If you want the application software to control library operations, you
must set the library to SCSI Interface mode. In this standard operating
mode, the application software controls the motion of the CHM by
issuing SCSI commands across the SCSI bus.

The application software can issue commands to the library
regardless of the control mode. However, the library must be in
SCSI Interface mode for the application software to control
CHM motion.
For detailed information about SCSI commands, refer to the
Scalar AIT
220 Library SCSI Reference Manual.

If you want the library to run as a sequential stacker device, you can set
the library to one of three sequential modes:
S Sequential 1
S Sequential 2
S Dual Sequential
In these modes, the application software does not need to provide support
for library functions, only for the tape drives. For detailed information
about the sequential modes, see Appendix K.
