When adding an FC initiator to an initiator group, which identifier should be used?

When adding a Fibre Channel (FC) initiator to an initiator group, the appropriate identifier to use is the HBA Worldwide Port Name (WWPN). The WWPN is a unique identifier assigned to each Fibre Channel port on a Host Bus Adapter (HBA). It allows the storage system to recognize and manage the connection between the initiator (server) and the storage array effectively.

The use of the WWPN is essential because it ensures that the storage system can differentiate between multiple initiators and establish the appropriate communication paths. Proper identification via the WWPN is crucial for implementing security and access controls within the SAN (Storage Area Network) environment, enabling specific initiators to access designated storage resources.

The other identifiers mentioned have distinct purposes. The Logical Unit Number (LUN) refers to the specific logical storage unit presented by the storage system and is not used for identifying initiators. The Network Interface Card ID (NIC ID) pertains to network interfaces in Ethernet environments, not Fibre Channel, and is therefore not applicable for FC initiators. Device Alias Name is typically a human-readable label for a device but does not serve as a unique identifier for FC connections. Hence, using the WWPN is the correct approach for adding an FC initiator to
