Jason's new and improved chg-scsi documentation.
This documentation will also include an occasional reference to the mtx suite
as I have attempted to use chg-zd-mtx. I use mtx often as a fast query tool.

+Please also refer to Amanda_Tape_Changer_Support for additional details.
My equipment list is as follows:
* Redhat 7.0 machine
I base this documentation on the following:
* mtx version 1.2.16rel
-* AMANDA version 2.4.3b3
+* Amanda version 2.4.3b3
* SCSI2 specification: X3T9.2/375R revision 10L
* Quantum/ATL Field Service Manual 6321101-03 Ver.3, rel.0
* Quantum DLT800 Tape system product manual 02 April, 2001 81-60118-04
Note that Quantum/ATL's L-series changers follow the SCSI command set, and do
not use any proprietary commands. Thus, it was fairly simple to make this work.

Please note that my usage of "barcode" and "barcode reader" throughout this
document really refers to "physical tape identification system". for example:
the EEPROM in the AIT cartridge.

this command takes either a slot number, or any one of the following: current,
next, prev, first, last, advance

this only should be used if a barcode reader is present, or emulate barcode is
turned on.

I believe the fallback is to search the entire magazine.

the cleaning cartridge is in is not available for any other use.

eg: /dev/nst1> set debug to 9:0

I set SCSItapedev to /dev/sg0 to test with, then ran chg-scsi -info. Check the
chg-scsi debug file for tapeidentification details. This is where I discoverd
