Linux: Find out serial / model number and vendor information for SATA and IDE hard disk
Q. 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?
A.. You need to use hdparm command. It provides a command line interface to various hard disk ioctls supported by the stock Linux ATA/IDE/SATA device driver subsystem.
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
OR for IDE /dev/hda
# hdparm -i /dev/hda
Sample oiutput:
/dev/sda:

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
- -a : 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
- -u : Reformat the output : replace all whitespaces by underscores.

Thanks! - In CentOS, the command for SCSI info is, appropriately enough,
scsi-info
