Which NetApp feature presents LUNs only within the HA pair?

Selective LUN Mapping (SLM) is the feature that presents LUNs only within the HA pair. SLM allows administrators to control which LUNs are visible to which hosts, ensuring that LUNs are only accessible through the designated HA pair, thus improving security and manageability.
