Best/Right way to extract disk serial number?

itnaa · 08-20-2007, 02:03 PM

What is the best & right way (command-line) to extract the serial numbers of my hard disks? I have a hardware mirrored RAID setup (using 3ware's 9550SX-8LP).

I checked out various things and the following seemed to work, for eg,

% sginfo -a /dev/sdc | grep Serial

and I do that for all my mounts.

Is this the right way? Is there a better way?

Since I'm mirroring, is there a way to probe the serial numbers of the disk pairs that are being mirrored?

Any help would be much appreciated!! Thanks.

lshw returns serial numbers (run it as root)

Thanks pixellany. Installed it and tried it out... rather extensive.

Is it possible to discover the serial numbers of each mirrored set? I noticed that it gave serial numbers of one of each set.

Thanks.

Not sure I understand--I think lshw gives info only the the actual hardware. Are you saying that it does not see all the hardware?

Thanks pixellany. I did not put it well...What I meant was that I have 8 similar disks arranged in mirror mode, so effectively 4 disks available. When I run lshw, it provides the serial numbers for 4 disks. I was wondering how to get the serial numbers of the remaining 4 disks. Perhaps it isn't possible when one uses hardware RAID? Maybe I need one of the 3ware cmd-line utilities?
