Hey,
Check your /etc/rc.config.d/netconf anything strange for lan0?

Link lights? Maybe the port shutdown on the switch or the cable is dead?

Cheers

Hi,

I've checked SW and there is no issue, port is up and can ping to server without fail.

Thanks

Hi Naj,

If you are polling an IP and if your interface (lan0) can't reach this IP address then lan0 can become IP disabled. You can enable et with:

# cmmodnet -e lan0

By the way your cluster lock disk also seems down, you should check the availability of the disk.

Hi Cavdar

It's working fine now!!!
Many thanks for the command

But cluster lock disk still down do you have any idea on that?

Thanks

Hi again,
Check first /dev/disk/disk142 is available to system. (You can use ioscan -m lun command to check if the disk is online...)
