Abstract
Methods and structure for improved configuration management of a storage system. A storage system comprises one or more storage controllers coupled with a plurality of storage components (e.g., storage devices and switching components). The coupling often comprises a switched fabric communication structure. Configuration changes normally propagated throughout the components of the networked storage system are prevented by detecting temporary changes in the configuration that are restored to the original configuration within a predetermined period of time. In a Serial Attached SCSI (SAS) storage system, SAS expanders and initiators of the network may be enhanced in accordance with features and aspects hereof to prevent propagation of BROADCAST(CHANGE) primitives when a temporary configuration change is restored within the timeout period. Configuration changes may include temporary loss of link communications for a link of the expander and/or removal and insertion of a storage device coupled with the expander.
