Just as a point of reference we are using this code to control a
couple of big StorageTek tape libraries (9710 and 9730).  It has
worked flawlessly.  It also supports reading the VOLID barcodes.

I would second the notion that it should go into the mainline sources
if the author is interested.  Very useful utility in big IT shops
doing serious backup.

/dev/sch0 interface

[Jeff V. Merkey]

Is anyone actuaslly using the /dev/sch0 interface for SCSI tape changers
in Linux?  I noticed that the device definitions are present, but I do not 
see any driver shipped in the standard base that actually uses it.

Thanks

Jeff

I think pretty much everyone uses mtx via the sg interface.

works very well here (needs a minor #include to compile correctly, though)

I actually wonder why this isn't in the mainline kernel.
