A processor of the computing system executes an OS controlling a hardware device and a storage program operating on the OS and using the hardware device via the OS. The OS identifies an error status of the hardware device when receiving a notification of an error that has occurred to the hardware device, and notifies the storage program that operates on the OS of the error status when the error status satisfies a predetermined condition. The storage program determines error handling on the hardware device on the basis of the error status, and requests the OS to perform the determined error handling. The OS performs the determined error handling on the hardware device.
