Tech Tip: Retrieve Disk Info from the Command Line
You can use the following command line tools to retrieve the make and model of your hard drives without the need to open up your system.
First, you need the device names of your disks, for this you can use df or cat /proc/partitions. Example device names are names such as /dev/hda or /dev/sdb. For the following examples, where applicable, I will use /dev/sda as my disk device.
Use the lshw command:
$ lshw -class disk ... -disk:0 product: ST3250310NS vendor: Seagate version: SN04 serial: 9SF0000TH size: 232GiB (250GB)
Use the smartctl command:
$ smartctl -i /dev/sda ... Device Model: ST3250310NS Serial Number: 9SF0000TH Firmware Version: SN04 ...
Note: You may need to install the 'smartmontools' package, your output will vary depending on smartctl version and disk make/model.
Use the hdparm command:
$ hdparm -i /dev/sda /dev/sda: Model=ST3250310NS, FwRev=SN04, SerialNo=9SF0000TH ...
Use the hwinfo command:
$ hwinfo --disk ... Model: "ST3250310NS" Device: "ST3250310NS" Revision: "SN04" Serial ID: "9SF0000TH" ...
Note: You may need to install the 'hwinfo' package.
Note, you will need to be root to get the full output from these commands.
And one additional way that you can determine the model and serial number of your disk:
$ ls /dev/disk/by-id ata-ST3250310NS_9SF0000TH ata-ST3250310NS_9SF0000TH-part1 ata-ST3250310NS_9SF0000TH-part2 ata-ST3250310NS_9SF0000TH-part3
Here the model number is ST3250310NS, and the serial number is 9SF0000TH.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
