3. Find the cause of the error:

Check the IP address on node 1. the VIP does not exist.
$ Ifconfig-
En0: flags = 1e080863, 480

From the output, we can see that the VIP address of Node 1 has been moved to node 2, so as to determine that node 1 has been detached from the cluster.
Use "ifconfig" to view ip information on node 2.

4. Problem Solving:
Clear the configuration information of Node 1 and try to run root. sh again.
