A storage subsystem, method of automatically maintaining the subsystem hardware configuration up to date and program product therefor. The storage subsystem automatically initiates hardware discovery in response to a triggering event. Subsystem hardware information is collected during hardware discovery and checked against a current configuration to identify hardware changes. Whenever hardware changes are identified, the subsystem configures the hardware and calibrates newly configured hardware. So, hardware changes may be automatically discovered, configured and calibrated free from operator intervention.
