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 per-
       form simple S.M.A.R.T. tasks.



OPTIONS
       smartctl  accepts  two  agruments,  options  and device in
       respective order. The options begin with a '-' and  multi-
       ple  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  Fail-
              ures

       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. thresh-
              olds

       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 min-
              utes)

       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)
