NAME

       loaderinfo - report SCSI tape device info

SYNOPSIS

       loaderinfo -f <scsi-generic-device>

DESCRIPTION

       The  loaderinfo	command  reads	various information from SCSI tape loaders. Its intended use is for high-level programs that are trying to
       decide what the capabilities of a device are.

       The following are printed:

       Element Address Assignment Page:
		 This tells how many elements are in the loader, and what their raw hardware addresses are.

       Transport Geometry Descriptor Page:
		 Will display whether media is invertible or not (usable with some optical jukeboxes for detirmining whether to "flip" media after
		 writing to the first side).

       Device Capabilities Page
		 Currently will only display whether we can transfer between slots (i.e.  whether 'mtx transfer' works).

       Inquiry Page
		 Aside	from  the normal inquiry info, will also print out whether we have a bar code reader (for loaders that support the Exabyte
		 extension for reporting presense of said reader).

OPTIONS

       The first argument, given following -f , is the SCSI generic device corresponding to your tape loader.	Consult  your  operating  system's
       documentation  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. Under Solaris 8, find /devices -name '*changer*' will display the device
       names for your attached changers. Make sure to configure your 'sgen' driver first.

BUGS AND LIMITATIONS

       This program has only been tested on Linux with a limited number of loaders (Ecrix Autopack, Exabyte 220).

AVAILABILITY

       loaderinfo 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.
