- *
- * chg-scsi-chio.c -- generic SCSI changer driver
- *
- * This program provides a driver to control generic
- * SCSI changers, no matter what platform. The host/OS
- * specific portions of the interface are implemented
- * in libscsi.a, which contains a module for each host/OS.
- * The actual interface for HP/UX is in scsi-hpux.c;
- * chio is in scsi-chio.c, etc.. A prototype system
- * dependent scsi interface file is in scsi-proto.c.
- *
- * Copyright 1997, 1998 Eric Schnoebelen <eric@cirr.com>
- *
- * This module based upon seagate-changer, by Larry Pyeatt
- * <pyeatt@cs.colostate.edu>
- *
- * The original introductory comments follow:
- *
- * This program was written to control the Seagate/Conner/Archive
- * autoloading DAT drive. This drive normally has 4 tape capacity
- * but can be expanded to 12 tapes with an optional tape cartridge.
- * This program may also work on onther drives. Try it and let me
- * know of successes/failures.
- *
- * I have attempted to conform to the requirements for Amanda tape
- * changer interface. There could be some bugs.
- *
- * This program works for me under Linux with Gerd Knorr's
- * <kraxel@cs.tu-berlin.de> SCSI media changer driver installed
- * as a kernel module. The kernel module is available at
- * http://sunsite.unc.edu/pub/Linux/kernel/patches/scsi/scsi-changer*
- * Since the Linux media changer is based on NetBSD, this program
- * should also work for NetBSD, although I have not tried it.
- * It may be necessary to change the IOCTL calls to work on other
- * OS's.
- *

- * documentation. The author makes no representations about the
- * suitability of this software for any purpose. It is provided "as is"
- * without express or implied warranty.
- *
- * Michael C. Povel 03.06.98 added ejetct_tape and sleep for external tape
- * devices, and changed some code to allow multiple drives to use their
- * own slots. Also added support for reserverd slots.
- * At the moment these parameters are hard coded and only tested under Linux
