Checking Registration of Fibre Channel Devices in 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.

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.
