Multible USB HD's are not show in storrage/drive

TrueNAS General

Hi,
I’ve a USB-3 storrage for 4 HD’s and my first function check at my Ubuntu 22 PC with a Raid 6 was successful.
The Storrage is a Xysteck PX-2590-657.
My Labhost is a Dell OptiPlex 7720 with 32GB RAM
I’ve installed TrueNAS-12.0-U8.1 on it.
When I plug in the storrage, I can see all 4 HD’s in /dev

root@truenas[~]# ls -lah /dev | grep " da[0-9]"
crw-r-----   1 root  operator   0xa5 Aug 17 11:45 da0
crw-r-----   1 root  operator   0xa6 Aug 17 11:45 da1
crw-r-----   1 root  operator   0xa7 Aug 17 11:45 da2
crw-r-----   1 root  operator   0xa8 Aug 17 11:46 da3

But in storrages / Disk I can see only da3.

Because my trueNAS version is a bit old, I’ve updated it to the last stable Version (13) first core then scale, but the same problem at all versions.

When I pluged in two single USB HD’s and I can see both HD’s in /dev bothe HD’s listed at the WebUI.

Because I can see the HD’s from the Storrage in /dev I guess it’s not a Hardware or a driver problem. Have someone a idear?

If I had to guess you’re impacted by:

USB attached SATA disks may use the same serial number, confusing software that attempts to detect multipathed disks.

Edit:
// If sata ports are unavailable or limited on the machine I’d strongly recommend getting a cheap LSI HBA with firmware flashed to IT mode for ~$30 USB on ebay instead of continuing to try getting USB HDDs working. You’ll save yourself a lot of time & lost data.

I also can’t find that specific model of OptiPlex, but I’m hoping you got at least 1 free Pcie slot available somewhere in there. Don’t forget to slap a fan in pointing at the HBA.
