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:
- If you have a new HBA device installed on your computer, reboot the
computer.
- Type the following command:
# luxadm -e port
All attached devices are displayed.
- Type the following command:
# luxadm -e dump_map
The output displayed includes HBA port
and node WWNs.
Linux and Microsoft Windows OS
The following steps explain how to determine the HBA WWN on a Linux and
Microsoft Windows host:
-
Boot a specific host, and not the bios version and 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 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.
- Determine the device name
by typing the following command:
# ioscan -fnC fc
- Type the following command:
fcmsutil/device name
The output displayed includes
HBA port and node WWNs.
IBM AIX OS
The following steps describe how to determine the HBA WWN on an IBM AIX
host.
- Determine the device name by typing the command:
# lscfg |grep fc
- Type the following command:
# lscfg -vl device name
The output
displayed includes the network address, which is the HBA WWN.
Determining the FC Array Worldwide Node Name (WWNN)
- 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)
- Double-click the array icon in the main window, or select it and choose
View > View Controller.
-
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.
