You have been asked to conduct a high-level inventory of a remote fibre channel SAN fabric. Your manager is worried that the remote site may include HBAs manufactured from a now bankrupt vendor. What

HBA Port Mode (e.g., F-port, N-port) describes the operational state or type of port connection, but it does not contain vendor-specific information.

The AL_PA (Arbitrated Loop Physical Address) is an identifier used in Fibre Channel Arbitrated Loop topologies and does not indicate the HBA's vendor.

The FC_ID (Fibre Channel ID) is a 24-bit address dynamically assigned by the fabric to a device for routing purposes and does not carry vendor-specific information.

The World Wide Port Name (WWPN) is a globally unique 64-bit identifier assigned to each Fibre Channel port. The first 24 bits of a WWPN contain an Organizationally Unique Identifier (OUI) which is registered to the HBA manufacturer, allowing direct identification of the vendor.
