scsieject - control SCSI tape devices
scsieject [-f <scsi-generic-device>] commands
The scsieject command controls SCSI devices in a platform-independent manner. As long as
'mtx' works on the platform, so does 'scsieject'.
The first argument, given following -f , is the SCSI generic device corresponding to your
tape drive. Consult your operating system's documentation for more information (for exam-
ple, 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.
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
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
start Start the device. Some devices require a start command after a media changer
has loaded new media into the device.
stop Stop the device. Some devices require a stop command prior to unloading the
medium from the device when using a media changer.
lock Lock the device. Locks the device so that the medium cannot be removed manu-

the scsitape program written by Eric Lee Green <email@example.com>. Major portions of the
'mtxl.c' library used herein were written by Leonard Zubkoff.
Under Linux, cat /proc/scsi/scsi will tell you what SCSI devices you have. You can then
refer to them as /dev/sga, /dev/sgb, etc. by the order they are reported.
Under FreeBSD, camcontrol devlist will tell you what SCSI devices you have, along with
which pass device controls them.
Under Solaris 7 and 8, /usr/sbin/devfsadm -C will clean up your /devices directory. Then
find /devices -name 'st@*' -print will return a list of all tape drives. /dev on Solaris
is apparently only of historical interest.
