Name Server
Entering the "nsshow" command on the console allows current fibre channel devices registered in
the name server for FC Switch Modules to be known.
Type "nsshow" on the console.

„ Check that the "nsshow" command can show various information on fibre channel
devices linked up to FC Switch Modules.
If the information on a connected device does not appear, the device, SFP module or
FC cable may be defected.
„ For details of the displayed information, refer to the User’s Guides of the connected
fibre channel devices.
Information displayed by "nsshow"
Item Display
Type Indicates port status.
" N," "NL", and "U" mean N_Port, NL_Port and unknown status, respectively.
PID Indicates the 24-bit ID of each fibre channel device.
Consists of a 6-digit value in the format of "xxyyzz" as follows:
xx: Domain ID of switch
yy: Port number (hexadecimal notation)
zz: Loop ID ("00" in fabric connection)
PortName Indicates the world wide port name (WWPn) of each connected fibre channel device.
NodeName Indicates the world wide node name (WWNn) of each connected fibre channel device.
„ "nsshow" allows you to know WWPn’s of fibre channel devices connected to FC Switch
Modules. WWPn’s can be used for various settings of peripherals.
„ Depending on the type of the OS you use, "PID" has some influence on the hardware
path of the logic with which the OS recognizes disk array units. Take sufficient note on
the PID if a job is done to change the PID after system operation is started.
