Getting the Connected Device WWNs Using the PowerVault 5xF Fibre Channel Switch Name Server Table

Zoning is required in heterogeneous SAN configurations to separate incompatible environments, such as separating Windows environments and storage from NetWare environments. It may be used in other configurations depending on the components and environments in your SAN. Zoning uses World-Wide Names (WWNs) to uniquely identify each target device in a SAN.

You can obtain the WWNs of devices that are connected to each switch by using the nsShow command through a Telnet or serial session. This command lists the con- tents of the name server table in the switch. The list of WWNs are sorted by the physical port number to which the devices are connected. (The position in the name server table listing does not identify the physical port to which the device is con- nected.) The WWN listing shows both the port and node WWNs. This method of obtaining the WWNs is recommended if the fabric contains only PowerVault 50F switches; however, it can be used for PowerVault 51F and 56F switches as well.

In a fabric with a PowerVault 51F or 56F switch (running version 2.1.x firmware), the name server information for the entire fabric can be accessed from the Dell PowerVault Switch Manager application program using a Web browser. To access the name server information, start the Switch Manager application program by connect- ing to a PowerVault 51F or 56F switch through a Web browser (see the Dell PowerVault Switch Manager User’s Guide for more information). From the Fabric View page (the first page displayed in the browser), click the Name Server Table button to launch the Name Server Table View. The table displays the port and node WWNs of each device in the fabric, the switch to which the device is connected (identified by domain ID), and the physical port to which the device is connected. The Name Server Table View also identifies zone membership information for the device.

The following WWN information can be used to identify each type of device that is connected to a switch:

•xx:xx:00:60:69:xx:xx:xx — PowerVault 50F, 51F, or 56F switch

•xx:xx:00:60:16:xx:xx:xx — PowerVault 650F storage processor

•xx:xx:00:80:e5:xx:xx:xx — PowerVault 660F storage system

•xx:xx:00:e0:8b:xx:xx:xx — QLA2100/2200 HBA

•xx:xx:00:e0:02:xx:xx:xx — PowerVault 35F bridge

•xx:xx:00:b0:d0:xx:xx:xx — PowerVault 530F SAN appliance

For more information on using WWNs when configuring zones, see Chapter 15, “Managing Fibre Channel Fabric Switch Zones.”
