NAME

       tapeinfo - report SCSI tape device info

SYNOPSIS

       tapeinfo -f <scsi-generic-device>

DESCRIPTION

       The  tapeinfo  command  reads  various information from SCSI tape drives that is not generally available via most vendors' tape drivers. It
       issues raw commands directly to the tape drive, using either the  operating  system's  SCSI  generic  device  (	e.g.  /dev/sg0	on  Linux,
       /dev/pass0 on FreeBSD) or the raw SCSI I/O ioctl on a tape device on some operating systems.

       One  good  time	to  use 'tapeinfo' is immediately after a tape i/o operation has failed. On tape drives that support HP's 'tapealert' API,
       'tapeinfo' will report a more exact description of what went wrong.

       Do be aware that 'tapeinfo' is not a substitute for your operating system's own 'mt' or similar tape driver control program. It is intended
       to supplement, not replace, programs like 'mt' that access your operating system's tape driver in order to report or set information.

OPTIONS

       The first argument, given following -f , is the SCSI generic device corresponding to your tape drive.  Consult your operating system's doc-
       umentation for more information (for example, under Linux these are generally start at /dev/sg0 under FreeBSD these start at /dev/pass0).

       Under FreeBSD, 'camcontrol devlist' will tell you what SCSI devices you have, along with which 'pass' device controls  them.  Under  Linux,
       "cat /proc/scsi/scsi" will tell you what SCSI devices you have.

BUGS AND LIMITATIONS

       This program has only been tested on Linux with a limited number of tape drives (HP DDS4, Seagate AIT).

AVAILABILITY

       tapeinfo  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://source-
       forge.net/projects/mtx.

NAME

       scsieject - control SCSI tape devices

SYNOPSIS

       scsieject [-f <scsi-generic-device>] commands

DESCRIPTION

       The scsieject command controls SCSI devices in a platform-independent manner. As long as 'mtx' works on the platform, so does 'scsieject'.

OPTIONS

       The first argument, given following -f , is the SCSI generic device corresponding to your tape drive.  Consult your operating system's doc-
       umentation 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.

COMMANDS

       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.

       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.

       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 manually.

       unlock	 Unlock the device.  Unlocks the device so that the medium can be removed manually.

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.

HINTS

       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.

BUGS AND LIMITATIONS

       There are no known bugs or limitations.
