.SH NAME
smartctl \- S.M.A.R.T. control and monitor utility 
.SH SYNOPSIS
.B smartctl [options] device

.SH DESCRIPTION
.B smartctl
controls the Self-Monitoring, Analysis and Reporting Technology
(S.M.A.R.T.) system built into many ATA-3 and later ATA, IDE and
SCSI-3 hard drives. The purpose of S.M.A.R.T. is to monitor the
reliability of the hard drive and predict drive failures, and to carry
out different types of drive self-tests.  This version of smartctl is
compatible with ATA/ATAPI-5 and earlier standards (see REFERENCES
below)

.B smartctl
is a command line utility designed to perform S.M.A.R.T. tasks such as
printing the S.M.A.R.T. self-test and error logs, and enabling and
disabling S.M.A.R.T. automatic testing. Note: if the user issues a
S.M.A.R.T. command that is (apparently) not implemented by the device,
we print a warning message but issue the command anyway.  This should
not cause problems: unimplemented S.M.A.R.T. commands issued to a
drive are ignored and return an error.

.B smartctl
also provides limited TapeAlerts support for some SCSI tape drives and
changers.

The user must specify the device to be controlled or interrogated as an
argument to
.B smartctl.
ATA devices use the form "/dev/hd*" and SCSI devices use the form "/dev/sd*".
For SCSI Tape Drives and Changers with TapeAlerts support use the devices
"/dev/st*" and "/dev/sg*".  More general paths may also be specified.
.B smartctl
will attempt to guess the device type, but the '\-d' option can be used to
specify a device type of ATA or SCSI if required.


.PP
.SH OPTIONS
.PP
The options are grouped below into several categories.
.B smartctl
will execute these in the order: INFORMATION, ENABLE/DISABLE, DISPLAY
DATA, RUN/ABORT TESTS.

SCSI devices only accept the options 
.B \-h, \-?, \-V, \-i, \-a, \-d, \-s, \-H, \-t, \-C
and 
.B \-X.
