--- name: "loaderinfo" section: "1" platform: "linux" package: "mtx" version: "1.3.12-18" release: "Debian 13 (Trixie)" platforms: ["linux"] url: "https://new.carta.tech/loaderinfo" --- # loaderinfo(1) report SCSI tape device info ## NAME loaderinfo - report SCSI tape device info ## SYNOPSIS loaderinfo -f \ ## 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 presence 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, the command **lsscsi --generic** 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, IBM TS3100). ## AVAILABILITY **loaderinfo** is currently being maintained by Robert Nelson \ 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. ## SEE ALSO [**mt**(1)](/mt/1.md),[**tapeinfo**(1)](/tapeinfo/1.md),[**mtx**(1)](/mtx/1.md)
