Jak zjistit číslo modelu linuxové diskové jednotky?

Zkuste hdparm program:

# hdparm -i /dev/sdc
/dev/sda:

 Model=INTEL SSDSA2CW080G3, FwRev=4PC10362, SerialNo=CVPR112003RA080BGN
...

-i možnost hdparm lze použít k získání identifikačních informací.

Nejsem si jistý, jestli je to ve všech distribucích, ale zkuste se podívat do /dev/disk/by-id:

$ ls -l /dev/disk/by-id/
razem 0

Můžete také zkusit grepping dmesg pro název zařízení:

# dmesg|grep -C3 sda

V tomto případě je to ST31000528AS.

zkuste spustit:

$ sudo lshw

Všimněte si, že zmiňuje vaše ID blokovaného zařízení jako logical name a také sériové číslo jako product . Toto můžete použít k fyzickému rozlišení vašich disků
