US Patent 7743283 Dynamically modifying parameters for servicing of storage devices

A storage management module is described herein for servicing, according to servicing parameters, storage devices of a storage system that are exhibiting errors, the servicing parameters being contained and read from an external parameters file (rather than being encoded as instructions in the storage management module). By using an external parameters file, the servicing parameters can be easily modified by reading a new file having modified parameters without requiring modification of the code instructions of the storage management module. The parameters file may comprise monitoring or testing parameters, such as error thresholds and recommended actions upon reaching an error threshold, wherein the parameters vary depending on storage device type or error type. The parameters file may be stored at a predetermined location on the storage system, whereby the storage management module may be configured to periodically examine the predetermined location to locate and read new parameter files (having modified parameters).
