Abstract
Embodiments for server port virtualization for guest logical unit number (LUN) masking in a host direct attach configuration using a storage adapter in a computing environment by a processor. An F switch port is simulated by an N storage port to enable either N-port virtualization (NPV) or N-port identification (ID) virtualization (NPIV) in the host direct attach configuration by directly attaching the N server port to the N storage port. A domain name system (DNS) operation is performed to cause each virtualized N-port ID to be mapped to fiber channel (FC) IDs in domain format of domain, area, port.
