All disks visible but external SSD enclosure not recognized

[SimpleWorld]

Hi, I have an external USB 3.2 Sabrent enclosure in which there are 4 4tb SSDs.

Only one drive is present when I access the WebGui in TrueNas Scale (Storage -> Disks). Same if I try to create a pool

If on the server, I issue the command

Code:

smartctl -a /dev/sda

What should I do to have TrueNas see all the drives?
