LOADERINFO(1)                                                    LOADERINFO(1)




NAME

       loaderinfo - report SCSI tape device info


SYNOPSIS

       loaderinfo -f <scsi-generic-device>


DESCRIPTION

       The  loaderinfo  command reads various information from SCSI tape load-
       ers. 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).
