I am trying to attach two identical USB harddisks to ESXi 6.7 and followed the following guide to get the first disk working:
https://www.virten.net/2015/10/usb-devices-as-vmfs-datastore-in-vsphere-esxi-6-0/
This worked fine, but as soon as I plug in the second disk i noticed that no addition disk appears in /dev/disks.
If i unplug the first disk and plug in the second it appears under the same name in /dev/disks.
"esxcli storage core adapter list" shows the following...
HBA Name Driver Link State UID Capabilities Description
-------- -------- ---------- ----------- ------------ ----------------------------------------------------------------
vmhba0 vmw_ahci link-n/a sata.vmhba0 (0000:00:17.0) Intel Corporation Sunrise Point-H AHCI Controller
vmhba32 vmkusb link-n/a usb.vmhba32 () USB
vmhba33 vmkusb link-n/a usb.vmhba33 () USB
the disk also appears in lsub.

My guess is that due to the same device/vendor id, the disks are not appearing separately.
Is there anyone here who has an idea how i could solve this? Thanks!
