Finding the World Wide Name (WWN) in Windows Server 2008 and 2008 R2

You know how it is, you just built that new server and you need to attach storage to the Qlogic or Emulex card and the storage guys are asking for the WWN (World Wide Name) and if this is a first time you start to scratch your head, no worries because Microsoft has added that little piece of info right at your finger tips.

In Windows Server 2008 or 2008 R2, you can use “Storage Explorer” to show the WWN.

  • Open MMC (Microsoft Management Console)
  • Click File > Add / Remove Snapin.
  • Find Storage Explorer and double-click to add the snapin. Click ok to save and go back to the screen. The system will scan for adaptors.
  • Expand Servers > <Server Name>.
  • Click on the adaptor and the information will be displayed.

    Ok. That is dandy and thank you. However, I want to give a couple disks back to the SAN guys, and I need the WWN of the hdd, not the HBA…

    How do I determine what lun = what drive? i.e. Disk 7 in diskman is ?? lun?
