HDD device naming

  • Hi togehter,


    can anybody explain me who the naming is done for the hdd/ssds?

    I got some wd drives and some toshiba drives.


    My os ssd (WD) is connected to Sata port 1 and if there is only the wd is connected it is getting /dev/sda

    But if there is a toshiba connected the WD ist getting /dev/sdb and the toshiba sda.


    I was thinking that this naming is done by the Sata port numbering and not according the device manufacturer.


    Cheers Robert

  • No, the kernel names the devices based on a ruleset. And because of this behaviour predictable device names HAVE to be used for filesystems (which is done by OMV), because you can never be sure that /dev/sda1 will not become /dev/sdb1 when another disk is detected.
