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:

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:

  ?

  1 2	~ # ls /proc/scsi/ mptsas qla2xxx

• Look for a folder like ‘qla2xxx‘ �C QLogic HBA, ‘lpfc820‘ �C Emulex HBA, ‘bnx2i” �C 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:

    ?

    1 2 3 4

    ~ # 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:
