How to simulate an Oracle RAC node down scenario to test Fast Connection failover ?

Other than normal shutting down  the instance on one of the node, can someone just methods to simulate the node down scenario with some simple commands on Linux ? No pulling out the plug is possible as the machines are located elsewhere.

I want to test the Oracle FCF by simulating a node outage situation. I want some easy methods to simulate the outage(not graceful outage) to prove the point.

Any pointers ?

Thanks

Could you please tell the commands to shutdown the NIC of the interconnect ?

Thanks Markgeer and Tolomir. I want to use the following commands in RAC to simulate abnormal outage in different combinations.

1) The linux commands(ifconfig or ifdown)  to bring down the network interface
2) lsnrctl to stop the listener service of the node to be put down
3) svrctl with (-o abort -i <instance>) option to bring down the node
4) Of course, shutting down the server itself

Thanks

1.) solved
2.) lsrnctl stop (as oracle user on the shell)
3.) http://www.rampant-books.com/art_hunter_rac_start_stop_cluster.htm
4.) shutdown -h now (as user root on the shell)   <-- don't try this remote ;-)
