.SH NAME
smartd \- S.M.A.R.T. Daemon
.SH SYNOPSIS
.B smartd  
[\-pX\]

.SH DESCRIPTION
.B smartd
is a daemon that monitors 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
smartd is compatible with ATA/ATAPI-5 and earlier standards (see
REFERENCES below)

.B smartd  
is daemon designed to notify users of S.M.A.R.T. errors and changes of
S.M.A.R.T. attributes via the SYSLOG interface.  These notifications
and warnings normally appear in /var/log/messages.

.PP
.SH SYNTAX
.PP
.B 
smartd 
takes either no arguments, or a single argument.  The optional
argument begins with a '\-' followed by a letter or letters. Multiple
options must begin with a single '\-'.

The 
.B
smartd
daemon scans for all devices that support S.M.A.R.T., using
"/dev/hd*" for IDE/ATA devices, and "/dev/sd*" for SCSI devices.  It
polls these devices every 30 minutes checking for S.M.A.R.T. errors.
.PP
.SH 
OPTIONS
.TP
p
Prints license and copyright information onto STDOUT and into the SYSLOG
log (normally /var/log/messages) and then exits.
.TP
X
Runs smartd in "debug" mode. In this mode, it does not fork and
displays status information to STDOUT.


.SH EXAMPLES

.B
smartd
.fi
runs in forked (daemon) mode. This is the normal way to run
.B
smartd
.fi

    Note that smartmontools provides a start-up script in
.B
/etc/rc.d/init.d/smartd
which is responsible for starting and stopping the daemon via the normal init interface.  This can be enabled  using the command:
.nf
/sbin/chkconfig --add smartd
.fi
and disabled using the command:
.nf
/sbin/chkconfig --del smartd

If you would like to understand better how S.M.A.R.T. works, and what
it does, a good place to start is  Section 8.41 of the 'AT
Attachment with Packet Interface-5' (ATA/ATAPI-5) specification.  This
documents the S.M.A.R.T. functionality which the smartmontools
utilities provide access to.  You can find Revision 1 of this document
at:

Future versions of the specifications (ATA/ATAPI-6 and ATA/ATAPI-7),
and later revisions (2, 3) of the ATA/ATAPI-5 specification are
