Abstract
Methods and systems for processing task management requests are provided. A cache client adapter receives a task management request other than an abort for a logical storage object owned by a cache owner adapter and determines if there are any pending input/output (I/O) requests associated with the storage object. The cache client adapter sends an abort request to the cache owner adapter when there are pending I/O requests and sends the task management request directly to a controller that manages a storage device whose space is presented as the logical storage object; and sends only the task management request to the controller when there are no pending I/O requests for the logical storage object.
