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. +.P +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. +.P +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. +.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 start at /dev/sg0 +under FreeBSD these start at /dev/pass0). +.P +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. + +.SH BUGS AND LIMITATIONS +.P +This program has only been tested on Linux with a limited number of +tape drives (HP DDS4, Seagate AIT). +.P +.SH AVAILABILITY +.B 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://sourceforge.net/projects/mtx. + +.SH SEE ALSO +.BR mt (1), mtx (1), scsitape (1), scsieject (1), loaderinfo (1) |
