WWN, or World Wide Name, is a unique identifier assigned to each Fibre Channel (FC) port or iSCSI adapter. It is used to identify the port or adapter in a storage area network (SAN) or iSCSI network.
There are two types of WWNs: node WWNs and port WWNs. Node WWNs identify the storage system or server, while port WWNs identify the individual ports on the storage system or server.
WWNs are important because they allow SANs and iSCSI networks to identify and communicate with each other. They are also used to configure and manage storage devices.
There are several ways to check the WWN of a port or adapter in Windows. One way is to use the Command Prompt. To do this, open a Command Prompt window and type the following command:
wmic path FCPort get WWNThis command will display the WWN of each FC port on the computer.
Another way to check the WWN is to use the Device Manager. To do this, open the Device Manager and expand the “Fibre Channel Ports” or “iSCSI Adapters” section. Then, right-click on the port or adapter and select “Properties”. The WWN will be displayed in the “Details” tab.
