Serial Number Under "Disks" Incorrect

Good afternoon,

I have been seeing an issue, for a while now, with the serial numbers for eight HDDs that are connected via USB. In the web interface, they all show a serial number of 152D00539000, however, when I run the command smartctl -a /dev/sdX, I can see all of the drive details, include a serial number (WD-WCC7...).

The model number appears mostly correct and it shows a SMART status of "PASSED", so I am assuming that is working.

It makes tracking the drives very difficult in the GUI. Is there a way to correct this?

Thank you.
 
we get the (short) serial from the command
Code: 
udevadm info -p 'block/sdX' --query  all
we use the 'ID_SERIAL_SHORT' field from there

edit: small fix in command

Hi @dcsapak

Thank you very much, that is actually the one shown in pve.


Bash: 
root@pvenode1:~# udevadm info -p 'block/sdc' --query  all

My SAS drives also show an ID_SCSI_SERIAL, and it's the one shown in lshw -C disk:

Bash: 
 lshw -C disk
[....]
 *-disk:2
       description: SCSI Disk
       product: X423_TAL13900A10
       vendor: NETAPP
       physical id: 0.2.0
       bus info: scsi@0:0.2.0
       logical name: /dev/sdc
       version: NA01
       serial: X4O0A02RFUZ5
       size: 838GiB (900GB)
       capacity: 1042GiB (1119GB)
       capabilities: 10000rpm
       configuration: ansiversion=3 logicalsectorsize=512 sectorsize=512

For SATA ssd disks, the ID_SCSI does not exists and the serial from lshw and udevadm do match.

Now: which one should I use to pass in a passthrough scenario? I'm trying to follow this: https://pve.proxmox.com/wiki/Passthrough_Physical_Disk_to_Virtual_Machine_(VM) that points here (down to point 5 Bonus for passing Serial, they use the one from lshw OR the one from pve, but they are different in my sas scenario): https://dannyda.com/2020/08/26/how-to-passthrough-hdd-ssd-physical-disks-to-vm-on-proxmox-vepve/

I would need this to try making the disks available directly to a trueNAS vm (it needs the serial to properly manage zfs pools).

Thank you very much,
 
i am not sure what you're asking... if you want to passthrough the disk, just use a 'stable' link in /dev/disk/by-id/...
if there are more than one for your disk, you should be able to use any of them (as long as it's stable, it does not matter which you're using)
