Abstract
A storage controller (104) for a storage system (100) in which there are multiple storage devices (109) and a method for recording diagnostic information are provided. The storage controller (104) includes a storage device manager (203) which has means for allocating a storage device (109) in the storage system (100) for storing diagnostic data. The storage controller (104) also includes means for generating diagnostic data regarding the operation of the storage controller (104). Two buffers (207, 208) are used for alternately recording and writing batches of diagnostic data to the allocated storage device (109). The allocated storage device may be a storage device which is normally reserved for disaster recovery in the storage system (100).
