User mezzantrop provides us with a simple script on how to find the name of your drives on FreeBSD. Check out the link below for more information on the GEOM script.
This is one of the trickiest question for a new (and sometimes for an experienced) FreeBSD user, and even Handbook advises to see the “dmesg” output to check the drives:
“Inspect `/var/run/dmesg.boot` to ensure the new disk was found. In this example, the newly added SATA drive will appear as `ada1`.”
Actually, there are many methods and utilities to check drives, and one of the most powerful tool is “camcontrol”. But what if you are dealing with GEOM stack or checking a partition?
