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).
