Abstract
A method and system for reading exception data by a storage server from a storage controller. An exception event is detected at the storage server. The storage server registers with the controller, such that only one storage server can read the exception data at a time. If the storage server is registered with the controller, the storage server reads the exception data. If the storage server does not successfully register with the controller, the controller keeps track of which storage servers have not read the exception data, to ensure that all storage servers can read the data.
