A step in the HACMP test plan is to gracefully stop the cluster on a node and to verify that the Shared resources fallover to the standby node. To prepare for this testing step， both nodes in the two-node cluster are in a stable state with the single resource group active on Node ’A’. Which of the following is the best way to execute this portion of the test plan？（）
- A Execute "lssrc -g cluster stop" on Node ’A’
- B Execute "cat /etc//motd >/dev/kmem" on Node ’A’
- C Execute "/usr/es/sbin/cluster/utilities/sclstop -gr" on Node ’A’
- D Find the pid of cluster manager daemon on Node ’A’ and issue a "kill-9" against the pid
