       tapeinfo - report SCSI tape device info


       tapeinfo -f <scsi-generic-device>


       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

       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


       The first argument, given following -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

       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.


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