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/sdaWith 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/sdaThe 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/sddscsi_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/scsiTo 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 Rigid Disk Geometry mode page (x) ----------------------------------- Number of cylinders 65535 Number of heads 255 Starting cyl. write precomp 65535 Starting cyl. reduced current 65535 Device step rate 0 Landing Zone Cylinder 0 RPL 0 Rotational Offset 0 Rotational Rate 15000
To obtail all disk info use sginfo -a
# sginfo -a /dev/sdd | more
