Smartctl command to find disk info

smartctl is a linux tool which is used to perform disk analysis

 # smartctl -a -d cciss,0 /dev/cciss/c0d0

The smartctl program also allows for you to view and test SMART attributes of a drive. You can quickly check the overall health of a drive by using

 # smartctl -H /dev/sda

   SMART overall-health self-assessment test result: PASSED

For Obtaining drive information -i option will be useful

 # smartctl -i /dev/sda

With the above command you can find information like disk serial number and lots of disk information

Performing short and long disk test

 # smartctl --test=short /dev/sda
 # smartctl --test=long /dev/sda
 # smartctl -a /dev/sda

The above will first perform a short test of the /dev/sda device. This usually takes about a minute to perform, and the smartctl output will tell you when you can check the results. Next, the long test: this one can take quite a bit longer (about two hours here on a 320GB SATA drive). Finally, use the -a option to view the results

scsi_id command to querys a SCSI device via the SCSI INQUIRY

 # /sbin/scsi_id -g -p 0x80 -s /block/sdd

scsi_id command to querys 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

How do I find out hard disk model and serial number

 # cat /proc/scsi/scsi

To find diskinfo you can also use sginfo

sg3_utils is a collection of linux utilities for devices that use the SCSI command set for installing sginfo command install sg3_utils package as below

Install scsiinfo or sg3_utils package

 # yum install sg3_utils

 # sginfo -g /dev/sdb

# sginfo -g /dev/sdb
