Fabriclog --show on an port shows SCN LR_PORT (0);g=0x19a

Fabriclog --show => output => SCN LR_PORT (0);g=0x19a, its an NPIV port with multiple wwns , i have several entries for an particular port , need to know why this alert shows, i know its a Link Reset alert, does this "SCN LR_PORT (0);g=0x19a" refer to any issue on flapping ports.

 

Switch: DCX

13:11:05.974880 SCN LR_PORT (0);g=0x19a                     D2,P0  D2,P0  216   NA   

 

i also have questions on how to identify LR_Port on a particularly NPV ports where there are multiple wwns, is there any specific command which gives more information.

Re: Fabriclog --show on an port shows SCN LR_PORT (0);g=0x19a

Hi,

 

In that output we can see how the device connected to port 216 performs a Link Reset.

 

This communication is, in this particular case, between the switch and the NPV device. the number of NPIV devices managed by the NPV device should not have to do with this events.

 

On the switch side, you could check the outputs of

sfpshow <slot/port> -f 

portshow <slot/port>

portstatsshow <slot/port>

Re: Fabriclog --show on an port shows SCN LR_PORT (0);g=0x19a

Hi Felpon,

 

              Thanks for your reply, but i have a question, this output below mentions a clear case of Port going to Offline and coming back Online, we normally check on abnormal behavior of ports and keep track of them using fabriclog command,

 

Switch 0; Mon Mar  4 21:46:10 2013 GMT (GMT+0:00)
21:46:10.604514 SCN Port Offline;g=0x6                      D2,P0  D2,P0  1     NA    
21:46:10.604532 *Removing all nodes from port               D2,P0  D2,P0  1     NA    
21:50:55.325314 SCN LR_PORT (0);g=0x6                       D2,P0  D2,P0  1     NA    
21:50:55.330373 SCN Port Online;g=0x6                       D2,P0  D2,P1  1     NA    
21:50:55.330543 Port Elp engaged                            D2,P1  D2,P0  1     NA    
21:50:55.330593 *Removing all nodes from port               D2,P0  D2,P0  1     NA    
21:50:55.330831 SCN Port F_PORT                             D2,P1  D2,P0  1     NA

 

But, why does an LR details of an particular NPV port has no details, could you help me explain this.

Re: Fabriclog --show on an port shows SCN LR_PORT (0);g=0x19a

That's becasue the NPIV device is not directly connected to the switch. Fabriclog only reports the changes in the ports directly connected to the Brocade switch. 

 

Changes in NPIV Devices connected to a NPV(or AG, IPT, etc) are not reported in fabriclog.
