More Information
Summary:A host system operates to manage a storage device. The host system initiates an abort of a command when the command has been fetched from a submission queue (SQ) of the host system and the SQ entry has been fetched from the SQ and the host system has not received a corresponding command completion response from the storage device. The host system sends an abort request to the storage device, and issues a cleanup request to direct a host controller to reclaim host hardware resources allocated to the command. The host system adds a completion queue (CQ) entry to a CQ and sets an overall command status (OCS) value of the CQ entry to indicate completion of the abort request.
