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).
