Determining Host Worldwide Names (Fibre Channel and SATA Only)

A P P E N D I X D

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

To Determine the HBA WWN

To Determine the FC Array WWNN

To Determine the FC Array WWPN

To Determine the HBA 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 HBA WWN on a Solaris host. To determine an HBA WWN, you must first display devices attached to that 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.

Screen capture showing the luxadm -e port and luxadm -e dump_map 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 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 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 command

# ioscan -fnC fc

All attached devices are displayed.

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 OS.

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 OS.

To Determine the FC Array 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 FC Array 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.

Note - The WWPN information is also included in the xml report generated by the console.
