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.
