NAME

6       tapeinfo - report SCSI tape device info
7

SYNOPSIS

9       tapeinfo -f <scsi-generic-device>
10

DESCRIPTION

12       The  tapeinfo  command  reads various information from SCSI tape drives
13       that is not generally available via  most  vendors'  tape  drivers.  It
14       issues  raw commands directly to the tape drive, using either the oper‐
15       ating system's SCSI generic device ( e.g. /dev/sg0 on Linux, /dev/pass0
16       on  FreeBSD) or the raw SCSI I/O ioctl on a tape device on some operat‐
17       ing systems.
18
19       One good time to use 'tapeinfo' is immediately after a tape i/o  opera‐
20       tion  has  failed.  On  tape  drives that support HP's 'tapealert' API,
21       'tapeinfo' will report a more exact description of what went wrong.
22
23       Do be aware that 'tapeinfo' is not a substitute for your operating sys‐
24       tem's  own  'mt' or similar tape driver control program. It is intended
25       to supplement, not replace, programs like 'mt' that access your operat‐
26       ing system's tape driver in order to report or set information.
27

OPTIONS

29       The  first  argument,  given  following -f , is the SCSI generic device
30       corresponding to your tape drive.  Consult your operating system's doc‐
31       umentation  for  more  information  (for example, under Linux these are
32       generally start at /dev/sg0 under FreeBSD these start at /dev/pass0).
33
34       Under FreeBSD, 'camcontrol devlist' will tell you what SCSI devices you
35       have,  along  with which 'pass' device controls them. Under Linux, "cat
36       /proc/scsi/scsi" will tell you what SCSI devices you have.

BUGS AND LIMITATIONS

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