USB drive as Datastore in vSphere 6

Hi,

Can I create a Datastore on a USB drive?

I am trying to follow this guide but it doesnt work.

I have done the steps bellow but the disk doesnt show up.

1. Connect to the ESXi host with SSH
3. Stop the USB arbitrator service. This service is used to passthrough USB device from an ESX/ESXi host to a virtual machine. (When disabling it, you can no longer passthrough USB devices to VMs)

   ~ # /etc/init.d/usbarbitrator stop

5. (optional) Use this command to permanently disable the USB arbitrator service after reboot.

   ~ # chkconfig usbarbitrator off

7. Plug in the USB Device to your ESXi host
9. Get the device identifier (mpx.vmhbaXX). You should see the USB Device in /dev/disks/:

   ~ # ls /dev/disks/
