2.1.7.3 Diagnostic Manager
The diagnostic manager controls all self testing of the library. Most of its
functionality is executed automatically at power-up without user interaction. The
user can access some of the functionality of the diagnostic manager through the
front panel or the SCSI send diagnostic command. See Section 4.8, “Running an
Internal Test,” on page 4-10.
2.1.7.4 Motion Manager
The motion manager communicates with the drive as necessary and receives all
motion command requests, breaking them into move steps. The motion manager
then issues commands to the transport motor controller. The motion manager is also
responsible for any error recovery attempts and reports the results to the front panel,
diagnostic, and interface managers.
2.1.7.5 Transport Motion Controller
The transport motion controller controls the loader, which performs individual move
steps.
