Identification of HDD by SATA port number

Solution 1:

lsscsi --verbose will provide output similar to this:

[0:0:0:0]    disk    ATA      TOSHIBA THNSNH12 HTRA  /dev/sda 
  dir: /sys/bus/scsi/devices/0:0:0:0  [/sys/devices/pci0000:00/0000:00:1f.2/ata1/host0/target0:0:0/0:0:0:0]
[1:0:0:0]    disk    ATA      WDC WD2003FZEX-0 01.0  /dev/sdb 
  dir: /sys/bus/scsi/devices/1:0:0:0  [/sys/devices/pci0000:00/0000:00:1f.2/ata2/host1/target1:0:0/1:0:0:0]
[2:0:0:0]    disk    ATA      WDC WD3001FAEX-0 01.0  /dev/sdc 
  dir: /sys/bus/scsi/devices/2:0:0:0  [/sys/devices/pci0000:00/0000:00:1f.2/ata3/host2/target2:0:0/2:0:0:0]
[3:0:0:0]    cd/dvd  Optiarc  DVD RW AD-7280S  1.01  /dev/sr0 
  dir: /sys/bus/scsi/devices/3:0:0:0  [/sys/devices/pci0000:00/0000:00:1f.2/ata4/host3/target3:0:0/3:0:0:0]

which provides the ataN port which can matchup with information found in the syslog. Useful if you are trying to determine where an error is coming from .

Edit: If which lsscsi provides no output you need to install it:

sudo apt-get install lsscsi

Further Edit:

This probably goes without saying, but of course you can filter the output with grep to locate what you are interested in for instance if you find an error like ata4: status: { DRDY ERR } you could simple issue the command

lsscsi --verbose | grep -P1 -A1 ata4 Which would produce output like this:

[3:0:0:0]    cd/dvd  Optiarc  DVD RW AD-7280S  1.01  /dev/sr0 
  dir: /sys/bus/scsi/devices/3:0:0:0  [/sys/devices/pci0000:00/0000:00:1f.2/ata4/host3/target3:0:0/3:0:0:0]

Which would indicate that the device (Optiarc DVD RW AD-7280S on ata4) wasn't ready when called upon.

This should be enough information to allow you to locate the troubled device.

Solution 2:

sudo lshw -c storage -c disk gives you a lot of info regarding your hard-drives. Eg:

 *-scsi:1
      physical id: 2
      logical name: scsi2
      capabilities: emulated
    *-disk
         description: ATA Disk
         product: ST31000524AS
         vendor: Seagate
         physical id: 0.0.0
         bus info: scsi@2:0.0.0
         logical name: /dev/sdb
         version: JC4B
         serial: 5VPDESM5
         size: 931GiB (1TB)
         capabilities: gpt-1.00 partitioned partitioned:gpt
         configuration: ansiversion=5 guid=d6e747d2-3e9c-47c2-865b-44f8d7cc5808 sectorsize=512
       *-volume
            description: EXT4 volume
            vendor: Linux
            physical id: 1
            bus info: scsi@2:0.0.0,1
            logical name: /dev/sdb1
            logical name: /mnt/hdd0
            version: 1.0
            serial: 2de34713-f0ee-4a12-9214-21a5431a7b7b
            size: 931GiB
            capabilities: journaled extended_attributes large_files huge_files dir_nlink recover extents ext4 ext2 initialized
            configuration: created=2013-07-20 14:14:09 filesystem=ext4 lastmountpoint=/mnt/hdd0 modified=2013-08-29 21:29:24 mount.fstype=ext4 mount.options=rw,relatime,errors=remount-ro,data=ordered mounted=2013-08-29 21:29:24 state=mounted

I suspect physical id gives you the physical port the HDD is connected to (2 in this case).

Solution 3:

sudo apt-get install lsscsi

tech@tech:~$ lsscsi
[2:0:0:0]    disk    ATA      SAMSUNG HD040GJ/ ZG10  /dev/sda
[3:0:1:0]    disk    ATA      WDC WD3200AAJS-0 03.0  /dev/sdb
[4:0:0:0]    disk    Generic- Compact Flash    1.00  /dev/sdc
[4:0:0:1]    disk    Generic- SM/xD-Picture    1.00  /dev/sdd
[4:0:0:2]    disk    Generic- SD/MMC           1.00  /dev/sde
[4:0:0:3]    disk    Generic- MS/MS-Pro/HG     1.00  /dev/sdf

this utility will give you ATA port 0 to 3.
