World Wide Name (WWN) for a fibre channel HBA on Windows Server

There are many ways to find the World Wide Name (WWN) of fibre channel HBA connected to server running windows server operating system.

Few model dependent utilities are:

  1. HBAnyware utility (Emulex)
  2. SANsurfer utility (Qlogic)

For any other model of HBAs, the  Fibre Channel Information Tool utility (FCINFO.EXE) can be used. The fcinfo tool is available for download from Microsoft Download web site. It works on Windows Server 2003 and Windows server 2000 systems, However, Installation of the Fibre Channel Information Tool is not mandatory, but three core files (FCINFO.EXE, HBAAPI.DLL and HBATAPI.DLL) must be copied in a common folder in order to run the tool. For Windows 2008 R2, You can use Storage Explorer to see detailed information about the Fibre Channel host bus adapters (HBAs) on the server.

Running the Fibre Channel Information Tool at a command line with no arguments will give basic information (including WWN) about all the installed host bus adapters (HBAs):

C:\>fcinfo

There are 2 adapters:

com.qlogic-QLA2300/2310-0: PortWWN: 21:00:00:e0:8b:08:95:df \\.\Scsi2:

com.emulex-LP9002-1: PortWWN: 10:00:00:00:c9:30:d0:17 \\.\Scsi3:

For Help,

type FCINFO /? or FCINFO /?? You will get a long list of commands, many of which are very task specific and not necessary for information gathering.
