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 writ­
                 ing 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 con­
       trols  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.

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