Determining Host Worldwide Names (Fibre Channel Only)

This appendix explains how to determine the host worldwide name (WWN), worldwide node name (WWNN), and worldwide port name (WWPN) of a FC array. Steps include:

To Determine the WWN

To Determine the WWNN

To Determine the WWPN

To Determine the WWN

Prior to using the LUN Filter feature, it is helpful to identify which Sun StorEdge 3510 Fibre Channel array is connected to which HBA card, and the 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 probe

3. Scroll down the listing to see the Fibre Channel device(s) and the related WWN(s).

Linux and Microsoft Windows OS

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

1. Boot a specific host, and note 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 which 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).

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

To Determine the WWNN

1. Double-click the array icon in the main Configuration Service window, or select it and choose View right arrow 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.

To Determine the WWPN

1. Double-click the array icon in the main Configuration Service window, or select it and choose View right arrow 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.
