Abstract
Error recovery is performed when an error rate for a subsystem of a computer environment (e.g., an Input/Output (I/O) subsystem) is greater than a predefined value and a critical resource of the computer environment (e.g., storage) is experiencing a shortage. Error recovery may include slowing down activity of the devices associated with the subsystem and/or simulating errors for the subsystem. The simulation of the errors does not require a large block of additional storage, and thus, the shortage situation is not exacerbated.
