Find HBA WWN number on VMware vSphere ESX server

afox123

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

• 　　vSphere Client;
  
• 　　Using ESXi Shell;
  
• 　　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:

• 　　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:
  　　?
  

  1 2	~ # 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;
  　　?
  

  1 2	~ # 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:
    　　?
    

    1 2	~ # 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):
　　?

1 2 3 4 5 6 7 8 9

$scope = Get-VMHost     # All hosts connected in vCenter #$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:
　　?
