NAME

       loaderinfo - report SCSI tape device info

SYNOPSIS

       loaderinfo -f <scsi-generic-device>

DESCRIPTION

       The  loaderinfo command reads various information from SCSI tape loaders. Its intended use
       is for high-level programs that are trying to decide what the  capabilities  of  a  device
       are.

       The following are printed:

       Element Address Assignment Page:
                 This  tells  how  many  elements  are in the loader, and what their raw hardware
                 addresses are.

       Transport Geometry Descriptor Page:
                 Will display whether media is  invertible  or  not  (usable  with  some  optical
                 jukeboxes  for  detirmining  whether  to "flip" media after writing to the first
                 side).

       Device Capabilities Page
                 Currently will only display whether we can transfer between slots (i.e.  whether
                 'mtx transfer' works).

       Inquiry Page
                 Aside  from  the  normal inquiry info, will also print out whether we have a bar
                 code reader (for loaders  that  support  the  Exabyte  extension  for  reporting
                 presense of said reader).

OPTIONS

       The  first argument, given following -f , is the SCSI generic device corresponding to your
       tape loader.  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).

       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. Under Solaris 8, find /devices -name '*changer*' will  display  the
       device names for your attached changers. Make sure to configure your 'sgen' driver first.

BUGS AND LIMITATIONS

       This  program  has  only  been  tested  on  Linux  with a limited number of loaders (Ecrix
       Autopack, Exabyte 220).

AVAILABILITY

       loaderinfo     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.
