TAPEINFO(1)		    General Commands Manual		   TAPEINFO(1)

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  is-
       sues  raw commands directly to the tape drive, using either the operat-
       ing 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 operat-
       ing systems.

       One good	time to	use 'tapeinfo' is immediately after a tape i/o	opera-
       tion  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 sys-
       tem's  own  'mt'	or similar tape	driver control program.	It is intended
       to supplement, not replace, programs like 'mt' that access your operat-
       ing 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 <robertnel-
       son@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.
