METHOD, SYSTEM AND COMPUTER PROGRAM PRODUCT FOR CONTROLLING HARDWARE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method, a system and a device for managing a failed input-output adapter in a data processing system. SOLUTION: An operating system handler receives an instruction that one of a plurality of input-output adapters fails. The operating system handler checks an error log to decide which input-output adapter fails. When the operating system handier decides the failed input-output adapter, the handler disables the failed input-output adapter without powering down the data processing system and releases all pieces of allocated processing going to the failed input- output adapter. Next, a user is notified of the failed input-output adapter so that the user can replace the failed input-output adapter. The input-output adapter can be replaced with a new input-output adapter without powering down the data processing system. When the failed input-output adapter is replaced, the new input-output adapter is enabled.
