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
- If you have a new HBA device installed on your computer, reboot the computer.
- Type the following command
# luxadmprobe
- Scroll down the listing to see the Fibre Channel device(s) and the related WWN(s).
Linux
and Windows
Boot a specific host, and not the bios version and the HBA card models connected to your host.
- 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.
- 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
HP-UX
- Determine the device name by typing the following command:
# ioscan -fnC fc
- 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.
- To determine the device name, type
# lscfg -|grep fc
- 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)
- 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)
- 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.
