Embodiment Construction

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] In order to realize the above-mentioned functional connection on the same physical port, the npiv function can be enabled, and multiple logical ports can be virtualized on the same physical port. According to the FC protocol, the virtual wwpn number of the virtual logical port can be registered to the FC switch. , the FC switch will as...

Abstract

The invention discloses a method for virtualizing an FC port, which comprises the following steps: fictititiously generating a preset number of logical ports on a physical port by using an NPIV function; When a registration instruction is received, virtually generating a wwpn number containing preset identification information of a storage device for a logical port corresponding to the registration instruction by using an FC protocol, tegistering the wwpn number in the FC switch so that the FC switch assigns an fcid to the wwpn number. The wwpn number generated in the invention is composed ofpreset identification information of a storage device, thereby avoiding the situation that the wwpn number is generated by the FC card related information in the prior art. Thus, the failure of FC card and the need to replace the corresponding logical port wwpn number are avoided, so that a large number of front-end servers can not log in normally; The invention also discloses an FC port virtualization device, an FC terminal device and a computer-readable storage medium, which also have the beneficial effects.

Description

technical field [0001] The invention relates to the technical field of port virtualization, in particular to a method and device for FC port virtualization, FC terminal equipment and a computer-readable storage medium. Background technique [0002] The FC network is a fiber channel, also known as a mesh channel. There are generally two types of topologies for FC networks: FC-AL (arbitrated loop) and fabric (mesh switching matrix). The existing FC network topology is mainly based on the fabric topology. Here, port virtualization is also mainly aimed at the fabric topology. For a fabric network, FC terminal devices are connected to FC switches through cables. The ports connecting FC terminal devices to FC switches are called N (node) ports, and the corresponding ports on FC switches are called F (fabric) ports. Fabric network N Port virtualization technology is also known as NPIV. NPIV is the abbreviation of N_PortIdentifier Virtualization. NPIV can virtualize one HBA card ...
