loaderinfo

LOADERINFO(1)						      General Commands Manual						     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 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://source-
       forge.net/projects/mtx.
