[CentOS] Controlling the order of /dev/sdX devices?

[Cal Sawyer]

Nope sir.  Assume never the same device twice and no control over those
devices, so UUID is out of the question.

 

thank you,

You could assign a LABEL to each hard drive. The LABEL is attached to
the
drive's UID (I think?) so even if you move the drive to anther port it
will
still be accessible via the same LABEL

Yes, that's why you assign a LABEL to the device :) If the same hard
drive gets used on the same server, but on random ports every time then
the LABEL will still stay the same. I have a similar setup where I mount
about 40-odd USB drives to a server on a regular basis. They each have
their own mount points in /mnt/usb-hdd/xxxxxxxxxx and irrespective of
which drive I connect to which USB port, or on which order, they all get
mounted where they're supposed to :)
