Well tell us a bit more about your configuration...

ioscan -funC lan

lanscan

netstat -in

netstat -rn

...where are you pinging from? What IP address?

Hi Ajin,

There are many possiblity for not pinging. Are you setting up this first time or it's working earlier and not working now?

To which ip you are pinging? Is it pinging locally?

Just start with linkloop.

#linkloop -i

Example for lan0
#linkloop -i 0
Link connectivity to LAN station: 0x001083F7EFCD
-- OK


-> if the output is like above then cable is connected to it. Then check the linkloop connectivity with remote host. If you get error that means there is no cable connectivity.

#linkloop -i

Example for lan0
#linkloop -i 0
You will get same output like above means physical connectivity between the local server to remote server is ok.

If physical connection is ok then move to other steps.

Check the routing entries if you are trying to ping other network.

check the hardware status using ifconfig command.

#ifconfig lan0

It is also possible that you lan interface card may faulty. that should be last resort..

Hi Ajin,

There was a typo error...

#ifconfig lan0 -->will give the software status of the card not the hardware status.

apologize for the mistake

Hi

You can check with the command fcmsutil /dev/tdX .It will show the status of the fibre channel is online or ofline and check the card is claimed or unclaimed with ioscan command ioscan -kfnC fc and check the fibre card.Check the speed of the fibre card might be issue with the speed too.
