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.

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

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

Re: /dev/sch0 interface

[Matthew Jacob]

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

/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
