Determining Host Worldwide Names, Worldwide Node Names, and Worldwide Port Names (Fibre Channel and SATA 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 OS

The following steps explain how to determine the WWN on a Solaris host:

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

    # luxadm -e port

    All attached devices are displayed.

  3. Type the following command:

    # luxadm -e dump_map

    The output displayed includes HBA port and node WWNs.

  4. Screen shot showing the 
luxadm commands used to display Fibre Channel device WWNs.

Linux and Microsoft Windows OS

The following steps explain how to determine the HBA WWN on a Linux and Microsoft Windows host:

  1. Boot a specific host, and not the bios version and 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 HBA worldwide name.

    Example with a Qlogic card:

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

HP-UX OS

The following steps describe how to determine the HBA WWN on an HP-UX host. To determine an HBA WWN, you must first display devices attached to that host.

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

    # ioscan -fnC fc

  2. Type the following command:

    fcmsutil/device name

    The output displayed includes HBA port and node WWNs.

    Screen capture showing the output from running the fcmsutil command to display the WWN on systems running the HP-UX environment.

IBM AIX OS

The following steps describe how to determine the HBA WWN on an IBM AIX host.

  1. Determine the device name by typing the command:

    # lscfg |grep fc

  2. Type the following command:

    # lscfg -vl device name

    The output displayed includes the network address, which is the HBA WWN.

    Screen capture showing the output from running the lscfg -vl command to display the WWN on systems running the IBM AIX environment.


Determining the FC Array Worldwide Node Name (WWNN)

  1. Double-click the array icon in the main window, or select it and choose 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 FC Array Worldwide Port Name (WWPN)

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

  2. Click View Controller Parameters.

    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.
