Abstract: A METHOD, SYSTEM, AND APPARATUS FOR MANAGING A FAILED INPUT/OUTPUT ADAPTER WITHIN A DATA PROCESSING SYSTEM (100) IS PROVIDED. IN ONE EMBODIMENT, AN OPERATING SYSTEM HANDLER (204) RECEIVES AN INDICATION THAT ONE OF A PLURALITY OF INPUT/OUTPUT ADAPTERS (222-228) HAS FAILED.THE OPERATING SYSTEM HANDLER CONSULTS AN ERROR LOG (300) TO DETERMINE WHICH INPUT/OUTPUT ADAPTER HAS FAILED. ONCE THE BAD INPUT/OUTPUT ADAPTER HAS BEEN DETERMINED, THE OPERATING SYSTEM HANDLER DISABLES THE BAD INPUT/OUTPUT ADAPTER AND DEALLOCATES ANY PROCESSES BOUND FOR THE BAD INPUT/OUTPUT ADAPTER WITHOUT POWERING DOWN THE DATA PROCESSING SYSTEM. A USER IS THEN NOTIFIED OF THE BAD INPUT/OUTPUT ADAPTER SO THAT THE BAD INPUT/OUTPUT ADAPTER CAN BE REPLACED. THE INPUT/OUTPUT ADAPTER MAY BE REPLACED WITHOUT POWERING DOWN THE DATA PROCESSING SYSTEM.ONCE THE BAD INPUT/OUTPUT ADAPTER HAS BEEN REPLACE, THE NEW INPUT/OUTPUT ADAPTER IS ENABLED.(FIG 1)
