Abstract
A method and system for handling errors on an Input/Output (I/O) link of a system is provided. The link is being shared by a plurality of devices of the system; each device may be shared by one or more operating systems. The method of error handling during configure of the system includes steps of checking a device for an error during configuration of the system and restricting the device from being configured, if an error is detected. The method includes the steps of examining the device capabilities to recover from errors, and; configuring the device in a first mode if the device has capabilities to recover from errors, else configuring the device in a second mode or not configuring the device. Further the handling of error may also be performed during runtime of the system, for doing so the step of checking is followed by a step of isolating and deleting the device if value of a number indicative of errors encountered for the device is greater than a threshold value. Else the method provides step of initiating a recovery process for the device and reporting result of the recovery process.
