Abstract
Error injection techniques involve, while a data storage system is in an error injection mode, injecting information representing an error of a storage device array into a first switch, such that the information representing the error is passed from a first downstream port of the first switch to a computing device through a second switch, the first and second switches being connected to the storage device array via downstream ports, and the first downstream port being connected to a second downstream port of the second switch; and determining error handling capability of the data storage system by obtaining a handling result of the information representing the error from the computing device. Accordingly, errors from storage devices can be simulated to facilitate detecting error handling in the entire I/O path comprehensively.
