.SH NAME
scsieject \- control SCSI tape devices
.SH SYNOPSIS
scsieject [-f <scsi-generic-device>] commands
.SH DESCRIPTION
The
.B scsieject
command controls SCSI devices in a platform-independent
manner. As long as 'mtx' works on the platform, so does 'scsieject'.
.SH OPTIONS
The first argument, given following
.B -f
, is the SCSI generic device corresponding to your tape drive.
Consult your operating system's documentation for more information (for
example, under Linux these are generally /dev/sg0 through /dev/sg15,
under FreeBSD these are /dev/pass0 through /dev/passX. Under Solaris
this is usually the same as your tape drive (Solaris has a SCSI passthrough
ioctl). You can set the STAPE or TAPE environment variable rather
than use -f.
.P
.SH COMMANDS
.TP 10
.B load
Load the medium into the drive. When this command is issued to a CD/DVD drive
and the tray is extended the tray will be retracted if the drive is capable of it.
.TP 10
.B unload
Unload the medium from the drive (also known as eject). When this command is issued
to a CD/DVD drive or a tape drive the media will be ejected if the device supports it.
.TP 10
.B start
Start the device. Some devices require a start command after a media changer has
loaded new media into the device.
.TP 10
.B stop
Stop the device. Some devices require a stop command prior to unloading the medium
from the device when using a media changer.
.TP 10
.B lock
Lock the device. Locks the device so that the medium cannot be removed manually.
.TP 10
.B unlock
Unlock the device. Unlocks the device so that the medium can be removed manually.
.SH AUTHORS
This program was written by Robert Nelson <robertnelson@users.sourceforge.net>
based on the scsitape program written by Eric Lee Green <eric@badtux.org>.
Major portions of the 'mtxl.c' library used herein were written by
Leonard Zubkoff.
.P
.SH HINTS
Under Linux,
.B cat /proc/scsi/scsi
will tell you what SCSI devices you have.
You can then refer to them as
.B /dev/sga,
.B /dev/sgb,
etc. by the order they
are reported.
.P
Under FreeBSD,
.B camcontrol devlist
will tell you what SCSI devices you
have, along with which
.B pass
device controls them.
.P
Under Solaris 7 and 8,
.B /usr/sbin/devfsadm -C
will clean up your /devices directory. Then
.B find /devices -name 'st@*' -print
will return a list of all tape drives. /dev on Solaris is apparently only
of historical interest.
.SH BUGS AND LIMITATIONS
There are no known bugs or limitations.
.SH AVAILABILITY
This version of
.B scsieject
is currently being maintained by Robert Nelson <robertnelson@users.sourceforge.net>
as part of the 'mtx' suite of programs. The 'mtx' home page is
http://mtx.sourceforge.net and the actual code is currently available there and via
SVN from http://sourceforge.net/projects/mtx.
