This document provides an orderly set of steps to follow when troubleshooting controller problems for Sun Storage 3000 Arrays.
Before replacing a controller, confirm overall array health . Other components and/or conditions may have caused the current controller state. Most controller failures are caused by firmware detected problems and not actual controller hardware problems. Generally speaking, the controller should be one of the very last components replaced.
