Linux: Find out serial / model number and vendor information for SATA and IDE hard disk

How do I find out the make, model and serial number for my SCSI or IDE hard disks under CentOS Linux server? How do I get vendor information about my disk storage w/o opening my Intel / AMD server chassis?



You need to use the hdparm command. It provides a command line interface to various hard disk ioctls supported by the stock Linux ATA/IDE/SATA device driver subsystem i.e. get BIOS information from hard disk.

ADVERTISEMENTS



Getting hard disk model and number under Linux

Try command as follows for /dev/sda (SATA). You need to pass -i or -I option which request identification info directly from the drive, which is displayed in a new expanded format:

# hdparm -I /dev/sda

# hdparm -I /dev/sda | grep Serial

OR for IDE /dev/hda

# hdparm -i /dev/hda

OR

# hdparm -I /dev/hda

Sample outputs:

/dev/sda: ATA device, with non-removable media Model Number: SAMSUNG SV2002H Serial Number: 0395J1FR904324 Firmware Revision: RA100-04 Standards: Used: ATA/ATAPI-6 T13 1410D revision 1 Supported: 6 5 4 Configuration: Logical max current cylinders 16383 16383 heads 16 16 sectors/track 63 63 -- CHS current addressable sectors: 16514064 LBA user addressable sectors: 39180960 device size with M = 1024*1024: 19131 MBytes device size with M = 1000*1000: 20060 MBytes (20 GB) Capabilities: LBA, IORDY(cannot be disabled) Standby timer values: spec'd by Standard, no device specific minimum R/W multiple sector transfer: Max = 16 Current = 16 Recommended acoustic management value: 128, current value: 0 DMA: mdma0 mdma1 mdma2 udma0 udma1 *udma2 udma3 udma4 udma5 Cycle time: min=120ns recommended=120ns PIO: pio0 pio1 pio2 pio3 pio4 Cycle time: no flow control=120ns IORDY flow control=120ns Commands/features: Enabled Supported: SMART feature set Security Mode feature set * Power Management feature set * Write cache * Look-ahead * Host Protected Area feature set * WRITE_BUFFER command * READ_BUFFER command * NOP cmd * DOWNLOAD_MICROCODE SET_MAX security extension Automatic Acoustic Management feature set * Mandatory FLUSH_CACHE Security: Master password revision code = 65534 supported not enabled not locked not frozen not expired: security count supported: enhanced erase 20min for SECURITY ERASE UNIT. 20min for ENHANCED SECURITY ERASE UNIT.

scsi_id command examples

For SCSI attached disk use scsi_id command which queries a SCSI device via the SCSI INQUIRY vital product data (VPD) page 0x80 or 0x83 and uses the resulting data to generate a value that is unique across all SCSI devices that properly support page 0x80 or page 0x83.

# scsi_id -s /block/sda

# scsi_id -a -s /block/sda

# scsi_id -gus /block/sda

Where,

-s : Generate an id for the sysfs-device

: Generate an id for the sysfs-device -a : Always print information (model, vendor strings) about the device even if it does not support VPD pages.

: Always print information (model, vendor strings) about the device even if it does not support VPD pages. -g : Treat the device as white listed. The -g option must be specified on the command line or in the scsi_id configuration file for scsi_id to gener ate any output

: Treat the device as white listed. The -g option must be specified on the command line or in the scsi_id configuration file for scsi_id to gener ate any output -u : Reformat the output : replace all whitespaces by underscores.

sdparm command

The sdparm command can be used to access SCSI modes pages; read VPD pages; send simple SCSI commands. It can provide all information:

# sdparm -a /dev/sda

# sdparm --vendor sea /dev/sda
