Systems and methods provide zone management for devices in a Serial Attached Small Computer System Interface (SAS) topology. In one embodiment, a zone management device stores a zone map that identifies an initial zone of a device in the topology. The management device detects changes in the topology, and identifies a current zone of the device subsequent to the change in the topology. The management device compares the zone map for the device to the current zone to identify a change in the zone of the device, and generates a message for an expander in the topology based on the change in the zone. The management device then transmits the message to the expander to restore the zone of the device to the initial zone.
