Identifying Physical Disks

[TAC]

What is the best way to label and keep track of physical disk drives in a FreeNAS server. Specifically when things go wrong, what physical disk(s) need to be dealt with?

I currently have my drives labeled with the FreeNAS drive name (da0, da1, etc.) and serial numbers, but am finding this still causes some confusion.
As shown below, the drive being replaced doesn't show a name, just the gptid (no name and no serial number). The 'glabel status' command doesn't show either of these gptids.

Also it appears the drive name (da0, da1, etc.) isn't permanently tied to the physical drive serial number so my drive labeling scheme needs some work.

And from Storage / Disk GUI it doesn't list the drives that are offline.

I've used gpart list to help identify drives. If you label your chassis with the serial numbers of the drives and then label the drives with the /dev/gptid/<hash> it may help connect the dots.

@PhiloEpisteme thanks for the input. So it looks like the drive s/n is tied to the gptid and you better not count on the drive name (dax).

In looking at the first drive from the gparts list it appear ada0p1 is some type of partition used by FreeNAS while ada0p2 is the usable storage name/section. Also the efimedia in ada0p2 is the pgtid reported in glabel status
