Abstract
A method for error simulation in a data storage subsystem providing abstractions of one or more storage devices. The method includes dividing the data storage subsystem into two or more hierarchically organized subsystems, wherein the subsystems interact using IO Request Packets (IORPs), such that relatively higher level subsystems create and populate IORPs and pass them to relatively lower level subsystems for corresponding processing. The method further includes defining an IORP modifier configured to attach to matching IORPs based on one or more attributes of the IORP modifier and to modify at least one of the processing and one or more attributes of the IORP in order to simulate errors in the data storage subsystem.
