VcHostFibreChannelHba.device doesn't reflect what is seen in vCenter

I'm writing some workflows to take care of automatic zoning using the Cisco MDS REST API.  As part of that I need to be able to identify ESXi host HBAs on the SAN fabric.  Today, we create device aliases based on the name of the HBA in vCenter.  For example, if I have a host called tstdev-hb2-0004 and it shows HBAs vmhba0, vmhba1, vmhba2, vmhba3, my aliases would be:

tstdev-hb2-0004-vmhba0

tstdev-hb2-0004-vmhba1

tstdev-hb2-0004-vmhba2

tstdev-hb2-0004-vmhba3

When I run this code:

for each (var hba in u_host.configManager.storageSystem.storageDeviceInfo.hostBusAdapter)

{ 

  if (hba instanceof VcHostFibreChannelHba)

  {

  System.log(hba.device);

  }

}

I expect:

vmhba0

vmhba1

vmhba2

vmhba3

(which is what is displayed in vCenter)

But what I get back is:

vmhba1

vmhba2

vmhba3

vmhba4

How can I get the display names as displayed in vCenter?

Interestingly, this code:

for each (var hba in u_host.configManager.storageSystem.storageDeviceInfo.hostBusAdapter)
{  
  System.log('Device Name: ' + hba.device);
  System.log('Device Type: ' + hba.driver);
  if (hba instanceof VcHostFibreChannelHba)
  {
  System.log('FC HBA: ' + hba.device);
  }
}

Produces this:

[2017-05-02 14:58:17.973] [I] Device Name: vmhba0

[2017-05-02 14:58:17.975] [I] Device Type: megaraid_sas

[2017-05-02 14:58:17.990] [I] Device Type: usb-storage

In vCenter, I don't see an HBA of type megaraid sas.

What the following command return, if you run it directly from ESXi server console?

     esxcfg-scsidevs -a
