| 1. A simulated data storage medium insertion/ejection system, comprising:
an import/export station having a plurality of I/O slots adapted to transfer storage media to and from a storage library,
wherein at least one I/O slot is full and at least one I/O slot is empty;
a memory device for storing a variable having a value representing a status of each of the plurality of import/export station
I/O slots;
a processor in communication with the memory device; and
a sensor for detecting the status of each import/export station I/O slot in communication with the processor;
wherein the processor is adapted to ascertain a correct value of the variable for each import/export I/O slot using said sensor,
modify the value of the variable so as to be inconsistent with the status of the import/export station I/O slot and to simulate
an opening and closing of a door of the import/export station I/O slots, thereby triggering a scan by the sensor of the-import/export
station I/O slots to determine the status of each of the plurality of import/export station I/O slots;
wherein the processor is further adapted to update the value of the variable so as to be consistent with the status of the
import/export station I/O slots based on said scanning; and
wherein the processor is further adapted to report the update of the value of the variable to an external device.
