HOW TO: Find HBA WWN number on VMware vSphere ESX server

There are several ways to get HBA WWNs on VMware vSphere ESX/ESXi host:

  1. vSphere Client;
  2. Using ESXi Shell;
  3. Using Powershell / PowerCLI script.

1. Connect to a server or vCenter, open server Configuration tab, under Hardware select Storage Adapters:

You can also copy WWNN (World Wide Node Name) and WWPN (World Wide Port Name)

2. How to find HBA WWN via ESXi Shell / CLI:

VMware vSphere ESXi 5.0+:

~ # esxcli storage core adapter list
HBA Name  Driver        Link State  UID                                   Description
--------  ------------  ----------  ------------------------------------  ------------------------------------------------------------
vmhba0    megaraid_sas  link-n/a    unknown.vmhba0                        (0:1:0.0) LSI / Symbios Logic MegaRAID SAS SKINNY Controller
vmhba1    fnic          link-up     fc.20000025b5020110:20000025b502a121  (0:8:0.0) Cisco Systems Inc Cisco VIC FCoE HBA Driver
vmhba2    fnic          link-up     fc.20000025b5020110:20000025b502a120  (0:9:0.0) Cisco Systems Inc Cisco VIC FCoE HBA Driver

VMware ESX/ESXi 2.1.0 – 4.1.x:

~ # esxcfg-scsidevs -a
vmhba0  megaraid_sas      link-n/a  unknown.vmhba0                          (0:1:0.0) LSI / Symbios Logic MegaRAID SAS SKINNY Controller
vmhba1  fnic              link-up   fc.20000025b5020110:20000025b502a121    (0:8:0.0) Cisco Systems Inc Cisco VIC FCoE HBA Driver
vmhba2  fnic              link-up   fc.20000025b5020110:20000025b502a120    (0:9:0.0) Cisco Systems Inc Cisco VIC FCoE HBA Driver

OR

  • Connect to ESXi shell either via putty/SSH or DCUI (Direct Console User Interface) / server console
  • Run ‘ls /proc/scsi/‘ and check the folder names:
    ~ # ls /proc/scsi/
     mptsas   qla2xxx
  • Look for a folder like ‘qla2xxx‘ – QLogic HBA, ‘lpfc820‘ – Emulex HBA, ‘bnx2i” – Brocade HBA;
  • Run ‘ls /proc/scsi/qla2xxx’. You will get a list of files, named by a number. Each file contains information about one HBA;
    ~ # ls /proc/scsi/qla2xxx/
    6  7
  • Now run ‘cat /proc/scsi/qla2xxx/6‘ to get full info on the HBA. Alternatively, run the following commands:
    • Run ” cat /proc/scsi/qla2xxx/6 | grep -A3 ‘SCSI Device Information:’  ” to get WWNN and WWPNs:
      ~ # cat /proc/scsi/qla2xxx/6 | grep -A3 'SCSI Device Information:'
      SCSI Device Information:
      scsi-qla0-adapter-node=20000024ff31f0c8:000000:0;
      scsi-qla0-adapter-port=21000024ff31f0c8:000000:0;
    • Run ” cat /proc/scsi/qla2xxx/6 | grep ‘Host Device Name’ ” to get vmhba number:
      ~ # cat /proc/scsi/qla2xxx/6 | grep 'Host Device Name'
      Host Device Name vmhba3

3. Powershell script to list host name, vmhba number, HBA model / driver and World Wide Port Name (WWN):
$scope = Get-VMHost     # All hosts connected in vCenter
#$scope = Get-Cluster -Name 'MyCluster' | Get-VMHost # All hosts in a specific cluster
foreach ($esx in $scope){
Write-Host "Host:", $esx
$hbas = Get-VMHostHba -VMHost $esx -Type FibreChannel
foreach ($hba in $hbas){
$wwpn = "{0:x}" -f $hba.PortWorldWideName
Write-Host `t $hba.Device, "|", $hba.model, "|", "World Wide Port Name:" $wwpn
}}

Result:

Host: ESXi5-001.vstrong.info
vmhba1 | Cisco VIC FCoE HBA Driver | World Wide Port Name: 20000025b502a101
vmhba2 | Cisco VIC FCoE HBA Driver | World Wide Port Name: 20000025b502a100

    What does {0:x} -f do? (I mean, I see that it formats the WWPN properly, but how does it do it?)

    Hi Abdel,

    I checked in our production environments is workign perfectly fine. I really appreciate you.

    Hi All,

    In our prod environment we are using EMC and Netapp storage in VMware environment. so we are planning to decommission EMC storage and using only Netapp.

    I need powercli scripts to get any VMs that are not on Netapp storage. so that we will plan to moving the VMs to new Netapp datastore.
