To operate DATA ONTAP 8.1 Cluster Mode SAN, what must be configured on both the initiator and the target?

Logical Unit Access Initialization is not a defined SAN protocol or configuration standard; it does not exist in the iSCSI, FC, or FCoE specification sets.

Physical Unit Access Initialization is not a real SAN configuration term and does not correspond to any protocol used in Data ONTAP SAN environments.

Symmetric Logical Unit Access (SLUA) treats all paths as equal priority, which is incompatible with Cluster Mode where paths have different access characteristics depending on LUN ownership.

Asymmetric Logical Unit Access (ALUA) must be configured on both the initiator and the target in Cluster Mode SAN because LUNs can be accessed through both the owning node (optimized path) and a partner node (non-optimized path). ALUA provides the mechanism for the host to discover these path states and prioritize traffic correctly, which is fundamental to Cluster Mode's distributed architecture.

SAN Access Initialization Protocol is a fabricated term that does not correspond to any real SAN standard or ONTAP configuration requirement.
