Unix & Linux Stack Exchange is a question and answer site for users of Linux, FreeBSD and other Un*x-like operating systems.. It's 100% free, no registration required.

Seeing the device name by df, is it somehow possible to resolve it to the physical drive name such as vendor / type.

/dev/sda3               915.4G     34.9G    880.0G   4% /share/HDA_DATA
/dev/sdd3                 1.8T    668.1G      1.1T  36% /share/HDD_DATA

I have learnt that I find some info in sys/block, but I do not find the vendor's type name in there?

My system is a Linux based QNAP NAS, so things might be a little different there. For me as a non Linux expert hard to tell, what is "standard", and what not.

-- Added as of Steven's answer --

[~] # hdparm -I /dev/sdb3

/dev/sdb3:
 HDIO_DRIVE_CMD(identify) failed: Invalid argument

Maybe you have more luck with dmesg or dmesg | grep -C10 sda. –  jippie Jun 2 '12 at 18:26
    
Or sudo smartctl --all /dev/sda (requires root privileges). –  jippie Jun 2 '12 at 18:27
    
The dmesg approach works, thx. Will rate your answer below as correct, and add a comment. –  Horst Walter Jun 2 '12 at 22:08
    
Similar messages will appear in /var/log/syslog or /var/log/dmesg. Exact file name is highly dependent on distribution. –  jippie Jun 2 '12 at 22:16

On my QNAP NAS I do not find this lshw command. Checked /sbin /usr/sbin Any idea where else I could find it? I believe you this is working, unfortunately not on my Linux based NAS. –  Horst Walter Jun 2 '12 at 17:54
    
I am using the dmesg approach, as in jippie's comment above. Will rate this as answer anyway, since it is correct. –  Horst Walter Jun 2 '12 at 22:10

Most modern Linux systems use udev to manage devices. This isn't the case on all embedded devices though; I don't know whether this specific device uses udev.

udevadm info -n /dev/sda3 -a
udevadm info -n /dev/sda3 -q property

will print everything the system knows about /dev/sda3. This is the same info you'll find in /sys, but udev does the work of walking down the hierarchy to collect all the data.

Again no luck with my QNAP system, udevadm not available. Nevertheless we do have a comprehensive summary of commands here right now, thanks. –  Horst Walter Jun 4 '12 at 8:05

The QNAP NAS products run firmware that is essentially a custom Linux distro. It is quite spartan, with a minimal set of command line tools (and many of those provided by busybox). Fortunately, there is a decent implementation of hdparm in there, so you should be able to query a drive, as follows:

hdparm -I /dev/sda

Here's the output I get from a "QNAP TS-239 Pro NAS" with a "Western Digital RE4 1TB" drive (output is verbatim, except for the drive's serial number, which I have purposely obscured):

Checksum: correct

"Vendor" and "Type" are not explicitly reported by hdparm. However, "Model Number" is reported, and a quick web search on it should yield anything you need to know about a drive.

Sounds good, in my case I do get the following response: HDIO_DRIVE_CMD(identify) failed: Invalid argument Have updated question. –  Horst Walter Jun 2 '12 at 23:31
    
@Horst: Try hdparm -I /dev/sdb instead. /dev/sdb3 is most likely not a drive, but a partition, and hdparm needs a drive. –  Steven Monday Jun 3 '12 at 2:06
    
Thanks for the hint, but no luck. I have tried sda, sdb, sdb3, sda3 etc, all the same issue HDIO_DRIVE_CMD(identify) failed: Invalid argument Run it as admin, which should be root on QNAP, sudo I cannot find (tried sudo hdparm ...) –  Horst Walter Jun 3 '12 at 8:50

Install gsmartcontrol a GUI tool with loads of information: http://gsmartcontrol.berlios.de/home/images/info_identity.png

Useful hint, but the system is a QNAP NAS, I cannot install GUI related tools. Thanks anyway, and sorry that I did not tell this in the question. –  Horst Walter Jun 2 '12 at 17:33
