loaderinfo - report SCSI tape device info
loaderinfo -f <scsi-generic-device>
command reads various information from SCSI tape loaders. Its intendeduse is for high-level programs that are trying to decide what thecapabilities of a device are. The following are printed:
- Element Address Assignment Page:
- This tells how many elements are in the loader, and what their rawhardware addresses are.
- Transport Geometry Descriptor Page:
- Will display whether media is invertible or not (usable with someoptical jukeboxes for detirmining whether to "flip" media after writingto 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 havea bar code reader (for loaders that support the Exabyte extension forreporting presense of said reader).
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 (forexample, 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 youhave, along with which 'pass' device controls them. Under Linux,"cat /proc/scsi/scsi" will tell you what SCSI devices you have. UnderSolaris 8, find /devices -name '*changer*'
will display the device names for your attached changers. Make sureto configure your 'sgen' driver first.
BUGS AND LIMITATIONS
This program has only been tested on Linux with a limited number ofloaders (Ecrix Autopack, Exabyte 220).
is currently being maintained by Robert Nelson <robertnelsonAATTusers.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://sourceforge.net/projects/mtx.
