Determining Host Worldwide Names, Worldwide Node Names, and Worldwide Port Names (Fibre Channel Only)

Determining the Worldwide Name

Prior to using the LUN Filter feature, it is helpful to identify which array is connected to which HBA card and the worldwide name (WWN) assigned to each card.

Solaris

  1. If you have a new HBA device installed on your computer, reboot the computer.
  2. Type the following command

    # luxadmprobe

  3. Scroll down the listing to see the Fibre Channel device(s) and the related WWN(s).
  4. Screen shot showing the 
luxadm probe command used to display Fibre Channel device WWNs.

Linux and Windows

  1. Boot a specific host, and not the bios version and the HBA card models connected to your host.

  2. Access the HBA card's bios with the appropriate command (alt-q or control-a are commonly used). If the host has multiple HBA cards, select the card that is connected to the storage.
  3. Scan the card to look for devices attached to it (usually with the Scan Fibre Devices or the Fibre Disk Utility).
  4. The node name (or similar label) is the worldwide name.

    Example with a Qlogic card:

    
    ID     Vendor     Product          Rev       Node Name               Port ID
    0      Qlogic     QLA22xx Adapter  B         210000E08B02DE2F        0000EF 
    
    

HP-UX

  1. Determine the device name by typing the following command:

    # ioscan -fnC fc

  2. Type the following command:

    fcmsutil/device name

    Output similar to the following is displayed:

IBM AIX

The following step describes how to determine the WWN on systems running IBM AIX.

  1. To determine the device name, type

    # lscfg -|grep fc

  2. Type the following command

    # lscfg -vl device name

Output similar to the following is displayed. The Network Address is the WWN.

Determining the Worldwide Node Name (WWNN)

  1. Double-click the array icon in the main window, or select it and select View > View Controller.

    The Node name is displayed in the Node name field in the View Controller Configuration window.

    NOTE: The WWNN information is also included in the xml report generated by the console.

Determining the Worldwide Port Name (WWPN)

  1. Double-click the array icon in the main window, or select it and select View > View Controller.

    The RAID Controller Parameters window is displayed. On the Channel tab, scroll all the way to the right to display the WWPN.

    NOTE: The WWPN information is also included in the xml report generated by the console.
