Abstract:
A method for configuring a tape drive in a data processing system, said method comprising:initially powering up a tape drive; disabling a tape tension sensor in said tape drive while said tape drive performs a self-diagnostic test, said tape tension sensor having a sensor output line for transmitting an analog sensor signal proportional to a tape tension of a tape in said tape drive during normal operation; applying an increased direct current voltage to said sensor output line while said tape tension sensor is disabled, said increased direct current voltage being an indicator that any signal transmitted on said sensor output line while said direct current voltage is increased on said sensor output line is a configuration information signal describing said tape drive; transmitting a configuration information signal from said tape drive to a control system via said sensor output line while said sensor output line has said applied increased direct current voltage, said configuration information signal including a mechanical tension property of said tape tension sensor; comparing said configuration information signal to a stored predetermined pattern in said control system to determine if said tape drive is a new device; and updating a configuration for said tape drive if said tape drive is a new device.
