Abstract
A method for collecting diagnostic information associated with an error is disclosed. In one embodiment, such a method includes detecting an error condition associated with mirroring data from a primary volume to a secondary volume. In response to detecting the error condition, the method modifies various diagnostic parameters to improve collection of diagnostic information. The method then immediately re-drives the data from the primary volume to the secondary volume. This will ideally recreate the error. Upon recreating the error, the method captures diagnostic information associated with the error in accordance with the modified diagnostic parameters. A corresponding system and computer program product are also disclosed.
