NAME

       smartctl - S.M.A.R.T. control utility

SYNOPSIS

       smartctl [-cdeglostv] [device]

DESCRIPTION

       smartctl  controls the Self-Monitoring, Analysis and Reporting Technology System(S.M.A.R.T.) built into ATA-3 and later IDE and SCSI-3 Hard
       Drives. This is used to check the reliability of the hard drive and predict drive failures. TapeAlerts support for  SCSI  tape  drives  and
       changers smartctl is command line utility designed to perform simple S.M.A.R.T. tasks.

OPTIONS

       smartctl  accepts  two agruments, options and device in respective order. The options begin with a '-' and multiple options should be begun
       with a single '-'. The second argument is the device to be controled. ATA device use the form "/dev/hd*" and  SCSI  devices  use  the  form
       "/dev/sd*".  SCSI devices use only options a,i,c,e,d. For SCSI Tape Drives and Changers with TapeAlerts support use the form "/dev/st*" and
       "/dev/sg*". TapeAlerts devices use only a,i,c,e,d.

       i      Check if the device supports S.M.A.R.T

       c      Check if device has any S.M.A.R.T. Warranty  Failures

       g      Prints only the generic S.M.A.R.T. attributes

       v      Prints only the vendor specific S.M.A.R.T. attributes

       t      Prints only the vendor specific S.M.A.R.T. thresholds

       l      Prints only the S.M.A.R.T. error log

       a      Prints all parameters for c,i,g,v,t,l (for SCSI c,i)

       e      Enables S.M.A.R.T. on device

       d      Disables S.M.A.R.T. on device

       t      Enables S.M.A.R.T. automatic offline self test timer which scans the drive every four hours for disk defects.

       T      Disables S.M.A.R.T. automatic offline self test timer

       O      Runs S.M.A.R.T. Immediate off-line Test

       S      Runs S.M.A.R.T. Short Self Test ( usually under ten minutes)

       s      Runs S.M.A.R.T. Short Self Test in Captive Mode.
	       ( WARNING: This test will busy out drive for length of test. Only run this on drives without any mounted partitions.)

       X      Runs S.M.A.R.T. Extended Self Test ( tens of minutes)

       x      Runs S.M.A.R.T. Extended Self Test in Captive Mode.  ( WARNING: This test will busy out drive for length of test. Only run  this	on
	      drives without any mounted partitions.)

       A      Aborts Non-Captive S.M.A.R.T. Tests.

EXAMPLES

       smartctl -a /dev/hda - prints all S.M.A.R.T. infomration for drive /dev/hda (Primary Master)

       smartctl -d /dev/hdd - disable S.M.A.R.T. on drive /dev/hdd (Secondary Slave)

NAME

       hd - MFM/IDE hard disk devices

DESCRIPTION

       The  hd*  devices  are block devices to access MFM/IDE hard disk drives in raw mode.  The master drive on the primary IDE controller (major
       device number 3) is hda; the slave drive is hdb.  The master drive of the second controller (major device number 22) is hdc and	the  slave
       hdd.

       General	IDE block device names have the form hdX, or hdXP, where X is a letter denoting the physical drive, and P is a number denoting the
       partition on that physical drive.  The first form, hdX, is used to address the whole drive.  Partition numbers are assigned  in	the  order
       the  partitions	are  discovered,  and only nonempty, nonextended partitions get a number.  However, partition numbers 1-4 are given to the
       four partitions described in the MBR (the "primary" partitions), regardless of whether they are unused or extended.  Thus, the first  logi-
       cal  partition  will be hdX5.  Both DOS-type partitioning and BSD-disklabel partitioning are supported.	You can have at most 63 partitions
       on an IDE disk.

       For example, /dev/hda refers to all of the first IDE drive in the system; and /dev/hdb3 refers to the third DOS "primary" partition on  the
       second one.

       They are typically created by:

	      mknod -m 660 /dev/hda b 3 0
	      mknod -m 660 /dev/hda1 b 3 1
	      mknod -m 660 /dev/hda2 b 3 2
	      ...
	      mknod -m 660 /dev/hda8 b 3 8
	      mknod -m 660 /dev/hdb b 3 64
	      mknod -m 660 /dev/hdb1 b 3 65
	      mknod -m 660 /dev/hdb2 b 3 66
	      ...
	      mknod -m 660 /dev/hdb8 b 3 72
	      chown root:disk /dev/hd*
