Get-NaLun
foreach ($LUN in $LUNs)
{
    $sn = Get-NaLunSerialNumber $LUN.Path
    $b = $sn.ToCharArray();
    Foreach ($element in $b) {$c = $c + [System.String]::Format("{0:X}", [System.Convert]::ToUInt32($element))}
    $LUNWWN = "naa.60a98000" + $c
    Write-Host $sn $LUNWWN $LUN.Path
    
}

Hi,

Sure it's possible to convert the LUN Serial number to its Naa number for clustered data ONTAP using PowerShell. Here is a simple example

Import-Module DataONTAP

$cluster      = "cluster1.netapp.com"
$vserver      = "vserver1"
$lunPath      = "/vol/vol1/luns/lun1"
$identifier   = "naa.600a0980"
$credentials  = $host.ui.PromptForCredential("Connect to cluster $cluster", "Please enter the user name and password","","")
$cluster      = Connect-NcController $cluster -Credential($cred)
$lun          = Get-NcLun -Vserver $vserver -Path $lunPath -Controller $cluster
$serialNumber = $lun.SerialNumber
$ca           = $serialNumber.ToCharArray();
$naasn        = $null
Foreach($byte in $ca){
   $naasn = $naasn + [System.String]::Format("{0:x}", [System.Convert]::ToUInt32($byte))
}
Write-Host "LunPath,LunSerial,NaaNumber"
Write-Host "$lunPath,$serialNumber,$identifier$naasn"

The output will look like:

LunPath,LunSerial,NaaNumber
/vol/vol1/luns/lun1,BpEwv$ElzqhW,naa.600a0980427045777624456c7a716857

Also note that you can use the "lun serial -x" command in ONTAP 8.3 if you'd prefer to use the CLI. See following KB
